The need for an oxygen machine is determined solely by the patient's blood oxygen saturation. If the blood oxygen is low, then the ventilator and oxygen machine are used together; if the blood oxygen is normal when using the ventilator, then there is no need to use the oxygen machine additionally. For patients with sleep apnea, don't use an oxygen machine.
Breathing machines and oxygen machines are both a type of medical equipment, but breathing machines and oxygen machines are used on different principles and by different people.
Oxygen machines are generally used for people with increased oxygen consumption, or brain workers who use their brains excessively, including intellectuals, bosses and managers, and students taking exams; urbanites with a stressful pace of life; and long-distance drivers. The ventilator is used in respiratory failure due to various causes, anesthetic respiratory management during major surgery, respiratory support therapy and emergency resuscitation.
The ventilator is a vital medical device that can play a role in preventing and treating respiratory failure, reducing complications, and saving and prolonging patients' lives. Oxygen machines, on the other hand, are devices that produce oxygen-enriched air by filtering nitrogen molecules in the air through a membrane.
