if a large volume of fluid has shifted from the blood into the peritoneal cavit, how would this affect bv?

Answer 1

It depends on how rapidly the shift is occurring. Most of the time it happens slowly enough that the kidneys are able to compensate, thus the blood volume would remain within normal parameters. However if it is rapid like in an intraabdominal hemorrhage, blood volume would definitely drop.

Answer 2

when large volume of fluid shifted into peritoneal cavity, a lots of fluid is collected and condition known as Ascites is occur. The effect of loss of fluid from the blood cause lower blood pressure, feeling dizziness, change in consciousness, cold and clammy skin and extremities, scanty of urine and sometime so serious that can lead to failure of the function of kidney, increase heart rate or palpitation. Due to collection of fluid in abdomen it compress on on the organ and neighboring structure. If press on lung, cause tierdness and increase breathing rate. If compress on heart, cause tightness of chest. If compress on stomach and intestine, cause vomiting, indigestion, discomfort in abdomen. sometime it may press on the liver and cause obstruction of the venous return of the liver.
