ETC02 Flashcards
What does a ETC02 under 35mmhg mean
Hyperventilation/Hypocapnia
What does a ETC02 over 45mmhg means
Hypoventilation/Hypercapnia
What is normal ETC02
35-45mmhg
What is phase 1 for ETC02 waveform capnogram
Inspiratory baseline
What is phase 2 for ETC02 waveform capnogram
Expiratory upstroke
What is phase 3 for ETC02 waveform capnogram
Expiratory plateau
What is D or the right upper corner for ETC02 waveform capnogram
End expiration
What is phase 4 for ETC02 waveform capnogram
Expiratory downstroke
What is the final part of ETC02 waveform capnogram
Phasel or back to inspiratory baseline
What does a sudden loss of waveform indicate for ETC02
ET tube disconnect, dislodged, or kinked
Loss of circulation
What does a decreasing ETC02 wave form indicate
ET tube cuff leak
ET tube in the hypopharynx
Partial obstruction
What ETC02 should we maintain during CPR
10mmhg
What does a sudden increase in ETC02 wave form indicate
ROSC
What does a “shark fin” ETC02 wave form indicate
Bronchospasm (COPD, asthma)
What does a long phase 2 ETC02 wave form indicate
Hypoventilation
What does a DECREASED ETC02 wave form indicate
Apnea or sedation (it looks like the wave form is all over the place)
What can cause hypoventilation (high ETC02)
OD
Sedation
Intoxication
Head trauma
Stroke
Tiring CHF
Postictal seizure states
Fever
Sepsis
SOB
What are some causes of hyperventilation (low ETC02)
Anxiety
Broncospasm
Pulmonary embolism
Cardiac arrest
Hypotension
Decreased cardiac output
Cold
