What is the best technique for delivering BVM ventilations when no advanced airway is in place?

The two-person technique is the best method for delivering bag-valve-mask (BVM) ventilations when there is no advanced airway in place because it effectively ensures proper ventilation and minimizes the risk of complications. This technique involves one provider squeezing the bag to provide the breaths, while the other provider maintains a proper seal on the mask to prevent air leaks and ensure that air is delivered effectively to the patient's lungs.

In this technique, one rescuer focuses solely on administering ventilations, while the second rescuer ensures that the mask fits snugly against the patient's face and helps to open the airway, often by performing a head-tilt-chin-lift maneuver or a jaw-thrust maneuver. This coordinated effort improves the quality of the ventilations, allowing for more effective oxygen delivery, particularly in patients who may require assistance due to inadequate breathing or respiratory distress.

This method is particularly beneficial in comparison to a one-person technique, in which it can be challenging for a single provider to achieve optimal ventilation without assistance, increasing the likelihood of inadequate air delivery or difficulties in ensuring a proper mask seal. The terms “child technique” and “adult technique” do not specifically describe the best method for delivering BVM ventilations and may not encompass the advantages gained through teamwork
