plaster
Kind of needles cannula:
Intra CathButterfly
The drop fluid rates are:
15 drop /minute

60 drop /minute
Factors affecting rate given of fluid:
Size of the needle.High of the bottle.
Viscosity of the fluid.
Notes that nurse should be observed:
The rapid of infusion.
The continues of solution into the vein.
The quantity of infusion that patient need.
Any medication that added to the bottle.
The movement of the arm because it cause tension of the vein and out of the needle from vein.
How to calculate the number of drop in minutes:
By using this formula:1000 ml x 15 drop (or 20 or 60)
Number of hours x 60 minutee.g: give (3) bottle of fluid for (8) hours with (20) drop in minute, to the patient?
1500 x 20 = 30000 = 62.5 drop /minute.
