HR & blood pressure measurement Flashcards
heart rate
index + middle fingers on inside of wrist lateral to flexor muscles / neck beside trachea / dorsal foot lateral to EHL, distal to navicular
count beats per min / x2 after 30sec
check for adverse effects
blood pressure
patient positioned with arm at level of heart
sphygmomanometer cuff around upper arm, arrow pointing at brachial artery, lower edge is inch below elbow, attach pressure gauge, close valve, pump air into cuff to 150mmHg, stethoscope over brachial artery/medial elbow, slightly open valve, when 1st pulse sound is heard read systolic pressure, continue releasing air, at no pulse sound read diastolic pressure
record
repeat x3, cuff deflates fully + 30sec in between
precautions
vomiting, nausea, vertigo
open wounds
lymphadema
arm after breast cancer
purpose
HR
indicates general fitness & wellbeing, exercise intensity needed in sport programmes
tachycardia - high, from anxiety
bradycardia - low, from hypothyroidism
BP
screening for hypertension (not enough blood to organs/angina), assess suitability for sport/occupations, CV status, medical procedures risk
principles
rests for 10mins prior
not anxious, no caffeine, no exercise
comfortably seated, elbow at heart level
no tight clothing, arm exposed
structures
Measures the number of times you heart completes a full cycle and pumps blood around the body, bpm.
radial artery in wrist
Measures the amount of pressure exerted on the walls of the arteries as the blood moves through them, mmHg.
use a stethoscope on the brachial artery
how to know if normal
know average HR/BP for age
60-100bpm
90/60mmHg - 120/80mmHg
may vary dependent on age, stress, fitness, medication
note any irregularities in strength/rhythm of HR
