Converting 10-20 ml/hour to ml/minute
To convert 10-20 ml/hour to ml/minute, divide by 60: 10-20 ml/hour equals 0.17-0.33 ml/minute. 1
Conversion Formula and Calculation
- The basic formula for converting flow rates from ml/hour to ml/minute is to divide the hourly rate by 60 minutes 1
- For 10 ml/hour: 10 ml/hour ÷ 60 minutes = 0.17 ml/minute 1
- For 20 ml/hour: 20 ml/hour ÷ 60 minutes = 0.33 ml/minute 1
Clinical Applications
- This conversion is commonly used when calculating medication infusion rates, particularly for critical medications requiring precise administration 1
- In clinical settings where fluid administration rates need to be monitored closely, understanding both hourly and per-minute rates is essential 2
- For patients receiving fluid resuscitation, crystalloid may be administered at 10-20 ml/kg over 10-15 minutes, which would require converting to a per-minute rate for manual administration 2
Practical Implementation
- For manual gravity drip calculations, the drops per minute would depend on the drop factor of the IV tubing 1
- For a 10 ml/hour infusion with standard macrodrip tubing (15 drops/ml), the drip rate would be approximately 2.5 drops per minute 1
- For a 20 ml/hour infusion with the same tubing, the drip rate would be approximately 5 drops per minute 1
Important Considerations
- Electronic infusion pumps are preferred over manual gravity drip calculations for medications requiring precise administration 1
- When administering medications with narrow therapeutic windows, always double-check rate calculations to avoid dosing errors 3
- For pediatric patients, calculation errors can be more consequential due to weight-based dosing and smaller volumes 4
- Always verify calculations with another healthcare provider when administering critical medications or when working with unusual flow rates 5
