Patients with OHS are efficiently managed with long term home-based nocturnal noninvasive positive pressure ventilation (NIPPV). Several NIPPV devices offer the feature of automatically adjusting pressure support (and/or respiratory back-up rate) on the basis of a pre-determined "ideal tidal volume" or "ideal ventilation". However algorithms used to achieve these ideal targets are different among different commercialized devices and the relative efficacy from an algorithm compared to another remains unknown. The main objective is this study is to compare two commercialized NIPPV that have this option

Condition Intervention
Obesity Hypoventilation Syndrome Device: IVAPS Device: AVAPS

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Comparison of Two Noninvasive Positive Pressure Ventilation Devices Using Target Volume Modes in Obesity Hypoventilation Syndrome (OHS): A Pilot Randomized Crossover Controlled Trial

Further study details as provided by AGIR à Dom:

Primary Outcome Measures:
  • Mean Nocturnal transcutaneous CO2 pressure (Mean nocturnal PtCO2) [ Time Frame: 1 night ]
    transcutaneous CO2 pressure is measured overnight. It is a reliable estimation of arterial PaCO2 to monitor nocturnal ventilation in adults with chronic respiratory failure.

Secondary Outcome Measures:
  • Mean transcutaneous CO2 pressure during REM Sleep [ Time Frame: 1 Night ]
  • Mean nocturnal SpO2 [ Time Frame: 1 night ]
  • Awake arterial PaCO2 after 1 hour of NIPPV withdrawal [ Time Frame: After 1 night ]
  • Micro-arousals/hour of sleep [ Time Frame: 1 night ]
  • Sleep Quality assess by Visual analogic scale (100mm) [ Time Frame: 1 night ]
  • Respiratory residual events detected by NIPPV built-in softwares [ Time Frame: 1 Night ]
