TruSat is backed by a full, three-year warranty. Up to 35 hours of uninterrupted battery life and a fast, full-battery recharge in only three hours.
Small, lightweight design. Only 2.75 lb. (1.25 kg)—less than half the weight of most bedside oximeters. Control at your fingertips with our simple, three-button operation and intuitive menus. Trend memory option stores up to 180 hours of data for extended monitoring. GE TruSat comes standard with proven GE Health Care features:.
Highly visible, backlit screen for easy viewing in all light conditions. Large, easy-to-read numerics. Audible and Visual Alarm. Alarm limits are always visible and saved between uses. Pulse bar waveform GE TRUSAT COMES WITH OXIMETRY SOFTWARE: Trend Download (TD) software on CD-ROM, you can transfer SpO2 data to a PC and generate comprehensive reports traditionally used in sleep studies.
TD software reports include easy-to-read summaries, which let you do the following:. Detail the total times saturation fell below a minimum. Pinpoint the highest and lowest pulse rates and the times they occurred. Zoom in and print specific desaturation events.
GE TRUSAT IS PORTABLE: Intended for everyday use, the GE TruSat is a true hybrid, enabling one oximeter to follow a patient throughout the entire hospital stay. This allows clinicians to continuously monitor their patients’ oxygen saturation wherever they may need to go in the hospital, from emergency room to critical care to general ward. A high-performing oximeter for any patient, anytime, anywhere. With TruSignal—the newest in clinical-motion, low-perfusion technology—and a long battery life, TruSat is the right choice for a broad range of patients.
3 Year Manufacturer's Warranty!!. This tabletop monitor’s lightweight, portable features make it ideal for use in and out of the hospital, including intrahospital transport. GE TRUSIGNAL: A new technology drawing upon our proven history of providing reliable readings in real-world clinical situations. TruSignal offers improved performance, especially during challenging conditions of low-perfusion and clinical motion. With ultra-low-noise technology, TruSignal selects the appropriate clinically developed algorithm to correct weak signals and generate reliable saturation readings.

Ge Ohmeda Trusat Service Manual
Luckily this company is coded so my FSA accepted the purchase (something rare with online companies). I haven't even owned for 12 hours and it's WONDERFUL!! So easy to set up and parent friendly. Wonderful carry bag.
The resusable wrap probe is perfect - truly reusable since it's velcro and non-adhesive - SUPER!!! Comes with everything you need to download data to your computer or even to a printer so you can print data to take to dr. Display is easily read with my daughter's camera monitor which will be plus at night when I need check it from my room!!!
Fast shipping!!! I couldn't be happier! Thank you Turner Medical Co.

TruSat Technical Reference Manual Guidance and manufacturer’s declaration - electromagnetic immunity The TruSat pulse oximeter is intended for use in the electromagnetic environment specified below. The customer or the user of the monitor should assure that it is used in such an environment. To assess the electromagnetic environment due to fixed RF trans mitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the TruSat is used exceeds the applicable RF compliance level above, the TruSat should be observed to verify normal operation.
If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the TruSat. TruSat Technical Reference Manual 1–12. THEORY OF OPERATIONS This chapter contains:. Functional block diagram. SpO, pulse rate, and PI r measurement principles.

Trend Download board block diagram The Trend Download board provides an interface for connecting a personal computer or printer to the monitor. TruSat Technical Reference Manual Alarm event relay The alarm event circuit contains a normally-open relay switch that closes in the event of an alarm condition and remains closed until the alarm condition ends. When S1 is switched to “enable,” a multiple-component circuit responds to an incoming signal, energizes the relay coil, and closes the contact between pin 1 and pin 3 of the RS-232 DIN 6 connector (X2).

SERVICE PROCEDURES This chapter contains procedures for the following:. Checking the operation of the monitor. General maintenance. Installing upgrades, including software and the Trend Download option. Alarm annunciation setup for monitors with the Trend Download option.
TruSat Technical Reference Manual Choose a sensor designed for use on a finger, place it on your finger, and connect it to the monitor. NOTE: All pleth bar segments pulsate until the measured values are displayed. When the SpO and pulse rate values are displayed, verify that the lowest pleth bar segment remains visible while one or more of the other segments pulsate. Record the results for comparison with future leakage current tests. Ground resistance test A case ground resistance test is not necessary or appropriate because the TruSat is a SELV (Safety Extra Low Voltage) device as defined in EN 60601-1, Clause 2.4.2. The monitor is powered by an external DC SELV (12 V) power supply. TruSat Technical Reference Manual 4.2 Planned Maintenance Preventive maintenance and/or calibration are not required for the TruSat pulse oximeter.
Battery To extend the life of the battery:. Fully charge the battery once a month. NOTE: After all four battery segments are shaded, wait at least 20 minutes before you disconnect the monitor from the external power source. Service Procedures 4.3 Software upgrade The software upgrade kit includes an upgrade card that contains current versions of the oximetry, system, and other monitor software. You upgrade the software by inserting this card into a connector located on the System board.
Checking the current software versions Power ON the monitor. TruSat Technical Reference Manual Note the orientation of the ComWheel encoder cable and the speaker cable. Each is “keyed” for correct connection to the System board. Carefully disconnect both cables from the System board and remove the bumper assembly. Locate the software upgrade connector on the System board.
It is circled in Figure 4-2. Service Procedures Installing the Trend Download board WARNING: Power OFF and disconnect the monitor from external power before performing any procedure that involves disassembly of the monitor.
