Patho and s/s of Left sided heart failure.
Give this one a try later!
, Patho of HF -
- When the heart no longer functions as a pump.
Left sided Heart Failure -
- HOW IT SHOULD WORK - Left side of the heart receives oxygenated
blood from the lungs and delivers that blood to the body.
- If this side LEFT side fails - no or not enough oxygenated blood gets to
the body (decrease blood to the body.)
- If blood doesn't move out into the body, it starts to back up into the
lungs. Fluid build up in the lungs - Pulmonary Edema! More fluid in lungs
and it's hard for gases to exchange.
- Brain and Kidneys try to compensate for lack of O2. RAAS system
activates (raise BP, hold onto urine/fluids to increase fluid volume)
- Heart may compensate too - beat harder, faster (tachy), Skip a bit (AFib)
s/s - Tired, Fatigued, Urine output decreases, decrease pulses, decreased
perfusion, crackles in the lungs, weight gain, irregular heart beat, difficult
breathing (dysnea).
acute coronary syndrome (ACS)
Give this one a try later!
sudden symptoms of insufficient blood supply to the heart indicating
unstable angina or acute MI
What is a true aneurysm?
Give this one a try later!
involves all 3 layers of arterial wall
, Cardiac Output (CO)
Give this one a try later!
measurement of the amount of blood ejected per minute from either
ventricle of the heart
echocardiogram
Give this one a try later!
ultrasound of the heart
What is pericardial effusion?
Give this one a try later!
An accumulation of fluid in the pericardial cavity
What is the main mechanism for blood pressure control?
Give this one a try later!
Renal mechanisms are the most important in blood pressure control
