1

What are the two types of mechanical ventilation?

Volume Cycled Ventilation (VCV)
Pressure Cycled Ventilation (PCV)

2

Volume Cycled Ventilation delivers a preset...

Tidal Volume and Flow

3

Pressure Cycled Ventilation delivers ...

Air for a preset inspiratory time, and until set pressure is reached

4

What are the invasive methods of delivery/intubation of ventilation?

Endotracheal tube
Nasotracheal tube
Tracheostomy tube

5

What are the invasive modes of ventilation

Control Ventilation
Assist Control Ventilation
Synchronised Intermittent Mandatory Ventilation
Pressure Support Ventilation

6

In Assist Control Ventilation, what happens when the patient initiates a breath?

The ventilators will deliver breath

7

In Assist Control Ventilation, what happens if the patient doesn't breathe?

The ventilator will trigger AND deliver breaths

8

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"

9

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

10

In Pressure Support Ventilation, the patient is ______________ breathing

"SPONTANEOUSLY" breathing

11

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

12

In Assist Control Ventilation, is the patient spontaneously breathing?

Doesn't matter, can be spontaneously breathing or not

13

In control ventilation, is spontaneous breathing required?

No it is not required

14

In control ventilation, the patient's efforts are _____

Ignored

15

Prolonged use of Control Ventilation can lead to what with prolonged use?

Respiratory muscle atrophy with prolonged use

16

What can result if the patient is able to trigger in Control Ventilation?

Patient-Ventilator Dysynchrony

17

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)

18

In volume cycled ventilation, why will pressure in lungs vary?

Depending on lung compliance and resistance

19

In pressure cycled ventilation, why will volume in lungs vary?

Depending on airway resistance and lung compliance (stiffer lungs -> smaller volumes)
