The acronym ECMO is short for artificial lung. Artificial lung technology is an advanced life support technology. Although it is effective in saving patients’ lives, its use is very expensive, approximately$100,000 or more per use. Based on the duration of the patient’s use of the artificial lung, the cost of the artificial lung is approximately$10,000 to$30,000 per day. The cost of using artificial lung is on the one hand the consumption of the machine itself and equipment tubing, and on the other hand the cost of drugs, examination, etc. Therefore, patients can decide whether to apply the artificial lung technology according to their financial situation and their doctors’ recommendations.
