cardiac Flashcards
what are vital signs?
temperature
pulse
respiratory rate
blood pressure
oxygen saturation
what is a pulse?
a heartbeat as 2 parts. Lubb and Dubb
explain lubb and dubb
lubb= upper chambers of the heart contract
dubb= lower chambers of the heart contract
the blood from each contraction produces what?
a bulge artery and then pulse and then a heartbeat
how to measure pulse rate
wash hands, locate the pulse, choose appropriate site and note : rate, rythm, quality
true or false: if pulse is regular, count for 60seconds
and if its irregular count for 30 seconds and double it
false
What is the normal adult pulse?
60-100 bpm
what are the appropriate sites
Carotide, brachial, radial, ulnar, femoral, posterior tibial, popiteal
what is apical pulse?
point of maximal impulse or the true pulse
how do we locate apical pulse?
- ascultated w stethoscopes
- apex located on the left side between 5th and 6th ribs, mid clavicular line
- below left nipple (MEN) and below left breast (female)
- hear for the LUBB and DUBB
- louder sound of lubb is counted
- do for 1 min
define pulse deficit
when the heart is too weak to send blood to the peripheral arteries : abnormal speed/ rythmn& circulatory problems
- difference between apical and radial
ex: apical = 110 and radial= 80
110-80=30
what is abnormal heart rythm
arrythmia
name of pulse rate below 60 bpm (athlete,cold,emotions)
bradycardia
name of pulse rate higher 100 bpm (exercise,fever, pain)
tachycardia
explain blood pressure
force created by the blood pushing agaisnt the artery walls
what do you need to do blood pressure
cuff blood pressure, right size cuff, stetoscope
what is the procedure of blood pressure
-palpate radial or brachial artery
-note reading at which pulse disappears
-continue to inflate 30mmHg
- deflate cuff slowly and note when pulse is felt/disappears
- complete and wait for 30 minutes
explain auscultatory
sounds may disappear all together for a short period of time
procedure of ascultatory/korotkoff
phase 1: first appearance of faint and clear tapping sounds that gradually increase for 2 consecutive beats (systolic)
phase 2: sounds soften and acquire a swishing quality
phase 3: return of sharper sounds (crisper to regain)
phase 4: muffling sounds: becomes soft and blowing in quality
phase 5: all sounds disappear completely (diastolic pressure)
what is blood pressure normal adult
BP= 120/80
what is hypertension normal adult
140-159/90-99
what is hypotension adult normal
< 90 systolic
does the position changes the blood pressure?
yes
when does blood pressure drops
within 3 min of standing
what are the symptoms of orthostatic hypotension
dizzy, faint, blurred vision
major cause for changes in blood pressure measurements
-age: increases with age
-ethnicity: south asian, black = higher BP
-gender: minor variances
-daily variation: lower during sleep
-medications: cardiac meds
-others: smoking
