What is respiratory failure according to blood gas analysis criteria

Arterial blood gas analysis criteria for respiratory failure mainly depend on changes in PaO2 and PaCO2, and can be divided into type I and type II, characterized by PaO250 mmHg, which are associated with pulmonary ventilation or alveolar ventilation dysfunction.

Arterial blood gas analysis criteria for respiratory failure mainly depend on changes in arterial partial pressure of oxygen (PaO2) and partial pressure of carbon dioxide (PaCO2). According to these criteria, respiratory failure can be divided into type I and type II.

Type I respiratory failure is characterized by PaO2.
