Summary

Acute exacerbations of COPD contribute to significant morbidity and mortality in the United Kingdom (UK). The ability to assess response to treatment during exacerbations that require hospitalisation would allow clinicians to better risk stratify patients for higher or lower level in-patient or out-patient care. Current methods of detecting clinical deterioration are validated in general medical populations and may lack sensitivity and specificity in patients with respiratory morbidity. The use of respiratory muscle EMG to assess neural respiratory drive (NRD) has been demonstrated to be a predictor of readmission in patients admitted to hospital with COPD. The technique has been applied on 'spot' readings of limited duration due to the need for hand analysis of the data. It has been performed by a trained clinical physiologist who removed any interference data and standardised the data gathered. New automated software allows for longer periods of observation, mostly unsupervised, and as a result, the NRD measurements are more likely to be affected by various sources of variability. The influence of clinical and physiological factors as they occur during routine clinical management, such as administration of bronchodilator medication, time of day of readings or proximity to chest physiotherapy, are not yet understood. This trial is designed to gather data to better understand these relationships with NRD.

Interventions

OTHER

Neural Respiratory Drive Automated EMGpara assessment

Neural respiratory drive will be measured using surface electrodes and nasal cannula . The 2nd intercostal space will be identified by bony landmarks and skin preparation will be performed using detergent wipes, followed by EMG preparation gel with final cleaning to remove exfoliated skin. Wet gel electrodes will be placed immediately adjacent to the sternal border in the 2nd intercostal space and will be connected to the automated EMG analysis system. Electrodes will remain in place for the duration of the study. A nasal cannula will be placed in the nose and detect pressure changes during respiration in order to ensure accurate detection of inspiratory cycle. In addition, an accelerometer will be attached to the thorax of the patient
