Introduction: The maximum inspiratory pressure (MIP) is a representative of the overall strength of the inspiratory muscles index. Measuring the MIP is a simple, fast and non-invasive procedure widely used in clinical practice. No studies locally to assess the reliability of the measurement of the MIP. Objective: Determining the intra and inter-rater reliability of the measurement of MIP in 30 subjects Materials and methods: Descriptive study, conducted in the framework of a pilot-controlled clinical trial: Effects of Respiratory Muscle Training in adult patients on mechanical ventilation NCT02469064. Four evaluators made 3 PImax repeated measurements in 30 healthy subjects. For the evaluation of intra and inter rater reliability index intraclass correlation (ICC) general and each evaluator was calculated, the correlation between pairs of measurements were performed using Bland graphic Altmant. Results: The general ICC was 0.83 (95% CI 0.835 to 0.939). ICC values were 0.95 (95% CI .91-.97), 097 (95% CI 0.95 to 0.98), 0.95 (95% CI from 0.91 to 0.97), 0.91 (95% CI from 0.85 to 0.97) for evaluators 1.2, 3 and 4 respectively. The Bland Almant Figure showed adequate correlation between pairs of measurements MIP (p > 0.05). Conclusion: MIP proved to be a highly reliable measure, measurements were not affected by the order in which they were made for each subject, and basing its use in clinical practice.
