What is the drop factor for normal saline?
The drops per minute would be calculated as total volume, divided by time (in minutes), multiplied by the drop factor of 60 gtts/min, which also equals 41.6, rounded to 42 drops per minute. Let’s look at an example of an IV piggyback medication… Ancef 1gm in 100 mL normal saline to be infused over 30 minutes.
How many liters of blood can you lose?
