Cardio Flashcards
Unoxygenated blood comes from
Heart to lungs
Oxygenated blood comes from
Lungs to heart
Cardiac output
Amount of blood pumped by each ventricle in 1 min
Heart rate is controlled by
Autonomic nervous system
Stroke volume is affected by
Amount of blood pushed with each contraction
- preload
- contractility
After,old
Preload
What is left in the chamber at the end of a contraction
After load
What is the pressure / force the heart needs to contract
What happens when heart failure occurs?
Kidneys compensate
- producing aldosterone
Pulse pressure
Difference between systolic and dystolic pressure
- 40-60
Mean arterial pressure
Average pressure with arterial system that is felt by an organ
Map= systolic pressure + (2) dystolic pressure /3
Goal for cardiovascular system
Recognize early cues and interview before patient declines
What is considered an orthostatic blood pressure
Systolic dropping more then 20
Where do you listen for heart sounds
Think : ape to man
Aortic
Pulmonic
Erbs point
Tricuspid
Mitral
During auscultation, what are you listening for
S1 & s2
Lub dub
- anything different = s3/ s4
What do you record if you hear an abnormal sound when auscultating
Timing
Location
Position of patient
