Blood pressure Definition

• Blood pressure
• Pressure exerted against blood vessel walls
  (mostly arteries) every beat, expressed in
  millimeters of mercury.
• Systolic blood pressure
• Pressure exerted against blood vessel walls
  during ventricular contractions. Represents
  overall function of the left. Should it go up or
  down during exercise?
• Diastolic blood pressure
• The lowest blood pressure against blood vessel
  walls during ventricle filling. Signifies
  arterial peripheral resistance. Should it go up
  or down during exercise?
• Hypertension
• Chronically elevated resting blood pressure
  (either or both systolic/diastolic blood
  pressure).
• Hypotension refers to low blood presser (no
  norms)

Heart Rate

• Heart Rate
• Number of times the heart contracts (usually in
  one minute - BPM)
• No known standard average RHR is approximately
  60 BPM
• Marker of cardiovascular fitness. Why and How?

Blood Pressure Measurement

• Used in the decision making process regarding
  cardiovascular testing
• For accuracy, several measurements must be taken
  over time (two more visits). Why?
• How it works
• Pressure inside the cuff restricts blood flow
  within the artery
• No sound can be heard initially through the
  stethoscope
• Pressure is slowly released from the cuff
  pressure inside the cuff is equal to the systolic
  pressure inside the artery.
• The first Korotkoff sound can be heard take
  note of this number (systolic)
• Turbulent sound from blood flow can be heard
• The blood flow can no longer be heard when cuff
  pressure is equal to diastolic pressure within
  the artery.
