Dr. Whetstone's letter

Letter of Recommendation from William D. Whetstone M.D. on April 1, 2020.
April 1, 2020

Tom and All,

Thank you for the incredible work on this project. Your in-person successful demonstration of the Emergency field ventilator leads me to recommend it as a temporary backup device when I no longer have access to a ventilator. Obviously the patients would have to be sedated and paralyzed which is a typical post-intubation state while in the Emergency Department. Given the current grave situation in our country and in many of our largest cities I will be pursuing further testing and research at our hospitals under the current FDA guidelines. Although it would be a public health victory to avoid using this field ventilator, we have to prepare for the possibility of our hospital and EMS systems being completely overwhelmed with critical patients. Your design and testing have led me to believe that I could use this unit to save lives in that setting.
