Summary

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.

Conditions

  • CO2 Clearance
  • Mask Comfort
  • Rebreathing Exhaled Gas

Interventions

DEVICE

Evaluated 4 masks used for NIV with mechanical ventilators

Order of the masks (BiTrac MaxShield™ with standard elbow, BiTrac™ Full Face with standard elbow, Respironics PerforMax with standard elbow, and Respironics AF531 with standard elbow) were randomly chosen. Investigators randomly assigned all masks for paper raffling from container. All subjects performed 20 minutes on each mask followed by 5 minutes wash out interval between masks. EPAP levels will be 0, 2, 4, \& 5 (5 minutes for each level) while IPAP remains at 5 higher than EPAP. FiCO2 and EtCO2 were collected at 4:00, 4:30 and 5:00 minute mark for each EPAP level. Also, subjective mask comfort was assessed via visual analog scale (VAS) with 1 referring to least comfortable and 5 being the most comfortable after 5 each EPAP setting.
