Capnography Flashcard Deck - 10 Cards

Flashcard 1: A notch or dip in the alveolar plateau (Phase III) of a capnography waveform represents:_____

Answer: Curare clefts

Extra: Curare clefts appear as a notch or dip in the alveolar plateau (Phase III) of the capnogram. This finding indicates that the patient is making spontaneous respiratory efforts during mechanical ventilation, typically when neuromuscular blockade is wearing off or is insufficient.

Flashcard 2: On capnography, a progressive increase in the EtCO2 plateau height (while maintaining a normal waveform shape) represents: _____

Answer: Hypoventilation

Extra: Hypoventilation results in CO2 retention, which manifests on capnography as a progressive increase in the height of the EtCO2 plateau. Conversely, hyperventilation leads to a decrease in EtCO2 levels.

Flashcard 3: Which anesthetic equipment malfunction is characterized by a capnography waveform showing an elevated baseline and a prolonged Phase III (alveolar plateau)?

Answer: Expiratory valve malfunction

Extra: Incompetence of either the inspiratory or expiratory valve results in rebreathing of CO2, manifested as an **elevated baseline** (the CO2 level does not return to zero during inspiration). An **expiratory valve malfunction** specifically results in a prolonged Phase III (alveolar plateau) and an elevated baseline because exhaled gas is drawn back from the expiratory limb during inspiration.

Flashcard 4: Which capnographic feature indicates spontaneous breathing efforts in a patient under mechanical ventilation?

Answer: Curare cleft (indicating spontaneous breathing efforts)

Flashcard 5: The capnographic waveform shows an elevated inspiratory baseline, which depicts _____.

Answer: rebreathing

Flashcard 6: Phase _____ of normal capnography is the plateau, corresponding to the pCO2 in the alveolar compartment

Answer: III

Flashcard 7: A capnography waveform with an elevated baseline (where CO2 does not return to zero during inspiration) represents:_____

Answer: **Exhausted CO2 absorber** (leading to rebreathing)

Flashcard 8: Phase _____ of normal capnography is exhalation of dead space gas

Answer: I

Flashcard 9: The following capnography waveform represents: _____

Answer: hypoventilation

Flashcard 10: Mapleson _____ circuit is also referred to as Waters' circuit

Answer: C
