Final answer:
The two types of oxygen masks are the CPAP mask for sleep apnea treatment and the mask for hyperbaric oxygen therapy, used in pressurized environments to treat conditions like carbon monoxide poisoning.
Step-by-step explanation:
The two types of oxygen masks discussed are the Continuous Positive Airway Pressure (CPAP) mask and the mask used for hyperbaric oxygen therapy.
The CPAP mask is commonly used for the treatment of sleep apnea and is typically affixed to the head with straps, covering both the nose and mouth.
On the other hand, hyperbaric oxygen therapy requires patients to breathe 100% oxygen in a pressurized environment, which is beneficial, for example, in treating carbon monoxide poisoning because it helps displace the carbon monoxide from hemoglobin, allowing the red blood cells to carry oxygen again.
CPAP devices are depicted as being attached to a patient's face with a mask covering the nose and mouth, securing with straps around the head.
In contrast, the masks used in hyperbaric oxygen therapy are seen in pressurized chambers where the divers or patients breathe pure oxygen to treat conditions like the bends or carbon monoxide poisoning.
Unlike carbon dioxide, which would not be beneficial and could actually be harmful, pure oxygen is crucial for treating carbon monoxide poisoning due to its ability to replace carbon monoxide on the hemoglobin molecule.
