Abstract:
A 22-year-old man on postoperative day 1 after open reduction with internal fixation of a distal fibula fracture presented with hemoptysis and increased oxygen demand. X-ray and contrast-enhanced computed tomography revealed bilateral patchy opacities and mediastinal emphysema. After bronchoscopy and bronchoalveolar lavage, a diagnosis of alveolar hemorrhage was made. The medical history revealed regular abuse of marihuana and cocaine.

Endotracheal Tube Extubation
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals.
Endotracheal Intubation II: Nursing Management
1. Nursing Care of Patients Before Intubation
Before the endotracheal intubation procedure, nurses play an essential role in ensuring the process goes smoothly. The nurses must be familiar with intubation...
Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
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...
