What is the common flow rate for a bag-valve-mask resuscitator (with oxygen reservoir)?

The common flow rate for a bag-valve-mask (BVM) resuscitator with an oxygen reservoir is often set at 15 liters per minute (LPM). This flow rate is sufficient to provide high concentrations of oxygen to the patient while preventing the bag from collapsing and ensuring an adequate supply of oxygen for ventilation efforts. A flow rate of 15 LPM allows for optimal delivery of oxygen during positive pressure ventilation, as it compensates for the air that is drawn in with each squeeze of the bag, thereby facilitating effective ventilation. Higher flow rates may increase oxygen delivery further but are generally not necessary, and can lead to wastage of oxygen. It's important to set the flow rate accurately to ensure that the resuscitation efforts are both effective and efficient.
