Application Areas

The SenTec Digital Monitoring System is a safe, accurate and reliable way for continuous, noninvasive monitoring of carbon dioxide tension and oxygen tension as well as oxygen saturation and pulse rate in adult and pediatric patients and enables clinicians to better assess patient ventilation and oxygenation in virtually all clinical settings.

Please refer to following Application Areas for detailed information:

Always in Touch...The SDMS allows continuous monitoring of transcutaneous carbon dioxide tension (tcPCO2) and oxygen tensions (tcPO2) in neonates. Versatile sensor application (thorax, abdomen, back, low on forehead, inner or anterior aspect of tight) facilitates continuous measurement in virtually all clinical situations. 

Safe Sensor Temperature Management

The digital V-Sign™ and OxiVent™ Sensors always stay in touch with your patient while safely measuring, supervising and controlling its temperature at the application site. The SenTec Digital Monitoring System allows a safe “plug and play” measurement with safety temperature management features: institution-restrictable sensor temperature, site inspection requests and – if missed – automatic sensor temperature reduction.

Gentle Sensor Application

You will always keep the sensor in touch with your patient, because the SenTec Digital Monitoring System provides you with a very gentle sensor application solution. The sophisticated sensor temperature management concept described above is one of these gentle sensor application features. For the most gentle sensor application to your patient, the SenTec's transcutaneous Sensor is extremely lightweight (less than 2,9 g), includes a highly-flexible cable, and keeps its full freedom of rotation if applied to the patient. Moreover, the neonatal attachment ring is devoted to the particular needs of neonatal skin: its design allows you a forceless sensor application and a smooth remove without damaging the sensitive skin when peeling off after monitoring. 

Reliable Measurement Performance 

Transcutaneous carbon dioxide tension values painlessly provide you with a precious estimate of arterial carbon dioxide tension levels. With the lowest technical drift of the currently available transcutaneous monitors, the digital V-Sign™ Sensor provides accurate transcutaneous carbon dioxide tension values even during long-term measurement [Storre 2010].  The OxiVenT™ Sensor measures PO2 optically with dynamic fluorescence quenching. This measurement principle is stable over time and therefore virtually drift free.

Convenient Operation 

“Always in touch with your patient” implies the possibility of up to 12 hours calibration free monitoring. Compared to spot check monitoring techniques, the continuous clinical information delivered by SenTec's transcutaneous sensor enables you to detect patient condition changes earlier and thus gives you more time to induce an optimized therapy according to your patient’s needs. Without the need of an additional calibration request, you can even disconnect the digital Sensor from the “Sensor Adapter Cable” within a disconnection time of up to 30 minutes. This allows you to examine, treat, or transport your neonatal patient with the convenience of extra mobility. This facilitates the operation of the measurement system especially around a neonatal incubator.

Clinical Application Examples

Safe Long-term Application in NICUToday’s gold standard to determine the arterial carbon dioxide tension in critically ill neonates is arterial blood gas analysis. This requires periodical arterial blood sampling with its drawbacks of invasiveness, risk of complications, procedure pitfalls, and iatrogenic anemia in neonatal patients. The SenTec Digital Monitoring System provides continuous, transcutaneous carbon dioxide and oxygen tension monitoring system, being safely applied to your neonatal patient. Application of the sensor is gentle, the sensor temperature management is extremely secure, and the operation is maximized for the neonatal patient and your convenience. The SenTec Digital Monitoring System’s long-term accuracy and applicability has been proven by Walsh et al. at the Children’s Hospital Vanderbilt, Nashville, TN, USA.  They tested the SenTec Digital Monitoring System on their smallest patients weighing between 1000 and 3400 grams. The measurement periods amounted up to 50 hours of tcPCO2 monitoring per sensor application site. The study affirmed the device’s safety (no adverse skin effects), and clinical relevant correlation of its tcPCO2 readings with arterial carbon dioxide tension [Walsh].
Neonatal Management Ventilation GuidanceDuring high frequency oscillation ventilation (HFOV) or non-invasive ventilation (NIV) procedure one cannot solely rely on common arterial carbon dioxide surrogate measurement techniques.  Rowley et al. tested if transcutaneous PCO2 measured with the SenTec Digital Monitoring System (SDMS) could reliably replace arterial blood gas analysis required during high frequency oscillation ventilation (HFOV) of neonatal patients. They determined a significant correlation between tcPCO2 measured with the SenTec Digital Monitoring System and arterial carbon dioxide in their neonatal patients with very low birth weight as well as in neonatal patients receiving vasopressors [Rowley]. The continuous tcPCO2 monitoring allows adjusting HFOV and may help to minimize sequela (i.e. intraventricular hemorrhage) resulting from wide arterial carbon dioxide tension swings [Rowley].  

Publications for SenTec Digital Monitoring System

The SenTec Digital Monitoring System (SDMS) with the V-Sign™ Sensor is a safe, accurate and reliable way to track and monitor changes in arterial carbon dioxide, arterial oxygen saturation and pulse rate. Measuring tcPCO2 and SpO2 noninvasively, the V-Sign™ Sensor enables clinicians to better assess patient ventilation and oxygenation in virtually all clinical settings. There is a fast growing number of published clinical studies which were conducted to test and prove the usability, reliability and accuracy of the SDMS.
