Intravenous infusion is a method of introducing a large amount of sterile liquid, electrolyte, and drug into the body by intravenous pressure using the principle of atmospheric pressure and hydrostatic pressure.
Intravenous infusion flow calculation
\(drops per minute=\frac {flow coefficient x volume volume}{infusion time (minutes)}\)
\(infusion time (hours) = \frac {flow coefficient × volume volume} {drops per minute × 60 minutes} \)
In the formula:
Flow coefficient: drip / ml, generally 15 drops / ml
Capacity of the volume： 200mL
Time： 60min
Discharge coefficient： 15gtt/mL
Velocity of flow： 50gtt/min
