Question Answer
Spontaneous ventilation in adults; not enough CO2 for plateau phase could be because the
ET tube is too small.
forgot to inflate cuff or it's a cuffless ET tube
Cardiogenic Oscillations seen during low frequency vnetilation or with small px where the heart vibrates against lungs; it's also normal in athletic/deep chested dogs
Esophageal Intubation resulting in a few abnormal capnograms w/ relatively normal CO2 numerical values- notice the baseline is disjointed
Esophageal intubation or malfunctioning capnogram- this one was listed as
*extra important*
Hyperventilation gradually results in lower ETCO2- Decreased CO then check the BP, check the HR and then intervene; Hyperventilation may be caused by
Hypothermia,
PULMONARY EMBOLISM, Decreased metabolism- THIS IS IMPORTANT ONE
Hypoventilation results in gradually increasing CO2 values w/ normal baseline; could be caused by
Increasing CO,
Issue w/ heart or lungs,
Increased cellular
metabolism due to
Hyperthermia or
Sepsis
Warming up CO2 analyzer is necessary before it begins recording waveforms
Re-breathing of CO2 due to exhausted absorbent, incompetent exp valve,
insuffx FGF,
Bain intubx problem,
intertube tear,
Didn't turn on O2
Be familiar with it
bronchospasm,
COPD,
Emphysema,
Obstructed endotracheal tube due to mucous plug, tumor, kink, asthma
Be familiar with it
Abnormal baseline means it's a mechanical issue but if anything else abnormal then it's a px issue
