Exercise end-tidal CO2 predicts central sleep apnea in patients with heart failure.

Chest - 1 Jun 2015

Cundrle Ivan, Somers Virend K, Johnson Bruce D, Scott Christopher G, Olson Lyle J

Abstract excerpt

BACKGROUND: Increased CO2 chemosensitivity and augmented exercise ventilation are characteristic of patients with heart failure (HF) with central sleep apnea (CSA). The aim of this study was to test the hypothesis that decreased end-tidal CO2 by cardiopulmonary exercise testing predicts CSA in pa...
