Os ventiladores mecânicos desempenham um papel fundamental para a manutenção da
respiração de pacientes que apresentam alguma deficiência respiratória, seja esta transitória
ou permanente. O aparecimento da pandemia Covid-19, provou a enorme importância e
agilidade destes equipamentos, uma vez que estes são capazes de salvar vidas ao garantirem a
ação primordial, que é a respiração para o ser humano.
A escassez de ventiladores, durante a pandemia, conduziu ao aparecimento deste projeto, que
vai permitir a exploração das funcionalidades do PLC S7-1200, aplicando-as a um ventilador
invasivo acionado eletricamente. Demonstra-se assim que a automação pode desempenhar um
papel importante mesmo em áreas para além da indústria.
Foi desenvolvido o controlo do ventilador invasivo, com controlo por tempo, e uma válvula
PEEP elétrica, com controlo em malha fechada, recorrendo-se a um controlador PID.
O ventilador elétrico e a válvula PEEP poderão ser comandados localmente, através da HMI
KTP700 da Siemens, ou à distância através de uma página web. Sendo que só se poderá
enviar comandos, através da página web, quando o ventilador não estiver a ser comandado
localmente, garantindo assim segurança na ventilação mecânica.
A monitorização dos ventiladores é bastante importante, uma vez que, permite aos
profissionais de saúde uma análise da ventilação minuciosa, minimizando assim riscos de
lesões pulmonares induzidos pelo uso inadequado dos ventiladores. Dado à enorme
importância da monitorização foram desenvolvidas várias interfaces para este efeito
permitindo aos profissionais de saúde monitorizarem o ventilador localmente e à distância.
Portanto o profissional de saúde poderá monitorizar o ventilador localmente através da HMI
KTP700 ou à distância através da página web. Utilizou-se o OPC UA para se poder aceder
graficamente aos dados no Matlab/Simulink.
Elaborou-se um registo de dados com a data/hora, fluxo e pressão, onde de seguida este
registo será enviado em anexo por e-mail. Também serão enviados alarmes/erros por e-mail.
Por último, foi criada uma base de dados que permite uma análise futura às grandezas pressão
e fluxo, que poderão ser filtradas por paciente.
ABSTRACT: Mechanical ventilators play a fundamental role in maintaining the breathing of patients with some respiratory deficiency, whether transient or permanent. The appearance of the Covid-19 pandemic proved the enormous importance and agility of these equipments, since these are capable of saving lives by ensuring the primordial action, which is breathing for the human being. The shortage of ventilators during the pandemic led to the emergence of this project, which aims to explore the functionalities of the PLC S7-1200, applying them to an electrically powered invasive ventilator. Thus demonstrating that automation can play an important role even in areas beyond the industry. Was developed the invasive ventilator control, with by time-control, and the electric PEEP valve, with closed-loop control, using a PID controller. The electric ventilator and PEEP valve can be controlled locally via Siemens HMI KTP700 or remotely via a web page. You can only send commands, through the web page, when the ventilator is not being commanded locally, thus ensuring safety in mechanical ventilation. The monitoring of ventilators is quite important, since it allows health professionals a thorough ventilation analysis, thus minimizing risks of pulmonary lesions induced by inadequate use of ventilators. Given the enormous importance of monitoring, several interfaces have been developed for this purpose allowing health professionals to monitor the ventilator locally and remotely. Therefore, the healthcare professional will be able to monitor the ventilator locally via HMI KTP700 or remotely via the website. OPC UA was used to be graphically able to access the data in Matlab/Simulink. A data log has been prepared with the date/time, flow and pressure, where then this record will be sent in an e-mail. Alarms/errors will also be sent by email. Finally, a database was created that allows a future analysis of the pressure and flow quantities, which can be filtered per patient.
