ETCO2 Monitor

Question 1

PPE

Answer 1

Hand sanitiser
Disposable gloves
Clinical waste bag

Question 2

Explanation

Answer 2

EtCO2 is the concentration of CO2 in exhaled air and
approximates the partial pressure of CO2 in arterial blood

Waveform capnography during advanced life support uses
waveform capnography to confirm correct tracheal tube
placement and to monitor the quality of CPR.

An increase in ETCO2 during CPR may indicate that ROSC has
occurred.

Question 3

Readings

Answer 3

Normocapnia
4.6-6.0 kPa

Minimum reading
compatible with
potential ROSC in
cardiac arrest is
1.33 kPa

Question 4

Indications

Answer 4

Patients in respiratory/cardiac arrest requiring airway management

Question 5

Building the airway tree

Answer 5

1. Tube / iGel
2. Catheter mount
3. Filter (Prevents contamination from airway)
4. Capnography
5. BVM

Question 6

Assess ventilation

Answer 6

Squeeze the bag to ventilate the patient to assess efficacy.

It may take 6 ventilations to return an accuare ETC02 measurement

Question 7

Monitor the ETO2

Answer 7

Diminishing EtCO2 readings may be an indication to increase chest compression depth or change a tiring CC provider to optimise CPR
attempts.

Question 8

Report

Answer 8

Record /
document ETC02
reading in kPa
