FP-C Ventilator Management and Respiratory Support 2

Question 1

Auto-PEEP (intrinsic PEEP) in a mechanically ventilated patient is best described as:

Accepted Answer

Air trapping due to incomplete exhalation before the next breath

Answer

Auto-PEEP results from air trapping when expiratory time is insufficient for complete exhalation, increasing baseline alveolar pressure.

Question 2

A patient with severe asthma is intubated and mechanically ventilated. SpO2 is 94% but bilateral breath sounds are absent. Ventilator shows high peak pressures. The FIRST action should be:

Accepted Answer

Disconnect from the ventilator and manually bag slowly

Answer

Severe auto-PEEP causing tension physiology requires immediate disconnection to allow passive exhalation and decompress trapped air.

Question 3

A high-pressure alarm is triggered on the transport ventilator. Which of the following is the LEAST likely cause?

Accepted Answer

ETT cuff deflation

Answer

ETT cuff deflation would cause a leak and low-pressure/low-volume alarm, not a high-pressure alarm.

Question 4

Permissive hypercapnia during mechanical ventilation is defined as intentionally allowing PaCO2 to rise above normal in order to:

Accepted Answer

Minimize tidal volumes and ventilator-induced lung injury

Answer

Permissive hypercapnia accepts elevated PaCO2 as a trade-off for using lower tidal volumes that reduce ventilator-induced lung injury.

Question 5

Patient-ventilator dyssynchrony during transport is BEST identified by:

Accepted Answer

Observation of patient effort against the ventilator and irregular waveforms

Answer

Dyssynchrony is identified by observing the patient fighting the ventilator, accessory muscle use, and irregular flow/pressure waveforms on the ventilator.
