In a pulse oximeter light of two different wavelengths is passed through some limbs of the body, usually the finger tips or ear lobes, and is modulated by the pulsatile blood flow therein. The amplitude of the alternating current component generated by the processed light incident on the photo...
The invention relates to a pulse oximeter (100) comprising at least a first light source (110) and at least a first light sensor (120). Between the first light source (110) and the first light sensor (120) is a filter (130) for selection or absorption of light having wavelengths of ...
The pulse oximeter measured O2 saturation as 90%, and she had acral cyanosis. Electrocardiography revealed sinus tachycardia with a rate of 103/minute. Chest radiograph, complete blood counting, renal function tests and electrolytes were all in the normal range. Venous blood gas analyses revealed ...
Although these basic subsystems exist in any pulse oximeter, their implementation can vary significantly. In transmissive pulse oximeters, the photodiode is placed on the opposite side of the user's finger or earlobe from the LEDs. Commonly available finger clip units combine red, IR, and option...
The block diagram of the proposed low-cost portable pulse oximeter device is shown in Figure 1. It is made up of two input sensors, a microcontroller, batteries, and a single output device. MAX30100 is used to monitor the heart rate and the oxygen saturation (SpO2)...
