Also known as: Heat stroke
May, a senior citizen evacuated during a power outage, suffers critical heat stroke with multi-organ damage. Despite aggressive cooling measures, her condition proves fatal, and the team compassionately creates a virtual Paris experience for her final moments.
Also known as: V-tach
Edna, a 90-year-old woman, experiences worsening ventricular tachycardia due to heat exposure, leading to cardiac arrest requiring CPR and defibrillation. The resuscitation fractures her ribs and leads to imaging that reveals a large tumor.
Also known as: Lung cancer
A massive tumor discovered incidentally during Edna's chest CT extends from her right lung to her abdomen. Despite her age and risks, Edna insists on aggressive surgical resection, which requires removal of her kidney and will necessitate dialysis.
Also known as: Abnormal heart vessel
Brooks, a 52-year-old cyclist, collapses during exercise. Investigation reveals his coronary artery originates from the pulmonary artery instead of the aorta—a rare structural anomaly causing cardiac ischemia and arrest. Complex surgery during a power outage using Civil War-era techniques (heated cauterization) successfully corrects the defect.
Also known as: Severe dehydration
Brooks initially presents with severe dehydration from cycling in extreme heat, making IV access difficult and contributing to his cardiac event.
Also known as: Alzheimer's disease
Multiple elderly patients evacuated from the senior residence exhibit dementia with wandering behavior, requiring wander bracelets and close monitoring during the heat emergency.
Also known as: Spinal cord damage
Dr. Lim's ongoing spinal cord injury affects her autonomic function, making her more susceptible to heat-related complications. She also grapples with accepting her disability and begins participating in wheelchair basketball.
Also known as: Broken rib
Edna sustains rib fractures during CPR compressions, which leads to the chest CT that discovers her tumor.
