As Nоаh wоre the PMV, his ventilаtоr settings were reduced over the next two weeks to BiPAP settings (а spontaneous, weaning mode). Once Noah had been comfortable on the BiPAP settings, it was decided to trial the tracheostomy mask. The RT removed him from the vent and placed him on a room air tracheostomy mask with humidification. Within one minute, Noah’s SpO2 dropped from 98 to 87% and he struggled to breathe. After the RT bagged him and returned his SpO2 to baseline, he was placed back on the ventilator. After several minutes on the ventilator, Noah calmed down and was able to catch his breath. He stated that the feeling was so different off the ventilator, and he was scared because he could not talk. When he finally became comfortable with the idea being off the ventilator again (still on BiPAP settings), we presented him with a new plan. We would remove him from the ventilator and place him on his PMV immediately, skipping the tracheostomy mask. We explained the reasons to him. First, being the most important to him was that he would be able to talk, which would assist with being less anxious. The second main reason to place the PMV immediately was so that his lungs did not lose pressure. How does the PMV keep Noah's lungs from loosing pressure?
