Objectives:
Alveolar-pleural fistulas causing persistent air leaks are conditions associated with prolonged hospital courses, high morbidity, and possibly increased mortality. Intrabronchial valves serve as a noninvasive therapeutic option for the closure of alveolar-pleural fistulas.
Methods:
The present review describes a brief history of, and indications for, the placement of intrabronchial valves in patients with persistent air leaks. The essential steps necessary for placement are air leak isolation, airway sizing, and valve deployment. Additionally, the indications and methods for intrabronchial valve removal, along with the potential complications from intrabronchial valve placement, are described.
Conclusions:
The increased use of intrabronchial valves in the treatment of persistent air leaks requires bronchoscopists and clinicians to understand the procedural steps and techniques necessary for intrabronchial valve placement.

Clinical Manifestations:
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,...

Inhaled Medications
Pneumonia V: Nursing management and Prevention
The nurse must practice strict medical asepsis and adhere to infection control guidelines to minimize healthcare-associated infections.
Enhance airway patency
Position the patient correctly to facilitate drainage of the affected lung segments. Manual or mechanical percussion and vibration can also be employed.
