Problem:
Erroneous NBP
measurement Solutions
1. Check for proper cuff size:
a. Too small a cuff can give an erroneously high value.
b. Too large a cuff can give an erroneously low value.
2. Check for residual air left in the cuff from a previous measurement.
3. Make sure cuff is not too tight or too loose.
4. Make sure cuff and heart are at same level, otherwise hydrostatic
pressure will offset the NBP value.
5. Minimize patient movement during measurement.
6. Watch for pulsus paradoxus.
7. Check for leak in cuff or tubing.
8. Patient may have a weak pulse.
9. Calibration may be necessary.
