Iv Flashcards
Isotonic
Equal osmotic pressure to normal body fluid
Cell stay same size
Hypotonic
Depressed osmotic pressure to normal body fluid
Cell increases in size
Hypertonic
Increased osmotic pressure to normal body fluid
Cell shrinks
Isotonic solutions
Equal concentration of solutes
No change in the size of the cell
Solution stays in the venous system, increasing the blood volume
Iso
0.9% normal saline
Fluid replacement
2/3 - 1/3
0.3% NS to 3.3% D5W combined
Long term hospital use
Ringers lactate
Fluid replacement
Electrolytes
Lifelines
D5W
PCPs do not use this
Becomes hypo in the veins
Med route
Micro drip
Smaller amount of fluid delivered with each drop
60 drops to 1ml
Delivers fluid and very precise amounts
Useful in children and adults require minimal amount
Macro drip
Used one large amount of fluid as needed
Larger opening allows for a bigger drop size
Typically delivers 10, 15or 20 drops per ml
Buretrol
Used a med amsistration
Antecubitol fossa
Ac vein
I’ve gauge sizes
24-12
Large bore for what kinds of med
Viscous med like 50% dextrose
pts in shock
14-16 large bores
Tunica intima
Inner layer
Allow fluid to flow smoothly
Tunica media
Middle layer
Provide support for the vessel
Also changes vessel diameter to regulate blood flow and blood pressure
Tunica externa
Outer layer
Provide basic structural support to the blood vessels
Putting a iv in at what degree
45 degree dropped down to 15 degree
Catheter, sheer
Occurs when part of the plastic breaks off inside the vein
Pryrogenic reaction
Foreign portions in bag
Parkland formula
4cc x body weight kg X %of burn
For 2 and 3 degree burns
Half the volume is given in the first eight hours
Second half of the volume is giving over the next 16 hours
TKVO
Approx 150ml/hr itls
Approx 30ml/hr ahS
Trauma/hypovolemic pt
500ml bolognese to a max of 2L
Or to maintain a Bp of 90 systolic
Map of 65
Or return of peripheral pulses
Crystalloids
Have small molecules and provide immediate fluid resucition
Collids
Have larger molecules, and provide volume expansion
Asthma boulous
The 500 cc and then at 250 Mantance drip to get rid of mucus
Iv target
Map of, 65
Return of peripheral pulses
systolic blood pressure, 90
Where do you put the IV in a cardiac patient?
Left side
Which side to a stroke patient
218 gauges in the AC right TKVO
