Resumen

Objective: The objective of this study is to determine the impact of the implementation of Total Productive Maintenance (TPM) on the availability of mechanical ventilators in the Intensive Care Unit of a public hospital. Methods: An applied research was carried out, employing a quantitative approach, using an explanatory level and a pre-experimental design. The population analyzed consisted of the weekly failure records of 20 mechanical ventilators. The aggregation of data was facilitated through the utilization of registration forms and checklists. Prior to the implementation of the intervention, indicators of availability, reliability, and maintainability were calculated. Subsequent to the intervention, a similar calculation was performed. Results: The availability rate exhibited an increase from 69.26% to 82.61%, signifying an enhancement of 19.26%. Reliability demonstrated a notable increase, rising from 19.13% to 28.52%, representing a substantial 49.05% growth. The maintainability index exhibited a significant decline, from 2.74% to 0.59%, representing a substantial 78.31% reduction. The statistical analysis yielded a p-value of 0.00, thereby confirming the positive effect of the MPR. Conclusion: The implementation of the TPM has been demonstrated to enhance the accessibility and functionality of mechanical ventilators within the intensive care unit (ICU), thereby serving as an effective strategy for optimizing the management of essential biomedical equipment.
