AEMT NREMT Practice Questions with 100%
Correct Answers
End tidal co2
measure of concentration of co2 at the end of the exhalation phase
capnometry
device that provides a digital numeric reading of the end tidal co2
Capnography
provides both a numeric reading and visual graph of the end tidal co2 levels for each breath
normal range for etco2
35-45mmhg
what is the use for end tidal
confirm placement for advanced airways, assess ventalatory status ie hypo or
hyperventilation
what do you want the end tidal to be at during a cardiac arrest
10mmhg or more
what does capnography provide estimates of
carbon dioxide production, alveolar ventilation, arterial carbon dioxide ventilation
if etco2 declines during cardiac arrest this means
chest compressions are not fast or deep enough
, during cardiac arrest if you get a sudden increase of etco2 levels what does this usually
indicate
rosc was achieved
what does the height of the waveform indicate
amount of co2 inhaled
what does the length of waveform indicate
time of breath
what is acidosis
buildup of excess acid in the blood, ph is more acidic than normal, lack of bicarbonate
present
what is alkalosis
buildup of excess in the blood or bpdy tissue, ph is less acidic than normal, excess
bicarbonate present
what is the normal ph balance
7.35 7.45
what is the normal partial pressure co2 (paco2)
35-45 mmHg
what is the normal hc03 (bicarbonate)
22-26
respiratory acidosis is caused by
