Estudio del estado funcional y determinación de la vida útil de máquinas de anestesia en el bloque quirúrgico de un hospital de tercer nivel en Guayaquil

Abstract

This study delves into evaluating the functional state and determining the lifespan of anesthesia machines at a third-level hospital in Guayaquil, employing a methodology that integrates technical, economic, and clinical analysis tailored to the hospital's specific needs. The research revealed that 59.32% of the identified failures are pneumatically related, highlighting the importance of adequate preventive maintenance. It was found that Mindray anesthesia machines exceed the recommended limit of corrective maintenances, suggesting suboptimal maintenance management compared to General Electric machines, which present an almost ideal ratio between preventive and corrective maintenances. Detailed analyses demonstrated how specific defects in critical components like oxygen and flow sensors, as well as O-rings, directly impact the equipment's functionality, affecting the safety and efficiency of the administered anesthesia. Using the obsolescence methodology, the effective lifespan of each machine was determined, ix ranging from 14 to 17.5 years. This approach allowed for the classification of machines according to their life stage and failure rate, recommending medical technology evaluations at specific intervals to ensure optimal operation. The study's conclusion underscores the need for proactive technological management and strategic planning in the renewal and acquisition of medical equipment. It highlights the importance of adopting a maintenance regime that prioritizes preventive over corrective interventions, thus ensuring the continuity and quality of medical care. The results provide a solid foundation for informed decisions regarding the management of anesthesia machines, significantly contributing to resource optimization and the improvement of health services at the hospital.
