Q
Indications for invasive BP monitoring
A
- Patient unstable e.g. hypovolaemia
- Critical perfusion states e.g. carotid stenosis
- Deliberate induced hypotension e.g. middle ear surgery
- Movement artefact e.g. during transfer
7
Q
Pulse oximeter mechanism
A
Differences in absorption of Red light vs infrared by oxy Hb vs deoxy Hb

Q
Formula used by pulse oximeter to calculate sats
A
SpO2 = 100 x [HbO2] / [Deoxy Hb] + [HbO2]
