One of the mysteries of the English language finally explained.
Relating to or denoting a barometer that measures air pressure by the action of the air in deforming the elastic lid of an evacuated box or chamber.
- ‘The mercury sphygmomanometer is a reliable device, but all too often its continuing efficiency has been taken for granted, whereas the aneroid manometer, which is not generally as accurate, is often assumed to be as reliable.’
- ‘These digital devices deflate at about 4 mm Hg per second, making them sometimes seem slower to use than auscultatory aneroid devices, but they are more accurate.’
- ‘These devices include mercury column monitors, which are being phased out of use, and aneroid monitors.’
- ‘We calibrated the blood pressure measurement system prior to use each day with an aneroid sphygmomanometer.’
- ‘Thirdly, although aneroid sphygmomanometers are more popular than mercury instruments, they require regular calibration and checks for common defects such as non-zeroed gauges, cracked face plates, or defective rubber tubing.’
- ‘The aneroid sphygmomanometers were inspected and calibrated by the Biomedical Engineering Department of the University of Michigan Health Systems.’
- ‘He used a standard-sized, calibrated aneroid sphygmomanometer blood pressure cuff to measure pressure in the left arm.’
- ‘Elevation was determined using an aneroid altimeter.’
- ‘On July 17, 1929, he flew the first instrumented payload, consisting of an aneroid barometer, a thermometer, and a camera.’
- ‘The digital monitor is easier to use than the aneroid monitor.’
- ‘He said that because Welch Allyn makes aneroid and digital blood-pressure devices in addition to those containing mercury, he had no further comment.’
An aneroid barometer.
- ‘He pointed out that some Midwestern facilities began phasing out mercury-containing sphygmomanometers and switching over to aneroids a few years ago, at the urging of St. Mary's Duluth clinic.’
Mid 19th century: coined in French from Greek a- ‘without’ + nēros ‘water’.
