Robert Alvin Berman (1914-1999) was an American anesthesiologist and inventor.
Berman designed and developed products to solve the problems of airway management. His ideas for using plastic to make single-use medical equipment were at the forefront of this field.
In 1949, during residency an incident occurred which heralded the development of a translucent oropharangeal airway. Whilst performing a laryngoscopy he noted a safety pin in the pharynx. He deduced the pin had come from inside one of the black rubber multi-use Guedel airway that he and his fellow residents kept in their pockets along with safety pins (…of course these were washed between patients…)
Berman discussed the option of a translucent airway device with his neighbour (Meyer Moch – a plastic fabricator) to prevent the issue from recurring. In Moch’s basement they fashioned the original Berman airway from some butyrate tubing heated over an open flame. As luck would have it, Moch had no pharyngeal reflexes and Berman was able to use his mouth to model the fit…

- Died on November 21, 1999
Berman Airway (1949 – US2599521A)
In one aspect my invention comprises a respiratory airway having two coextensive passageways open along the full length thereof and separated by a rib. The use of open passageways makes for easy cleaning under direct vision; it is impossible in the respiratory airway of my invention for any mucous or other foreign matter to go undetected.Berman 1949
Berman Resuscitube (1952 – US2758593A)
In the 1950s, as more attention was focused on resuscitation, he developed the Resuscitube and a hand bellows for resuscitation, the Respir-Aider. Berman felt mouth-to-mouth resuscitation was unsanitary but met resistance from anesthesiologist and resuscitation researcher James Otis Elam (1918-1995)
…to provide a novel mouth-to-mouth resuscitator which may be readily manipulated and will eliminate the necessity of physical contact between the mouth of the person being treated and the mouth of the person seeking to accomplish the resuscitation and which at the same time may be readily sanitized, and produced and stored under sanitary conditions.Berman 1956
Berman and Elam later became friends and worked on airway management ideas together. Dr. Berman later helped Dr. Elam sell his idea for an Ambu Bag. Also during this time, he patented a plastic blood pressure
Berman Quik Cuff (1956 – US2981251A)
Berman patented a plastic blood pressure cuff, Quik Cuff® feeling that the blood pressure cuff was easily soiled and not hygienic to use repetitively from patient to patient.
Berman’s innovations with plastic were at the forefront of utilizing plastic in medicine and allowed the era of disposability to begin.
In the 1970s, Berman tried to further tackle innovations in airway management by making a blow-molded endotracheal tube; anatomically shaped endotracheal tubes; and presented a tapered endotracheal tube
In 1979, Berman resurrected an idea he had in residency, an intubating airway. His new Berman Intubating Airway led the way for a generation of intubating devices for blind and fiberoptic intubation.
The Berman Intubating Pharyngeal Airway, provides a tubular airway having an openable side to allow passage of appropriate medical and surgical appliances, such as an endotracheal tube, into the larynx and trachea without the use of a laryngoscope. The side opening airway permits blind oral intubating of the larynx and esophagus with ease even in difficult cases of cardiopulmonary-resuscitation and anesthetic procedures.
The intubating airway is designed to place an endotracheal tube into the larynx and trachea while at the same time providing an adequate pharyngeal airway itself.
The lateral opening at the side of the airway allows the airway to be removed from the mouth, leaving endotracheal tube in place. The airway is designed primarily to place the endotracheal tube into the trachea and at the same time provide an adequate pharyngeal airway by itself. The extra large lumen of the airway separates the tongue from the pharynx allowing a wider unobstructed air passageway from the lips to the larynx.Berman 1978
