39
Q

why is it harder to resuscitate a pregnant woman

A

pregnant uterus causes aortocaval compression
pressure on diaphragm causes ventilation difficulty
foetus “steals” oxygen therefore at more risk of hypoxia
more likely to aspirate due to hormonal relaxation of oesophageal sphincters
more difficult to intubate

Keep mother in supine position and apply left MUD to displace uterus to relieve pressure on aorta and vena cava which improves venous return to the heart

ensure no one is touching the patient

ensure oxygen mask is far away
