Pregnancy is a hyperdynamic state of circulation.
1.Blood volume increases by almost 40-50%.[peaks in 28-32 weeks of gestation]
2.Plasma volume increases to the tune of 40%.
3.Anemia[due to discrepapancy of the rise of blood volume & plasma volume and also due to iron deficiency]
4.Decreased oxygen carrying capacity of blood.[this is compensated by several mechanisms like increase in cardiac output,decreasing blood viscosity,vessel dilatation etc]
5.Due to the effect of estrogen & progesterone[these hormones rise during pregnancy] dilates the blood vessels so there is a fall in the resistance offered by the blood vessels[systemic vascular resistance & pulmonary vascular resistance]
6.Increase in cardiac output[peaks during 22-28 weeks of gestation].
7.Increase in stroke volume[the blood pumped by the heart with each heart beat].
8.Red blood cell volume also increases to the tune of 20%.
9.heart beat increases during pregnancy by 12-16beats/minute[this may give rise to palpitation i.e becoming conscious about your heart beat]
10.Alteration of blood pressure:Systolic blood pressure and diastolic blood pressure,both fall to a minor extent,but the changes are more marked in diastolic blood pressure.
11.Pedal edema[swelling around the ankles,which pits on application of pressure].
12.Some ECG changes.[ST-T changes]
13.some findings are also observed on auscultation of the heart[examination of the chest with a stethoscope] like murmurs,increased splitting of heart sounds,S3 gallop etc.
14.Decrease in blood viscosity.
15.Shift of the oxygen hemoglobin dissociation curve to the right.

Yes,i know i could not explain a few terms in a more simple way ,because i thought they will be a bit out of the extent of this post,but still if you find this post informative,please subscribe.
