ABSTRACT Background Airflow limitation frequently leads to the interruption of activities of daily living (ADL) in patients with Chronic Obstructive Pulmonary Disease (COPD). These patients commonly show absence of ventilatory reserve, reduced inspiratory reserve volume, and dynamic hyperinflation (DH)....
Abstract Objective: The purpose of this study was to evaluate the effect of a cycle ergometer exercise program on exercise capacity and inspiratory muscle function in hospitalized patients with heart failure awaiting heart transplantation with intravenous inotropic support. Methods: Patients awaiting h...
OBJECTIVE: To assess the influence of diaphragmatic activation control (diaphC) on Sniff Nasal-Inspiratory Pressure (SNIP) and Maximum Relaxation Rate of inspiratory muscles (MRR) in healthy subjects. METHOD: Twenty subjects (9 male; age: 23 (SD=2.9) years; BMI: 23.8 (SD=3) kg/m2; FEV1/FVC: 0.9 (SD=0.1)...
Inspiratory and expiratory muscle strength (MIP and MEP) assessment, and peak expiratory flow (PEF) and peak cough flow (PCF) measurements are often used to assess patients with respiratory diseases. Notwithstanding, there are few reports about reliability of these measurements. The aim of this study is ...
En 10 pacientes portadoras de artritis reumatoide se evaluó la fuerza global de la musculatura inspiratoria a través de la presón inspiratoria máxima (PIM). Seis sujetos presentaron alteraciones radiológicas pulmonares, 6 manifestaciones de tos y 2 de disnea. La PIM resultó significativamente dismi...
Estudiamos 20 pacientes con OBC (VEF1/CVF 37 . 3 porciento) que fueron asignados en forma aleatoria y doble ciego a EMI por 10 semanas con una válvula umbral, empleando un 30 porciento (grupo 1) o un 10 porciento (grupo 2) de la PIMax como carga de entrenamiento. Los cambios en la disnea se evaluaron co...
Para evaluar el efecto de la exposición intermitente a un ambiente de hipoxia hipobárica en la fuerza y resistencia a la fatiga de los músculos inspiratorios, estudiamos 51 sujetos (edad promedio de 31ñ8.6 años) que trabajan en una mina de oro situada en el norte de Chile mediante un esquema de jorn...
