Continuous positive airway pressure setups evaluated at simulated exercise conditions

Intraocular Pressure during Continuous Positive Airway Pressure

Nasal continuous positive airway pressure devices do not maintain the set pressure dynamically when tested under simulated clinical conditions.

STUDY OBJECTIVES Nasal continuous positive airway pressure (CPAP) is standard therapy for obstructive sleep apnea syndrome. The effective nasal mask pressure may be adversely affected by factors that increase system resistance (eg, long tubing and/or water condensation) and by dynamic variables (breathing frequency [f] and tidal volume [VT]). The present study was conducted in order to assess t...

Continuous positive airway pressure therapy: new generations.

Continuous positive airway pressure (CPAP) is the treatment of choice for obstructive sleep apnoea syndrome (OSAS). However, CPAP is not tolerated by all patients with OSAS and alternative modes of pressure delivery have been developed to overcome pressure intolerance, thereby improving patient comfort and adherence. Auto-adjustable positive airway pressure (APAP) devices may be utilised for th...

Predicting effective continuous positive airway pressure.

PURPOSE The purpose of this study was to compare the pressure required to abolish apneas as predicted from a previously derived algorithm (Ppred) with the true effective pressure (Peff) determined during a continuous positive airway pressure (CPAP) titration study. SETTING Sleep clinic of a university hospital. METHODS We prospectively studied 329 patients with sleep apnea undergoing CPAP t...
