Determination of Relaxed and Hypoventilation Body Conditions using Pulse Oximetry and Temperature Measurements

This paper focuses on the study of relaxed and hypoventilation body conditions using pulse oximetry and temperature measurements. An Arduino-based portable pulse oximeter and temperature measurement device is developed to monitor these biomedical signals. Pulse oximetry is a non-invasive method for accurately estimating oxygen saturation (Sa02) level by reading the peripheral oxygen saturation (Sp02). A thermistor is used to measure body temperature. The Arduino microcontroller is used for signal extraction and processing. The measurements were acquired using two conditions: relaxed state and hypoventilation state. The relaxed state serves as the control group while the hypoventilation state is used to simulate the condition of hypoxemia which is a state of abnormally low level of oxygen.
