What measurement is typically used to express the infusion rate?

The infusion rate is most commonly expressed in milliliters per hour (mL/hr). This measurement provides a clear understanding of how much fluid is being delivered to the patient over the duration of one hour, which is crucial for maintaining accurate dosing and monitoring the patient's fluid intake. By using mL/hr, healthcare providers can quickly calculate the total volume to be infused over longer periods, making it easier to manage infusions in various clinical settings.

Using this standard measurement allows for consistency and ease of communication among medical professionals. Other units, like drops per minute (gtt/min) or drops per hour (gtt/hr), may be used in specific scenarios or for specific types of infusions that involve gravity drip systems, but mL/hr is the most universally recognized metric in modern infusion therapy.
