Anesthetic Equipment and Monitoring — Flashcards

Flashcard 61: Mapleson _____ circuit is also referred to as Water's to and fro

Answer: C

Flashcard 62: The most effective circuit for anesthesia under controlled breathing is Mapleson _____

Answer: D (Bain circuit)

Extra: Efficiency of Mapleson circuits: - **Controlled ventilation**: D > E > F > B > C > A - **Spontaneous ventilation**: A > D > E > C > B

Flashcard 63: Phase _____ of the normal capnograph is also known as inspiratory downstroke

Answer: 0

Flashcard 64: Rhythmic ripples on the expiratory plateau of a capnogram that coincide with the heart rate represent: _____

Answer: Cardiac oscillations

Extra: Cardiac oscillations are rhythmic ripples seen on the capnography waveform (usually in the expiratory plateau or descending limb) that coincide with the patient's heart rate. They are caused by the mechanical action of the heart beating against the lungs, causing small volumes of gas to move. They are more common in pediatric patients and those with slow respiratory rates.
