Compartmental chest wall volume changes during volitional hyperpnoea with constant tidal volume in healthy individuals.
Prolonged high-intensity ventilation is associated with the development of rapid shallow breathing with decreased end-inspiratory volumes of all chest wall compartments. During respiratory muscle endurance training using normocapnic hyperpnoea, tidal volume (V(T)) is normally kept constant. The aim of this study was to investigate possible changes in muscle recruitment during constant-V(T) hype...
متن کاملPatients with acute spinal cord injury benefit from normocapnic hyperpnoea training.
BACKGROUND Functional loss of respiratory muscles in persons with spinal cord injury leads to impaired pulmonary function and respiratory complications. In addition, respiratory complications are responsible for 50-67% of the morbidity in this population. OBJECTIVE To investigate the effects of normocapnic hyperpnoea training in acute spinal cord injury. PATIENTS AND METHODS Fourteen patien...
متن کاملChest wall motion during tidal breathing.
We have used an automatic motion analyzer, the ELITE system, to study changes in chest wall configuration during resting breathing in five normal, seated subjects. Two television cameras were used to record the x-y-z displacements of 36 markers positioned circumferentially at the level of the third (S1) and fifth (S2) costal cartilage, corresponding to the lung-apposed rib cage; midway between ...

متن کاملChest wall mechanics during pressure support ventilation
INTRODUCTION During pressure support ventilation (PSV) a part of the breathing pattern is controlled by the patient, and synchronization of respiratory muscle action and the resulting chest wall kinematics is a valid indicator of the patient's adaptation to the ventilator. The aim of the present study was to analyze the effects of different PSV settings on ventilatory pattern, total and compart...
