- Volume control ventilation guarantees
Show answer
A set tidal volume with each breath, while pressure varies- Pressure control ventilation guarantees
Show answer
A set inspiratory pressure with each breath, while tidal volume varies- Assist-control (A/C) mode delivers
Show answer
A full set breath, whether patient-triggered or machine-triggered- SIMV stands for
Show answer
Synchronized intermittent mandatory ventilation- In SIMV, spontaneous breaths between mandatory breaths receive
Show answer
Only the level of support the patient generates, sometimes with pressure support added- Pressure support ventilation (PSV) is used for
Show answer
Augmenting spontaneous breaths, commonly during weaning- PEEP stands for
Show answer
Positive end-expiratory pressure- Primary purpose of PEEP
Show answer
Preventing alveolar collapse and improving oxygenation by increasing functional residual capacity- A typical starting PEEP for a patient without lung disease
Show answer
Around 5 cm H2O- FiO2 stands for
Show answer
Fraction of inspired oxygen- A normal starting tidal volume for lung-protective ventilation
Show answer
6 to 8 mL per kg of ideal body weight- Lung-protective ventilation targets a plateau pressure below
Show answer
30 cm H2O- Plateau pressure is measured by
Show answer
Applying an inspiratory hold at end-inspiration- Plateau pressure primarily reflects
Show answer
Static lung and chest wall compliance- Peak inspiratory pressure reflects
Show answer
Both airway resistance and lung/chest wall compliance
