What is the flow rate for a humeral intraosseous (IO) access?

The correct flow rate for humeral intraosseous (IO) access is 105 ml/min. This flow rate is clinically significant as it influences how quickly medications and fluids can be administered during critical situations.

The humeral IO site is often chosen in emergency situations where intravenous (IV) access is challenging or time-consuming. Its flow rate is important to ensure that life-saving interventions can be delivered rapidly, especially in trauma or cardiac arrest cases. The 105 ml/min rate has been observed to provide adequate perfusion and absorption of fluids and medications directly into the central circulation, facilitating quicker therapeutic effects.

Other values for flow rates are generally lower and may not provide the same level of efficacy in emergency scenarios, where time is of the essence. Hence, understanding the proper flow rate for humeral IO access ensures that medical personnel can make informed decisions and act swiftly in life-threatening situations.
