What is the primary goal of using a bag-valve-mask device?

The primary goal of using a bag-valve-mask device is to create positive pressure in the airway. This device is utilized to provide ventilatory support to patients who are unable to breathe adequately on their own. By squeezing the bag attached to the device, the EMT creates positive pressure, which forces air into the patient's lungs when the mask is sealed correctly over their face.

This is crucial in emergency situations where the patient may be experiencing respiratory failure or insufficient breathing due to various medical conditions. The effective use of a bag-valve-mask system can enhance oxygenation and ventilation for the patient, which is vital for preventing further deterioration and supporting recovery. It is important in scenarios where maintaining airway patency and delivering adequate ventilation becomes essential.

While providing high-concentration oxygen can be a secondary benefit when supplemental oxygen is incorporated, the primary function of the bag-valve-mask device focuses on positive pressure ventilation.
