Ventilator - select what 3 things? - Answer✅✅1. TYPE of ventilator
2. Ventilator MODE
3. CONTROL variable (how breath is delivered within mode)
Non-invasive ventilation (NIPPV) - Answer✅✅CPAP/BiPAP
Invasive Ventilation (IPPV) - Answer✅✅Full ventilatory supports (FVS)
Partial ventilatory support (PVS)
CPAP (continuous positive airway pressure) - Answer✅✅Improves oxygenation
Treat cariogenic pulmonary edema
May be used in *stable COPD (patients with increases resistance)
Enhances surface area - making gas exchange easier
BiPAP (bilevel positive airway pressure) - Answer✅✅Manage disorders such as
COPD, CF, MS, ALS
Reduces the need for intubation by 60-75%
Pressure triggered, pressure limited, flow cycled
Major Non-invasive ventilation advantage - Answer✅✅Preserve airway defenses -
avoid infection
, Once IPPV deemed necessary, select _______ - Answer✅✅Mode
FVS vent rates - Answer✅✅8 or greater
To maintain tidal volume
Tidal volume is determined by? - Answer✅✅Patient's IBW and height
FVS mode - Answer✅✅Assist/control (AC)
AC Mode of Ventilation - Answer✅✅FVS vent
Pressure or volume pre-set
FVS always used in ____ patients to rest respiratory muscles - Answer✅✅ARF
PVS vent rates - Answer✅✅Less than 6
PVS modes - Answer✅✅Intermittent mandatory (IMV)
Pressure or volume support (PSV)
Proportional assist (PAV)
Mandatory minute (MMV)
When should you paralyze and sedate ventilated patients? - Answer✅✅Only when
the ventilator is delivering true controlled breaths
Ventilator mode definition - Answer✅✅Breath type and pattern delivery during
mechanical ventilation
Mode is determined by 3 factors - Answer✅✅1. Type of breath: mandatory,
spontaneous, assisted
2. Targeted control volume: volume or pressure
3. Timing of breath delivery: continuous (AC or CMV), intermittent mandatory (IMV)
or continuous spontaneous (CSV)
3 types of breaths - Answer✅✅1. Mandatory
2. Assisted - patients initiates breath all else controlled
3. Spontaneous - volume or pressure controlled
Goal of volume controlled ventilation - Answer✅✅Maintain a certain level if PaCO2
Disadvantage of volume controlled ventilation - Answer✅✅Pressure rises an
overdistension may occur
greater than 30 cmH2O dangerous
Settings in volume controlled ventilation - Answer✅✅User sets:
Tidal volume (IBW)
Rate (usually start at 60 lpm)
Trigger sensitivity (-1 to -2 mmHg)
