practical 2: blood pressure and cardiac rate Flashcards
(26 cards)
how are contraction and relaxation of the heart measured
the pulse and blood pressure
average blood pressure for human
120/80 (systole/ diastole)
how does blood pressure rate vary
in relation of size and age of the individual as well as peripheral resistance of the systematic circulatory system
ventricular systole produces a wave of pressure in arteries called
pulse
where can the pulse be felt
where an artery lies near the surface of the skin or on the surface of a bone
how do pulse rates vary
chenges in temp, stressful conditions, the time of day, etc
what is normal pulse rate
60-100 bpm
beating of heart makes certain sounds that can be heard thru
stethoscope
stethoscope amplifies well defined sounds described as
lubb-dubb
splitting of the heart sound may be more evident during
inhalation
the first heart sound may be split into 2 sounds because of
separate closure of the right and left av valves
second heart sound may be split into 2 components due to seperate closure of
right and left semilunar valves
— is routinely measured in an indirect manner by the use of the —
arterial blood pressure; sphygmomanometer
what are the sounds called that are produced during the measure of blood pressure
sounds of korotkoff
good physical fitness is associated with
-slower rate of increase in cardiac rate with exercise
-a faster return to the resting cardiac rate after exercise
what is the ideal return rate after exercise
2 mins
involves muscular development and ability of the cardiovascular system to adapt to sudden changes in demand
physical fitness
evaluates the cardiovascular physical fitness of an individual
the schneider test
A rare disorder that causes the body to make too much urine
Antidiuretic hormone is not secreted adequately, or the kidney is resistant to its effect
diabetes insipidus
A dilation of a common carotid artery; involved in regulation of systemic blood pressure.
carotid sinus
The cuff pressure at which the sound becomes muffled
diastolic pressure
Which is more accurate, counting the pulse for a full minute or counting the pulse for a 30 second interval and multiplying by 2?
full minute
Why would one method of measuring pulse be preferred over the other?
The method where you count the pulse for 30 seconds and multiply by 2 is faster than counting for a full minute, so that may be a reason it is preferred over the other.
Which artery is occluded when taking a patients BP?
brachial artery
