Essentials of Healthcare

Slide 2

The pressure of the blood felt against the wall of an artery as the heart beats Felt most easily in arteries, especially those that can be gently pressed against a bone The pulse lets us know how the cardiovascular system is meeting the bodys needs

Slide 3

Radial pulse is most commonly used and is found in the inner aspect of the wrist You must note 3 things when checking a pulse Rate or speed Rhythm (regular or irregular) Volume (strong, weak, thready, bounding) You must record date and time pulse was taken in addition to the above findings

Slide 4

Pulse rate is measured as the number of beats per minute Counted for one full minute and recorded as a number Followed by the abbreviation bpm (beats per minute) Varies by individual age, sex, body size and illness

Slide 5

Normal Ranges Adult 60-80 Children 7+ 70-100 Children 1-7 80-100 Infants 120-160 You must report Tachycardia (over 100 beats per minute) Bradycardia (below 60 beats per minute) Irregularities in rhythm or volume

Slide 6

May be affected by many things illness Emotions Age Exercise Elevated temperature Drugs position

Slide 7

Measured by counting the heart contractions Left side of chest Between 5/6 ribs Just below left nipple Under left breast in a female Listen for lub dub The sound you hear are the heart valves opening and closing

Slide 8

Always count for one full minute Who needs an apical pulse checked? Whenever pulse deficits exists or is suspected Before meds that change heart rate or rhythm On any child 12 months or younger Can be hard to feel/count a faster pulse Whenever radial pulse if irregular or if you are uncertain of the accuracy of the radial pulse On any child in which it is difficult to get a radial pulse

Slide 9

This occurs when the heart is too weak and does not pump enough blood to produce a pulse or when the heart beats too fast, not allowing the heart to fill with blood between beats. The apical rate would be greater than the radial rate. How do you check a pulse deficit? One person checks apical rate while another checks radial rate. If the rates are different, a pulse deficit exists.

Slide 10

Measures the force of blood against the artery walls Blood pressure is measured in mmHg (millimeters of mercury) Systole (systolic reading)-the force of blood against the artery walls during ventricular contraction-working pressure Diastole (diastolic reading)-the constant pressure in the walls of the arteries-resting pressure

Slide 11

What elevates the BP? Exercise Eating Stimulants Stress, fear, anxiety Arteriosclerosis, high cholesterol, diabetes Pain Obesity

Slide 12

What lowers BP? Rest Depressants Weight loss Shock Grief Dehydrations Diuretics

Slide 13

What does the equipment look like? Electronic sphygmomanometers Aneroid sphygmomanometer Mercury sphygmomanometers Stethoscope

Slide 14

Cuff is placed directly over the brachial artery (1 inch above the antecubital space) Systolic pressure is the first regular sound you hear Diastolic pressure will be the change or last sound you hear Pulse pressure will give you information on the condition of the arteries in the body The difference between the systolic and diastolic pressure

Slide 15

Normal Ranges-recorded as a fraction Average resting pressure 120/80 Normal Systolic Pressure Range 100-140 Normal Diastolic Pressure Range 60-90 Hypertension-pressure above 140/90 Hypotension-pressure below 100/60 The systolic and diastolic values should be looked at separately to determine normal

Slide 16

Can you use any arm to check BP? No. When would you not use an arm? If it has an IV line or other device inserted Is being treated for burn, fracture, etc Has dialysis access device Is on the same side as a recent mastectomy or other surgical procedure If the arm is paralyzed, injured or has edema If the arm has a pulse oximeter on it

Slide 17

Inaccurate or erroneous blood pressure readings are due to: Wrong size cuff Improperly wrapped cuff Incorrect positioning of the arm Not using the same arm each time Not having the gauge at eye level Deflating the cuff too slowly Mistaking an auscultatory gap for the diastolic pressure

Slide 18

Make sure the gauge is at eye level It should not be tilted The gauge Each small line represents 2mm Hg Each large line represents 10mm Hg

Slide 19

What do I report? If you were unable to get the reading If it is higher than a previous reading If it is lower that a previous reading If the site where the BP was taken was other than the brachial artery The position of the patient (sitting, standing, lying down)

Slide 20

Orthostatic, or postural, hypotension occurs when there is a sudden drop in both systolic and diastolic pressures when an individual moves from a lying to a sitting or standing position Your blood vessels cant compensate quickly enough to the change in position Dizziness, lightheadedness and blurred vision may happen Patients may need orthostatic blood pressures taken to see if this condition is occurring We do them lying, sitting then standing to determine if there is a drop

Slide 21

Electronic blood pressure monitors are not for everyone Do not use on those with: Extreme hypertension or hypotension Very rapid heart rates Excessive body movements or tremors Irregular heart rhythms or dysrhythmias

Slide 22

Practice measuring pulse and blood pressure following your check off sheets
