    A 76-year-old man developed moderate ARDS after inhaling chlorine gas from a trichloroisocyanuric acid disinfectant in a swimming pool.

  • 3

    The patient was treated with noninvasive mechanical ventilation, awake prone positioning, and glucocorticoids, resulting in complete recovery.

    Chest imaging revealed bilateral pulmonary infiltrates consistent with acute toxic inhalation lung injury and ARDS.

  • 5

    Chlorine poisoning lacks a specific antidote, necessitating treatment focused on symptom control and monitoring until stability is achieved.
