How much blood is pumped from the heart to the arterial circulation in 1 min is the carida output (CO)
CO= heart rate (HR) X stroke volume (SV)
define heart rate
number of contractons of the heart/minute
define Stroke Volume
amount of blood that is pumped out of the heart with each contraction
what part of the nervous system controls the heart rate?
autonomic nervous system
what part of the nervous system lowers the heart rate?
parasympathetic nervous system
what part of the nervous system raises the heart rate?
sympathetic nervous system
how to measure the strength of a pulse?
0= absent, unable to palpate
1+= diminished, weaker than expected
2+= brisk, expected
4+= full volume, bounding
what is the normal pulse rate for the healthy adult client?
60-100 Mins at rest
What is tachycardia?
what is bradycardia?
an irregular rhythm of the heart that frequently is noted as an irregular radial pulse
what is a pulse deficit?
occurs when the apical rate is greater than the radial rate. In the case of a dysrhythmia, the heart may contract ineffectively resulting in a beat being heard at the apical site, but a pulsation not being felt at the radial pulse point
what is the normal pulse rate for an infant?
what is the normal pulse rate for a 12-14 year old?
