Following these function tests a special type of Chest CT scan or a bronchoscopy will be ordered. The results of the scan and bronchoscopy [ 9 ] will display the status of the condition. A mild case of tracheobronchomalacia would be if the patient's trachea condenses 50% of its normal space when exhaling.
Dynamic compression of the airways results when intrapleural pressure equals or exceeds alveolar pressure, which causes dynamic collapsing of the lung airways. It is termed dynamic given the transpulmonary pressure (alveolar pressure − intrapleural pressure) varies based on factors including lung volume, compliance, resistance, existing pathologies, etc. [1]
Furthermore, when a patient lays supine for a CT scan, the posterior lungs are in a dependent position, causing partial collapse of the posterior alveoli. This leads to an increase in density of the tissue, resulting increased attenuation and a possible ground-glass appearance on CT. [3]
Chest Imaging: either chest x-ray or CT scan, must show bilateral opacities that cannot be fully explained by other conditions such as effusion, lung/lobar collapse, or lung nodules. Origin of Edema: respiratory failure that cannot be fully explained by cardiac failure or fluid overload, this needs objective assessment such as an echocardiogram .
Heavy rains that swept across Pakistan have left at least 29 people dead and 50 others injured, collapsed houses and triggered landslides that blocked roads, particularly in the northwest ...
Bronchoalveolar lavage (BAL), also known as bronchoalveolar washing, is a diagnostic method of the lower respiratory system in which a bronchoscope is passed through the mouth or nose into an appropriate airway in the lungs, with a measured amount of fluid introduced and then collected for examination.
Chronic obstructive pulmonary disease (COPD) is a type of progressive lung disease characterized by chronic respiratory symptoms and airflow limitation. [8] GOLD 2024 defined COPD as a heterogeneous lung condition characterized by chronic respiratory symptoms (dyspnea or shortness of breath, cough, sputum production or exacerbations) due to abnormalities of the airways (bronchitis ...
With acute upper airway obstruction, respiratory distress can rapidly lead to respiratory failure without appropriate management [2] necessitating urgent and comprehensive assessment of ABCs (airway, breathing, and circulation). [1] Imaging studies, including x-rays and CT scans, can aid diagnosis and quickly assess the obstruction's extent. [2]
