The degree of dynamic hyperinflation can be assessed by measuring reduction in inspiratory capacity (IC). The aim of this study was to establish reference values for IC in healthy individuals of both sexes between the ages of 50 and 87 years, as such data are scarce in the literature.</p> <span class="elsevierStyleSectionTitle">Subjects and methods</span><p class="elsevierStyleSimplePara elsevierViewall">We studied 155 healthy volunteers (93 women) with normal spirometry. None had a prior history of respiratory, cardiovascular, or systemic diseases that might alter lung function. All were never-smokers. IC was measured during a normal, unforced inspiration to total lung capacity starting from functional residual capacity. The highest value of 6 satisfactory maneuvers was recorded. Sex, height, age, and weight were included in the regression equations. One thousand bootstrap samples for each sex were also analyzed.</p> <span class="elsevierStyleSectionTitle">Results</span><p class="elsevierStyleSimplePara elsevierViewall">For each sex, we found that a model including age, height, and weight produced IC prediction equations with a coefficient of determination (<span class="elsevierStyleItalic">r</span><span class="elsevierStyleSup">2</span>) of 0.414 for women and 0.447 for men. The mean (SD) intrasubject coefficient of variation was 4.3% (2%) for IC measured during a single session and 5.1% (0.4%) for measurements from 5 weekly sessions.</p> <span class="elsevierStyleSectionTitle">Conclusions</span><p class="elsevierStyleSimplePara elsevierViewall">Our results provide reference equations for IC that are valid for a healthy population over 50 years of age.

Nuestro objetivo ha sido establecer valores de referencia de la CI en individuos sanos de ambos sexos, de entre 50 y 87 años de edad, debido a que en la literatura médica disponible prácticamente no se ofrecen tales datos.</p> <span class="elsevierStyleSectionTitle">Sujetos y métodos</span><p class="elsevierStyleSimplePara elsevierViewall">Estudiamos a 155 voluntarios sanos (93 mujeres), que nunca habían fumado ni presentaban antecedentes de enfermedades respiratorias, cardiovasculares o sistémicas que pudieran alterar la función pulmonar, y cuya espirometría era normal. La CI se midió durante una inspiración no forzada hasta la capacidad pulmonar total a partir del valor en reposo espiratorio, y para los resultados se empleó el valor más alto de 6 maniobras satisfactorias. En las ecuaciones de regresión se incluyeron el sexo, la talla, la edad y el peso.
