Question 1

Identify the indications for End Tidal CO2 monitoring

Answer 1

• anaethesia
• procedural sedation
• intubation
• cardiac arrest
• ventilation

Question 2

Identify the normal CO2 level

Answer 2

35-45mmHg

Question 3

Identify the significance of a high and a low ETCO2

reading and the management of each

Answer 3

• less than 35 (hyperventilation)
• greater than 45 (hypoventilation)
  Check airway
  Check equipment
  Identify physiological cause (e.g. severe hypotension, apnoea, PE, etc)

Question 4

Identify ETCO2 trouble shooting strategies

Answer 4

check monitor, check lines and tubes, check airway, etc

Question 5

Draw and discuss the significance of a normal ETCO2 waveform

Answer 5

Phase I - inspiration
Phase 2 - Beginning of expiration (expiratory upstroke)
Phase 3 - Expiration continues, represents alveolar CO2
Phase 0 - beginning of inspiration (inspiratory down stroke)

Question 6

Demonstrate calibration of the ETCO2 sensor

Answer 6

calibrate on monitor
