Diaphragmatic excursion - Wikipedia Extubation failure increases mortality, infections, ICU length of stay and costs [2,3]. Related Articles. Breath sounds decreased or absent, voice sounds decreased or absent. Answers - Loyola University Chicago diaphragmatic pressure measurements [7]. The diaphragm is the major muscle of respiration. The mean diaphragmatic excursions of the two hemidiaphragms have been determined for men and women (Table 1). Find the level of the diaphragmatic dullness on both sides 38. Decreased chest excursion at the base of the lungs is characteristic ofCOPD.Thisisdueto decreased diaphragmatic function. Considering the proximity of the phrenic nerves to multiple cardiac structures3 critical to arrhythmia initiation and maintenance, it is unsurprising that phrenic nerve injury has been reported after ablation of various Physical examination of Respiratory Assessment Chest physical examination 2 Assess the Diaphragmatic Thickness Fraction and Diaphragmatic Excursion in preterm infants [ Time Frame: 1 year ] Assessment of Diaphragmatic Thickness in millimetres. Diaphragmatic excursion was measured twice at each time point by a single well-trained expert (K.K.) Introduction. May be abnormal with hyperinflation, atelectasis, the presence of a pleural effusion, diaphragmatic paralysis, or at times with intra-abdominal pathology. Breath sounds shift from vesicular to bronchial when there is is fluid in the lung itself (pneumonia). 3. Learn Ventilators There was a statistically significant positive correlation between 6MWT and diaphragmatic excursion (P=0.020) (Table 6). This runs counter the current discussion on lung protective ventilation however, which suggests that low tidal volumes are beneficial to the patient. The sequelae from diaphragmatic rupture and subsequent herniation of intra-abdominal contents are associated with significant morbility and mortality[1-3]. Is 4-6 centimetres between full inspiration and full expiration. Post-step test sonographic evaluation demonstrated an increase in diaphragmatic excursion with a significant time and group interaction (F (4,72) = 5.499, p = 0.005). The diaphragm inspiratory excursion, (in cm) can be divided by the inspiratory time (in second) to obtain the diaphragm inspiratory mean velocity (in cm/s). Diaphragm ultrasound scanning technique is best practiced on healthy volunteers who are able to follow breathing commands and can tolerate scanning of the neck. Traumatic Pneumothorax Detailed History of Presenting Illness (HPI) As relevant to a motor vehicle accident: -Bruised chest -Painful area of ribs -Shortness of breath -Lacerations consistent with road trauma (eg. Diaphragmatic excursion and chest wall expansion increases the negative intra-thoracic pressure required for inhalation. The level of dullness (diaphragmatic excursion) should go down 3-5cm symmetrically. 24 hr post-operative VAS was 2.3/10 with no opioid analgesics being prescribed. A cut-off value of 2.95cm for diaphragmatic excursion was assigned with 83.7% sensitivity and 70.6% specificity to differentiate mild and moderate COPD from severe and very severe cases. When the sound changes to a dull note, it Chemical sclerosis of the pleural space is used to prevent recurrence of spontaneous pneumothorax. In eight cases (25%), the catamenial character of the pneumothorax was recognized by clinical history. 7 With regard to complications, barotrauma parameters including pneumothorax, surgical emphysema, and reduced air entry were also recorded. Diaphragmatic ultrasound excursion and thickness have been shown to be variously affected in subjects admitted to the emergency department with AHRF. Normal diaphragmatic excursion should be 35 cm, but can be increased in well-conditioned persons to 78 cm. Methods. The fluoroscopic sniff test, also known as diaphragm fluoroscopy, is a quick and easy real time fluoroscopic assessment of diaphragmatic motor function (excursion).It is used most often to confirm absence of muscular contraction of the diaphragm during inspiration in patients with phrenic nerve palsy or breathing difficulties following stroke.Chest radiograph The diaphragm muscle appeared as hypoechoic structure between the diaphragmatic pleura and peritoneal pleura (the two echoic lines) (arrow). Start at the apices of the scapulae and percuss across the tops of both shoulders. trauma, or pneumothorax (air in thepleuralspace). sclerosis, diaphragmatic excursion was signi6cantly less on the sclerosed side than on the contralateral side (10.71.3 vs 17.31.7 mm, mean :t SEM; p<.OI). Diaphragmatic excursion is the movement of the thoracic diaphragm during breathing. Pneumothorax Background Diaphragmatic hernia is a rare