6What is pulse“The pulse is the bounding of blood flow in an artery that is palpable at various points of the body. It is caused by the stoke volume ejected during systole and distension of the walls of the aorta, which creates a pulse wave as it travels rapidly towards the distal end of the arteries.” (DeLaune & Ladner, Fundamentals of Nursing; 4th ed. P.505)Superficial peripheral pulses can be palpated over a muscle or bone.Pulse pressure is a measurement of the ratio of stroke volume to compliance of the arterial system (systolic BP minus diastolic BP)
8QuestionWhich one of the following pulse sites is located on the inside of the elbow?A. TemporalB. RadialC. FemoralD. Brachial
9Answer Answer: D. Brachial Rationale: The brachial pulse site is located on the inner elbow.The temporal site is located on the side of the head, the radial site is on the wrist, and the femoral site is located on the groin.
10Normal pulse rate NORMAL Adult: 60-100 BPM ATHLETES: may be slightly lower as in the 50’sMENWOMENWhen you have cardiovascular systems lecture, you will learn more complex interpretation of BP and Pulse
11Characteristics of the Pulse Pulse rateMeasured in beats per minuteBRADYCARDIATACHYCARDIAPULSE DEFICITPulse quality (amplitude)The quality of the pulse in terms of its fullnessPULSUS ALTERANS-A WEAK PULSE ALTERNATING WITH A STRONG ONEPULSUS PARADOXUS-DECREASE IN THE STRENGTH OF THE PULSE (& SYS BP) DURING INSPIRATION—IN ALT DIS STATES e.g. asthmaPulse rhythmPattern of the pulsations and the pauses between themNormally regularDYSRHTHMIA-REG-IRREG; IRREG-IRREG
12Methods of Assessing the Pulse Palpating peripheral arteriesAuscultating the apical pulse with a stethoscopeUsing a portable Doppler ultrasoundLISTEN AND COUNT THE APICAL PULSE IN ONE FULL MINUTECOUNT PERIPHERAL PULSES IN ONE FULL MINUTE ESPECIALLY WHEN IT IS IRREGULAR
14Assessing an Apical Pulse IndicationsPatient is receiving medications that alter heart rate and rhythmA peripheral pulse is difficult to assess accurately because it is irregular, feeble, or extremely rapidMethodCount the apical rate for one full minute by listening with a stethoscope over the apex of the heartMost reliable method for infants and small children; can be palpated with fingertips
16Physiology of Blood Pressure Force of the blood against arterial wallsTwo factors determine blood pressure: cardiac output and peripheral vascular resistance.
17Physiology of Blood Pressure Cardiac output is the volume of blood pumped by the heart in one minute. (stroke volume x heart rate)Peripheral vascular resistance is the force in the blood vessel that the ventricle must overcome to eject the blood from the heart.
18REVIEW-Physiology of Blood Pressure Force of the blood against arterial wallsTwo factors determine blood pressure: cardiac output and peripheral vascular resistance.Cardiac output is the volume of blood pumped by the heart in one minute. (stroke volume x heart rate)Peripheral vascular resistance is the force in the blood vessel that the ventricle must overcome to eject the blood from the heart.Resistance to blood flow is determined by the diameter of the blood vessel and blood viscosity.Controlled by a variety of mechanisms to maintain adequate tissue perfusion (brain, kidneys, cardiovascular system)
19Blood Pressure The force of the blood against arterial walls Systolic pressureThe highest point of pressure on arterial walls when the ventricles contractDiastolic pressureThe lowest pressure present on arterial walls during diastole is the diastolic pressure (Taylor, 2007).

