Final answer:
Oxygen therapy for shock treatment is required when a patient lacks adequate oxygen supply to the tissues. It can be administered through a non-rebreather mask or a hyperbaric chamber, which increases oxygen concentration in the blood. Hyperbaric chamber therapy is specifically effective in treating carbon monoxide poisoning.
Step-by-step explanation:
In cases of shock treatment, oxygen therapy is required when a patient is not receiving an adequate supply of oxygen due to shock, pneumonia, or another illness. When the circulatory system is unable to maintain blood flow to adequately supply sufficient oxygen and other nutrients to the tissues, oxygen therapy is used to increase oxygen levels and support cellular metabolism.
Oxygen therapy can be provided in different ways, such as through a non-rebreather mask or a hyperbaric chamber. In a hyperbaric chamber, the atmospheric pressure is increased, causing a greater amount of oxygen to diffuse into the bloodstream. This therapy is particularly beneficial in carbon monoxide poisoning cases, as it helps to displace carbon monoxide from hemoglobin by increasing the concentration of oxygen in the blood.
