AN OXYGEN CHAMBER SIMPLIFIED IN DESIGN AND OPERATION

JAMA. 1931;97(6):390-391. doi:10.1001/jama.1931.27310060001009a
Abstract

In 1926 I1 described a ventilated oxygen tent in which adequate cooling and drying of the air was achieved by passing the air directly over chunks of ice instead of through metal coils. It was found that this provided a more comfortable atmosphere for the patient than had been formerly secured.2 Since that time, I have modified the tent by providing an increased ventilation as well as a rheostat which regulates the degree of air movement and thus the amount of cooling of the air necessary, a factor that varies in individuals of different weights. Thus, infants require a higher atmospheric temperature, and the air flow through an ice and salt mixture should be much reduced. Children and small adults give off less heat than adults and need a moderate air movement, whereas large adults should have a large air movement to lower the atmospheric temperature within the
