Interpret the significance of the arrow shown on breath C present on the pressure-time scalar
A. an inspiratory pause
B. an expiratory pause
C. alveolar overdistention
D. flow-cycling criterion
ANS: B
A. Incorrect response: See explanation B.
B. Correct response: The arrow on the pressure-time scalar under the breath labeled "C," shown in rationale #13, indicates that an expiratory hold was applied at the time the third breath in the sequence of the three shown. Performing an expiratory hold at this point in the ventilatory cycle enables auto-Peep to equilibrate with the circuit pressure and be measured.
