Energy Expedinture Measurement In Activities Of Daily Living Accomplished By COPD Patients

Abstract

There are no studies that have evaluated energy cost for COPD patients accomplishing the most common activities of daily Rationale living (ADL) Our aim was to develop a table with the energy and ventilatory costs of COPD patients accomplishing several common ADL.. Eighty COPD patients were analyzed by a portable ergoespirometer (K4 Cosmed) while performing 18 ADLs, during 5 minutes Methods: each: lateral lying, dorsal lying, sitting, standing, morning hygiene, bathing, put on and off clothes, put on and off shoes, domestic and office activities, going up and down a flight of stairs, walking for five minutes holding 2.5 Kg in each hand, walking for five minutes holding 5.0 Kg in one hand and go up and down a ramp.: Patient characteristics: mean age of 64.1±10.2 yrs, FEV /FVC of 0.48±0.12 and Results 1 FEV of 55.9±23.2%. 1 *p<0.05, pre vs. post activity.: Simple activities of daily living performed by COPD patients lead to a high ventilation (up to 65% of the ventilatory reserve), Conclusion cardiac requirement (up to72% of the cardiac reserve) and energy cost (up to 50% of maximum estimated VO2 or 2-4 times the rest value).
