What is the flow rate of oxygen provided by a bag-valve mask (BVM)?

The flow rate of oxygen provided by a bag-valve mask (BVM) is typically set at around 15 liters per minute (LPM). This rate is crucial for ensuring that the patient receives adequate oxygenation, especially in emergency situations where they may be unable to breathe effectively on their own.

Administering oxygen at this flow rate helps to optimize the delivery of oxygen to the patient's lungs, as BVMs are designed to create a seal around the patient's face and deliver a concentrated amount of oxygen with each breath squeezed into the bag. At 15 LPM, the setup accommodates a sufficient volume of oxygen to fill the bag and allows for effective positive pressure ventilation. This is particularly important in cases of respiratory distress or failure where maintaining oxygenation is critical.

The standard practice emphasizes using this flow rate to support adequate gas exchange while minimizing the risk of complications, such as gastric insufflation, which can occur if the rate or technique is not optimal. Effective use of the BVM with the correct flow rate plays a vital role in prehospital emergency care.
