Pulse and Blood Pressure Laboratory Lecture Based on Seeley's

Laboratory lecture on pulse and pulse pressure

1. Exercise 37: Pulse and Pressure IRENE V. COLUMBANO, MD, DFM, FPAFP ATTY. JEAN JOAN POLIDO, MD JUNELLE DUMANGON, MD College of Medical Technology

2. Pulse Aka as pulse waves Formed as the heart pumps blood into the body The strong blood flow produces bulges in the arterial wall producing pressure waves Matches the rhythm of the cardiac cycle Gives information about the cardiovascular system

3. Pulse Points

4. Pulse Rate Determination Pulse rate – counting the number of pulses or pressure waves on the pulse points per minute Simply put your 2 nd and 3 rd digit on your radial artery and start counting the beats for a full minute. Do not use thumb! Take note of the strength and rhythm

5. Blood Pressure The strength of blood flow as it is delivered by the heart towards the rest of the body and exerts against the blood vessel walls The maximum value produced by the heart contraction is called systolic pressure The minimum value produced by heart relaxation is called diastolic pressure

6. Blood Pressure Determination Sphygmomanometer Unit: millimeters of mercury (mmHg) Measured based on hearing the Korotkoff sound Systolic pressure: point at which sound is first heard Diastolic pressure: Point at which sound stops

7. Blood Pressure Measurement

8. Blood Pressure Values

9. Pulse Pressure and Mean Arterial Pressure Pulse Pressure Difference between the systolic and diastolic pressure Pulse pressure = Systolic – Diastolic Mean Arterial Pressure (MAP) Average blood pressure in the arteries
