Please note: exam questions are subject to change.

1. All of the following are characteristics of volume target ventilation, EXCEPT: Guaranteed volume Delivers the volume at lowest PIP possible Volume being delivered can be restricted by what the high/mac PIP alarm is set at Decreased ventilator-patient synchrony with accelerating flow pattern
2. What is the primary characteristic of assist control ventilation mode? The patient can initiate additional breaths over the set ventilator rate The ventilator delivers partial mechanical breaths in response to patient effort Pressure Support (PS) is provided in addition to the set mandatory rate The size of the patient-initiated breaths is determined by lung compliance
3. What are the two main types of waveforms used to represent respiratory data in mechanical ventilation? Scalars and Loops Pressure/Volume/Flow and Time Ascending/accelerating ramp and Exponential decaying Square (constant) and Sine
4. What are the main determinants of end-tidal carbon dioxide (ETCO2)? Oxygenation levels, cardiac output, and CO2 production Alveolar ventilation, pulmonary perfusion, and CO2 production Hemoglobin concentration, lung compliance, and CO2 elimination Respiratory rate, tidal volume, and metabolic rate
5. What is the characteristic scalar feature of gas trapping or Auto-PEEP in mechanical ventilation? Lungs are fully deflating before the next breath is initiated Inspiratory flow does not reach the baseline before the next breath begins Expiratory flow does not reach the baseline before the next breath begins Auto PEEP is calculated during inspiratory hold maneuvers
