In which condition should patients avoid the use of 100% oxygen after receiving bleomycin?

Patients who have received bleomycin should avoid the use of 100% oxygen primarily due to the risk of pulmonary toxicity, which is particularly significant in those with pulmonary fibrosis. Bleomycin is known to cause lung damage, and administering high concentrations of oxygen can exacerbate this condition.

In individuals with pulmonary fibrosis, the use of 100% oxygen can lead to decreased lung function, worsening the existing damage to lung tissue. Oxygen toxicity can occur in these patients, leading to inflammation and further fibrosis, which can result in serious respiratory complications. Therefore, it's critical to avoid 100% oxygen in this population to prevent potential deterioration of their pulmonary status and to minimize the risk of complications associated with bleomycin-induced lung injury.
