Introduction: Health care economics restricts many health
centers from using hi-tech diagnostics equipment. Mercury
manometers are used for calibration of pressure transducers. If
standardized it would be a cost effective, simple alternative to
transducers in low economic settings.
Aim: To analyse the feasibility of mercury manometer usage in
respiratory pressure measurement.
Materials and Methods: The experimental study was
conducted with 30 healthy volunteers of age group 17–19 yrs.
They were recruited by using simple random sampling method.
The volunteers were made familiarized to lab environment,
instrument and techniques of maximum inspiratory (Pimax)
and expiratory pressures (Pemax). Then parameters were
recorded using mercury manometer connected to different
syringes as mouth piece (2.5 ml, 10 ml, and 20 ml) and with
sphygmomanometer. Statistical analysis was done by using
IBM SPSS statistics version 21.
Results: The Pimax was 111.07 ± 6.53 with a 2.5 ml syringe as
mouth piece. With 20 ml syringe it was 61.47 ± 9.98. PEmax
with 2.5 ml syringe was 70.33 ± 8.19 with a confidence limit
of 2.93 and with sphygmomanometer was 99.33 ± 8.16 with
a confidence limit of 2.92. There was a change in recorded
pressure and the correlation analysis result showed a significant
difference from both above and below 10 ml mouth piece
range.
Conclusion: Mercury manometers could be used for
recording respiratory pressures in low economic facilities once
standardized. Size of syringe to be used as mouth piece needs
further more works although this study finds 10 ml syringe as
suitable. |
