Stopping A Measurement; Use Of Comments - ADInstruments Human NIBP Nano Owner's Manual

31

Stopping a measurement

To stop recording simply click Stop in LabChart.
Once you have completed a measurement, it is recommended to:
1. Disconnect the finger cuff air hoses from the Wrist Unit – this
removes any residual air pressure from the finger cuff s and protects
the finger cuff s from accidental inflation and damage.
2. Unwrap and remove the finger cuff s and take the Wrist Unit away
from the subject.
If the Human NIBP Nano is returning error messages or failing to start a
measurement, it is best to disconnect the finger cuff air hoses from the
Wrist Unit, turn the Human NIBP Nano Interface off and back on, reapply
the finger cuff (s) and restart the LabChart soft ware before resuming a
measurement.
When you remove a finger cuff aft er stopping a measurement, it is
recommended to inspect the finger to see if you can find the place
where the two components of the plethysmograph have pressed on the
finger skin. Usually, some coloring of these pressure points can be seen
immediately aft er removing the cuff s. Verify that the pressure points were
correctly centered between the knuckles and symmetrically placed.

Use of Comments

With the ADInstruments Human NIBP soft ware installed, LabChart enters
comments automatically when finger cuff switching occurs, for example
'Switching to finger cuff 2', and when the HCU is not zeroed or connected.
When finger cuff switching occurs, no sensible data is recorded for a
period of almost 30 seconds, and blood pressure measurements in the
1–3 minutes following finger cuff switching are less reliable. Hence, these
comments can be useful when analyzing large data files. For example,
by using Commands > Multiple Add to Data Pad... and selecting Find
Using: Comment, you can automate your analysis to the Data Pad, which
is an Excel-like spreadsheet embedded within LabChart. See the LabChart
Help for further details.
