Why the study?
Clinical guidelines emphasize maternal positioning during CPR due to aortocaval compression by the gravid uterus, but evidence regarding which position is most effective was limited.
Does the 27°-30° left-lateral tilt position improve the quality of chest compressions during maternal CPR compared to the supine position?

Left-lateral tilt yields inferior chest compression quality versus supine with manual displacement; challenges guideline positioning recommendations in pregnancy CPR.
Does the 27°-30° left-lateral tilt position improve the quality of chest compressions during maternal CPR compared to the supine position?
During maternal CPR, the supine position (with manual left uterine displacement) allows for higher quality chest compressions compared to the 27°-30° left-lateral tilt position.
