The IscAlert™ sensor system measures the partial pressure of carbon dioxide in peripheral tissue, such as forearm muscle tissue, where the sensor is inserted. The system is intended for monitoring trends in this parameter as an adjunct in the evaluation of the perfusion status of tissue in patients at risk of developing ischemia. IscAlert values are relative within an individual and should not be used as the sole basis for decisions as to diagnosis or therapy. The IscAlert™ sensor system should not be used in peripheral brain tissue, intra cranial tissue, all organ tissues including cardiac and kidney, and other peripheral muscle tissues other than forearm muscle.

The IscAlert sensor system measures partial pressure of CO2 (pCO2) in peripheral tissue, such as forearm muscle tissue, where the sensor is inserted. The system is intended to monitor pCO2 trends as an adjunct in the evaluation of perfusion status of tissue in patients at risk of developing ischemia. Ischemia is a medical term for a shortage of blood supply to tissue. If severe, it can lead to death of the affected tissue (infarction). The tissue pCO2 increases significantly during the early and reversible stages of ischemia. This methodology provides the ability to identify the onset of ischemia events through real-time data. The IscAlert sensor system consists of three parts: - 1. The sterile disposable Sensors - 2. The Connection Unit (CU) - 3. Software to be installed in an off-the-shelf PC unit The sterile, disposable, catheter tip sensors are placed 2-5 cm into organ tissue with a split-off needle that is removed after insertion. The sensor is connected via a cable to the Connection Unit (CU). The CU processes the signals from the sensor unit. It is connected via a cable to a PC with the IscAlert software application installed. The software enables visualisation of the monitoring results.

The TrendCare Calibrator is an accessory for use with the TrendCare Monitors. Sensors and Patient Data Modules calibrated with the TrendCare Calibrator may be used with the TrendCare Satellite Monitor (TCM6000) or TrendCare Senior Monitor (TCM7000).

The TrendCare Calibrator is a microprocessor-based device powered from the mains (line) supply. The device incorporates: - A LCD display for user prompts. - A series of LEDs for system status indication. - Keys for selecting and initiating calibration. - Calibration chamber. - Connections to calibration gas cylinders. - Location fixtures for the multiparameter sensors. The calibration chamber is located on the front of the Calibrator unit, and is opened by pressing the latch to release the door. The sensor is calibrated by connecting it to the PDM patient cable, placing the tonometer in the calibration chamber, closing the door and securing the introducer, and pressing the START CAL key. A three point calibration of the sensor is performed by bubbling three precision mixtures of oxygen, carbon dioxide and nitrogen in sequence through the tonometer solution surrounding the sensor. These gases change the partial pressure of oxygen and carbon dioxide and the pH in the tonometer to defined values. The calibration gases are contained in cylinders located at the base of the Calibrator. The cylinders are identical to the predicate device. Each cylinder contains a different precision mixture of gases. These gases are automatically passed in sequence through the tonometer when the calibration sequence is initiated. Each of the cylinders contains sufficient gas for multiple calibrations. The cylinders are disposable, and should be discarded when empty (see the Instructions on the cylinder labels).

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. Within the United states market, the use of this device should be limited to 72 hours.

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.

The modified SensiCath Sensor, when used as part of the Point-of-Care Blood gas Monitor System is intended to provide on-demand arterial blood gas monitoring in the operating room and at the bedside for critically ill patients requiring an arterial pressure monitoring line. The ABG information is available to the attending qualified medical professional on demand and within approximately 60 seconds of the time the sample cycle was initiated. The intended use of the modified SensiCath Sensor is the same as the predicate SensiCath Sensor.

It is the intention of Optical Sensors Incorporated (OSI) and Marquette Electronics Incorporated (MEI) to introduce into commercial distribution a modification to the SensiCath Arterial Blood Gas Sensor. The modified sensor has a longer useful life and allows a greater number of ABG measurements. The modified sensor is substantially equivalent to the SensiCath Sensor presented in the SensiCath™ Point-of-Care Blood Gas Monitor System which received Food and Drug Administration (FDA) clearance to market, 510(k) K95 1094. The modified SensiCath Sensor operates with the SensiCath Point-of-Care Blood Gas Monitor System, just as the predicate SensiCath Sensor. As with the predicate sensor, the modified SensiCath Sensor measures blood gas parameters of partial pressure of oxygen (PO2), partial pressure of carbon dioxide (PCO2) and the blood's hydrogen ion concentration, (pH). The modified SensiCath Sensor is manufactured and sterilized by Optical Sensors Incorporated, as is the predicate SensiCath Sensor.

The Olympus System is intended to provide on-demand arterial blood gas monitoring in the operating room and at the bedside for critically ill patients with a pre-existing arterial pressure monitoring line. The ABG information is available to the attending qualified medical professional on demand and within approximately 60 seconds of the time the sample cycle was initiated.

It is the intention of Optical Sensors Incorporated (OSI) to introduce into commercial distribution an Olympus Critical Care Monitoring System (Olympus System). The Olympus System supports modules and sensors used in monitoring critical parameters at the patient bedside. The module and sensor referenced in this submission are the cleared-to-market arterial blood gas module (ABG Module) and SensiCath optical sensor unit (SensiCath Sensor). When the Olympus System includes an ABG Module and SensiCath Sensor, monitoring of arterial blood gas at the point-of-care is accomplished. The Olympus System has three main components: - 1. an optical arterial blood gas sensor, hereafter referred to as the SensiCath Sensor. - 2. a module, the Arterial Blood Gas (ABG) Module, hereafter referred to as the ABG Module and, - 3. an operator interface (display, control knob) with electrical and mechanical support for the ABG Module, hereafter referred to as the Olympus Monitor.
