Why is the use of a BVM not recommended during single-provider CPR?

The use of a Bag-Valve-Mask (BVM) is not recommended during single-provider CPR primarily because it slows down the rate of chest compressions. Effective chest compressions are crucial during cardiac arrest, as they maintain circulation and oxygenation of vital organs. The prioritized goal of CPR is to provide high-quality, continuous compressions at the correct rate (100-120 compressions per minute), with minimal interruptions.

When a single provider attempts to use a BVM while managing CPR, there is often a significant time taken to achieve a proper seal and deliver breaths effectively. This diversion of focus and time can lead to reduced compression rates, which is detrimental to the patient’s chances of survival. Interruptions in chest compressions can increase the risks of inadequate blood flow to the heart and brain, ultimately affecting outcomes.

Using a BVM is more effective in a team setting, where one provider can maintain compressions while another manages ventilation. In single-provider situations, emphasizing the quantity and quality of compressions takes precedence to ensure the highest chance of survival until further assistance arrives.