life-threatening condition affecting 35 % of all the trauma patients admitted to the hospital [1, 2]. INTERVENTIONS During spontaneous breathing trial, each hemidiaphragm was evaluated by M-mode ultrasonography using the liver and spleen as windows with the patient supine. What is rhoncial fremitus? The base of each lung is broad and concave, resting on the convex surface of the diaphragm. Diaphragm Excursion-Time Index: A new parameter using ultrasonography to predict extubation outcome, by Atul Palka et al. Diaphragm ultrasound can assess for muscle size, thickening with respiration, and excursion. After the start of carbon dioxide-induced pneumoperitoneum, the patient's end-tidal carbon dioxide pres What kills a patient with a tension pneumothorax? Decreased resonance is noted with pleural effusion and all other lung diseases. 27 DIAPHRAGMATIC EXCURSION 1. Anatomy The diaphragm is a dome shaped, musculotendinous structure Pneumothorax with Tension. Laparoscopic diaphragmatic plication is a safe and effective operation in carefully selected patients. As a rule of thumb, the following values are worth remembering: the average excursion of the diaphragm during quiet spontaneous breathing is 20 mm (range: 2- 23 mm) and during deep breathing 60 mm (range: 40-90). This previously unreported complication of abdominal paracentesis may be due to increased diaphragmatic excursion following the procedure andshould beconsidered in patients with preexisting lung disease. The aim of this document is to promote better knowledge and more widespread use of thoracic ultrasound among respiratory physicians in Italy. At T2, subjects were classified in 2 sub- 1 2 4 3 5 6 8 7 diaphragmatic excursion difference between diaphragmatic level @ full inspiration v expiration (~5-6cm) **Done when patients have suggestive symptoms or other findings** Percuss laterally Percuss upper. We discovered that changes in LUS scores were found to be associated with an increase of diaphragmatic excursions after assessment (Spearman's r=-0.54, P<0.001). These techniques have also been applied to diagnosis of right endobronchial main stem intubation, which may be confused with a unilateral pneumothorax in some cases. diaphragmatic excursion. Diaphragmatic excursion was measured using M-mode ultrasound during normal breathing, deep breathing and with the sniff manoeuvre. gravel rash) -Pt uncooperative, confused or unconscious -OF PARTICULAR IMPORTANCE is the time from ACCIDENT UNTIL ARRIVAL diaphragmatic excursion was measured on the vertical axis of the Fig. AbstractBackground. The normal range for diaphragmatic excursion in males is: 5-7 cm . Diaphragmatic excursion: Can be evaluated via percussion. hyper-resonance (as can be simulated by percussing the inflated cheek) suggests a pneumothorax; diaphragmatic excursion - normal is 3 to 6 cm. May be abnormal with hyperinflation, atelectasis, the presence of a pleural effusion, diaphragmatic paralysis, or at times with intra-abdominal pathology. There was significant aeration loss throughout the surgery from the start of induction (P<0.001). Chemical sclerosis of the pleural space is used to prevent recurrence of spontaneous pneumothorax. Diaphragmatic excursion: Can be evaluated via percussion. 2. gravel rash) -Pt uncooperative, confused or unconscious -OF PARTICULAR IMPORTANCE is the time from ACCIDENT UNTIL ARRIVAL Objective: To determine the prevalence of diaphragmatic dysfunction diagnosed by M-mode ultrasonography (vertical excursion <10 mm or paradoxic movements) in medical intensive care unit patients and to assess the influence of diaphragmatic dysfunction on weaning outcome.. Design: Prospective, observational study. 6 Other parameters associated with diaphragmatic function including areas of atelectasis and diaphragmatic thickness was recorded. Introduction Abdominalparacentesis is awidelyusedpalliative therapy for malignant ascites and is generally The male to female ratio is about 4:1, mostly presenting in the third decade of life. If parents declined the consent. Diaphragmatic excursion and chest wall expansion increase the negative intrathoracic pressure required for inhalation. Diaphragmatic excursion and chest wall expansion in- An initial chest radiograph showed a non-outlined left hemidiaphragm, a left pneumothorax, rightward mediastinal shift and A study by Kleinman, Frey, VanDrunen, et al. lobes (anterior) Cut nails. pneumothorax as there are other lung conditions when the visceral pleura doesnt slide against the parietal pleura (e.g., apnea, pleurodesis, inflammatory adherence, over-inflation, severe be used to quantify the diaphragmatic excursion during quiet respiration (resting tidal volume), deep inspiration and sniffing. None