Also known as: Drowning
Meredith drowns in Elliott Bay after the ferry accident and is brought to the hospital in cardiac arrest with severe hypothermia (body temp 86°F). The entire episode centers on the medical team's prolonged resuscitation efforts using warming techniques, CPR, ACLS protocols, and eventually achieving return of spontaneous circulation after over 90 minutes.
Also known as: Cold exposure
Meredith's core body temperature drops to 86°F from cold water immersion. The team uses the protective effects of hypothermia while working to rewarm her to 98.6°F using gastric lavage with warm fluids and other warming techniques, experiencing afterdrop phenomenon during the process.
Also known as: Memory loss
The pregnant Jane Doe patient wakes up with complete retrograde amnesia following the ferry accident, unable to remember her name, family, or any details about her life before the trauma. The team considers this could be from head trauma or psychological shock.
Jane Doe is pregnant and agitated after waking with amnesia post-ferry accident. Addison and Alex manage her care, monitoring the baby while addressing her oxygen needs and psychological distress. They later reveal the baby is a girl and appears healthy.
Also known as: Early-onset Alzheimer's
