Air-Shields, Inc. was founded in 1939 in Hatboro, Pennsylvania, where it continued to be based until 2004, when it was acquired by Dräger Medical. Best known for its incubators, Air-Shields also made ventilators, patient monitors and other medical equipment. In 1960, the company advertised three new continuous monitors for cardiac patients. One of these tracked both pulse and temperature, another tracked both pulse and blood pressure. The third could track blood pressure and, at the turn of a switch, either pulse or temperature.
The Air-Shields Pulse-Blood Pressure-Temperature Monitor, shown here, was also called the Model PTB-2. It was equipped with a blood pressure cuff, a pulse meter that would be attached to the patient's finger, and a temperature-reading probe that could be positioned in the patient's mouth … or elsewhere.
