10 Monitoring NBP Preparing to Measure NBP

144

CAUTION If you spill liquid onto the equipment or accessories, particularly if there is a chance that it can get

inside the tubing or the MMS, contact your service personnel.

Measurement Limitations

Measurements are impossible with heart rate extremes of less than 40 bpm or greater than 300 bpm, or

if the patient is on a heart-lung machine.

The measurement may be inaccurate or impossible:

• if a regular arterial pressure pulse is hard to detect

• with cardiac arrhythmias

• with excessive and continuous patient movement such as shivering or convulsions

• with rapid blood pressure changes

• with severe shock or hypothermia that reduces blood flow to the peripheries

• with obesity, where a thick layer of fat surrounding a limb dampens the oscillations coming from the

artery

• on an edematous extremity.

Measurement Methods

There are three methods of measuring NBP:

• Manual - measurement on demand.

• Auto - continually repeated measurements (between one and 120 minute adjustable interval).

• STAT - rapid series of measurements over a five minute period, then the monitor returns to the

previous mode. Use only on supervised patients.

Reference Method

The NBP measurement reference method can be Auscultatory (manual cuff) or Invasive (intra-

arterial). For further information, see the Application Note on NBP supplied on the monitor

documentation CD-ROM.

In Adult and Pediatric mode to check the current setting, select Main Setup -> Measurements

-> NBP, and check whether the Reference setting is set to Auscultatory or Invasive. This

setting can only be changed in Configuration Mode.

In Neonatal mode, to comply with safety standards, invasive is always used as the reference method.

This setting cannot be changed and is not visible in any operating mode.

Preparing to Measure NBP

1 Connect the cuff to the air tubing.

2 Plug the air tubing into the red NBP connector. Avoid compression or restriction of pressure tubes.

Air must pass unrestricted through the tubing.
