An Introduction to ITU & Critical care

Question 1

Methods of delivery/intubation for ventilation?

Answer 1

• Non Invasive
• Endotracheal
• Nasotracheal
• Tracheostomy

Question 2

What are the two types of ventilation we learned about?

Answer 2

Volume Cycled (VCV)
Pressure Cycled (PCV)

Question 3

Volume Cycled Ventilation delivers …

Answer 3

Delivers a preset tidal volume and flow

Question 4

Pressure Cycled Ventilation delivers …

Answer 4

Delivers air for preset inspiratory time, and until set pressure reached

Question 5

In pressure cycled ventilation why may the volume of air delivered vary?

Answer 5

Could be because of airway resistance / lung compliance . Stiffer lungs -> smaller volumes

Question 6

What are some modes of ventilation?

Answer 6

• Control (CMV)
• Assist Control (AC)
• Synchronised Intermittent Mandatory Ventilation (SIMV)
• Pressure Support Ventilation (PSV)

Note: these are the invasive modes

Question 7

In controlled ventilation the ventilator does …

Answer 7

All the work

Question 8

Controlled ventilation can lead to respiratory muscle atrophy with prolonged use

True or False

Answer 8

True

Question 9

In volume cycled ventilation, pressure in the lungs will vary depending on

Answer 9

lung compliance and resistance

Question 10

What are some of the reasons / indications for INTUBATION?

Answer 10

• Airway patency: Obstruction
• Airway protection: Swallow
• Airway clearance: Suctioning

Question 11

The indications for ventilation is usually

Answer 11

Respiratory failure

• Obstructed upper airway
• Poor gas exchange
• Respiratory muscle failure
