Technical

“Dr. Elmer Isaac McKesson (1881-1935) was internationally known as an expert in the use of nitrous oxide for general anesthesia. He published extensively on this subject, and even offered graduate courses in the technique. He is best known as an inventor and manufacturer of anesthesia equipment, and the founder of the McKesson Appliance Co. Introduced in 1930, the Recording Nargraf was the first anesthesia machine capable of creating automated anesthesia records. It is but one example of McKesson's creative skills and foresight. The Model J Nargraf pictured here could record onto moving chart paper data useful to the anesthesiologist, such as the patient’s blood pressure, the percentage of oxygen being administered to the patient, and the patient’s respirations. The patient’s heart rate was marked onto the chart paper by hand.” (ref.2)
