Vent-tastic Voyage
This ventilator variable initiates a breath.
What is the trigger?
This condition benefits most from PEEP therapy.
What is ARDS?
The normal PaO₂ range in a healthy adult.
What is 80-100 mmHg?
In pressure-control ventilation, this variable is set.
What is peak inspiratory pressure (PIP)?
This mode guarantees the delivery of a set tidal volume.
What is Volume Control Ventilation?
A patient with a VT of 500 mL and RR of 12 has this minute ventilation.
What is 6 L/min?
A patient with severe hypoxemia on FiO₂ 0.60 and PEEP 8 cmH₂O should likely have this increased.
What is PEEP?
A patient with PaO₂ 358 mmHg on FiO₂ 0.60 should have this decreased first.
What is FiO₂?
When lung compliance decreases during pressure-control ventilation, this variable decreases.
What is tidal volume?
This mode allows spontaneous breaths between mandatory breaths.
What is SIMV/IMV?
In volume control ventilation, this variable is set while airway pressure varies.
What is tidal volume?
Increasing PEEP beyond the optimal point may cause this compliance change.
What is a decrease in static compliance?
A PaO₂ of 48 mmHg despite FiO₂ 0.60 indicates this condition.
What is severe hypoxemia?
During volume-controlled ventilation, decreased compliance causes this pressure change.
What is an increase in PIP?
This mode uses a set inspiratory pressure while tidal volume varies.
What is Pressure Control Ventilation?
The total cycle time for a patient breathing 16 breaths/minute.
What is 3.75 seconds?
This maneuver helps keep alveoli open at end expiration.
What is PEEP?
This oxygenation parameter is most commonly titrated first when PaO₂ is excessively high.
What is FiO₂?
A pressure-volume loop with a "beak" appearance indicates this.
What is alveolar overdistention?
A patient-triggered and patient-cycled breath is considered this type of breath.
What is a spontaneous breath?
This is the most important prerequisite before beginning ventilator weaning.
What is improvement of the underlying disease process?
In ARDS management, this ventilator strategy is used alongside PEEP to prevent volutrauma.
What is low tidal volume ventilation (6 mL/kg IBW)?
A patient has pH 7.20, PaCO₂ 88, and PaO₂ 42. This type of respiratory failure is present.
What is acute hypercapnic respiratory failure?
In pressure-control ventilation, improved compliance with the same pressure setting causes this.
What is an increase in tidal volume?
This ventilator mode guarantees a set tidal volume and minute ventilation, making it a common choice for fully ventilated patients.
What is Volume Control Ventilation (VCV)?
