Online sphygmomanometer chip mainly consists of:

1. A microprocessor, memory (EPROM and RAM), two digital to analog converters that control LEDs, devices that stop filtering and amplifying signals received by photodiodes, and analog-to-digital converters that digitize the received signals to provide the corresponding microprocessor. LEDs and photodiodes are placed in small probes that come into contact with the patient's fingertips or earlobes. The pulse oximeter generally also includes a small LCD display;

2. Appearance: Similar to a needle tube, with a moderate appearance. Using bento is a necessity for the demand group.

　　SphygmomanometerThe main measurement indexes were pulse rate, oxygen saturation and perfusion index (PI). Oxygen saturation (SpO2 for short) is one of the fundamental data in clinical medicine. Oxygen saturation refers to the percentage of the separated O2 volume in the total separable O2 volume.

The first oneSphygmomanometerPublished by Millikan in the 1940s. It monitors the ratio of oxygen carrying hemoglobin to non oxygen carrying hemoglobin in the arteries. typicalSphygmomanometerEquipped with two light-emitting diodes. These two light-emitting diodes face the patient's test area - usually the fingertip or earlobe. One diode emits a beam of light with a wavelength of 660 nanometers, while the other emits 905910 or 940 nanometers. The absorption rates of oxygen-containing hemoglobin at these two wavelengths differ greatly from those without oxygen. By applying this property, the ratio of two types of hemoglobin can be calculated. The testing process usually does not require blood to be drawn from the patient.

The level of blood pressure is a reflection of a person's overall physical fitness, and an oxygen saturation of over 95% is the normal level of the human body. So what is blood pressure saturation? Simply put, blood pressure saturation is a newly established indicator in the medical community to weigh the health of the human body.
