🟨Type 1 respiratory failure (T1RF): is characterised by
hypoxaemia (PaO2 < 8 kPa)
normal or low CO2.

🟨Type 2 respiratory failure (T2RF): is characterised by
hypoxaemia (PaO2 < 8 kPa) hypercapnia (PaCO2 > 6.5 kPa).

✳️Respiratory Conditions: Choice of investigations📝
__

✅Extrinsic upper airway obstruction assessment➝ Flow-volume loop

✅Expiratory obstruction (e.g. Asthma, COPD)➝ FEV1

✅Respiratory muscle strength assessment (e.g. GBS, Myasthenia gravis)➝ FVC

✅Assessment whether obstructive or restrictive lung disease➝ FEV1/FVC ratio
◾If ratio <0.7 indicates obstructive
◾If ratio is >0.7 indicates restrictive

✅Monitoring of Asthma➝ PEFR
