Page 7: Summary Of Warnings For The Oxylite Monitor
OxyLite User Manual Summary of Warnings for the OxyLite Monitor Do not attempt to open the OxyLite. There are no user- serviceable parts inside. There is a risk of electrical shock or other injury or permanent damage to the monitor. - Page 8 For safe storage of OxyLite sensors always refit the protective black cover when a sensor is not in use. CAUTION DO NOT drop, stretch or ‘kink’ any part of an OxyLite sensor. Permanent damage may result. CAUTION Attempting to disconnect the sensor by pulling the cable sleeving instead of the front of the sensor connector may cause irreparable damage to the sensor.

OxyLite User Manual to the sensor connector; these data are automatically read by and transferred to the OxyLite monitor upon connection. Available OxyLite functionality is controlled via a functions button at the rear of the monitor. Continuous pO and temperature data from the OxyLite can be acquired for recording, playback and analysis using a suitable data acquisition system connected via a choice of interfaces at the rear of the monitor. - Page 11 Single-sensor multi-parameter monitoring Our OxyLite oxygen and temperature monitor is designed specifically to be used in tandem with our OxyFlo blood flow monitor, providing support for simultaneous measurements of tissue oxygenation, blood flow and temperature using dedicated combined sensors.

Page 21: The Set Button
OxyLite User Manual The SET button OxyLite functionality is controlled via a SET button at the rear of the monitor (see figure 2). Pressing the button when no sensor is connected allows the oxygen units to be selected from a choice of mmHg or kPa. - Page 22 The use of sensors beyond the 6-month calibration period is entirely at the discretion and at the own risk of the user. NOTE: When a sensor with an expired calibration is connected, the OxyLite display will maintain the ‘Use Left | Cal.Expiry’ message until the user presses the SET button at the rear of the monitor.

Temperature Compensation The luminescence-based oxygen monitoring technology employed by the OxyLite is sensitive to temperature. The error in the pO reading due to a discrepancy between the temperature at the site of measurement and the temperature at which the sensor was calibrated (37°C) is dependent upon:... - Page 24 Manual temperature correction Temperature compensation can also be achieved by manual temperature control using the SET button at the rear of the OxyLite monitor. This allows the use of less costly oxygen-only sensors in certain circumstances. Manual temperature control may suffice in situations where the temperature of the monitoring site or fluid is stable and known to within ±2 - 3ºC.

4. C ARE OF Use of OxyLite OxyLite should only be operated on a secure, flat, horizontal surface and in ambient temperatures of 15°C to 30°C. Cleaning and Storage of OxyLite The monitor enclosure may be surface-cleaned by wiping lightly using a soft cloth dampened with a commercial, nonabrasive cleaner. -
Page 28: Cleaning, Disinfection And Sterilization Of Sensors
DO NOT store OxyLite sensors in bright sunlight. CAUTION OxyLite sensors have a limited used or unused total shelf life and a recommended use-by date (printed on the sensor packaging). Both should be considered when establishing sensor inventories. Refer to section 3.7 for further information. -
Page 29: Disposal Of Sensors

CAUTION Disposal of Sensors After use, failure and/or expiry, please dispose of sensors carefully and in accordance with local and national biohazard regulations and guidelines. -
Page 30: Troubleshooting And Maintenance
ROUBLESHOOTING AND AINTENANCE Troubleshooting If you experience a problem using the OxyLite that you are unable to correct by reconnecting the sensor(s) and/or turning off and turning back on the monitor, please contact Oxford Optronix technical support (see p2 of this document). -

OxyLite. Check that the correct data channels are being viewed on the software package provided by the data acquisition module supplier. If the problem persists please contact technical support. - Page 32 Generally speaking, unexpectedly low oxygen readings have a physiological root cause (where used in vivo). For example, the force exerted by the tip of an OxyLite sensor can easily exceed capillary closing pressure. Low pO readings will result if this is the case.

Page 33: Simple Sensor Functionality / Calibration Check
If the subject is being artificially respired using pure oxygen, the tissue pO can exceed normal levels. Under these circumstances, it is possible that tissue pO will exceed the range supported by the OxyLite (i.e. 200mmHg). With very high pO the OxyLite may no longer report an oxygen value and report error state. -
Page 34: Obtaining Technical Assistance
The monitor should be inspected regularly for signs of wear and tear. The OxyLite monitor is supplied with a 2 year warranty. Please refer to the Terms and Conditions of the Warranty at the end of this user manual for further details. -