of the enrolled patients had a negative diaphragmatic excursion. Two mechanisms have been described for pneumothorax related to endometriosis. This measures the contraction of the diaphragm. The larger diaphragmatic excursion may be compensation for the abnormal gas exchange in COPD patients, and the greater diaphragmatic motion during tidal breathing can result in respiratory fatigue in daily life. We discovered that changes in LUS scores were found to be associated with an increase of diaphragmatic excursions after assessment (Spearmans r=0.54, P<0.001). Pneumothorax: decreased expansion on affected side, hyper resonant or tympanic sounds or even absent sounds in affected areas. Decreased aeration Decreased diaphragmatic excursion Pulmonary artery thrombosis Decreased venous return to the heart. 1. Is 4-6 centimeters between full inspiration and full expiration. Tony and his wife, Janet, moved from Massachusetts to California in 1977. We describe the sono- Chest ultrasonography can be a useful diagnostic tool for respiratory physicians. Term. Hyper resonant Emphysema or Pneumothorax Auscultation Use the diaphragm, which is larger, flatter side of the chest piece to auscultate breath sounds. Chest percussion is generally performed evaluate the extent of diaphragmatic excursion and air-fluid levels. The following are features unique to tension pneumothorax: Mediastinumgets pushed to opposite side. dull; decreased diaphragmatic excursion.Chest physiotherapy techniques combine manual percussion of the chest wall and strategic positioning of the patient for mucus drainage, with cough and breathing techniques. 911 In subjects with acute dyspnea admitted to the emergency department, a diaphragmatic ultrasound excursion < 2.3 cm was associated with a need for NIV. Auscultation of the Posterior Thorax Auscultation is used to identify and discriminate between and Diaphragmatic Excursion after Pleural Sclerosis. Increased A-P chest diameter hyper resonant percussion and decreased excursion of the diaphragm: Reflects hyper inflated lungs. Diaphragm plays vital role in tidal volume generation. ie air between chest wall and lung - pneumothorax: implications of impaired diaphragmatic excursion: ie left hemidiaphragm no longer lower than the right hemidiaphragm, due to diaphragmatic paralysis (L doesn't move down with inspiration, so higher than right on CXR), LUQ mass, pleural effusion, or rarely left lower lobe lesion Patients with a history of diaphragmatic or neuromuscular disease or evidence of pneumothorax or pneumomediastinum were excluded. Discussion On assessment of diaphragmatic motion by M-mode ultrasonography, the excursion at the right hemi-diaphragm using the liver as an ultrasound window (LeMone 1210) Therefore this would be "normal" and not necessary to report to the doctor immediately. Phrenic nerve injury, with resultant impairment to diaphragmatic function,1,2 is a well-recognized and feared complication of catheter ablation. Increased resonances can be noted either due to lung distention as seen in asthma, emphysema, bullous disease or due to Pneumothorax. Would use both to evaluate concern for broken ribs, pneumothorax, or consolidation. Breath sounds are decreased when normal lung is displaced by air (emphysema or pneumothorax) or fluid (pleural effusion). to limit bloodletting! The transition point from resonant to dull percussion notes marks the approximate position of the diaphragm. . The distance between the transition point on full expiration and the transition point on full inspiration is the extent of diaphragmatic excursion (normally 3.0-cm5.5-cm ). The client with chronic bronchitis should exhale through pursed lips to prolong exhalation, keep the bronchioles from collapsing, and prevent air trapping. Furthermore, in 1995, Houston et al have reported that in healthy volunteers, the right-to-left ratio of hemidiaphragmatic excursion during deep inspiration was in the range of 0.5-1.6. Infants who have neurological insult, pneumothorax, or under muscle relaxant. Diaphragmatic excursion is the movement of the thoracic diaphragm during breathing. Materials And Methods It is performed by asking the patient to 28 TIDAL PERCUSSION 1. 3. using a 5-2 Outcome Measures. The family, now consisting of four grown children and nine grandchildren, settled in Simi Valley and has been there This previously unreported complication of abdominal paracentesis may be due to increased diaphragmatic excursion following the procedure and should be considered in patients with preexisting lung disease. Intentional pneumothorax avoids collateral damage: oablation lesion that resulted in temporary dampening of diaphragmatic excursion. and diaphragmatic excursion is evaluated. None of the enrolled patients had a negative diaphragmatic excursion. 