Resumen

Se ha determinado la relación volumen-presión inspiratoria estática máxima (V/PImax) en 18 sujetos (cuatro normales, siete con restricción toracógena mecánica y siete con neuromiopatías diversas que afectaban a los músculos respiratorios). Los sujetos normales fueron reestudiados tras un strapping torácico a nivel de RV. La PI-males tras el strapping de forma proporcional a la males tras el strapping de forma proporcional a la pérdida de volumen. Los sujetos con restricción mecánica se comportaron de forma similar a los normales post-strapping. Los sujetos con neuromiopatías presentaron una afectación de la PI-max (FRC) comparativamente superior a la pérdida de volumen.

La PImax (FRC)c = PImax (FRC teórica/TLC real permite una mejor discriminación de los sujetos con restricción ventilatoria de origen neuromiopático, que la alteración de volúmenes o la PImax (FRC) en orden absoluto.

Summary

The volume-maximal static inspiratory pressure (V/PImax) relation was determined in 18 subjects (4 normal ones; 7 with mechanical thoracic restrictive disease; 7 with different neuromyopathies affecting the respiratiry muscles). The normal subjects were also studied after thoracic atrapping at RV level; PImax decreased at FRC level after strapping and proportionally to the loss of volume. Findings for the subjects with mechanical restriction were similar to those for the normal subjects after strapping. The subjects with neuromyopathies presented a PImex (FRC) affectation comparatively higher than the loss in volume.

PImax (FRC) adjusted to TLC:

PImax (FRC)c = PImax theoretical TLC/true TLC; allows a clearer recognition of patients with restrictive ventilatory neuropathy, than do volume alterations or absolute PImax (FRC).
