cardiovascular Flashcards
cardiomyopathy
acquired or inherited disease of the heart muscle
difficulty pumping blood effectively
stiffen, enlarge or thicken
symptoms: sob, fatigue, swelling, dizziness, fainting, arrythmias, chest pain
shock
sudden drop in blood flow throughout the body
oxygen deprivation to organs and tissues
buildup of waste products
cardiac output
how much blood your heart can pump in a minute
blood pressure
force of blood inside arteries
multiorgan failure
two or more organ systems are not working correctly
subsequent to an acute injury or illness
acute renal failure (ARF)/acute kidney injury (AKI)
sudden and often temporary loss of kidney function
kidneys suddenly become unable to filter waste products from the blood - dangerous accumulation of waste
acute respiratory distress syndrome (ARDS)
non-cardiogenic pulmonary oedema and diffuse lung inflammation syndrome
typically presents with dyspnoea and hypoxaemia
progresses to resp failure
acute onset
bilateral opacities on chest xray/unexplained consolidations on ultrasound
disseminated intravascular coagulation
widespread hypercoagulable state
causes clotting and compromised blood flow
can result in MOF
Solute concentration ICF vs ECF
should be equal despite diff solutes being present in each compartment
290 mOsm
Afterload
pressure created by force of the contraction after blood is pumped to aorta
autoregulation
body adjusts BP to meet requirements
Cardiac output
amount of blood pushed out of left ventricle
contractility
force exerted by myocardium to push blood from ventricles
preload
stretching of muscles in ventricles as they fill with blood
stroke volume
volume of blood in a single beat
aneurysm
dialation in arterial wall which can weaken blood vessel
arteriosclerosis
hardening of stiffening of arteries
embolism
blockage in the blood vessel
atherosclerosis
build up of plaque in blood vessel
embolus
piece of material in travelling through blood stream that can cause occlusion
thrombosis
formation of presence of blood clot in a blood vessel
cor pulmonale
abnormal enlargement of the right side of the heart
cause by disease in lungs/pulmonary system
epistaxis
nose bleed
haemoptysis
coughing up blood
