Also known as: ALS, Lou Gehrig's disease
The central case of the episode follows Dr. Nate Lennox, a biochemistry professor with advanced ALS who is found wandering and disoriented at an ice rink. His progressive neurological degeneration has left him paralyzed and dependent on a wheelchair with eye-tracking communication technology. The episode explores his deteriorating condition and end-of-life decision-making.
Also known as: Lung infection
Nate presents with bilateral lung infiltrates and low oxygen saturation (89%), requiring BiPAP support. The pneumonia becomes the acute medical crisis that forces decisions about intubation, tracheostomy, and mechanical ventilation in the context of his advanced ALS.
Also known as: Breathing failure
Due to progressive muscle weakness from ALS and acute pneumonia, Nate's forced vital capacity drops to 32% of normal, necessitating assisted ventilation via BiPAP and ultimately a tracheostomy with mechanical ventilation.
Also known as: Emotional incontinence
As part of his ALS progression, Nate experiences pseudobulbar affect with exaggerated emotional responses and uncontrolled crying, which his caregiver Fran explains as 'emotional incontinence' caused by nerve deterioration.
Also known as: Difficulty swallowing
Flashbacks show Nate's progressive difficulty swallowing due to weakening bulbar muscles, leading to a choking episode in 2002 and placement of a gastrostomy tube (G-tube) for nutritional support.
Also known as: Bleeding
During the tracheostomy procedure, Nate experiences significant bleeding when the surgical instrument punctures his innominate vein due to unusual anatomy. This requires conversion to an open procedure, vascular repair, and blood transfusion.
