Question

What complications can result from O2 toxicity?

a) Hyperthermia and increased blood pressure.
b) Respiratory alkalosis and hypotension.
c) Pulmonary edema and atelectasis.
d) Elevated blood glucose levels and bradycardia.

Answer 1

Complications from O2 toxicity include pulmonary edema, which is fluid accumulation in the lungs, and atelectasis, the collapse of lung tissue, as well as respiratory alkalosis due to increased pH levels in the blood.

Step-by-step explanation:

The complications that can result from O2 toxicity include pulmonary edema and atelectasis. When exposed to high concentrations of oxygen for extended periods, the lungs can become damaged due to oxidative stress, leading to fluid accumulation in the lung tissue or pulmonary edema. Furthermore, atelectasis, which is the collapse of part or all of a lung, can occur as a result of high oxygen levels disrupting the surfactant that helps keep the airways open. Symptoms such as respiratory alkalosis may also be observed due to the elimination of carbon dioxide faster than it is produced, resulting in a higher pH level in the blood.
