Ventilador mecânico pulmonar
Abstract in Portuguese
Este trabalho visou mostrar o desenvolvimento de um ventilador pulmonar mecânico, focando principalmente na parte de hardware necessária para que este equipamento pudesse funcionar. Ventilação mecânica é a modalidade da medicina mais importante no cuidado a pacientes criticamente enfermos. O ventilador é um equipamento utilizado principalmente em unidades de terapia intensiva, que basicamente coloca uma mistura de ar e oxigênio para dentro do pulmão de um paciente incapacitado de fazer isto naturalmente, quer seja por força de uma doença que o impossibilita de fazê-lo, ou por uma cirurgia, a qual impossibilitou o movimento do músculo do diafragma para que o ar entrasse no pulmão naturalmente. Este projeto cobriu uma descrição abrangente sobre este ventilador, sua transformação de ar comprimido e oxigênio provenientes de um cilindro em uma mistura controlada de fluxos que entra no pulmão para a inspiração de um volume, ou para atingir uma pressão determinada, e a saída desta mistura, mantendo no pulmão uma pressão também controlada. Foi desenvolvido um protótipo de hardware e firmware para este aparelho, e o intuito foi mostrar o processo de transformação da ideia inicial e as necessidades de projeto em um aparelho testado e certificado para uso no mercado.

Pulmonary mechanical ventilator
Abstract in English
This work aimed to present the development of a pulmonary mechanical ventilator, mainly focusing on the hardware part needed in order for this device to work. Mechanical ventilation is the most important medical mode concerning the care of patients that are critically ill. The ventilator is a device very much used in intensive care units (ICUs), and it basically delivers an air and oxygen mixture to the patients lungs that is normally unable to do so naturally, either because the patient is seriously ill that prevents him/her to do so, or due to surgery, in this case prevented the movement of the diaphragm muscle so the air could be naturally delivered to the lung. This work covered a comprehensive description about this ventilator, its transformation of compressed air and oxygen coming from a cylinder in a controlled mixture of flows that enters the lung for the inspiration of a volume, or to achieve a determined pressure, and the output of this mixture, maintaining a controlled pressure in the lung too. A hardware and firmware prototype was developed for this device. The aim was to show the transformation process from the main idea and the need for a project of a tested and certified device to be used in the market.
