What is the recommended flow rate for a Bag-Valve-Mask (BVM) oxygen delivery?

The recommended flow rate for oxygen delivery through a Bag-Valve-Mask (BVM) is 12-15 Litres per minute. This flow rate is critical because it ensures an adequate supply of oxygen to the patient while minimizing the risk of carbon dioxide buildup and improving ventilation efficiency.

When using a BVM, the goal is to deliver a high concentration of oxygen to the patient, particularly in situations of respiratory distress or failure. Setting the flow rate within the range of 12-15 Litres per minute provides sufficient reservoir oxygen to fill the bag before compressing it to ventilate the patient effectively. This flow rate also helps maintain a positive pressure that can assist in overcoming potential airway resistance and deliver adequate tidal volumes.

Providing oxygen at lower flow rates may not sufficiently fill the reservoir bag, leading to inadequate ventilation, while higher flow rates may lead to excessive pressure, potentially causing barotrauma or discomfort for the patient. Therefore, using this established flow rate ensures both the safety and effectiveness of using a BVM in emergency situations. The flow rate you selected aligns with established guidelines in current practice standards for paramedics.
