OxiVenTTM

Overcoming limitations
of arterial blood gases,
etCO2 and SpO2 monitoring

Assessing ventilation and oxygenation in neonatal patients is a challenge. With the SenTec OxiVenT™ Sensor, a new generation of transcutaneous measurement technique overcomes the limitations of current methods and helps healthcare professionals to guide ventilation and oxygenation-related treatments in neonates

For better patient outcomes where it matters most.

Why SpO2 is not enough

Due to the S-Shape of the ‘oxyhemoglobin dissociation curve’ (ODC) hyperoxemia/ hyperoxia cannot be dectected by pulse oximetry (SpO2). Monitoring tcPO2 provides a crucial parameter to avoid the risk of hyperoxia and severe complications such as Retinopathy of Prematurity (ROP)

Arterial Blood Gas sampling

Provides only a snapshot every few hours and bears the risk of invasiveness, especially in neonatal patients.

Why SpO2 is not enough

Is sometimesinefficient in patients with small tidal volumes and inapplicable in certain ventilation modes such as HFO.

Two different

10 years

Different display options:

tcPCO2, tcPO2 and
heating power trends

Baseline and Delta values

Set baseline and markers

Set a baseline just before changing the treatment to assess the impact on the patient’s ventilation and oxygenation.

User profiles

Quickly adapt settings to your needs: select individually customized profi les stored on the monitor

Trendlines allow early detection of
ventilation and oxygenation changes

Estimates of PaCO2 and PaO2 in treanline, baseline, and delta values.

Relative Heating Power

(RHP) shows the required heating power to keep the Sensor at set temperature. Changes of RHP may be attributable to changes in perfusion.

Delta values

Numerical indication of the diff erence between the current reading and the reading from the set Baseline and 10 min before.

Effective & efficient monitoring

Save your time for the important tasks

SmartCalMem

Disconnect the Sensor (e.g. to untangle cables or to move the patient) without removing the Sensor from the patient. No need to recalibrate the Sensor when re-connecting.

Automatic calibration management

Simply store the Sensor in the Docking Station – calibration is fully automatic. Within a few minutes “Ready for Use” status is established and maintained until patient application.

Easy maintenance

One simple tool to perform the membrane change. Membrane life up to 42 days.

Transportable

Lightweight, dedicated mounting plates/roll stands, battery life up to 10 hours.

Excellent accuracy

In Vitro performance test of the SenTec OxiVenT™ tcPO2 compared to a clark type electrode demonstrates higher accuracy [internal data].

Comparison between tcPCO2 measured with the SenTec Digital Monitoring System and arterial carbon dioxide in neonatal patients [Rowley] shows high correlation and accuracy*.

Safe sensor temperature &
site time management

  • Redundant sensor temperature controls to avoid the risk of skin irritations.
  • Automatic, institution-restrictable site time control and site inspection intervals.
  • Automatic sensor temperature reduction if site time has elapsed and site inspection is missed.
  • Safety-relevant parameters are password protected.
  • A low Sensor temperature of 41°C (tcPCO2) and 43°C (tcPO2) is recommended in neonatal patients.

Automatic artifact detection

Automatic data quality verifi cation and artifact detection.

Multi Site Attachment Rings (MAR)

The design enables a gentle sensor application and a smooth removal without damaging the sensitive skin.

Best signal quality

Digital Sensor with integrated CPU. Measured signals are digitized and preanalyzed in the Sensor head for the best signal quality.

Connectivity / Data Management

Direct connectivity to Patient Monitoring Systems.

Clinically trusted

Clinical usage of over 1000 SDMS with V-Sign™ in neonatal units and over 2000 SDMS in pediatric/ adult units around the world.
