5. Problems with IV Drip Controlling and MonitoringIV drip rates change during a 30-45 minute IV administration.Nurses sometimes re-count and re-adjust IV drip rates 2-3 times per administration.Time-consuming and overwhelming with a high volume of patients.

17. Time needed to Fasten Velcro Tie to Roller ClampAverage time for six individuals to properly fasten Velcro tie to roller clamp. Error bars indicate standard deviation. N = 5 trials per individual.
18. Average IV drip rate at t = 15 minutes and t = 30 minutes for control and two treatment conditions. Error bars indicate standard deviation. N = 5 trials per condition.
19. Average IV drip rate at over time for control and two treatment conditions. Symbols represent a statistically-significant difference (p < 0.05) in drip rate compared to other specific time points. Symbols and their respective time points (in minutes) are listed: * - 0; # - 5; † - 10; ‡ - 15; ^ - 25; $ - 30. For example, the drip rate at t = 0 minutes is significantly different from that at 15, 25, and 30 minutes. Error bars indicate standard deviation. N = 5 trials per condition.
20. COVID necessitated resourceful design, yielding a simple, but effective, solution.
21. Future StepsImprovements to experimental designConsideration of other factors that cause drip rates to changeExpansion of scope
22. A Takeaway:Effective design is often simple design.
