Final answer:
The major complications of oxygen toxicity are respiratory alkalosis and pulmonary edema.
Step-by-step explanation:
The two major complications of oxygen toxicity are respiratory alkalosis and pulmonary edema.
Respiratory alkalosis occurs when the blood is too alkaline due to a deficiency in carbonic acid and CO₂ levels in the blood. This condition often occurs when there is excessive CO₂ exhaled from the lungs, such as during hyperventilation.
Pulmonary edema, on the other hand, is the accumulation of fluid in the lungs, leading to difficulty in breathing. Oxygen toxicity can cause damage to the lung tissues, resulting in the leak of fluid into the air sacs and the development of pulmonary edema.
