Respiratory Failure and Assisted Respiration

Abstract

Respiratory failure is the inability to exchange oxygen and carbon dioxide with the inhaled gas in the lungs. This can be improved by providing mechanical assistance to the ventilation of the lungs.

Keywords: respiratory failure; sleep and respiration; assisted ventilation; tracheostomy ventilation; nasal ventilation
