Social Security Disability – 3 Flow Calibration
SSD and OSHA require a calibration at three different flow rates. Midmark Diagnostics
Group has incorporated a feature that requires calibration at 0.5 L/s, 1.5 L/s and 3.0 L/s.
On the Calibration Tab of Spirometry Settings, there is a check box for Multi-Flow
Calibration. If this box is selected, you must calibrate at three different flow rates. The
program will display the Multi-Flow Calibration window and will measure the flow rates
as the user injects the 3 liters. If the flow is too fast, the program will reject the injection
and ask the user to try again with a slower injection. If the flow is too slow, the program
will reject the injection and ask the user to try again with a faster injection.
When injecting the 3 liters, try to keep the graph on the left hand side in line with the
dotted red line, or, on the right hand side, try to keep the bar moving at the same speed as
the blue arrow.

OSHA Regulations
OSHA Regulations are outlined in the Recommended Standardized Procedures for
Pulmonary Function Testing published in the Federal Register. At a minimum, OSHA
requires:
 Calibrate with both Spirometer and syringe at the same temperature.
 Proper calibration of the Spirometer daily. (three different flow rates)
 Calibrate for volume and time or flow and time (we provide volume and time).
 Calibrate before each shift.
 Calibrate whenever the Spirometer is transported.
 Calibrate after every thirty tests or sooner (2-3 hours) under field test conditions.
