Q

What is Type 1 Respiratory Failure and what PaO2 indicates T1RF?

A

Type I respiratory failure is also known as hypoxaemic failure, and is defined by a PaO2 of less than 8kPa. It indicates a serious underlying pathology with the lungs such as infection, oedema or a shunt.

Q

What is Type 2 Respiratory Failure and what PaCO2 indicates T2RF?

A

Type II respiratory failure is also known as ventilatory failure, results when PaCO2 is more than 7. Reduced ventilatory effort can be a result of gas trapping, such as in COPD and severe asthma, due to chest wall deformities, muscle weakness or central causes of respiratory depression.

Q

You are asked to review an ABG on a patient in the Emergency department who has been admitted with shortness of breath and is known to have COPD. You are told that they have a GCS of 15. The ABG shows:

FiO2 35% oxygen via venturi mask
SaO2 98%
pH 7.31
pCO2 7.8 kPa
pO2 13.6 kPa
HCO3 22.1 kPa
BE -4.5

What does the ABG show? And what would be the best next step in management?

A

Uncompensated type II respiratory failure.

Reduce the amount of inspired oxygen.
