Millar Mikro-Tip Pressure catheters have an operating range of -760 to 4000 mmHg; however, their linear operating range is -50 to 300 mmHg.
For any pressures outside the linear range the user must perform a nonlinear calibration over the range of pressures expected. The LabChart Multipoint Calibration Extension can be used to perform this nonlinear calibration.
