Abstract

Hypothermia is a state where the body cannot balance the body heat due to excessive cold temperature pressure so that there will be loss of heat in the body. The result will be a quickly decreasing body temperature. A condition where a body temperature is less than 35°C and that it is accompanied by a decrease in consciousness may cause a death threat. Hypothermia is more common when climbers perform activities in cold temperatures and strong winds, and when they wear wet clothes. It is not easy for a mountain climber to find out his own body temperature as well as that of his friends and to determine whether the body temperature is safe or affected by hypothermia symptoms. Therefore, this research formed a device to detect hypothermia. It consists of temperature sensor, pulse sensor, and accompanied by heating elements based on wireless body area network (WBAN). This device will connect to the user’s smartphone by using Bluetooth, so the user can see the condition of his body, adjust the temperature of the heating element, and make a group of climbers. The experiment result shows that the device can detect hypothermia symptoms and inform these symptoms to the users and groups of mountaineers in WBAN area, and the climbers can be more vigilant in responding to hypothermia so that mortality cases caused by hypothermia can be minimized.

Highlights

  • Hypothermia is a condition in which the body's mechanism for temperature regulation has difficulty coping with cold pressure

  • Digital body thermometer was used to measure the difference of temperature value from body temperature sensor MLX90615

  • The body temperature sensor MLX90615 and digital thermometer were placed in the same position and would count the temperature of the body simultaneously

Summary

Introduction

Hypothermia is a condition in which the body's mechanism for temperature regulation has difficulty coping with cold pressure. Hypothermia can be defined as an internal temperature below 35°C. The human body can regulate temperature in the thermo neutral zone, which is between 36.5-37.5°C. The body's response to regulating temperature will actively balance heat production and heat loss in the body. Hypothermia often occurs when climbers are in extreme environments, especially cold temperatures, and due to the health factor of climbers [1]. Extreme situations in climbing environments such as cold air pressure due to high mountains, strong winds blowing, wet clothes, and other extreme factors make hypothermia become a common disease in the climbing areas [2,3]
