an·er·oid

(an'er-oyd),
Without fluid; denoting a form of barometer without mercury, in which the varying air pressure is indicated by a pointer governed by the movement of the elastic wall of an evacuated chamber. Also used to denote a mercury-free pressure gauge used with some sphygmomanometers.
[G. a- priv. + nēros, wet, + eidos, form]

aneroid

[an′əroid]
not containing a liquid. The term is used especially to describe a device that does not contain liquid, but that performs the same function as a similar device containing liquid. An example is aneroid barometer.

aneroid

adjective Without liquid; fluidless.

an·er·oid

(an'ĕr-oyd)
Not containing liquid (e.g., a sphygmomanometer that does not contain a column of liquid mercury).
[G. a- priv. + nēros, wet, + eidos, form]

When reading mercury column or aneroid manometers, operators tend to error by recording a zero as the last digit in the systolic and diastolic reading rather than the nearest 2 mmHg; for example, 116 becomes 120 or 74 is recorded as 70.
The Aneroid monitor was significantly more variable among those aged over 50 than for those 21 or younger, and the wrist monitor was significantly more variable for those over age 50 than for those 21-24.
The aneroid and wrist measures did not significantly differ from mercury measures at any age.
For those less than 21, the aneroid monitor was significantly lower than the mercury measurement (P = .
The variability of the differences between these measurements and the mercury was highest for participants over age 50, with the exception of the aneroid.
With regard to diastolic pressure, the wrist measure would be graded lower than C, but the arm and aneroid measures would receive B grades.
This study and others demonstrate the inaccuracy of automated BP monitors and traditional aneroid manometers when compared to the gold standard mercury column manometer, especially for different age groups.
