perfusion exam 3 208

perfusion

Process of delivering oxygen rich blood to the bodies tissues and organs thru the circular system

what can the pump be compromised by

heart failure, myocardial infarction, arrythmia

Hypertension and vascular disease

impairs vessels ability to regulate blood flow

what can alter balance of fluid

Dehydration, hemorrhage and fluid overload

heart failure

heart cant pump blood effetely leading to poor circulation and fluid buildup in tissue

Myocardial infraction (heart attack)

Damage to the heart muscle from a blocked artery reduces ability to pump blood

arrthymia

abnormal heart rthymn can cause inefficient pumping and reduce blood flow to body

Atherosclerosis

fatty plaques build up narrowing and contracting blood flow

Hypertension

damages vessels walls and leads to narrowed or elastic arteries

shock(septic anaphylactic) leads to

severe vasodilation and can cause poor perfusion

diabetes cause

sugar can sheer the vessel walls

dehydration cause

reduce fluid levels lowering blood pressure and volume

hypervolemia

fluid retention and edema

imbalance in fluid can lead to

dehydration

fluid overload

electrolyte disturbances

what should the body not fluctuate more than

.5 lb

.2 kg

icf electrolytes

K

mg

phosphate

what are the ICF electrolytes essential for

muscle function nerve signal and energy production

what are the ecf electrolytes

na, cl, bicarbonate

ecf electrolytes are essential for

fluid balance, acid base balance, and blood pressure

different divisions in ecf

interstial

plasma

transcellular

who has less body water

women and obese

health person total body water

50-60%

infants are more prone to

dehydration

what is the primary solvent in body

fluid (water)

what is crucial for oncotic pressure

blood plasma

what is crucial for keeping blood pressure at healthy levels

blood plasma

interstitial fluid

surround cells of tissues

plasma

fluid portion of blood

transcellular

synovial fluid, CSF, digestive secretions

what is a solvent essential for

reg body temp, lubricate tissues, support cellular function

solute help regulate

osmotic pressure

osmotic pressure

movement of water between fluid compartments

osmosis moves from

low to high

what keeps balance of icf and ecf

solutes

solutes move thru

active transport and diffusion

fluid move thru

osmosis and capillary filtration

osmolality

concentration of solutes in a solution

osmolarity

number of solute per liter of solution

diffusion

high to low concentration

filtration

process of fluid and solute move across capillary walls due to pressure differences

liver disease

doesn’t make albumin

kidney disease

doesnt make protein for urine

venous end

oncotic pressure

arterial end

hydrostatic pressure

increase hydrostatic pressure

fluid overload

decrease oncotic pressure

low albumin

injury or inflammation can cause

leaky capillaries

capillary filtration maintain

tissue hydration and nutrient delivery

na/k pump is

3 na in

2 k in

Electrolyte imbalance can lead to

muscle weakness cardiac arrythmia and neurological dysfunction

diuretics does what to solutes

make you pee them out

potassium control

heart

na control

brain

ca control

muscle

mg control

heart and muscles
