In order to perform preventative maintenance on you NIBP (Non-Invasive Blood Pressure) Monitor you will need the following equipment: Electrical Safety Analyzer, NIBP Analyzer.

Check the following and record your observations.

Qualitative Tests

  • Chassis - verify physical integrity, cleanliness
  • AC Plug - verify integrity
  • Line Cord - verify proper insulation and integrity
  • Strain Reliefs - verify physical integrity at both ends of line cord
  • Tubes/Hoses/Bulb – check condition of all tubing, all hoses,the cuff, and the bulb (if present).
  • Fittings/Connectors - examine all fittings and connectors
  • Controls/Switches - verify proper operation
  • Pump – Check the physical condition and proper operation
  • Battery – verify physical integrity (if accessible) and operation, and alarms
  • Indicators/Displays - verify proper illumination and operation
  • User Calibration – verify operation of the calibration function
  • Alarms – verify visual and audible alarms
  • Audible Signals – confirm operation of any audible signals
  • Labeling - verify presence and placement of all labels, placards, instruction cards, etc.
  • Accessories – inspect cuff for leaks and proper closure
  • Deflation Switch – confirm operation of manual deflation
  • Operation on Volunteer – verify operation of device on yourself. Also perform item 2.4 at this time.

Quantitative Tests

  • Grounding Resistance [< 0.5 ohm]
  • Chassis Leakage [< 300 microamps]
  • Air Leakage – Check for leakage of the cuff [<15mmHg/min]
  • Heart Rate – Verify heart rate on a volunteer or simulator [+/- 10%]
  • Pressure Accuracy – Verify pressure at 80, 120, & 200 mmHg [+/- 3mmHg]

Keep in mind that you should record all of your findings from both the qualitative and quantitative tests! Log all data and keep track of it for future reference. Preventative Maintenance is the best way to ensure your machine has a longer shelf life.  It also helps to ensure that your machine continues to function properly.
