Mix 18 units of oxytocin in 750 mL NS. Start infusion at 20 mL/hr. Increase by 5 mL/hr every 10 minutes until uterine contractio
ns are 2 to 3 minutes apart. Do not exceed 40 milliunits/min. Maintain total IV fluid volume at 100 mL/hr. You have calculated that 480 milliunits/hr will be delivered. How many milliunits per minute will be delivered?
Look at your R-R ratio, depending on the time segment attributed to each square you can then do the math and find time between waves, then find the number of R waves in minute
