<prompt> All of the following physiological changes are seen in pregnancy except:Increased stroke volumeIncreased cardiac outputIncreased intravascular volumeIncreased peripheral resistance  <response>: Ans. d. Increased peripheral resistance Ref: Dutta 6e p53, 51During the physiological course of pregnancy, maternal peripheral vascular resistance decreases.Pregnancy is a state of hypervolemia. There is active retention of sodium 900 mmol, potassium 350 mmol and water.- Dutta 6e p51Hemodynamic Changes during Pregnancy Non-PregnantPregnancy near TermChangeCardiac output litermin4.56.2640Stroke volume ml657527Heart rate per minute708517Blood pressureUnaffected or mid-pregnancy drop of diastolic pressure by 5-10 mm HgVenous pressure8-10 cm femoral20 cm water100 waterColloid oncotic pressure2018-14Systemic vascular resistance -21Pulmonary vascular resistance -34