4. It can be used to complete and widen the general objective examination also in emergency situations, at the patients bedside. Normally, the diaphragm moves caudally, but in patients with hemidiaphragmatic paralysis, the diaphragm may (paradoxically) move cranially. Contacts and Locations. Learn to perform a rapid bedside ultrasound to rule out pneumothorax, image diaphragmatic excursion, and assess for pleural effusion. While auscultation is most commonly practiced, both percussion and inspection are equally valuable techniques that can diagnose a number of lung abnormalities such as pleural effusions, emphysema, pneumonia and many others. And although in the past few years we came with If it is less than 35 cm the patient may have a pneumonia or a pneumothorax in which a chest x-ray is diagnostic for either. Compare one side to the other looking for asymmetry. The diagnosis of a pneumothorax is easily diagnosed by ultrasound when there is an absence of lung sliding as seen in this video. The main objective of this study was to assess if ultrasound-based diaphragmatic excursion (DE) is helpful with RSBI as weaning predictors. Diagnosing Pneumonia By Physical Examination | Pulmonary percussion . Therewas no signi6cant difference between diaphragmatic excursions We measured diaphragmatic excursion on both sides of subjects who had previously undergone unilateral chemical pleural sclerosis. Smaller excursions on the sclerosed side than on the contralateral side suggest that sclerosis causes a reduction in diaphragmatic excursion. No diaphragmatic excursion on affected side. diaphragm. Pneumothorax feel below the scapula on the effected side: Term. The medial surfaces of the lung are to some extent concave, providing a cradle for the heart. The note heard on percussion becomes more resonant as the diaphragm descends and lungs fill with air. A diaphragmatic abnormality was found in all eight cases. The distance between the transition point on full expiration and the transition point on full inspiration is the extent of diaphragmatic excursion (normally 3.0-cm5.5-cm ). The most commonly used weaning parameter, the rapid shallow breathing index (RSBI), gives thorough guidance on extubation timing with spontaneous breathing trials. This report presents a case of a 46-year-old woman in whom contralateral pneumothorax occurred during retroperitoneal laparoscopic donor nephrectomy without any evidence of diaphragmatic injuries. What are the abnormal findings of auscultation of pleural effusion: Definition. Setting: Twenty-eight-bed medical intensive care unit The normal range for diaphragmatic excursion in females is: 3-5 cm . 4. Diaphragm gets pushed downwardresulting in decreased diaphragmatic excursion. early signs of atelectasis are dynamic; sliding is lost, there is no lung point to be found, the lung pulse is unmasked, the diaphragm is elevated with reduced excursion a posterolateral tissue-like pattern develops over time, with the early presence of static air bronchograms, often lost as the air is In extreme cases it becomes concave upwards resulting in paradoxical movement with respiration. To test whether sclerosis restricts diaphragmatic excursion, we measured diaphragmatic excursion by ultrasonography in subjects with unilateral pleural sclerosis and compared it with diaphragmatic excursions in normal subjects, in subjects with cystic fibrosis (a diffuse bilateral lung disease), and in Ask the patient to inspire deeply. Unilateral hyperresonance suggests a large pneumothorax or possibly a large air-filled bulla in the lung. It arises from the neck a Omit the areas covered by the scapulae. (caused by emphysema or pneumothorax) When you percuss the posterior chest, when the sound changes from _____ to _____, you are at the estimated level of the diaphragm. We looked for evidence for the effectiveness of chest physiotherapy in children with The pulmonary exam is one of the most important and often practiced exam by clinicians. The sequelae from diaphragmatic rupture and subsequent herniation of intra-abdominal contents are associated with significant morbidity and mortality. Left QB 2.3 cm, Left DB=6.5 cm) and no ultrasound evidence of pneumothorax (M-mode analysis) was noted. Compared with those of normal subjects, the side-to-side differences in excursion were increased by pulmonary disease (p<.03) andadditionally by unilateral sclerosis (p<.015). Regarding diaphragmatic excursion, there was a statistically significant difference between the two groups (P <0.001). Currently, ultrasound is a favorite modality for evaluating diaphragm dysfunction [8]. First, de- An abnormally high level suggests termine the level ofdiaphragmatic dullness during quiet respiration. Hyper-resonance: (Emphysema, Asthma, Pneumothorax, Blebs) Decreased or increased resonance is abnormal. 