No additional disease was noted in the history of a 37-year-old male patient who was brought to the emergency department with cardiopulmonary arrest after drowning at sea. Spontaneous circulation returned following 12 minutes of cardiopulmonary resuscitation. Bedside point-of-care ultrasound (POCUS) revealed multiple and confluent B lines, an irregularity on the pleural line, disappearance in the A-lines, and subpleural hypoechoic areas predominantly in the 2nd, 3rd, 4th and 6th zones of the right lung and the 3rd, 4th and 6th zones of the left lung. The ventilator mode and settings were adjusted according to the POCUS findings, being a safe option in emergency departments for the diagnosis of noncardiogenic pulmonary edema due to drowning and for the management of such patients.eninfo:eu-repo/semantics/openAccessDrowningPOCUSPoint-of-care ultrasonographyPulmonary edema.Article10.5505/respircase.2024.1567913148521300498
