Which intervention is the first step for patients requiring ventilation?

Bag-mask ventilation (BVM) is the first step for patients requiring ventilation because it offers a quick, non-invasive way to provide positive pressure ventilation. In emergency situations, establishing an airway and ensuring adequate ventilation are crucial initial steps in patient care, especially when a patient is unable to breathe adequately on their own.

BVM can be performed rapidly and effectively in various environments, making it an essential skill for EMS providers. It allows for continuous monitoring of the patient's response to ventilation and can be used as a temporary measure while considering more advanced airway management options, should they be needed. This method is suitable for a wide range of patients who are not breathing adequately or at all, making it a go-to intervention in the field.

Advanced airway management techniques, such as the use of endotracheal tubes or laryngeal tube airways, while essential in certain situations, typically follow the initial use of BVM when ventilation support is immediately required. Cricothyrotomy is a surgical airway intervention indicated in severe cases where other methods have failed or are not possible and should only be performed when absolutely necessary.
