Page 12: Warnings, Cautions, And Notes
Chapter 1: Introduction Warnings, Cautions, and Notes WARNING! Federal law (USA) restricts this device to sale by, or on the order of, a physician. WARNING! This device is not intended for continuous patient monitoring. This device is intended to measure the patient’s %SpO and pulse rate values. - Page 13 Chapter 1: Introduction WARNING! IEC 950 approved equipment must be placed outside of the “patient environment.” The patient environ- ment is defined as an area 1.5 m (4.92 feet) from the patient. Figure 1-1: Patient Environment WARNING! When attaching sensors with Microfoam® tape, do not stretch the tape or attach the tape too tightly.
- Page 14 Chapter 1: Introduction NOTE! Operation of this device may be adversely affected in the presence of computed tomograph (CT) equipment. NOTE! Use only SpO sensors supplied with, or specifi- cally intended for use with, this device. NOTE! SpO measurements may be adversely affected in the presence of high ambient light.

Page 19: Theory Of Operation
Chapter 2: General Description Theory of Operation The oximeter determines SpO and pulse rate by passing two wavelengths of light, one red and one infrared, through body tissue to a photodetector. During measurement, the signal strength resulting from each light source depends on the color and thickness of the body tissue, the sensor place- ment, the intensity of the light sources, and the absorption of the arterial and venous blood (including the time varying effects of the pulse) in the... -

Page 27: Patient Numbers And Spot Check Data
Chapter 3: Using the Oximeter Patient Numbers and Spot Check Data Whenever the oximeter is on, it stores one SpO and pulse rate reading every thirty (30) seconds. The stored readings are called spot check data. The oximeter remembers spot check data for up to ninety-nine (99) patients and seventeen (17) hours of run-time. -
Page 28: Turning Off The Oximeter
Chapter 3: Using the Oximeter Turning Off the Oximeter Press the “Q” key to turn off the oximeter. The oximeter turns off automatically two minutes after the sensor is removed from the patient or after the sensor is disconnected from the oximeter. - Page 29 This page is intentionally left blank.