5. The primary outcome measured was change in diaphragmatic excursion. PERCUSSION Percuss for tone. [1] Predicting successful weaning from mechanical ventilation isnt the easiest task in the world. 1. Diaphragmatic excursion 1. Atelectasis: Pneumothorax and small effusions were also diagnosed through LUS examination. diaphragmatic excursion, bilateral thickness, thickening fraction, and arterial blood gas analyses were performed at T0, T1, and T2. Which one of the following is not a common cause of pneumothorax in the ICU patient? The TF of the right diaphragm showed a significant increase from the initial to the follow-up values (80.1 104.9 mm vs. 159.5 224.6 mm, p = 0.011); however, the diaphragmatic excursion did not vary significantly between the initial and follow-up values (22 6 mm vs 23 12 mm). The main objective of the study was to compare ultrasound-based diaphragmatic excursion (DE) with RSBI as weaning predictors. 2 and diaphragmatic excursion (P=0.022). Traumatic Pneumothorax Detailed History of Presenting Illness (HPI) As relevant to a motor vehicle accident: -Bruised chest -Painful area of ribs -Shortness of breath -Lacerations consistent with road trauma (eg. Chemical sclerosis of the pleural space is used to prevent recurrence of spontaneous pneumothorax. Learn about ventilation of COVID-19 patients with the latest research on ventilation of coronavirus patients. diaphragmatic excursion (DE), and diaphragmatic thickening fraction (DTF) were measured in the zone of apposition. 911 In subjects with acute dyspnea admitted to the emergency department, a diaphragmatic ultrasound excursion < 2.3 cm was associated with a need for NIV. Never used diaphragmatic excursion, but used to work for a SP that used tactile fremitus and chest percussion routinely- SP was hearing impaired and couldnt used a stethoscope, but it was impressive his ability to use tactile sensation to complete a lung exam. pneumothorax. To test whether sclerosis restricts diaphragmatic excursion, we measured diaphragmatic excursion by ultrasonography in subjects with unilateral pleural sclerosis and compared it with diaphragmatic excursions in normal subjects, in subjects with cystic fibrosis (a diffuse bilateral lung Diaphragmatic excursion is decreased on the affected side in pleural effusion and in pneumothorax . Diaphragmatic excursion decreased in the operated side by 56% [36 to 72%] in the thoracotomy group and by 43% [23 to 58%] in the video-assisted thoracoscopic surgery group (P = 0.033 for comparison between groups) 24 h postoperatively, as compared to preoperatively . depressed in case of emphysema or pneumothorax raised in case of lung fibrosis, collapsed lung, consolidation, ascites, massive abdominal tumor or pleural effusion. 4. Normal values for diaphragmatic excursion vary in the general population (Gerscovich et al. Percussion Notes and Their Meaning Flat or Dull ----Pleural Effusion or Lobar Pneumonia Resonant---Normal Healthy Lung or Bronchitis Hyperresonant Emphysema or Pneumothorax 39. Diaphragmatic excursion is the movement of the thoracic diaphragm during breathing. Normal diaphragmatic excursion should be 35 cm, but can be increased in well-conditioned persons to 78 cm. This measures the contraction of the diaphragm. It is performed by asking the patient to exhale and hold it. Because most of our patients also had generalized underlying lung disease (cystic fibrosis), and because lung disease itself might alter diaphragmatic excursion on one side, we also examined relative diaphragmatic excursion in a comparable group of patients who had not had a pneumothorax or undergone either chemical or surgical treatment. Muffled and softer note; Sign of fluid inside the thoracic cavity: pneumonia, pleural effusion; Assess diaphragmatic movement. Auscultate from side to side and top to bottom using the pattern shown in the illustration. decrease in preoperative pulmonary function, or abnormality in preoperative chest radiography data (pleural effusion, pneumothorax, or hemidiaphragm elevation) Diaphragmatic excursion (DE) was first explored in roentgenography in 1969 and ultrasound (US) in 1975 ().This technique aids human medicine in the evaluation of diaphragmatic function, the major muscle function in respiration (1, 2).Initially, DE was used to detect the respiratory problems that induced dyspnea ().In the last few years, studies have shown that DE 5 of 10 near the apex of the diaphragmatic excursion during deep expiration on each side Excursion is 3 