Fingertip Pulse Oximeter · 型号 BSX231
RocSea means that blood saturation (SpoO2) and pulses can be measured within 8 seconds at the same time and are suitable for routine family haemooxin monitoring, highland travel and respiratory health management. All you have to do is insert your finger in a finger clip and keep your still. The OLED screen is shown in four directions, and the extraction point automatically turns off the power.

Pyramid pulse oxidation is calculated for haemorrhagic saturation (Spo2) and pulse by measuring the absorption differences between haemoglobin and oxyglobin erythroglobin on the light by means of a double wavelength (660 nm red / 905 nm infrared). The whole process is in pain, in eight seconds.
Use soft cloth to wipe the inside and the outer casings with a small amount of alcohol to avoid water intrusion and fall; no batteries are removed for long periods of time.
Healthy adults are generally 95 per cent - 100 per cent at sea level at static levels; less than 93 per cent continue to be recommended for medical treatment. The values are naturally low in the highland environment.
The common cause is cold fingers, nail polish, hand shaking or inappropriate placement. Keep your hands warm, remove nail polish, and remain still until you detect it.
The normal use is approximately 20-24 hours (2 new AAA alkaline batteries) and should be replaced in a timely manner when a low-power tip appears on the screen.
