Static Lung Compliance (Cstat) Calculation

pressure

peep

Calculates pressure needed to overcome elastic resistance to ventilation.

Static Lung Compliance

Graham Walker, MD, is an emergency physician practicing in San Francisco, California. Dr. Walker attended medical school at the Stanford University School of Medicine and then trained in emergency medicine at St. Luke’s-Roosevelt Hospital Center in New York City, where he was Chief Resident. He returned to the west coast as a Medical Simulation fellow and attending in Stanford’s emergency department. More relevant, of course, is that Dr. Walker is the creator and developer of MDCalc and remains active in content and calculator development, along with our many other endeavors as President of MD Aware, LLC (MDCalc’s parent company).
