Summary<\/strong><\/p>\n<\/blockquote>\n

This study describes the design, simulation, and validation of an automated mechanical ventilator system using neural networks to optimize critical ventilation parameters. The ventilator specifically addresses clinical conditions such as pneumonia and chronic obstructive pulmonary disease (COPD). By employing feed-forward neural networks (FFNN) to regulate parameters like tidal volume, respiratory rate, and inspiration-to-expiration (I:E) ratio, the ventilator demonstrated optimal performance and adaptability to different respiratory scenarios. The proposed system aims for cost-effectiveness, stability, and enhanced precision, making it potentially transformative in resource-constrained healthcare settings.<\/p>\n
