Haemodynamic effects from aortocaval compression at different angles of lateral tilt in non-labouring term pregnant women†‡

Patients with ACC can be identified by the CO changes from serial measurements between supine, 15°, or full lateral tilt. Our findings suggest that in non-labouring parturients, ACC is asymptomatic and can be effectively minimized by the use of a left lateral tilt of 15° or greater.
