STAN S41

The leading maternal and fetal monitor

The Neoventa STAN S41 is an advanced full featured CTG for monitoring both the mother and fetus during simplex and duplex antenatal screening, labor, and delivery.  Adaptable and configurable with support for wireless and water-resistant monitoring, real-time waveform display and the ability to integrate seamlessly with the leading electronic medical record systems.  The STAN S41 is fully compatible with the Goldtrace ® Fetal Spiral Electrode (FSE).

ARTG ID 424292

ST Analysis

Image of ECG

The ST segment of the electrocardiogram is the isoelectric (flat) section between the S and T waves.  During the period represented by the ST segment, the myocardial cells in heart are recovering from previous contraction (repolarization).   During hypoxia, the energy balance within the myocardial cells is disrupted and the morphology of the ST segment changes causing an apparent elevation or depression of the isoelectric form.  Consequently, changes in the ST segment are marker for myocardial ischaemia or infarction.

ST analysis is an important diagnostic tool for monitoring adult, adolescent and fetal electrocardiograms.

The STAN S41 is the only CTG offering fetal ST monitoring as a fully integrated diagnostic tool.  The intended purpose of the ST analysis functionality is to reduce the incidence of fetal acidaemia and hypoxia by identifying these earlier and with greater sensitivity than would normally be possible with CTG alone.

Options

Wireless Aqua (433MHz) Transducer & Rack

Wireless Aqua (433MHz) Transducer & Rack Operates in the 433MHz frequency range which is suitable for underwater monitoring. The wireless transducers offer mobility during labor, with continuous CTG monitoring. It can also be used during indoor transport situations in healthcare facilities.
