The main objective when treating hypoxia (a deficiency of oxygen in the tissues) and hypercapnia (a high concentration of carbon dioxide in the blood) is to give sufficient oxygen to ensure that the patient is safe and his or her condition does not deteriorate. However, while giving too little oxygen can result in hypoxia, which can result in death, excessive oxygen therapy can also be dangerous for some patients.
治疗低氧血症（组织中氧气不足）和高碳酸血症（血液中二氧化碳浓度过高）时的主要目标是提供足够的氧气，以确保患者安全且病情不会恶化。然而，虽然给予的氧气过少会导致低氧血症，进而可能导致死亡，但过度的氧疗对某些患者也可能是危险的。
