Acetazolamide and inhaled carbon dioxide reduce periodic breathing during exercise in patients with chronic heart failure.
BACKGROUND Periodic breathing (PB) during sleep and exercise in heart failure (HF) is related to respiratory acid-base status, CO2 chemosensitivity, and temporal dynamics of CO2 and O2 sensing. We studied inhaled CO2 and acetazolamide to alter these factors and reduce PB. METHODS AND RESULTS We measured expired and arterial gases and PB amplitude and duration in 20 HF patients during exercise...
متن کاملPeriodic breathing in heart failure: bridging the gap between the sleep laboratory and the exercise laboratory.
In the 19th century, Cheyne 1 and Stokes2 described a pattern of periodic breathing in patients with heart failure, but over the past few decades, particular attention has been given to the occurrence of periodic breathing during sleep.3,4 Central sleep apnea, also referred to as CheyneStokes respiration, is an abnormal periodic breathing pattern in which central apneas and hypopneas alternate ...

متن کاملThe resistive and elastic work of breathing during exercise in patients with chronic heart failure.
Patients with heart failure (HF) display numerous derangements in ventilatory function, which together serve to increase the work of breathing (W(b)) during exercise. However, the extent to which the resistive and elastic properties of the respiratory system contribute to the higher W(b) in these patients is unknown. We quantified the resistive and elastic W(b) in patients with stable HF (n = 9...
