Question
Blood Pressure Worksheet Indicate whether each of the following manipulations would result in an Increase [1. Decrease [D] or have No effect [N] on Mean Arterial Blood Pressure (MABP). For each answer given, explain the logic behind your decision. Manipulation MABP Rationale Increased carcdiac output Increased hematocrit Decreased Ach release to SA node A nodech Dehydration Decreased blood volume Increased skeletal muscle activity/ exercise Decreased respiratory rate NE or Epinephrine administration Decreased total peripheral 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
Manipulation
MAPB (mean arterial blood pressure)
Rationale
Increased cardiac output
Increased
As higher pumping of blood makes a higher impact on the arterial walls
Increased hematocrit
Decreased
Hct determines blood viscosity, Increasing blood viscosity via an increase in hematocrit reduces peripheral vascular resistance, lowering MA blood pressure
Decreased Ach release to SA node
increased
As its release decrease the MABP
Dehydration
decrease
As it decrease the ionic level in blood
Decrease blood volume
decrease
Decrease venous pressure is the reason
Increased skeletal muscle activity/excercise
increased
Increased cardiac output
Redistribution of blood flow
Decreased respiratory rate
increased
as increase in the variation of
pulse pressure blood pressure swings increases with decreasing respiratory rate
NE or Epinephrine administration
increased
epinephrine can produce an initial increase in mean arterial blood pressure
Decreased total peripheral resistance
decrease
to cardiac output (CO) x peripheral resistance (R)
Vasopressin administration
increased
vasopressin administration increased mean arterial pressure as the retention of fluid
Decreased sympathetic firing at SA node
decreased
decrease vagal tone
Increased venous return
increased
Increase in stroke volume and pulmonary blood flow.
Blood loss due to injury
decreased
Decreased fluid level
Anemia
increased
The reason for the increased cardiac output in anemia
Sitting up after lying down
decresed
When shifting from lying down, known as the supine position, orthostatic hypotension
Decreased heart rate
decreased
As low blood flow
Vasodilation
decresed
Low pressure on vessles
IV infusion of normal saline
increased
As the fluid content increases
