Flashcards in Mechanical Ventilation Deck (19)
What are the two types of mechanical ventilation?
Volume Cycled Ventilation (VCV)
Pressure Cycled Ventilation (PCV)
Volume Cycled Ventilation delivers a preset...
Tidal Volume and Flow
Pressure Cycled Ventilation delivers ...
Air for a preset inspiratory time, and until set pressure is reached
What are the invasive methods of delivery/intubation of ventilation?
What are the invasive modes of ventilation
Assist Control Ventilation
Synchronised Intermittent Mandatory Ventilation
Pressure Support Ventilation
In Assist Control Ventilation, what happens when the patient initiates a breath?
The ventilators will deliver breath
In Assist Control Ventilation, what happens if the patient doesn't breathe?
The ventilator will trigger AND deliver breaths
In SIMV (Synchronised Intermittent Mandatory Ventilation) if the patient doesn't trigger a breath, the ventilator will give a ________ breath
If the patient takes a spontaneous breath, the ventilator gives ________ ___________
if the patient doesn't trigger a breath, the ventilator will give a "CONTROL" breath
If the patient takes a spontaneous breath, the ventilator gives "PRESSURE SUPPORT"
In SIMV (Synchronised Intermittent Mandatory Ventilation), what happens if the patient does a spontaneous breath during another breath?
The ventilator will modify the breath delivered to prevent breath stacking
In Pressure Support Ventilation, the patient is ______________ breathing
In pressure support ventilation, the ventilator will detect what and do what?
It will detect the patient's respiratory effort and deliver and a +ve pressure to assist the patient's breath
In Assist Control Ventilation, is the patient spontaneously breathing?
Doesn't matter, can be spontaneously breathing or not
In control ventilation, is spontaneous breathing required?
No it is not required
In control ventilation, the patient's efforts are _____
Prolonged use of Control Ventilation can lead to what with prolonged use?
Respiratory muscle atrophy with prolonged use
What can result if the patient is able to trigger in Control Ventilation?
What is PIP?
Peak Inspiratory Pressure; the maximum pressure that is reached during inspiration
(note: we want to keep it below 40 as high PIP can result in barotrauma)
In volume cycled ventilation, why will pressure in lungs vary?
Depending on lung compliance and resistance
