Question
Blood Pressure Worksheet Indicate whether each of the following manipulations would result in an Increase [u. Decrease [D] or have No effect [N] on Mean Arterial Blood Pressure (MABP). For eaclh answer given, explain the logic behind your decision. Manipulation MABPRationale Increased cardiac output Increased hematocrit Decreased Ach release to SA node Dehydration Decreased blood volume Increased skeletal muscle activity/ exercise Decreased respiratory rate NE or Epinephrine administration Decreased total eripheral resistance Vasopressin administration Decreased sympathetic firing at SA node Increased venous return Blood loss due to injury Anemia Sitting up after lying down Decreased heart rate Vasodilation IV Infusion of normal salineExplanation / Answer
1. Increased cardiac output- Increase in MABP.
Rationale: MABP=Cardiac output × systamic vascular resistance+ central venous pressure.
2.Increased hematocrit results in increased MABP. As the hematocrit Increased the thickness of blood also increased and results in increased PVR.
3. Decreased ach releases causes Decreased in the cardiac muscle contraction and results in decreased MABP
4. Dehydration causes Decreased volume of fluid in the body and causes Decreased mabp
5. Decreased blood volume also causes Decreased in MABP.
6. Exercise causes increased need of blood to the muscles causes increased MABP.
7.Decreased respiration causes Metabolic Acidosis that makes heart to beat faster to compensate the co2. So the mabp is increased.
8.Ne or E administration causes increased cardiac output results in increased MABP.
9.Decreased total peripheral resistance causes decrease in MABP.
10. Vasopressin results in decreased pvr and decreased MABP.
