Plumozyme dosage???
MUCOKINETIC -
2.5mg in a 2.5 ml solution
once a day - Plumozyme precaution (2)
- refrigerate after opening and keep in low light
- WHAT CAN BE USED FOR AN ACETOMINAPHEN OVER DOSE??
- MUCOMYST
- Amiloride
- diuretic and sodium channel blocker
- how much mucus is produced in a day
- 100 ml/day most reabsorbed about 10 ml reaches the pharynx each day
- what type of solutions will stimulate mucus production
- hypertonic and hypotonic solutions
-
Surface Tension
fyi measured in dynes - a force at the liquid gas interface which tends to hold liquid surfaces intact
- surfactant
- surface agent that lowers surface tension
- as surface tension decreases distending pressure increases or decreases??
- decreases
- pulmonary edema
- when fluid crosses from the pulmonary vasculature into the extravascular space and into the alveous. It is then churned into a froth.
- where is sufactant produced??
- type II alveolar cells
- what happens during infant respiratory distress syndrome
- an immature lung does not produce surfactant
-
how is surfactant administered
for infant respiratory distress syndrome - thru and ET tube at birth with the first breaths of within 12 hrs followed by ventilation and turning the baby to increase distribution
- 3 ways surfactant can be obtained?
-
human lung
bovine
and synthetic - artifical surfactant is called???
- Trade Exosurf Generic colfosceril palmitate
- what is bovine surfactant called?
-
Trade Survanta
Generic Beractant - hazards of surfactant therapy
-
lrg volumes of surfactant can lead to aw obstruction,desaturation and bradycardia
improvement in compliance can lead to overventilation, excessive volume deliver and over oxygenation - 3 ypes of hormones produced by the adrenal cortex
- glucocorticoids,mineral corticoids and sex hormones
- what do glucocorticoids,mineral corticoids and sex hormones regulate?
-
glucocorticoids regulates metabolic function and rate
mineral corticoids body water and electrolytes and sex hormones androgena and estrogens - what system do corticosteroids act within ?
- endocrine system
- what regulates steroid production in the body??
- hypothalmic pituitary axis
- 3 side effects of gluco and mineralcorticoids
- muscle wasting, steroid diabetes and adrenal suppression
- why is alternate day administration of steroids good?
- mimics night and day body rhythmic and allows body to produce cortisone on the off days
- why do steroids work
-
constricts microvasculature decreasing leakage,
inhibits late response,
increases beta receptor density on the cell wall,
inhibits uptake 2 mechanism, increasing circulating endogenous catecholamines,
may activate adenyl cyclase, inhibit phospholipase and block arachidonic acids,
decrease leukocytes,
decrease neutrophis demargination accumulation on capillary walls thus increase number of circulating neutophils - why are steroids given after transplants
- used as immunosuppressants to decrease chance of rejection also depress lymphocytes increasing the risk of develping infection
- release of chemical mediators from mast cell cause
- smooth muscle spasm, mucus secretion,mucosal swelling from increased vasular permabliity (leaky cells),increase eos & neutophils that shed in AW's leaving cellular debris,goblet cell hyperplasia resulting in mucus plugging and late phase response

-
WHAT DO THE FOLLOWING IMMUNOGLOBULINS DO??

-
WHAT DO THE FOLLOWING IMMUNOGLOBULINS DO??
IgE, - causes asthma and allergic reaction
-
WHAT DO THE FOLLOWING IMMUNOGLOBULINS DO??

-
what does cromolyn sodium do??
prophylactic treatment - it's a mast cell inhibitor, mast cell woin't spill out
- what does cromolyn sodium NOT do??
- act on mediators themselves,operates thru cyclic amp sys,effect alpha or beta receptors, prevent IGE to mast cell
