Summary: | Spirometer is needed in the medical world but not all hospitals have
facilities spirometer. The high price of a spirometer is one of the factors why the
unavailability of a spirometer at each hospital or clinic. To solve the problem then
be made a low-cost spirometer with a simpler device. Spirometer which was made
in this project is the flow spirometer that uses a method of measuring differential
pressure, design of mouthpiece uses a model of orifice, and it can measure Forced
Expiratory Volume in First Second (FEV1) and Forced Vital Capacity (FVC).
Data acquisition system consists of pressure sensors MPX2010DP, differential
amplifier, a microcontroller ATmega8535, and a computer to display the
measurement results.
Spirometer was tested to a man 27 years with height 167 cm and a woman
28 years with height 163 cm. According to the predictive value of Pneumobile
Project Indonesia, for men to have FEV1 predictive value is 2,838 L and FVC
predictive value is 3,835 L. While the value of FEV1 of the measurement results is
2,434 L and FVC values is 3,452 L. For women to have FEV1 predictive value is
2,625 L and FVC predictive value is 2,988 L. While the value of FEV1 of the
measurement results is 2,230 L and FVC values is 2,603 L. Interpretation of
spirometer results for both samples have a normal condition. |
