| Research Abstract |
Respiratory muscle function largely affects prognosis of critically ill patients received mechanical ventilation. We examined methods of assessing tension of respiratory muscle and factors related to respiratory muscle function during mechanical ventilation. Patient's level of consciousness affected tensions by voluntary efforts. It was difficult to determine the site of stimulation in ICU patients in percutaneous stimulation for phrenic nerve. Effects of sedatives and mode of mechanical ventilation on assessment of respiratory muscle function were studied. Imposed expiratory work of breathing during mechanical ventilation and the relationship between renal failure and respiratory failure were also examined. The results were considered to be useful respiratory care to preserve respiratory muscle function.
