IV Flow Rate Formula

$$\text{Flow Rate} = \left( \frac{\text{Volume (mL)}}{\text{Time (hr)}} \right) \times \text{Flow Factor}$$

Where:

• Volume = total fluid volume to be administered (mL)
• Time = duration of infusion (hours)
• Flow Factor = multiplier depending on units required (e.g., 1 for mL/hr, 16.67 for drops/min at 60 min/hr)

The IV Flow Rate calculator is used in medical settings to convert infusion requirements into a practical flow rate for administration. It allows customization based on the desired unit output, whether in mL/hr or drops/min, using a flow factor. Accurate calculation helps optimize IV therapy and ensures that patients receive fluids and medications safely and effectively.
