In a volume-targeted ventilator mode, what happens when the patient’s lung mechanics change?

A
It targets inspiratory pressure, so tidal volume is fixed.
B
It targets a set tidal volume, while airway pressure can vary.
C
It targets a fixed plateau pressure, regardless of lung mechanics.
D
It provides patient-triggered breaths without a mandatory rate.

Which statement correctly distinguishes CPAP from bilevel noninvasive ventilation (NIV)?

A
CPAP uses higher pressure during inspiration than expiration; bilevel NIV uses one continuous pressure.
B
Both CPAP and bilevel NIV provide one continuous pressure.
C
CPAP provides one continuous pressure; bilevel NIV uses higher pressure during inspiration than expiration.
D
CPAP provides invasive support through an endotracheal tube; bilevel NIV is mask-based.

A ventilated patient’s high-pressure alarm sounds. What is the most appropriate initial response?

A
Assess the patient, tubing, and airway for a cause such as coughing, kinking, secretions, or bronchospasm.
B
Silence the alarm and wait to see whether it recurs.
C
Disconnect the ventilator before checking the patient.
D
Increase ventilator pressure until the alarm stops.

Review delivered tidal volume, respiratory rate, and relevant waveforms.
C
Check endotracheal-tube position and circuit connections.
D
Rely on displayed values instead of assessing the patient.

A patient is receiving pressure-targeted ventilation. If airway resistance increases, which change is consistent with how this mode works?

A
The ventilator keeps tidal volume fixed while airway pressure varies.
B
The ventilator sets a mandatory rate and does not support patient-triggered breaths.
C
The ventilator targets inspiratory pressure, so tidal volume can change as lung mechanics change.
D
The ventilator provides one continuous pressure throughout inspiration and expiration.

A patient using mask-based noninvasive ventilation needs pressure support during inspiration as well as oxygenation. Which description best fits bilevel NIV?

A
It uses higher pressure during inspiration than during expiration.
B
It provides the same continuous pressure during inspiration and expiration.
C
It requires an endotracheal tube to deliver positive pressure.
D
It sets a mandatory respiratory rate without supporting spontaneous breaths.

A ventilator is set to deliver a target tidal volume. As the patient's lung mechanics change, what should be expected in a volume-targeted mode?

A
Airway pressure is fixed, and tidal volume varies with lung mechanics.
B
Tidal volume is targeted, and airway pressure varies with lung mechanics.
C
Both tidal volume and airway pressure are fixed regardless of lung mechanics.
D
The mode provides patient-triggered breaths without a target volume or pressure.

A patient is taking spontaneous breaths during a breathing trial. Which mode characteristic makes pressure support suitable for this situation?

A
It sets a minimum rate and supports every patient-triggered breath.
B
It targets a fixed tidal volume for every breath and sets a mandatory rate.
C
It assists patient-triggered breaths without setting a mandatory rate.
D
It delivers one continuous pressure regardless of whether the patient breathes.
