== Background and Identification ==

The GE TruSat is a pulse oximeter made by GE Healthcare. Pulse oximeters are non-invasive devices used to monitor a patient’s oxygen saturation. GE Healthcare is a division of General Electric, an American conglomerate. GE Healthcare produces and sells diagnostic imaging agents and medical diagnostic equipment. The company also develops technology for medical imaging, medical diagnostics, disease research, patient monitoring systems, and biopharmaceutical manufacturing. GE sells healthcare products under the Datex, Ohmeda, PerfTrak, OxyTip, TeleOximetry, TruTrack, and PIr brand names.

The GE TruSat device is designed for spot-checking and continuous monitoring of pulse rate and oxygen saturation. It can also monitor during patient motion or low perfusion. It can be with adult, pediatric, and neonatal patients in non-hospital and hospital environments.

The GE TruSat is a pulse oximeter that measures saturated oxygen levels and relative perfusion indices (Plr). The device is powered by an internal battery that can be charged by an external power supply. A backlit display shows the saturated oxygen level, pulse rate, and relative perfusion index. The display also shows alarm limit settings and indicators for battery capacity, silenced alarms, and plethysmographic pulse. Users can change monitor settings such as alarm limits, volume, and backlight level using on-screen controls. Depending on the priority of the alarm, audible and visual signals will be generated by the TruSat. The device’s lock function prevents users from making unintended setting changes.

== Technical Specifications ==

***General***

* Pulse oximetry sensors:  OxyTip+ sensors only
* Method:  red and infrared light absorption
** Red LED wavelength range:  650 to 670 nm
** Infrared (IR) LED wavelength range:  930 to 950 nm
** Average power:  ≤ 1 mW

***SpO2***

* Calibrated for functional oxygen saturation
* Calibration range:  70 to 100%
* Measurement and display range:  1 to 100%
* Display resolution:  1%
* First reading, full accuracy:  ≤ 10 seconds

Accuracy, Arms (root mean square of paired values; previously represented by ± 1 standard deviation)

* 70 to 100% ± 2 digits (without motion)
* 70 to 100% ± 3 digits (during clinical motion)
* 70 to 100% ± 2 digits (during clinical low perfusion)
* Below 70% unspecified

SpO2 measurement accuracy is based on deep hypoxia studies using OxyTip+ sensors on volunteer subjects. Arterial blood samples were analyzed simultaneously on multiple CO-oximeters.

NOTE:  Accuracy may vary for some sensors; always check the instructions for the sensor.

***Pulse rate***

* Measurement and display range:  30 to 250 beats per minute (bpm)
* Display resolution:  1 bpm
* First reading, full accuracy:  ≤ 15 seconds
* Accuracy
** 30 to 250 bpm:  ± 2 digits or ± 2%,  whichever is greater, (without motion)
** 30 to 250 bpm:  ± 5 digits (during motion)
** 30 to 250 bpm:  ± 3 digits (during low perfusion)

***PIr pulsatile value***

* Measurement and display range:  0.01 to 9.99
* Display resolution:  0.01 PIr

***Display***

* Liquid crystal display (LCD)
* Backlight LED:  ON or OFF
* Plethysmographic pulse bar (pleth bar):  ten-segment column; pulsates to indicate pulse rate and signal strength
* Display update time
** SpO2, pulse rate, and PIr values:  1 second ± 0.25 second
** Plethysmographic pulse bar:  20 Hz minimum (.05 second)

***Internal battery power***

* Type:  Internal, rechargeable, nickel-metal hydride (NiMH), 3 AH, 12 VDC, 150 mA
* Self-discharge when stored at room temperature (typical for all NiMH batteries): at least 30% of a full charge remains after 3 months of storage
* Capacity, fully charged, operating at room temperature:
** Without Trend Download option:  35 hours
** With Trend Download option:  24 hours
** NOTE:  Continuous use of the backlight reduces the time approximately 50%.
* Charging time (full capacity):  3.5 hours typical
* Battery indicator:  4-segment symbol; shaded segments represent battery charge (0 shaded = low or depleted; 4 shaded = fully charged)
* Automatic power OFF to conserve battery:  20 minutes after monitoring stops
