John was a clerk in a small store, and he had no health insurance coverage. His salary was $9 per hour. He barely could make ends meet.

Dr. Tsosie examines Sacheen and asks about her symptoms and health history. She checks the level of oxygen in Sacheen’s blood by attaching a device called a pulse oximeter to Sacheen’s finger (Figure ). Dr. Tsosie concludes that Sacheen has bronchitis, an infection that commonly occurs after a person has a cold or flu. Bronchitis is sometimes referred to as a “chest cold,” so Sacheen’s wife was right! Bronchitis causes inflammation and a build-up of mucus in the bronchial tubes in the…
