Non-Stress Test Report
9
It is generally accepted that a non stress test (
NST report process uses fetal ultrasound (but not DECG) heart rate traces and the Maternal Toco
Trace, generating a printed report when criteria are met and the test can be considered reassuring. The
American term Non Stress Test (NST) is used for antepartum testing. The interpretation algorithm
and ruleset are equivalent to those implemented in OB TraceVue Revision F.xx, and are based on the
2008 NICHD guidelines.
An NST report is a diagnostic aid, but it does not replace the clinician's judgment. The interpretation
and the appropriate clinical response remain with the clinician.
A fetus normally produces characteristic heart rate patterns. Average baseline variability and
acceleration of the FHR in response to fetal movement are considered reassuring signs. This test does
not take into account any form of external fetal stimulation.
For every active ultrasound fetal heart rate measurement, one NST report can reside in the monitor's
memory. The reports are cleared when you discharge a patient and when you start a new NST report.
When the NST Report option is available and the "NST Report" feature is "on", the NST status for all
available ultrasound fetal heart rate measurements is displayed as a permanent element within the
application area on the resting display.
The minimum displayed information is:
•
NST identification (by FHR number: 1, 2, 3)
•
Current NST status (by color: inverse for "not started yet", white for "running", yellow for
"stopped", green for "finished")
