Cardiovascular Conditions pt. 1: Eval thru Telemetry Flashcards
what does the ability of the heart to pump depend on
automaticity excitability conductivity contractility rhythmicity
what pressure system is the R side of the heart
low pressure system
what pressure system is the L side of the heart
high pressure system
atrial systole
period of atrial emptying
includes atrial kick
atrial diastole
period of atrial filling
ventricular systole
period of ventricular contraction
1st reading of BP
ventricular diastole
period of ventricular filling
2nd reading of BP
ejection fraction is normally at what %
60
what are the 3 things included in the perfusion triangle
heart
blood vessels
blood
what is the pump function in the perfusion triangle
heart
damage to the heart by disease or injury, it cannot move blood adequately to support perfusion
what is the container function in the perfusion triangle
blood vessels
if all vessels dilate at once, the normal amount of blood volume is not enough to fill the system and provide adequate perfusion to the body
what is the content function in the perfusion triangle
blood
if blood or plasma is lost, the volume in the container is not enough to support the perfusion needs of the body
what is a major dysfunction of the pump fxn
CHF
what is a major dysfunction of the container fxn
HTN
what is a major dysfunction of the container fxn
sustained bleeding/hemmorrhage
information about cardiac dysfunction to take down during a cardiac eval
- presence of chest pain
- location, quality, characteristics of pain
- angina
- previous MI
- meds
- hx of cardiac conditions
- syncope, dizziness
- cardiac risk factors
if a pt has any risk factors for a cardiac condition what should vthe physical therapist do
provide education on how to manage those risk factors
what is a key component of a cardiac eval
the observation
what does the observation portion of a cardiac eval include
skin color/tone diaphoresis edema RR signs of trauma jugular distention
what are you checking with palpation
pulse for circulation
HR
rhythm
pitting edema
how do you measure irregular HR
use care with pressure during pulse palpation
when do you count HR for a full 60secs
if <60 or >100
1+ on edema scale
trace
slight
barely perceptiple depression
2+ on edema scale
mild
0 - 0.6cm
easily identified depression
rebounds in 15secs
3+ on edema scale
moderate
0.6-1.3cm
EID
rebound in 15-30secs
4+ on edema scale
severe
1.3-2.5
EID
rebound in >30secs
telemetry
allows for continuous monitoring of HR and rhythm along with RR
five color coded leads placed on chest: electrical signals converted to radio waves and allow for central monitoring at nurse’s station
what is the green on telemetry
HR
what is the red on telemetry
BP from an arterial line
measuring pressure in real time
what is the purple on telemetry
also BP from a cuff
measuring last 5 readings
what is the yellow on telemetry
pulmonary artery pressure (PAP) via a swan ganz catheter
what is the blue on telemetry
oxygen saturation
what is the white on telemetry
RR
