Physiologic and anatomical changes during pregnancy help ensure that: 3
driven by- |
|
Definition
1. fetal and maternal needs for nutrients/oxygen are met 2. conditions for labor/delivery are optimal 3. prepared for lactation
hormones |
|
|
Term
| Within the first -- wks of pregnancy increase in blood plasma (volume), creates- |
|
Definition
20
hemodilution= increased plasma disproportionate to in RBC mass |
|
|
Term
| Physiological anemia of pregnancy |
|
Definition
decrease concentration of RBC/unit of blood (not a true anemia)
RBC count increased, but plasma increases more.
This lowers iron |
|
|
Term
| Increased cardiac output (to push blood to fetus) is accomplished by |
|
Definition
Increase in heart rate (bpm) - Resting 10-20 beats per minute (70 bpm to 80-90 bpm)
Increased stroke volume (bl/bt) – heart contracts more forcefully |
|
|
Term

|
Term
| Elevated levels of progesterone and estrogen during pregnancy |
|
Definition

(enhance digestion and nutrient absorption) |
|
|
Term
|
Definition
relaxed sphincter
worse at end of preg due to pressure |

|
Term
|
Definition
| food moves slower= increased water absorption |
