The recommendation to use the E-C position when operating a bag-valve-mask (BVM) is based on effective airway management strategies when multiple providers are available. The E-C position allows one provider to create a proper seal on the mask while simultaneously opening the airway with the other hand. This technique is particularly effective because it enhances the ability to deliver positive pressure ventilation more efficiently.

By adopting the E-C position, the provider can ensure that the mask fits snugly against the patient's face, which reduces the risk of air leaks, promoting better oxygenation. The use of the E-C hold is essential for both adult and pediatric patients when multiple rescuers are present, as it optimizes the coordination and effectiveness of the ventilation effort.

While the E-C position is beneficial, it is not restricted to any specific demographic group nor limited to team emergencies; it is simply a preferred technique for effective ventilation when there are enough trained personnel available to assist. Therefore, stating that the E-C position is recommended when multiple providers are available is indeed accurate.
