Final Exam Flashcards
What is Cardiac Output?
The amount of blood that is pumped out of the heart in a minute
What is normal Cardiac Output?
4-6 L at rest
What is Stroke Volume?
The amount of blood pumped by the heart with each beat.
What is normal Stroke Volume?
2.4 oz (71 ml)of blood per beat
What is Ejection Fraction
It’s the ratio of the volume of blood ejected from the L ventricle per beat to the volume of blood in the L ventricle after filling
(diastole)
What is the normal Ejection Fraction
.6-.75
What does the P wave of an EKG represent?
Arterial Depolarization
What does the QRS portion of an EKG represent?
Ventricle Depolarization
What does the T wave of an EKG represent?
Ventricles Repolarization
What does the ST segment of an EKG represent?
Ventricles initiate repolarization
What is a dip in the ST segment of an EKG indicative of?
A CAD
What is a spike in the ST segment of an EKG indicative of?
An acute MI
What are the steps of Normal Conduction of the Heart?
- SA Node
- AV Node
- Bundle of His
- Branches
- Purkinje Fibers
What is the Karvonen’s Formula?
60%-80% x (HR max - HR rest) + HR rest = Target HR
How should you calculate a Max HR if no stress test has been performed?
220-age
What should the THR for a post MI patient be if no stress test was done?
Resting HR + 20 or <120 bpm
What should the THR for a post CABG patient be if no stress test was done?
Resting HR + 30
What should the normal response of HR and RR be if O2 drops?
They should increase
For every MET, how much should HR and BP rise?
8-12 bpm/mmHg
What are typical exercise METS for cardiac inpatient patients?
2-3
What is the goal RPE score for an inpatient cardiac patient being exercised?
11-13/20
What does a typical exercise prescription for a cardiac patient in acute rehab look like?
-10 min warm up at approximately 1.5 METS
-20-30 min aerobic exercise at THR (1.5-3 METS)
-5-10 min cool down till patient reaches resting HR
What is the Questionnaire used to determine if it is safe for a patient to begin an aggressive exercise regimen?
PAR-Q and You
What is the scoring for the Tinetti Assessment test like?
-16 possible points for Balance
-12 possible points for Gait
-28 total possible points
-The more points, the more functional the patient is
