Official title

Carbon Dioxide (CO2) Clearance From Various Face Masks in Normal Volunteers at Various Level of Expiratory Positive Airway Pressure (EPAP) When Using a Non-Invasive Positive Pressure Ventilation (NIPPV)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This study will be a randomized crossover trial that will be conducted at Rush University. The study will be conducted with 20 healthy volunteers who will be placed on ICU ventilator operating in the NIPPV mode. All subjects will perform 15 minutes of breathing on NIPPV on each mask of the 4 different masks (2 oronasal and 2 full face masks) that are randomly selected. Breathing through each mask will be followed by a 5- minute wash out period between masks. End tidal Carbon Dioxide (EtCO2) will be sampled nasal/oral. Different levels of EPAP will be set and CO2 clearance will be monitored. Additionally, subjective mask comfort will be assessed via visual analog scale (VAS) with 1 referring to least comfortable and 5 being the most comfortable.
