Final answer:
The location of oxygen delivery devices depends on the protocols of the medical facility or design of the ambulance. Oxygen is vital for various medical emergencies, inclusive of CPR, and is measured in treatments like the Douglas bag method. AEDs, used alongside CPR for cardiac events, are also found in ambulances and public areas.
Step-by-step explanation:
The question of where oxygen delivery devices are located is specific to the context of the scenario presented, which seems to be oriented towards the medical field, likely an emergency or hospital setting. It is important for health professionals and emergency responders to know the location of these devices to ensure prompt and effective patient care. Oxygen is crucial for various medical procedures and emergencies, such as providing ventilation to patients with respiratory issues or during CPR (cardiopulmonary resuscitation). The Douglas bag method can be utilized to measure a patient's oxygen consumption and CO2 production during varying grades of activity or muscular exercise. Furthermore, Automated external defibrillators (AEDs) are commonly found in both ambulances and public places and are used in conjunction with CPR in cases of cardiac arrest. The specific answer to where oxygen delivery devices are located is not given here, as it likely depends on the protocols of the medical facility or the design of the emergency vehicle.
