Abstract
The LifeShirt System (VivoMetrics)is a non-invasive, continuous ambulatory monitoring system collecting ventilatory data during a subjects daily activities. We aimed to study the effect of aerobic exercise training on ventilatory parameters in moderate IIA COPD subjects (GOLD) both at rest and during standardized physical activity. 6 patients have been recruited from our outpatients clinic. 1day: patients performed complete respiratory function test and cardiopulmonary exercise test by bicycle ergometer (10 watt/min increment). 2day Lifeshirt data were collected during 60 rest and during 30 moderate physical activity (walking) at 70% maximal heart rate (HR)achieved during exercise test (CPET). Thereafter patients started a 12 weeks domicilary programm of aerobic exercise training walking 30 x 3times/week at 70% maximal HR achieved CPET. After the conclusion of the programm, Lifeshirt monitoring has been repeated in the same way. VE during CPET at 70% HR 23,1(4,1) not different from Lifeshirt VE.A significant optimization of ventilatory parameters during exercise has been found after the training programm. We conclude 1. aerobic exercise training is useful to optimize the ventilatory response in COPD patients. 2 the possibility of continuously monitoring ventilatory data during daily activities can give useful information on patientsventilatory response.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
