NBP Monitoring: Troubleshooting
Troubleshooting
Problem: Erroneous NBP
measurement
Solution:
1. Check for proper cuff size:
 Too small a cuff can give an erroneously high value.
 Too large a cuff can give an erroneously low value.
2. Check for residual air left in the cuff from a previous measurement.
This could indicate a hardware problem that may require service.
3. Make sure the cuff is not too tight or too loose.
4. Make sure the cuff and the heart are at the same level; otherwise
hydrostatic pressure will offset the NBP value.
5. Watch for pulsus paradoxis.
6. Check for leak in cuff or tubing.
7. Patient may have a weak pulse.
8. Calibration may be necessary.
