Why is the pH reading fluctuating when I use the pH and reference electrodes connected to the FE165 pH Amp?
This issue is most likely caused by inadequate filling of the reference electrode barrel with KCl reference solution, or an issue with the composition of the reference solution (e.g., it has been diluted or has degraded). To correct for both...
Why is the end systolic volume (ESV) larger than the end diastolic volume (EDV) in the PV-Loop Module's Hemodynamics table?
The catheter's volume sensing segments are not fully in the left ventricle. This temporally mis-aligns the pressure and volume data, and causes the LabChart PV-Loop Module to incorrectly identify the EDV and ESV values. For further technical...
