Capnography Flashcards
Capnography readings are _________ less than paCO2
4-5 mm Hg
> 40 mm Hg capnography reading
hypoventilation
<32 mm hg capnography reading
hyperventilation
Biggest advantage of capnography
evaluates ventilation (breathing)
Name three clinical situations where capnography would be useful in evaluating ventilation
- Anesthesia
- PPV positive pressure ventilation
- CPR
Respiratory depression is common during anesthesia making it important to monitor for __________ _____ via capnography to prevent ___________
Increased CO2
Acidosis
Capnography is an effective perfusion indicator during CPR. CPR is effective when CO2 ____________
Increases
Normal shape of a capnograph
ascend plateau descend
Capnograph x axis and y axis
X: Respiratory rate frequency
Y: CO2 concentration
