"Aortocaval compression resulting in sudden loss of consciousness and severe bradycardia and hypotension during cesarean section in a patient with subvalvular aortic stenosis". BMC Anesthesiology. 19 (1): 116. doi: 10.1186/s12871-019-0791-x. ISSN 1471-2253. PMC 6610927. PMID 31272377. AJ, Lee; R, Landau (2017).
In the second trimester, a standard ultrasound exam typically includes: [12] Fetal number, including number of amnionic sacs and chorionic sacs for multiple gestations; Fetal cardiac activity; Fetal position relative to the uterus and cervix; Location and appearance of the placenta, including site of umbilical cord insertion when possible
Positions included the "Coma Position", "Rautek's Position" and the "HAINES (High Arm IN Endangered Spine) position". In 1992, the European Resuscitation Council adopted a new position where the arm nearest the floor was brought out in front of the patient, whereas it had previously been placed behind the patient. This change was made due to ...
Depending on the situation, it may or may not be possible to save the patient and it may or may not be possible to save her fetus. But for both, a resuscitative hysterotomy is the best chance of survival. Prior to viability (approximately 24 weeks' gestation), it is not possible to save the fetus. It cannot survive outside the womb, but also ...
Pediatric advanced life support (PALS) is a course offered by the American Heart Association (AHA) for health care providers who take care of children and infants in the emergency room, critical care and intensive care units in the hospital, and out of hospital (emergency medical services (EMS)). The course teaches healthcare providers how to ...

A patient who received a 1:330 risk score, while technically low-risk (since the cutoff for high-risk is commonly quoted as 1:270), might be more likely to still opt for a confirmatory invasive test. On the other hand, a patient who receives a 1:1000 risk score is more likely to feel assuaged that her pregnancy is normal. [citation needed]
Cardiac output increases throughout early pregnancy, and peaks in the third trimester, usually to 30-50% above baseline. [6] Estrogen mediates this rise in cardiac output by increasing the pre-load and stroke volume, mainly via a higher overall blood volume (which increases by 40–50%). [ 22 ]
