A 750 ml bag is being infused over 90 min. What is the rate of infusion in ml per hour?

750ml/1.5hr= rateperhour

A750IV12hours

To find the rate of infusion in ml per hour, we need to convert the given time from minutes to hours.

Given:
Bag volume (V) = 750 ml
Infusion time (t) = 90 min

Step 1: Convert the infusion time from minutes to hours.
Since there are 60 minutes in an hour, we can divide the infusion time by 60 to convert it to hours.
90 min ÷ 60 = 1.5 hours

Step 2: Calculate the rate of infusion.
Rate of infusion (R) = Volume (V) ÷ Time (t)
R = 750 ml ÷ 1.5 hours

Step 3: Solve for R.
R = 500 ml/hour

Therefore, the rate of infusion is 500 ml per hour.

To find the rate of infusion in ml per hour, you first need to determine the number of ml infused per minute. Then, you can convert that to ml per hour.

Since the bag is being infused over 90 minutes, and it contains 750 ml, you can calculate the rate of infusion by dividing the total volume infused (750 ml) by the total time taken (90 min):

Rate of infusion = Total volume infused / Total time taken

Rate of infusion = 750 ml / 90 min

Now, let's convert the rate from minutes to hours. There are 60 minutes in an hour, so we can divide the rate by 60 to convert it into hours:

Rate of infusion = (750 ml / 90 min) * (1 hour / 60 min)

Simplifying, we get:

Rate of infusion = 750 ml / (90 min * 60 min)

Calculating the value, we find:

Rate of infusion = 750 ml / 5400 min

Finally, we can express the rate of infusion in ml per hour by multiplying the rate by 60:

Rate of infusion = (750 ml / 5400 min) * (60 min / 1 hour)

Simplifying, we get:

Rate of infusion = 750 ml / 5400 min * 60 min

Calculating the value, we find:

Rate of infusion ≈ 8.33 ml/hour

Therefore, the rate of infusion is approximately 8.33 ml per hour.
