oxide to avoid the risk of explosion.
15.Caution,When using this product, you only need to fix it on your fingers.
Excessive pressure on your fingers may cause skin damage.
16.The maximum skin surface temperature is below 41℃(106℉) when measured in
a 35℃(95℉)environment, which has been verified by measuring the skin surface
temperature via a Finger Pulse Oximeter under the reasonable worst conditions.
17.Please pay attention to product storage to prevent damage caused by pets, pests or
children.
Performance:
18. Warning, Do not self-diagnose or self-medicate based on measurement results.It
must be used in conjunction with other methods of assessing clinical signs and
symptoms.
19.Warning, Do not use the the finger pulse oximeter in situations where alarms are
required. The device has no Alarm System.
20.The effect of sensor and electrode degradation or electrode loosening may reduce
the performance of the measurement or cause other problems.
21. Warning,The thickness of the little finger may be smaller than the minimum size
range for which this product is designed, so we recommend using index finger,
middle finger and ring finger instead of small finger.
22. Warning, Do not use the oximeter if it shows signs of damage or is suspected of
being damaged. Inaccurate or no readings may result from internal damage.
23. Warning, Avoid the following to reduce the risk of SpO2 inaccuracy:
（
1
）
Improper placement of the oximeter.
（
2
）
Significant levels of dysfunctional hemoglobin (such as carbonyl hemoglobin
or methemoglobin);
（
3
）
Blood vessels contain dyes (such as indigo green or methylene blue).
（
4
）
External paints and substances (e.g. nail polish, nail polish, glitter, etc.).
（
5
）
The user is wearing a high-pressure cuff when measuring.
（
6
）
Avoid placing the oximeter on any arm with an arterial cannula or blood
pressure cuff.
（
7
）
Elevated bilirubin levels. Severe anemia.
（
8
）
Venous congestion. Venous pulsation.
（
9
）
Arterial perfusion levels are extremely low.
（
10
）
Excessive physical activity.
（
11
）
During cardiac arrhythmia.
24.Warning, Keep the oximeter away from electrical equipment that emits radio
frequencies to minimize radio interference. RF may result in inaccurate or inaccurate
readings.
25.Warning, Properly apply and avoid using the oximeter in strong ambient light
sources, fluorescent lights, infrared heat lamps, and direct sunlight to minimize
interference that may result in unreadable or inaccurate readings.
