A valved gas collection assembly for high-flow CPAP systems produced no significant differences in flow and pressure patterns compared to a valveless system at pressures of 5 to 12 cm H2O.
Does a valved gas collection assembly for high-flow CPAP systems alter volume, pressure, and flow patterns compared to a valveless system in volunteer subjects?
A newly developed valved gas collection assembly for high-flow CPAP systems does not significantly alter flow or pressure patterns, enabling metabolic measurements.
Absolute Event Rate: 0% vs 0%
We have developed a valved gas collection assembly for high-flow CPAP systems that permits the isolation of expired gases for the analysis and computation of oxygen uptake and carbon dioxide production. Using volunteer subjects we compared the valved assembly with a high-flow valveless CPAP system for volume, pressure, and flow differences at end-expiratory pressure levels of 5, 7, 10, and 12 cm H 2 O and found that the valve produced no significant differences in the flow/pressure pattern.
