Who can receive a bag-valve-mask resuscitator (with oxygen reservoir)?

A bag-valve-mask resuscitator with an oxygen reservoir can be used on both breathing and non-breathing patients because it serves multiple purposes in providing respiratory support. For non-breathing patients, the device is primarily used to deliver positive pressure ventilation, helping to provide oxygenation and ventilation until further medical assistance can be provided. For breathing patients who may be experiencing issues such as inadequate ventilation or respiratory distress, the bag-valve-mask can also enhance oxygen delivery, particularly when used with an oxygen reservoir. This versatility makes the device an essential tool in emergency response situations, allowing for effective support across a range of patient needs.
