How is supine hypotension corrected during pregnancy?
PREVENTION AND TREATMENT Symptoms are usually transient and resolve with change in positioning, specifically left lateral position. With minimal compression of the vena cava by the gravid uterus, hemodynamic changes resulting in hypotension are mostly avoided.
Which side should a pregnant mother be turned to avoid supine hypotension?
For patients beyond the 20th to 24th week of gestation, the patient should be tilted 15° to the left by placing rolled towels beneath the spinal board. This is completed to prevent supine hypotension syndrome, which occurs when the gravid uterus compresses the inferior vena cava.

Can you lie supine during pregnancy?
(2017) identified maternal ACC syndrome and foetal hypoxia as plausible reasons for late stillbirth, and recommended that women in the third trimester of pregnancy should avoid going to sleep in a supine position. Left- sided sleeping was not conclusively shown to decrease the risk of stillbirth.
What are the signs and symptoms of supine hypotension?
Symptoms include pallor, dizziness, low blood pressure, sweating, nausea and increased heart rate; these are transient symptoms which resolve with maternal position change, such as leftward tilt.
Why can’t I sleep on my right side when pregnant?
The reason behind this is because the major blood vessels in the body (the aorta and the vena cava) run just next to the spine on the right side of the body. After about 20 weeks, the weight of the uterus can compress these vessels and decrease blood flow back to your heart and also to the baby.
What is supine hypotensive syndrome?
Conclusions: Supine hypotensive syndrome is characterized by severe supine symptoms and hypotension in late pregnancy, which compel the unconstrained subject to change position. Rarely, it may manifest even from the fifth month of pregnancy or postpartum, as well as in the pelvic tilt or sitting positions.
When should you stop lying supine while pregnant?

What happens if the mother lies supine during pregnancy?
During late pregnancy, the gravid uterus compresses the inferior vena cava (IVC) when a woman lies in the supine position. The azygos system of veins is the dominant pathway of collateral venous return back to the heart in the event of acute obstruction of the IVC.
Can I lay on my back at an angle while pregnant?
“As long as you’re not flat on your back, you’re going to be fine,” she says. “Even if you can be on a 20- to 30-degree angle, that’s going to relieve any potential pressure on your inferior vena cava. I think most women, even if they were back sleepers, can be comfortable sleeping with just that bit of an angle.”
What hypertension medications can you use during pregnancy?
