electrocardiogram
aKA- EKG / ECG
records electrical impulses of heart (rate/rythm/injury)
holter monitor
ekg monitor over 24 hours
zio patch
same function of holter moniotor, used more today than holter
chemical stress
records eletrical actiivty after given drugs that increase cardiac workload- no excercise invovled
V-Q scan
checks for ventilation/ perfusion in lungs; examine in response to inflammation
CRP (c-reactive protein)
a protein in blood that increasess in response to inflammation
lumbar puncture
POST-OP
- maintain flat bedrest 6-8 hrs as ordered by hCP
- encourage fluids
- monitor puncture site
- monitor movement, sensation, and presence of headache
