“…Patients completed spirometry tests before and after the administration of 400 μg of albuterol (a β 2 agonist bronchodilator), according to international guidelines 28 . Spirometric measurements were standardized as percentages of the predicted values by using established Chilean prediction equations 29 …”

“…In a study in which smokers were invited to switch to an e-cigarette and abstain from smoking, the FEF 25-75% increased significantly (p ¼ 0.034) from 85.7% to 100.8% predicted over 52 weeks (Cibella et al 2016). There are, however, several reasons why the FEF 25-75% may not be useful: it is dependent upon the FVC, it lacks the repeatability of FEV 1 , it has a wide normal range (Quanjer et al 2012b, Al Ghobain et al 2014, Balasubramaniam et al 2014, Gutierrez et al 2014, Rufino et al 2017 and it is reduced in the presence of proximal airway narrowing (Johns et al 2014). These drawbacks severely limit the use of FEF 25-75% for diagnostic purposes, but might not preclude its use in aetiological studies where differences between groups may be valuable.…”

“…Si bien la altura es un predictor importante de la función pulmonar (Gutiérrez et al;Lisboa et al, 2007;Donnolly et al), las dimensiones del tórax podrían ser mejores que la talla en bípedo (Donnolly et al; Peters et al). En el caso del FEM se utilizó, debido a su significancia estadística, el DTT a VR y el PME a CPT, esto tendría su explicación a través de la biomecánica de la prueba utilizada para medir esta variable; i) en una primera etapa se inspira hasta CPT; ii) posteriormente se produce un cierre glótico asociado a una contracción isométrica de los músculos espiratorios, aumentando las presiones intra-abdominal e intra-torácica; iii) consecuencia de esto, se produce un flujo espiratorio de alta velocidad, 11 a 12 L/s, hasta llegar a VR (McCool, 2006).…”

“…En este contexto, Gutiérrez et al (2014) definieron ecuaciones predictivas de función pulmonar en población chilena sana, en donde los valores derivados de estas fueron significativamente superiores a los de Knudson et al Por tanto, los investigadores sugieren la obtención de valores de referencia a partir de sujetos sanos, con características antropométricas similares a la población blanco.…”
