A home care patient with kyphoscoliosis requires intermittent positive pressure breathing (IPPB) treatments twice per day with O2
A local charitable organization has given the family a pneumatically powered IPPB device for this purpose. Which of the following gas sources would you recommend to drive this device?
1. Liquid O2 reservoir
2. O2 concentrator
3. Compressed gas cylinder
a. 1 and 2 only
b. 2 and 3 only
c. 3 only
d. 1, 2, and 3
ANS: C
Because both concentrators and personal liquid O2 systems operate at low pressures, they cannot be used to drive equipment needing 50 psi, such as pneumatically powered ventilators and large-volume jet nebulizers.
