Vents Quiz 1-1

Front 1

what are the four phases of a mechanical breath?

Back 1

trigger phase, inspiration or limit phase, cycle phase, expiratory phase

Front 2

what are the four types of breathing in mechanical ventilation?

Back 2

spontaneous, mandatory, assisted, supported

Front 3

29. While observing a patient receiving ventilatory support, you notice that all delivered breaths are initiated or terminated by the machine. What mode of ventilatory support is in force?

Back 3

Continuous mandatory ventilation

Front 4

While observing a patient receiving ventilatory support, you notice that some delivered breaths are begun or ended by the machine, whereas others are begun and ended by the patient. Which mode of ventilatory support is in force?

Back 4

Intermittent mandatory ventilation

Front 5

A mode that allows spontaneously breathing patients to breathe at a positive-pressure level, but drops briefly to a reduced pressure level for CO2 elimination during each breathing cycle is also known as:

Back 5

Airway pressure release ventilation

Front 6

Mean airway pressure is highest with what waveform?

Back 6

Descending ramp flow waveform

Front 7

Which ventilator controls are used to alter the breath size in pressure control ventilation?

Back 7

PIP and PEEP

Front 8

• The ventilator circuit is approximately ______ of plastic tubing. Generally, _____ in size

Back 8

60 in long, 22mm in size

Front 9

the compressibility factor:

Back 9

PIP – PEEP x compressibility factor ml/cm H2O = the amount to be subtracted from the total tidal volume
