DiapHRaGM: A mnemonic to describe the work of breathing in patients with respiratory failure.

ABSTRACT:

Background

The assessment of the work of breathing in the definitions of respiratory failure is vague and variable.

Objective

Identify a parsimonious set of signs to describe the work of breathing in hypoxemic, acutely ill patients.

Methods

We examined consecutive medical ICU patients receiving oxygen with a mask, non-invasive ventilation, or T-piece. A physician inspected each patient for 10 seconds, rated the level of respiratory distress, and then examined the patient for vital signs and 17 other physical signs. We used the rating of distress as a surrogate for measuring the work of breathing, constructed three multivariate models to identify the one with the smallest number of signs and largest explained variance, and validated it with bootstrap analysis.
