A Review on Design and Development of IoT Based Pulse Oximeter
Measuring the heart rate, oxygen saturation level and blood pressure plays a vital role in human body. In many critical condition measuring these parameters a very important when a patient is in critical condition so pulse oximeter is really necessary. Early pulse oximeter could only measure saturation level of oxygen. Later pulse oximeter evolved to measure pulse rate along with heart rate with temperature inbuilt control. Red and infrared sensors are used in pulse oximeter to detect heart beat and saturation level of the oxygen. In this paper pulse and saturation of oxygen can be calculated using different types methods that are easy and accurate to calculate. Alert system will alert the patients when there is drop of any level of the spo2 and heart rate.
