is nitrous oxide used alone
1 contraindication to use of nitrous oxide
resp disease
diffusion hypoxia=
If nitrous oxide left in lungs will displace oxygen. Run O2 for a few min after turning an gas off
how often should anesthetized patient be checked
every 5 min
1 clinical sign seen in patient if o2 absorber exhausted-REBREATHER ONLY
