What are the 3 types of Atelectasis?
- Gas Absorption
- Lobar
- Compression
Gas absorption atelectasis can occur when mucus plugs block _________________ to selected regions of lungs, which causes ______ mismatch
ventilation;
V/q
Lobar atelectaisis happens when ________________ is compromised in a……..
ventilation;

IPPB tx last about (range)
15- 20 minutes
IS is ____% pt effort
100%
IPPB can be modified to adjust the….
pressure that the pt is getting
Pts do not have to be cooperative while doing IPPB, as long as a pt can
take a deep breath it can be done
