Abstract :
The errors that are incurred by misreading the angle on the oscilloscope face in the determination of pulmonary compliance, resistance, and functional residual capacity with a vector scope are presented. Results indicate that the calculated value will be within 10% of the correct value, provided that the oscilloscope angle is between 10.5 and 78.5 degrees, and the reading error is less than 1 degree.
