Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a sub-low temperature oxygen therapy device. Background Art

[0002] Cardiac arrest is the sudden cessation of heartbeat and breathing in patients. Brain tissue is most sensitive to ischemia and hypoxia, and serious damage can occur 4-6 minutes after cardiac arrest. Therefore, despite active rescue and restoration of heartbeat, patients often die or suffer from serious neurological defects due to severe brain damage. For this type of sudden disease, the most common treatment is oxygen therapy.