to 5 cm (1.5 to 2 in) bilaterally in women and 5-6 cm (2 to 3 in) in men. M-mode was performed in conjugation with conventional B-mode ultrasound. has shown that total diaphragmatic excursion is significantly greater during normal spontaneous During expiration, the same measurements can be performed between the beginning and the end of the expiratory slope giving the diaphragm expiratory amplitude, the expiratory time, and the diaphragm expiratory velocity. There was significant aeration loss throughout the surgery from the start of induction (P<0.001). [1] Predicting successful weaning from mechanical ventilation isnt the easiest task in the world. Virtual training sessions may also be helpful to those new to the technique. Diaphragm Excursion-Time Index: A new parameter using ultrasonography to predict extubation outcome, by Atul Palka et al. Brachial plexus is a complex network of nerves supplying the whole upper limb, with both motor and sensory supply. Diaphragmatic excursion is decreased in obese clients as a result of fatty tissue on the diaphragm interfering with mechanical movement. Pneumothorax and small effusions were also diagnosed through LUS examination. Diaphragmatic ultrasound excursion and thickness have been shown to be variously affected in subjects admitted to the emergency department with AHRF. ly including the use of sonography to evaluate lung expansion and diaphragmatic excursion. 2001). Extubation failure increases mortality, infections, ICU length of stay and costs [2,3]. On two occasions abdominal paracentesis was followed within 72 hours by pneumothorax. Ausculation. deviated: contralateral pneumothorax/pleural effusion, ipsilateral atelectasis decreased mobility: mediastinal fixation (neoplasm, TB) Percussion dull: pneumonia, pleural effusion, atelectasis, hemothorax, empyema, tumour hyperresonant: emphysema, pneumothorax, asthma diaphragmatic excursion (normal diaphragmatic movement 4-5 cm Inspiratory crackles (decompensated congestive heart failure) Expiratory wheezes (asthma, emphysema) Stridor and other upper airway sounds; Bronchial vs. vesicular breath sounds The level of dullness (diaphragmatic excursion) should go down 3-5cm symmetrically. To test whether sclerosis restricts diaphragmatic excursion, we measured diaphragmatic excursion by ultrasonography in subjects with unilateral pleural sclerosis and compared it with diaphragmatic excursions in normal subjects, in Abnormally high transition points on one side may be seen in unilateral pleural effusion and unilateral diaphragmatic paralysis. Ultrasound B-mode using 7.5MHz probe in the zone of apposition. Exhalation should be longer than inhalation to prevent collapse of the bronchioles. Diaphragmatic excursion and chest wall expansion increase the negative intrathoracic pressure required for inhalation. 2. Post-surgery diaphragmatic excursion was measured in QB and DB (Right QB=1.95 cm, Right DB=6.05 cm. The maximum inspiratory pressure (PImax) was also recorded. Diaphragmatic atrophy is also noted with prolonged paralysis, depicted as a diaphragmatic thickness below 0.2 cm at end expiration. In the majority of cases employing POC we are looking at ultrasound artifacts. Feasibility was estimated by considering the number of subjects whose diaphragmatic function could be evaluated at each time point. Decreased breath sounds with hyper-resonance is the most important physical finding for emphysema. C: Attempted phrenic nerve displacement through percutaneous subxyphoid was without pneumothorax, with intact bilateral diaphragm function. 28. Decreased or asymmetric diaphragmatic excursion may indicate paralysis or emphysema. On M-mode, the Decreased diaphragmatic excursion, prolonged expiration are common to all of the chronic obstructive lung diseases. The tracheobronchial tree is a tubular system that provides a pathway along which air is Diaphragmatic excursion 1. Pleural Effusion: decreased expansion of affected side, trachea & heart shifted away from affected side, dullness or flatness or absent breath sounds. Post hoc analysis revealed that the diaphragmatic excursion was significantly higher in Group BC compared to Group CON at first, second and third minute post-step test. Find the level of the diaphragmatic dullness on both sides. Diaphragmatic excursion and extubation success. pneumothorax) Increased fremitus (associated with consolidated lung tissue, as in pneumonia). Barotrauma All patients were male, and the mean age was 79.8 years. Normal inspiratory diaphragmatic movement is caudal, with the corresponding M mode trace being upwards as the diaphragm moves toward the probe, the expiratory trace is downwards as the diaphragm moves away from the probe [9].
