Answer to Question 1

ANS: B
Initial ventilator settings include choice of mode, tidal volume, rate, FiO2, and PEEP. The respir-atory therapist must set the trigger level, inspiratory flow or time, alarms and limits, backup ven-tilation, and humidification.

Answer to Question 2

ANS: B
Primary goals of mechanical ventilation are: adequate alveolar ventilation (VA), maintaining tissue oxygenation, FiO2, PEEP, and MAP, restoring acid-base balance, reducing WOB and myocardial work, providing PEEP/CPAP to recruit lung, lung protective strategy: Small VT and appropriate PEEP levels and maintaining Pplat less than 30 cm H2O.
