What are the 3 groups that cause third space shifts?
1. Hypoalbuminemia- low albumin in blood (from malnutrition or severe liver damage).
2. Inflammation- (most common) damaged cells become leaky. (burns, belly surgery, bowel obstruction, peritonitis, pleural effusion)
3. Increased venous pressure- * heart failure, right side can't keep up with the demand so the blood backs up in the body. * liver disease, the liver becomes hard and blood can't get thru so blood backs up into the belly.
