NantLife Smart Pulse Oximeter is intended for spot-checking in measuring and displaying functional arterial oxygen saturation (SpO2) and pulse rate in the home. It is intended for adult and pediatric patients on finger between 0.3-1.0inch
(0.8-2.5cm) thick. Never change your medication on the basis of results you have obtained. The treating physician may only carry out the evaluation of the measure-
ments and the treatment based on them. The NantLife Smart Pulse Oximeter is not intended to be a diagnostic device. This device is intended for use in measuring oxygen saturation in blood pres-
sure and pulse rate in the adult and pediatric population. Do not use this device in infants or person who cannot express their intention. 1.3 Safety Information To assure the correct use of the pulse oximeter, basic safety measures should always be followed including the warnings and cautions lifted in this instruction manual. 5 English 1.3.1.1 Warnings Read all of the information in the instruction manual and any other instruction in the box before operating the unit.

Measurements may be affected by dyes such as indocyanine green and methylene blue. Measurements may be affected by upper ambient light (e.g. direct sunlight). Excessive user movement may cause inaccuracy. Upper-frequency electro-surgical readings. Venous pulsations may cause inaccurate readings Placement of Pulse Oximeter on an extremity with a blood pressure cuff, arte-
rial catheter, or intravascular line may cause inaccurate readings. Users with hypotension, hypothermia may cause inaccuracy. Autoclaving, ethylene oxide sterilizing, or immersing the pulse oximeter in liquid may cause inaccurate measurements. Excessive user movement may cause inaccurate readings All NantLife devices are designed to be compliant with rules and regulations in locations they are sold and are labeled as required. Any changes or modifications to NantLife equipment, not expressly approved by NantLife void the users authority to operate the device. severe vasoconstriction, anemia, and/or 8 1.4 Before taking a measurement General information about oxygen saturation in blood:
Your oxygen saturation in blood fluctuates throughout the day. Hypoxemia, or low blood oxygen, describes a lower than normal level of oxygen in your blood. In order to function properly, your body needs a constant level of oxygen circulating in the blood to cells and tissues. When this level of oxygen falls below a certain amount, hypoxemia occurs and you may experience shortness of breath. Your doctor determines whether you have hypoxemia by measuring your blood oxygen level the amount of oxygen traveling in your arteries. Your blood oxygen can be measured by testing a sample of blood from an artery.
(Resource: Mayo Family Health Book, Fourth Edition) NantLife pulse oximeter, a small device that clips on your finger, measures the saturation of oxygen in your blood; the results are often used as an estimate of blood oxygen levels. Normal pulse oximeter readings range from 95 to 100 percent, under most circumstances. Values under 90 percent are considered low. If you monitor your blood oxygen regularly, you will discover more about your bodys reactions to external influences (e.g. stress, air pollution or exercise), and you will be able to consciously develop a healthier lifestyle. 9 English Your healthcare providers want to get an accurate picture of your blood oxygen lev-
els and chart what happens over time. Your doctor will evaluate the data you have stored, once you share it with her/him, and will immediately have a better overview of the course of your blood oxygen measurements. You will be controlling and sup-
porting the monitoring of your doctors treatment. Avoid eating, drinking alcohol, smoking, exercising, and bathing for more than 30 minutes before taking your measurement. Rest for 10 minutes before taking the measurement. Do not take measurement during stressful times. Remain still during measurement. Try to measure your oxygen saturation in blood at about the same time every day for consistency. 10 2 Operating Instruction 2.1 Know your NantLife Smart Pulse Oximeter OLED display One Touch Button Finger Probe Batteries Compartment 11 English 2.2 Unit Display Pulse rate beats per minutes Wireless Transmission Signal Low Power Indicator Percentage of oxygen saturation in blood 12 2.3 Display Symbols Symbols Sp02%
