To Interface a Water-Sealed Spirometer to a Computer,which of the Following

Question

To interface a water-sealed spirometer to a computer,which of the following is required?
A) An X-Y plotter with analog input
B) A variable-speed kymograph
C) A small pneumotachometer
D) A linear potentiometer

Accepted Answer

A linear potentiometer is a device that can convert the movement of a spirometer into an electrical signal that can be read by a computer. It is commonly used in spirometry equipment to measure lung function parameters such as forced expiratory volume (FEV). A water-sealed spirometer uses water to create a seal between the patient's mouthpiece and the spirometer, which helps to prevent air leaks and ensure accurate measurements. However, this type of equipment requires a linear potentiometer to interface with a computer for data analysis and storage.
