Atelectasis laboratory findings

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Sudarshana Datta, MD [2]

Overview

Patients with atelectasis have hypoxemia with low levels of PaO2 and normal/low PaCO2 levels on ABG analysis. Raised peak and end-inspiratory plateau pressures due to decreased lung compliance are also present in these patients.

Laboratory Findings

Laboratory findings consistent with the diagnosis of atelectasis include:^[1]
- Hypoxemia with low levels of PaO2 on aterial blood gas analysis
- Normal/low PaCO2 levels on arterial blood gas analysis
- Raised peak and end-inspiratory plateau pressures due to decreased lung compliance