21NORMAL & ABNORMAL BLOOD PRESSURE NORMAL BLOOD PRESSURE READINGS VARY WITH DIFFERENT AGE GROUPSNORMAL ADULT: <120 SYSTOLIC; <80 DIASTOLICPREHYPERTENSION: SYSTOLIC OR DIASTOLICHYPERTENSION STAGE 1: SYSTOLIC OR DIASTOLICHYPERTENSION STAGE 2: =OR >160 SYSTOLIC OR =OR >100 DIASTOLICHYPOTENSION: LOWER THAN NORMAL BP (80/40)

26CUFF SIZESPHYGMOMANOMETER CUFF SHOULD HAVE BLADDER WIDTH THAT IS AT LEAST 40% OF THE ARM CIRCUMFERENCE BETWEEN THE ACROMIAL PROCESS AND THE OLECRANON.THE LENGTH OF THE CUFF SHOULD BE AT LEAST 80% OF THE ARM CIRCUMFERENCE MIDWAY BETWEEN THE ACROMION AND THE OLECRANON

28TECHNIQUE IN MEASURING BLOOD PRESSURE, continued IF THE PATIENT IS IN A SITTING POSITIONHAVE PATIENT/CLIENT LEAN BACK IN THE CHAIR, SUPPORT HER BACKUNCROSS LEGSARM SHOULD BE AT LEVEL OF THE HEART PALM UPWARD
29TECHNIQUE IN MEASURING BLOOD PRESSURE, continued IF THE PATIENT IS IN A SUPINE POSITIONSUPPORT THE ARM WITH A PILLOW, AT THE LEVEL OF THE HEART, PALM UPWARD
30Proper Positioning for Blood Pressure Assessment
31TECHNIQUE IN MEASURING BLOOD PRESSURE, continued INFLATE THE CUFF WHILE CONTINUING TO PALPATE THE ARTERYThe point where the pulse disappears provides an estimate of the systolic pressure. To identify the first KOROTKOFF sound accurately, the cuff must be inflated 20-30mm above the point at which the pulse is no longer felt.DEFLATE THE CUFF AND WAIT ONE MINUTE
32TECHNIQUE IN MEASURING BLOOD PRESSURE, continued ASSUME A POSITION THAT IS NOT 3 FEET AWAY FROM THE PATIENTPLACE THE STETHOSCOPE EARPIECES IN YOUR EARSPLACE THE DIAPHRAGM OF THE STETHOSCOPE OVER THE BRACHIAL ARTERYPUMP THE PRESSURE 30 mm Hg ABOVE THE POINT AT WHICH THE FIRST SYSTOLIC WAS ESTIMATEDOPEN THE VALVE ON THE MANOMETER AND ALLOW THE AIR TO ESCAPE SLWLY (GAUGE DROP 2 T0 3 mm/sec)
33TECHNIQUE IN MEASURING BLOOD PRESSURE, continued NOTE THE POINT ON THE GAUGE AT WHICH THE FIRST FAINT, BUT CLEAR, SOUND APPEARS THAT SLOWLY INCREASES IN INTENSITY.NOTE THIS NUMBER AS THE SYSTOLIC PRESSURE.READ THE PRESSURE TO THE CLOSEST 2 mm HgDO NOT REINFLATE THE CUFF ONCE THE AIR IS BEING RELEASED TO CHECK THE SYSTOLIC READING
34TECHNIQUE IN MEASURING BLOOD PRESSURE, continued NOTE THE POINT AT WHICH THE SOUND COMPLETELY DISAPPEARS. THIS GENERALL CONSIDERED AS THE DIASTOLIC PRESSUREALLOW THE REMAINING AIR TO ESCAPE QUICKLYREPEAT ANY SUSPICIOUS READING, BUT WAIT AT LEAST ONE MINUTE.REMOVE CUFF REMOVE PPE.CLEAN STETHOSCOPE WITH ALCOHOL
35TECHNIQUE IN MEASURING BLOOD PRESSURE, continued RECORD THE FINDINGS ON THE PAPER, OR FLOWCHART OR ON COMPUTERIZED RECORDREPORT ABNORMAL FINDINGS TO THE APPROPRIATE PERSONIDENTIFY THE BP SITE, PATIENT POSITIONEXAMPLE:8/17/ BP TAKEN RIGHT ARM 120/80, SITING.
36Measuring Blood Pressure Blood pressure is measured in millimeters of mercury (mm Hg)Blood pressure is recorded as a fractionThe numerator is the systolic pressureThe denominator is the diastolic pressurePulse pressureThe difference between the systolic and diastolic pressureMAP: MEAN ARTERIAL PRESSURE (SYSTOLIC + TWICE THE DIASTOLIC DIVIDED BY THREE)
