Collins Respirometer

WLMD ID: aknp
In 1928, Warren E. Collins, Inc., manufactured the first modern iron lung machine. Collins is better known as the maker of respiratory diagnosis instruments. This 9 Liter Respirometer was made from the 1930s through the 1960s. It recorded numerous lung and heart functions of patients, either at rest or in motion. These included tidal volume (the amount of air exchanged with each breath),maximum breathing capacity (the amount of air exchanged by breathing rapidly and deeply), oxygen deficit (an indication of low blood oxygen, measured today by pulse oximeters), and vital capacity (the amount of air a person can exhale after taking his deepest breath). The apparatus contained the carbon dioxide absorbent, Baralyme, allowing the patient to rebreathe his own air. The results of all these tests were recorded by ink tracings on the revolving paper drum.

Note Type: General
Notes: The early year in the date range for the possible year of manufacture is generously based on the dates of publications in which the 9 liter Collins Respirometer was mentioned. The earliest date found was 1955, but earlier years have not been ruled out. The later year in the date range is based on the year that the company moved its manufacturing facility from Boston to Braintree, Massachusetts. The respirometer described here has a manufacturer marking with the address for Boston. A slide presentation of unknown date by Dott. Andrea Innocenti of U.F. Medicina del Lavoro includes an image of a Collins Respirometer that might be a 9 liter model. Dr. Innocenti dated the image as 1953. The date range could change if documentation indicates it should be corrected.

Note Type: Historical
Notes: This respirometer was used for tests that measure how well a person’s lungs take in and release air and how much oxygen is absorbed from the atmosphere into the body’s circulation. The patient followed specific instructions for inhaling and exhaling through tubing that was connected to the left side of the respirometer. Movements in the water-sealed spirometer on the left were recorded on graph paper attached to rotating drums on the right. The end result was a visual and numerical representation of the patient’s breathing functions.

Respirometers might be used to assess a patient before surgery, to test an anesthesia machine or to measure breathing and metabolism in a research setting. Anesthesiologiststs use smaller respirometers, that function via different mechanisms, on anesthesia machines to measure the volume and rate of the patient’s breathing. Respirometers are one of the instruments that aid in monitoring the patient during anesthesia to ensure optimal care as well as to detect potential problems.

This respirometer was manufactured by Warren E. Collins, Inc. of Massachusetts. The company also manufactured the first “iron lung” (an early ventilator) designed by Dr. Philip Drinker in 1928. A few years later an iron lung designed by John Emerson (1906-1997) became a more favored model.
