Слайд 3Indication and consequences of the mentioned change.
Change in heart

shape and position:-
The heart moves upwards and to the left

usually. This occurs due to increase in uterus size pushing on the diaphragm. The heart also grows in size to increase the CO to pump more blood to the fetus and mothers vital organs.
Consequently this leads to :
2. Apex beat shift: It shifts to 4th ICS, left of MCL.
3. Additional heart sounds: There is accentuation of 1st heart sound, there maybe systolic murmers, and 3rd heart sound.
4. Tachycardia: To increase the CO.

5. Increase in Circulating BV:-
The volume of blood

plasma in pregnancy begins to increase from the 10th week

of pregnancy. The intensive increase of volume of circulating blood plasma proceeds to 34th week of pregnancy, after that the increase proceeds, but considerably slower. The amount of red blood cells (RBC) is also multiplied, but to a lesser degree[3].
As a result, oligocythemic anemia and decrease of blood viscosity occur. Therefore, the relative decrease of hemoglobin volume, called “hydremia of pregnancy”, or physiological hypervolemia (autohemodilution), usually takes place almost in every pregnant woman.

Слайд 57. Decrease peripheral resistance: The decrease of common and peripheral

resistance of vessels is explained by formation of utero-placental circle

of blood circulation. Moreover, vasodilatory action of progesterone and estrogen may affect it.

8. Edema: The central venous pressure is raised on average .The pressure in the veins of upper extremities does not change. The pressure in veins of lower extremities increases. Partially it is due to force of gravity, partially — due to obstacle to backflow of blood from uterus and placenta.

The gravid uterus produces a compression effect on the inferior vena cava, when the patient is in supine position. Worsening of vein outflow through the lumbar and paravertebral veins, and reduction of minute cardiac volume cause a collapse in some women. Therefore, the position on the back is not recommended for pregnants.

7. Decrease peripheral resistance: The decrease of common and peripheral resistance of vessels is explained by formation

Слайд 7Hematological changes
The total number of leucocytes is multiplied from 7,500

to 10,000 per mm3[4].
ESR (erythrocytes sedimentation rate) amounts to

50 mm.
The quantity of thrombocytes is approximately doubled running by the term up to 316,000 per mm3. This increases chances of DVT in pregnant women.
In the II and III trimester of pregnancy the content of coagulate factors in blood increases, the prothrombin index rises. The rate of blood coagulation gradually increases; the structural properties of blood clot are enhanced.
Hematological changesThe total number of leucocytes is multiplied from 7,500 to 10,000 per mm3[4]. ESR (erythrocytes sedimentation
