Lecture 18: Tests Flashcards
What is a non-invasive assessment?
An observation indicating an impairment of cardiac function is decreased level of consciousness
How does Mucus Membrane Color help with assessment?
The color is a reflection of hemoglobin saturation in the capillary blood
If Cardiac function is ______, pulse will be affected.
impaired
What is “Auscultation of Heart Sounds?”
Auditory examination of the heart.
- Done with a stethoscope over the valve, chamber or great vessel
What can Vectocardiogram assist in finding?
1) precisely locate the site of myocardial infarction
2) diagnose conduction defects
3) diagnose chamber hypotrophy
On a vectocardiogram, where are they placed?
fiver over the pericardium
one on the left leg
one in the back of neck
What is Pulse Tracing?
Pulsation described by the flow of blood through the artery during CC
can be drawn as a waveform potting pressure against time
What is an Echocardiogram?
ultrasonic sound waves that generate and direct into the cardiac structures and reflect waves at different angles and lengths according to structure and density
What is a Doppler Study?
Made by using a handheld microscope placed on the skin over a lubricating gel
What does a Chest X-ray show?
examination of the size and contour of the heart and related structures are visualized
What is an invasive assessment of function?
Greater risk of the individual study
X-ray with barium shows a cardiac silhouette shows a enhanced image than a single chest x-ray alone.
T/F
True
Cardiac Cauterization
For a right-heart cath, the cath is placed in the _____ or _____ artery
Brachial or Femoral
Cardiac Cauterization
For a left-heart cath, the cath is commonly placed in the ____ artery
Femoral
Once the cath is placed and guided into the atrium:
- pressures are recorded
- blood samples are obtained to examine oxygen content
- contrast medium is injected to visualized chamber function and valve patency
