Balloon catheter re-expansion of atelectatic lung
1Intensive Care Unit, Winnipeg General Hospital, Manitoba, Canada.
Abstract:
Selective re-inflation of the lung with lobar atelectasis was carried out in four patients who were receiving mechanical ventilation. The increased pressure and volume were delivered mainly to the atelectatic lung by momentary obstruction of mainstem bronchus of the uninvolved lung with a balloon-tipped catheter. Blood gases and chest x-rays following the procedure showed improvement in oxygenation with prompt re-expansion of the atelectatic lung. The described procedure is recommended in atelectasis involving major portions of the lung with severe hypoxemia not responding to aggressive conventional treatment.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
Endoscopic Studies II: Thoracocentesis
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
