Denominator = diastolic blood pressure - usually less than 90 mm Hg
99
What are factors contributing to blood pressure?
Cardiac output - BP increases during exercise
Peripheral vascular resistance - circulatory disorders increase BP
Circulating blood volume - increase in volume increases BP
Viscocity - thicker blood will increase pressure in blood vessels
Elasticity of vessel walls - increase in stiffness increases BP
100
How is blood pressure measured?
Using sphygmomanometer & stethescope
101
What is the measurement of the width of the cuff?
⅔ of the lenght of the upper arm, 40% of the circumference of the upper arm, or more than 20% of the diameter of the upper arm
102
What should the patient do before taking blood pressure?
Be sure the patient is calm and relaxed and has not smoked, exercised for 30 mins prior to measurement - allow patient to rest for at least 5 mins before assesing
103
How shoudl he arm be supported when taking BP?
Patient maybe supine or sitting
Support the bare arm aat heart level with palm upward, supported on a table, feet flat on the floor and the back supported
Legs should not be crossed
104
How do you estimate the systolic blood pressure (SBP)?
Palpate the brachial artery above the antecubital fossa and medial to the bicep tendon
Centre the deflated cuff ~2.5 cm above the antecubittal crease
Line up the arrow on the cuff with the brachial artery
Estimate the SBP by palpating the radial rteyr and inflating the cuff until the pulsation dissapears
Squeeze the bulb to pump air into the bladder
Continue feeling the pulse, and identify when it disappears
Pump the cuff to 30 mmHG above where the pulse stopped
Slowly open the valve by turning it toward you to deflate the cuff
Feel fo the pulse - noting the number when the pulsation is palpable again - then quickly deflate the cuff completely =gives you the estimated SBP
105
How do you find the korotkoff sounds?
Wait 15-30 seconds before reinflating the cuff to allow trapped blood in the veins to dissipate
Position the earpieces of the stethoscope in your ears - place the diaphragm or bell of the stethoscope over the brachial artery
You will ot heat he tapping of the pulse until the cuff is inflated - inflating the BP cuff alters the flow of blood through artery which generates korotkoff sounds
Quickly inflate the cuff to 30 mmHg aboe the estimated SBP
Then deflate cuff slowly~2mm Hg while listening for pulse sounds (korotkoff sounds)
The korotkoff (I)coincides with the patient’s SBP
Korotkoff (IV) is the last pulse sound
Korotkoff (V) is when the pulse dissappears - used to define the DBP
106
What is auscultatory gap?
Period in which there are no Korotkofff sounds during auscultation - estimating the SBP will prevent missing this gap
The gap occurs between the first and second korotkoff sounds
107
What is the pulse pressure?
The difference between the SBP and the DBP = reflects the stroke volume
Usually ~40 mmHG
108
What is the mean arterial pressure?
Calculated by adding ⅓ of the SBP and ⅔ of the DBP
Usually around 60 mmHG needed for tissue perfusion
109
what is a sign?
measurable and objective (perceived by the observer)
110
what is the purpose of evaluation?
make judgement about the patient's progress, analyze the effectiveness of nursing care - monitor the quality of care
