CB41.20 Respiratory failure, unspecified, Type I

International Classification of Diseases for Mortality and Morbidity Statistics, 11th Revision, v2025-01

This is when the PaCO2 may be normal or low. It is typically caused by a ventilation/perfusion (V/Q) mismatch; the volume of air flowing in and out of the lungs is not matched with the flow of blood to the lungs. The basic defect in type 1 respiratory failure is failure of oxygenation.
