Effect of the left lateral recumbent position compared with the supine and upright positions on placental blood flow in normal late pregnancy… Ten patients were moved from the left lateral recumbent position to the upright position, which caused a statistically significant 23% decrease in the mean accumulation rate. The semi‐recumbent position was defined as having the woman supine with the cephalad end of the examination couch raised to a measured 30 deg from the horizontal and one pillow was provided. Am J Obstet Gynecol. Am J Obstet Gynecol 1997;176:642-3) state that indirect blood pressure measurement in the left lateral position with the cuff on the left arm will overestimate blood pressure. There is no published information about the prone position in women with preeclampsia. Squatting was the position most commonly associated with tears (42% avoided tears). The clinical significance of the haemodynamic changes produced by alterations in posture are briefly discussed.

The lateral position and the upright position have been found to improve the quality of uterine contractions. [Risk of pregnancy complications associated with residency]. Otherwise, the location selected should have a roof and some protection from the elements. To evaluate blood pressure in pregnant women in the left lateral position, we studied indirect blood pressure in 169 patients with normal blood pressure, chronic hypertension, and preeclampsia in the supine and then the lateral recumbent positions.

A positive SPT has been previously defined as an increase of at least 20 mmHg in diastolic BP when switching between left lateral recumbent and supine positions. The semi‐recumbent position was defined as having the woman supine with the cephalad end of the examination couch raised to a measured 30 deg from the horizontal and one pillow was provided. Regarding direct aortic arch blood pressure, (1) supine blood pressure equaled that in the lateral position and (2) direct blood pressure in the lateral position equaled the mean indirect mean arterial pressure of both arms.
