Study Notes

Blood Pressure Measurement

Blood pressure is measured using a sphygmomanometer, which can be either mercury-based or aneroid.
The pressure in the cuff is calibrated in mmHg.
A stethoscope is used to listen for the Korotkoff sounds, which are caused by turbulent blood flow in the arteries as the pressure is released from the cuff.

Cardiac Cycle and Heart Sounds

The "lub" sound occurs when the mitral and tricuspid valves close, marking the start of systole (ventricular contraction).
The "dub" sound occurs when the aortic and pulmonic valves close, marking the end of systole and the start of diastole (ventricular relaxation).

Mean Arterial Blood Pressure (MAP)

MAP is the average arterial pressure throughout one cardiac cycle (systole and diastole).
MAP is calculated as: Diastolic Pressure + (Systolic Pressure - Diastolic Pressure)/3.
MAP is an important indicator of tissue perfusion, as it reflects the pressure driving blood flow to the organs.

Pulse Pressure

Pulse pressure is the difference between systolic and diastolic pressures.
It represents the pressure driving blood through the systemic circulation.
An increased pulse pressure can indicate increased stroke volume or decreased vascular compliance (stiffening of arteries).

Normal Heart Rates

The normal resting heart rate for adults and children over 10 years old is 60-100 beats per minute.
Well-trained athletes may have a normal resting heart rate of 40-60 beats per minute.
Newborns (up to 1 month old): 70-190 beats per minute
Infants (1-11 months old): 80-160 beats per minute
Children (1-2 years old): 80-130 beats per minute
Children (3-4 years old): 80-120 beats per minute
Children (5-6 years old): 75-115 beats per minute
Children (7-9 years old): 70-110 beats per minute
