How is the BVM attached for oxygen delivery during step 5?

The BVM, or bag-valve-mask, is designed to deliver positive pressure ventilation, and during the oxygen delivery step, it is crucial to ensure that the mask creates a proper seal around the patient's face. An easy seal mask is specifically designed for optimal fit and effectiveness, which is essential when using a BVM to provide sufficient oxygen. This type of mask reduces the risk of leaks, ensuring that the maximum amount of oxygen reaches the patient's lungs.

Using a mask that does not provide an adequate seal, like a standard mask or a nasal cannula, would compromise the effectiveness of ventilation. A standard mask may not fit all patients securely enough to ensure consistent delivery of oxygen, while a nasal cannula is not suitable for the high flow of oxygen needed in conjunction with a BVM. Similarly, attaching the BVM directly to the oxygen tank without a mask would not provide effective ventilation, as it eliminates the crucial connection to the patient's airway. Thus, using an easy seal mask allows for safe and efficient oxygen delivery during emergency situations.
