BLOOD PRESSURE & PULSE DETERMINATIONS (Ex. 33)

STUDY
PLAY
SYSTOLE
Ventricular Contraction
DIASTOLE
Ventricular Relaxation
CARDIAC CYCLE
One complete heartbeat
DICROTIC NOTCH
Pressure fluctuation in the Aorta due to the closing of the Aortic Semilunar valve...kind of like pressure you feel when you close a door quickly and no windows are open...
S1 (Lub) (What is making this sound?)
Closing of AV valves: Tricuspid and Bicuspid (Mitral)
S2 (Dub) (What is making this sound?)
Closing of Semilunar valves: Pulmonary & Aortic
HEART MURMURS
Abnormal heartbeat patterns
AUSCULTATION OF AV & SEMILUNAR VALVES
Where doctors listen to your heart
PULSE
Surges of pressure of Left Ventricular contraction
PULSE PRESSURE
Difference between Systole & Diastole
PULSE RATE
Heartbeats per minute
SUPERFICIAL PULSE POINTS
ARTERIES:
- Superificial Temporal
- Facial
- Common Carotid
- Brachial
- Radial
- Femoral
- Popliteal
- Posterior Tibial
- Dorsalis Pedis
DIFFERENCE BETWEEN APICAL & RADIAL PULSE
Apical (Near the heart) is slightly faster than the Radial pulse due to distance from the heart.

Pulse Deficit: Greater lag in time due to:
1. Cardiac impairment
2. Low cardiac output
3. Abnormal heart rhythms
BLOOD PRESSURE
Pressure in the arteries (mm/HG) millimeters of mercury
SYSTOLIC PRESSURE
Measurement of pressure of Ventricular contraction
DIASTOLIC PRESSURE
Measure of pressure: Ventricular relaxation
SPHYGMANOMETER
BP Cuff
SOUNDS OF KOROTKOFF
Sounds of resumption of blood flow in forearm
MEAN ARTERIAL PRESSURE (MAP)
DP (Diastolic Pressure)

+

(PP (Pulse pressure)/3)
BP= CO x PR
Arterial BP = Cardiac Output x Peripheral Resistance

Peripheral Resistance:
1. Increase of Blood vessel constriction
2. Increase of Blood viscosity
3. Decrease of Arterial Elasticity
HARVARD STEP TEST
Measure of BP & pulse changes after step exercise
INDEX OF PHYSICAL FITNESS
Duration of exercise (seconds) x 100/ 2 + sum of 3 pulse counts in recovery (one minute each)
COLD PRESSOR TEST
BP change due to cold pain
HYPOREACTORS
Rise of Systolic/Diastolic from 0-22 mm/HG
HYPERREACTORS
Rise of Systolic/Diastolic 23 mm/HG and above
VASODILATION AND FLUSHING OF SKIN DUE TO LOCAL METABOLITES
Color and size of veins
EFFECTS OF VENOUS CONGESTION
Color and size of veins
COLLATERAL BLOOD FLOW
Like Circle of Willis, other source (routes) of blood flow
EFFECT OF MECHANICAL STIMULATION OF BLOOD VESSELS OF THE SKIN
Stimulate increase of blood flow into area & leaking of capillary fluid
