Physical Exam (2)- Cardio Flashcards
what does the capillary bed join
arterial and venous systems
what is there b/w the arterial and venous ends of the system
normal balance
purpose of capillary refill time
determine the time is takes the capillary bed to fill
after it is occluded by pressure
what does the capillary refill time indicate
status of the system
technique of capillary refill time
blanch the nail bed w/ sustained pressure of several seconds on a toenail or fingernail
release the pressure
observed the time elapsed before the anil regains its full color
interpretation of capillary refill time if the system is intact
refill occurs in < 2 seconds
interpretation of capillary refill time if the system is compromised
refill will take longer than 2 seconds
is capillary refill time a specific test
no
may suggest a problem that doesn’t exist
what may alter the results of a capillary refill test
environmental influences
even a small change in room temp will prolong refill time
how should capillary refill times be used
cautiously in making clinical judgements
what is apart of any CV eval
inspecting the extremities for edema
purpose of checking for edema
screen for changes in the orthostatic pressure system
screen for venous insufficiency
venous insufficiency
deep vein obstruction
venous valvular incompetence
technique for checking edema
observe for any unusual contours of the legs
press index finger over the bony prominence of the tibia or medial malleolus for several seconds
measure severity
how do we measure severity of edema
how deep the index finger goes into the area
how long it takes for distortion to disappear
