Protótipo de um monitor multiparâmetro para electrocardiograma e temperatura corporal

Abstract

Thanks to the technological advance in the health area that has occurred in the last decades, the real-time monitoring of patient's parameters is a reality today. In this sense, the electrocardiogram (ECG) was included among the most recommended monitoring standards in the world, being useful in several procedures both general and local, anesthesia techniques, including sedation procedures among others. The popularity gained among clinicians is due to some characteristics: non-invasive, moderate cost, simplicity of operation, continuous nature and minimum risk for the patient. The temperature of the human body is the result of the balance between production and the expenditure of heat, which is precisely controlled by a small area at the base of the brain (hypothalamus). Heat production derives from vital activities (eg, breathing, cardiac contractions, circulation, secretions) and from exertion or muscle exercise and chills. The body temperature is maintained at normal conditions around 37 ° C and varies during the day between 36.8 ° C in the morning and 37.3 ° C at the end of the day, decreasing during sleep. Hypothermia is a decrease in body temperature below 35 ° C. Maintaining core body temperature ensures normal physiological and metabolic functioning. The elevation of body temperature (hyperthermia) is a defense tool used by the body to indicate that something is wrong in the patient's body. Thus, this work deals with the development of a prototype of an electrocardiogram monitor and body temperature. The device created consists of two main parts: (1) Software developed in the C # language using concurrent programming to display in real time the monitored variables, also allowing the insertion of more parameters in a possible continuity of this work. (2) Hardware used for signal capture and filtering: Cooking Hacks e-Health Sensor Shield V2.0 platform for Arduino. The parameters provided by the prototype were compared to their values measured on a commercial multi-parameter monitor, brand Omnimed model Omni 610. The results obtained with the prototype developed were quite similar to the commercial equipment described.
