Overview
Respiratory failure may be classified into several subtypes as follows; Type I, Type II, Type III, Type IV.
Classification
The classification of respiratory failure is as follows:[1]
| Respiratory Failure | |||||||||||||||||||||||||||||||
| Type I | Type II | Type III | Type IV | ||||||||||||||||||||||||||||
| Hypoxemic | Hypercapnic | Peri-operative | Shock | ||||||||||||||||||||||||||||
Classification based on A-a gradient
Respiratory failure patients may have a normal or increased A-a gradient depending upon the etiology of the respiratory failure. The following table outlines the major characteristics:
| Respiratory Failure-decreased SaO2 | |||||||||||||||||||||||||||||||||||||||||||||
| Normal A-a gradient | Increased A-a gradient | ||||||||||||||||||||||||||||||||||||||||||||
| Normal PaCO2 | Increased PaCO2 | Hypoxemia does not correct with 100% O2 | Hypoxemia corrects with 100% O2 | ||||||||||||||||||||||||||||||||||||||||||
