Resumen

The increase in the number of people suffering from respiratory system diseases is related to environmental pollution. Pulse oximetry equipment, which measures blood saturation levels, is of great importance in the evaluation of patients with respiratory disorders. Oxygen levels and other vital signs are important indicators of an individual's health. Monitoring these signs can help protect against health problems. Historically, measuring blood oxygen levels has been difficult and time-consuming. Often, it is not possible to do so during risky situations, such as during surgeries. That said, current methods are much more accurate and can be used to monitor patients in a variety of situations, but are relatively expensive, depending on the equipment and its performance. In the present work, a pulse oximetry module is designed and implemented using a low-cost acquisition card, the NIDAQ USB 6008, to perform noninvasive measurements in hospitalized patients as well as at home. The assembly has the advantage of avoiding failures due to physical maintenance, integrated circuit cabling and/or calibration. Due to its connection to a computer, the data obtained can be contrasted with other vital signs obtained in other hospital centers so that the information can be shared by experts in emergency situations.
