Successful treatment of 1 patient with chlorine-induced ARDS using awake self-prone positioning and nasal high-flow oxygen: A case report.

RATIONALE: Accidents involving chlorinated compounds in the context of cleaning are not uncommon. However, improving the treatment success rate for acute respiratory distress syndrome (ARDS) patients caused by chlorine gas presents significant challenges.

PATIENT CONCERNS: A 28-year-old female was admitted to the intensive care unit after accidental inhalation of chlorine gas resulting in ARDS.

DIAGNOSES: The patient was diagnosed with ARDS attributed to chlorine gas exposure.

INTERVENTIONS: The intervention involved utilizing a combination of awake self-prone positioning (ASPP) and high-flow nasal oxygen therapy for treatment.

OUTCOMES: After continuous ASPP and high-flow nasal oxygen therapy, the patient quickly recovered and was transferred out of the intensive care unit on the 6th day without any adverse events.

LESSONS: ASPP combined with high-flow nasal oxygen therapy can improve patients' hypoxemia, prevent the need for intubation, avoid rapid deterioration of the condition, reduce treatment complexity, and lower mortality rate.
