Se midieron las presiones inspiratorias máximas estáticas (pico y meseta) —PIM— en diez sujetos normales. Las medidas fueron repetidas 6 veces a lo largo de 6 semanas consecutivas. Se observó un aumento estadísticamente significativo a partir de la cuarta determinación en la presión pico y de la sexta en la presión meseta. La presión pico y la presión meseta se comportaron siempre de un modo similar siendo su diferencia prácticamente constante a lo largo de las seis semanas. En consecuencia, creemos que para una interpretación correcta de la PIM debe de tenerse en cuenta el efecto aprendizaje. Con fines prácticos la presión pico puede ser usada para medir la función muscular al igual que la presión meseta.

Static maximum inspiratory pressures (peak and plateau —PIM— were measured in ten normal healthy subjects. Measurements were repeated six times over a 6 consecutive weeks period. Peak pressure showed a statistically significant increase from the fourth measurement onwards while plateau pressure appeared significantly greater at the sixth measurement. Peak and plateau pressures showed a similar behaviour with an almost constant difference over the six weeks period. From these results we believe that the training effect should be taken into account in order to get a right interpretation of PIM. For practical purposes, both peak pressure and plateau pressure may be used in the assessment of muscular function.
