Abstract
Variable levels of positive end expiratory pressure (PEEP) are widely used during mechanical ventilation or during spontaneous breathing for acute or chronic lung diseases. In this study, respiratory indirect plethysmography (RIP), electromyography (EMG) of the transversus abdominis and scalene muscles and indirect calorimetry are used to achieve an integrated picture of the changes in the respiratory system after exposure to 10 cmH2O CPAP.
Highlights
Variable levels of positive end expiratory pressure (PEEP) are widely used during mechanical ventilation or during spontaneous breathing for acute or chronic lung diseases
Respiratory indirect plethysmography (RIP), electromyography (EMG) of the transversus abdominis and scalene muscles and indirect calorimetry are used to achieve an integrated picture of the changes in the respiratory system after exposure to 10 cmH2O continuous positive airway pressure (CPAP)
Fourteen young, healthy individuals participated in the study, assessed in the semi-recumbent position initially at ZEEP and at 10 cmH2O CPAP
Summary
To investigate the changes in breathing pattern, respiratory muscle mechanics and work of breathing induced by 10 cmH2O of continuous positive airway pressure (CPAP)
