Impact of circuit configuration on the mechanical performance of CPAP therapy devices: an experimental study.

ABSTRACT:

Introduction

CPAP therapy treats various respiratory disorders. The overall performance of therapy delivery can be affected by the adopted circuit configuration. Recently, parallel to the canonical open configuration (OC), closed configurations (CC) have been proposed with potential advantages in terms of oxygen consumption, noise, airway dryness and contamination. However, the mechanical performance of CPAP devices in CC has been marginally investigated. The aim of this study is to clarify whether CPAP therapy delivered in CC configuration retains mechanical performances equivalent to that achieved in the canonical OC stipulated by the manufacturers.

Methods

OCs and CCs implemented on seven different ventilation devices, classified as flowmeter, obstructive sleep apnoea dev
