A New Record

A normal blood CO2 concentration is 40....Andrew, due to his hernia and underdeveloped lungs, is far from normal, and generally a value between 55 and 75 is "within parameters." Before today, the best he had ever gotten was 44. However, because they're weaning the ventilator so slowly since yesterday's procedure, he's at rates much higher than he has been in the last month, giving him the ability to relax and get really comfortable. Today at 4pm, he hit a CO2 concentration of 38.5, a new record.
