What is ambu bag and it's nursing responsibilities?

An ambu bag, or bag-valve-mask (BVM), is a medical apparatus used to provide positive pressure ventilation to individuals who are not breathing adequately or at all. Nursing responsibilities include ensuring the ambu bag is functioning properly, positioning the mask to create an airtight seal over the patient's face, and delivering effective breaths while monitoring the patient's chest rise and vital signs. Nurses must also be prepared to switch to advanced airway management if necessary and document the intervention accurately.
