Hemodynamics
the study of the movement of blood throughout the circulatory
system, along with the regulatory mechanisms and driving forces
involved
Two primary functions of the circulatory system
deliver oxygen, nutrients, hormones, electrolytes, and other
essentials to the cells, remove carbon dioxide and metabolic waste
from the cells (also helps fight infection)
Arteries
Do not stretch very easily, large increase in pressure causes small
increase in diameter
Veins
Stretch easily, small increase in pressure causes large increase in
diameter
Formula for cardiac output
HRxSV
Formula for Arterial pressure
PRxCO
,Nephron
Basic functional unit of the kidney
Three basic functions of the kidneys
Cleansing of ECF and maintenance of ECF volume and composition,
Maintenance of acid-base balance, excretion of metabolic wastes and
foreign substances
Diuretic Beers Criteria
Use with caution in 65 years or older due to the potential to
exacerbate SIADH or hyponatremia, monitor sodium concentration
closely
Unsafe to use diuretics in
Pregnant women, can cause maternal death, abortion, fetal
reabsorption
Safe to use diuretics
Small doses with pediatric patients
Furosemide works in the
Ascending limb of the loop of Henle
Furosemide brand name
Lasix
Furosemide MOA
Produces profound diuresis
Blocks reabsorption of sodium and chloride, preventing reabsorption
of water
Furosemide Use
Used when rapid or massive mobilization of fluid is required
- pulmonary edema from CHF
- edema from heart, liver, kidney that has not responded to other
medications
- HTN
Furosemide is especially useful in
, Especially useful in patients with severe renal impairment because it
can promote diuresis when GFR and renal blood flow are low
Furosemide can be combined with
Can be combined with a thiazide diuretic
Furosemide starts working
starts working in 60 minutes and lasts 8 hours
Furosemide goal
goal is to decrease edema and treat HTN
Furosemide caution
Use with caution with CV disease, renal impairment, DM, Gout,
Pregnancy, Ototoxic drugs, NSAIDS, antihypertensives
Furosemide is a k...
K wasting diuretic
Hypokalemia can cause
can cause fatal dysrhythmia
Hypokalemia value
Less than 3.5mEq/L
Furosemide adverse effects
adverse effects include hyponatremia, hypochloremia, hypotension,
dehydration, hypokalemia, hyperglycemia, hyperuricemia, increase in
LDL and triglycerides, decrease in HDL, ototoxicity
Signs of dehydration
signs include dry mouth, unusual thirst, oliguria
if dehydration or hypotension occurs with furosemide
discontinue furosemide if this occurs
Furosemide patient education
