It is intended to be used in the management of critically ill patients of any age, but especially neonates, by providing continuous blood gas data while permitting the simultaneous monitoring of blood pressure via an external transducer. The Neotrend sensor is designed for use in conjunction only with the custom umbilical artery catheter supplied when the umbilical artery is to be the access site. The sensor is used in conjunction with the Paratrend 7 Multiparameter Senior and/or Satellite Monitor systems. ## Device Story Neotrend Multiparameter Sensor provides continuous blood gas monitoring (pO2, pCO2, pH) and temperature; intended for critically ill patients. Input: intravascular blood samples via umbilical or femoral artery access. Principle: optical fibre/fluorescence quenching for pO2; photometric absorption for pCO2 and pH; thermocouple for temperature. Output: continuous data displayed on Paratrend 7 Senior or Satellite Monitor systems. Used in clinical settings by healthcare providers; allows simultaneous blood pressure monitoring via external transducer. Benefits: real-time blood gas data for management of critically ill patients. Device is a modification of Paratrend 7 sensor, replacing Clark electrode with optical technology. ## Clinical Evidence Bench testing only. Accuracy and precision evaluated using tonometers maintained at 37°C with precision gas mixtures. Measured values compared against calculated actual partial pressures. Bias and precision calculated over relevant gas ranges. Results demonstrated comparable performance between Senior and Satellite monitor systems. ## Technological Characteristics Materials: fibre optic sensors. Sensing: fluorescence quenching (pO2), photometric absorption (pCO2, pH), thermocouple (temp). Connectivity: integrates with Paratrend 7 Senior/Satellite monitors. Form factor: intravascular catheter. Software: analogue/digital processing. ## Regulatory Identification An indwelling blood carbon dioxide partial pressure PCO2 analyzer is a device that consists of a catheter-tip PCO2 transducer (e.g., PCO2 electrode) and that is used to measure, in vivo, the partial pressure of carbon dioxide in blood to aid in determining the patient's circulatory, ventilatory, and metabolic status. ## Special Controls *Classification.* Class II (special controls). The special control for this device is FDA's “Class II Special Controls Guidance Document: Indwelling Blood Gas Analyzers; Final Guidance for Industry and FDA.” ## Predicate Devices - Paratrend 7 Intravascular Blood Gas Monitoring System - Paratrend 7 Satellite Multiparameter Blood Gas Monitoring System - Optex Blood Gas Monitoring System - Neocath 1000 Umbilical Artery Oxygen Monitoring System ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

The Paratrend 7 Multiparameter Senior and Satellite Monitor Systems with Neotrend Multiparameter Sensor is a modification of the Paratrend 7 Intravascular Blood Gas Monitoring System and Paratrend 7 Satellite Multiparameter Blood Gas Monitoring System. Furthermore, it is also judged to be substantially equivalent to the Optex Blood Gas Monitoring System and the Neocath 1000 Umbilical Artery Oxygen Monitoring System. #### Device Description The Neotrend Sensor (N7004S) is a modified version of the currently legally marketed device, the Paratrend 7 sensor (MPS7004). The measurement of pO2 using an electrochemical sensor (Clark electrode) in the predicate Paratrend 7 sensor has been replaced in the Neotrend device by a sensor based on optical fibre/fluorescence quenching technology. All other measurement parameters are essentially unchanged. The application has been expanded to include umbilical artery access. #### Intended Use The Neotrend Multiparameter Sensor is inserted via an intravascular access device into the vascular system, e.g. umbilical artery (neonates), femoral artery (paediatrics, adults). It is intended to be used in the management of critically ill patients of any age, but especially neonates, by providing continuous blood gas data while permitting the simultaneous monitoring of blood pressure via an external transducer. The Neotrend sensor is designed for use in conjunction only with the custom umbilical artery catheter supplied when the umbilical artery is to be the access site. The sensor is used in conjunction with the Paratrend 7 Multiparameter Senior and/or Satellite Monitor systems. {2}------------------------------------------------ # Technological Characteristics ## Measurement Technology i | pO₂ : | fibre optic, fluorescence quenching | |--------|-------------------------------------| | Temp : | thermocouple | | pCO₂ : | fibre optic, photometric absorption | | pH : | fibre optic photometric absorption | ## Monitor Technology Analogue/digital . . . . {3}------------------------------------------------ #### Comparison of Accuracy to the Predicate Paratrend 7 Device The device under review was manufactured under standard process conditions and calibrated on the Senior Monitor. The tonometers were maintained at 37℃ and were pre-equilibrated with precision gas mixtures thereby allowing the calculation of "actual" partial pressures. The Henderson-Hasselbalch equation is used to determine the "actual" pH values in the different tonometers. The measured (displayed) values were recorded after a 15 minute equilibration time. The PDMs were then transferred to Satellite monitors and the measured readings recorded. The PDMs were then returned to the Senior monitor prior to transferring the sensor to the next equilibrated tonometer. The data were analysed by calculating the bias (the mean of the differences between the measured Paratrend 7 value and that the actual value of the equilibrated solution) and the precision (sample standard deviation of the differences). The data were collected over the relevant range of gases. The differences obtained on both Senior and Satellite systems are comparable. #### Conclusion The data presented above satisfies product accuracy claims and shows comparable results for both Senior and Satellite. The device under review is considered substantially equivalent. {4}------------------------------------------------ Image /page/4/Picture/2 description: The image shows the seal of the Department of Health & Human Services (HHS) of the United States of America.
