Monitoramento de Ventilação Mecânica: Estudo de Caso sobre Capnografia e Proposta de Implementação de um Capnógrafo para Acionador Automático de Ambu

Abstract

During the COVID-19 pandemic, the demand for mechanical ventilators increased due to the significant number of patients with respiratory failure. However, instances of power outages highlighted the vulnerability of patients dependent on these vital devices, leading to the search for alternatives such as the manual resuscitator. Due to the difficulty in maintaining precise frequency and the physical fatigue associated with this procedure, the need for more efficient solutions became apparent. Thus, the Automated Ambu Actuator (AAA) emerged, automating the process of pulmonary ventilation with parameter adjustment according to the patient's needs. To enhance the monitoring of this device, a study is proposed for the development of a capnograph module. This capnograph, composed of an infrared emission system and sensors connected to a collection tube adapted with nasal cannulas, aims to monitor the quantity of carbon dioxide in the exhaled air by the patient. Such data is crucial for assessing the effectiveness of breathing and pulmonary ventilation. The implementation of this capnograph in the AAA has the potential to significantly enhance monitoring and treatment efficacy, providing precise data during mechanical ventilation.
