Respiratory failure

Respiratory failure is a serious disorder of lung ventilation and / or ventilation caused by various reasons, which prevents effective gas exchange, leading to hypoxia with (or without) carbon dioxide retention, which causes a series of physiological functions And clinical disorders of metabolic disorders. At sea level atmospheric pressure, breathing room air under resting conditions, excluding intracardiac anatomic shunt and primary decrease in cardiac output, etc., the arterial oxygen pressure (PaO2) is lower than 8kPa (60mmHg), or accompanied by Partial carbon dioxide pressure (PaCO2) higher than 6.65kPa (50mmHg) is respiratory failure (referred to as respiratory failure). It is a state of dysfunction, not a disease, which can be caused by a lung disease or a complication of various diseases. Must be handled in a timely manner, otherwise it is easy to be life threatening.
