Implantation of a Boarding System for Supervision and Angulometric Tilt Adjustment of beds in the ICU of the Adriano Jorge Hospital Foundation in Manaus-AM

Concern about the high mortality rates in ICU beds in Brazil, as a result of the acquisition of Pneumonia associated with Mechanical Ventilation (PAV), triggered a series of movements in an attempt to establish procedures for its prevention. Studies indicate that the maintenance of decubitus between 30 ° and 45 ° of inclination, attenuates the invasive effects of mechanical ventilation equipment and promotes the favoring of diaphragmatic performance, significantly reducing the hospitalization time of patients submitted to mechanical ventilation. However, the Hospital Infection Control Committee (CCIH) of the Hospital Adriano Jorge Foundation (FHAJ), through its collaborators, found difficulties in the regulation of ICU beds, due to the lack of adequate measurement equipment for regulation. Through the implantation of an embedded system in Arduino microcontroller and the association of several components of sensing and communication, the development of the inclination measuring device became possible. Equipped with an alphanumeric LCD display and an Ethernet network module, the auxiliary supervision and adjustment device proved to be the solution for the decubitus regulation process, since besides allowing local real-time gauging and visualization, the module provided the sending of information to the Hospital's internal network (LAN), enabling general monitoring from the computer screen. With the built-in audible alert system for improper slopes, the correct angulation for PAV prevention could be maintained at optimal levels, eliminating human failures from carelessness and giving patients greater treatment safety.
