Final answer:
An emergency oxygen delivery system consists of three parts: an oxygen source, an oxygen delivery device, and oxygen tubing. The oxygen flows from the source, through the tubing, and is delivered to the patient using the delivery device.
Step-by-step explanation:
The three parts of an emergency oxygen delivery system are:
- Oxygen source: This can be a cylinder, tank, or concentrator that supplies the oxygen.
- Oxygen delivery device: This can include a nasal cannula, face mask, or non-rebreather mask.
- Oxygen tubing: This connects the oxygen source to the delivery device and allows the flow of oxygen.
During an emergency, the oxygen source is activated, and the oxygen flows through the tubing to the delivery device. The delivery device is then placed on the patient's face or inserted into their nose, providing them with the necessary oxygen to breathe.
