Appropriate studies revealed extremely low respiratory tidal volumes of 200 ml and values for alveolar minute ventilation approximately one third of normal. Marked carbon dioxide retention was present.

A PaO2/FIO2 ratio is an index to characterize the acute respiratory distress syndrome (ARDS), which involves severe hypoxemia (insufficient oxygen content in blood). PaO2 is the partial pressure of oxygen in arterial blood. It’s usually measured in millimeters of mercury (mmHg or Torr) by the test called arterial blood gas (ABG) analysis. PaO2 of 75 to 100 mmHg is considered normal.
