Filter by:Study Title Exploring patterns of speech and breathing to indicate the presence of obstructive respiratory disease. Study Design Prospective Case Control Study Study Participants Participants will be patients attending the respiratory physiology clinic at the Cardiopulmonary Unit, Prince Charles Hospital for an assessment of their lung function. In addition a cohort of control participants without obstructive respiratory disease will be recruited with the assistance of the British Lung Foundation charity. Planned Size of Sample (if applicable) We have received funding for 52 ½ day sessions and we plan to recruit on average 2 participants per session. As such we aim to recruit a minimum of 100 participants. In addition we are working with the British Lung Foundation to recruit a smaller Cohort of control participants and aim to recruit a minimum of 25 control participants. Planned Study Period Jan 2019 - Aug 2019 Research Aim(s) This primary objective of this novel study it to create an anonymised database of speech patterns of patients with chronic respiratory disease and healthy aged matched controls for comparison with lung function and medical history. The primary aims are to: - Collect breathing patterns from individuals under a range of talking modalities - Understand how easy it is to gather short speech recordings - Explore the preferences of patients to be recorded talking
Up to 60% of patients with heart failure show abnormal patterns of breathing (sleep disordered breathing (SDB)) at night which can increase the risk of recurrent admissions and have important prognostic implications. SDB is however, treatable with the use of non invasive breathing support devices such as the adaptive servo ventilation (ASV) device. The aim of the study is to observe and investigate the potential role of ASV in the management of heart failure. Patients that agree to participate in this study will be requested to use an ASV ventilator device (called the AutoSet CS-A) to help their SDB for approximately 6 weeks. The device is approximately the size of a large shoe box, which can be placed at the side of the bed, with tubing and a mask. At night, the mask is placed over the nose and/or mouth and it blows positive air pressure as determined by the device itself as it constantly monitors the patients breathing throughout the night. During this study, the patients breathing patterns will be monitored non-invasively using the ApneaLink device. A non-contact device knows as a SleepMinder will sit on the patients bedside locker as another form of monitoring of their sleep patterns. Study staff will monitor the patient and give them frequent support, and they will also be asked questions regarding their experiences with this equipment and any symptoms they may have over this time. They will be followed up regarding this study at the same time as their follow-up requirements for their heart failure. This study will be conducted in total over 3 months.
Central Sleep Apnoea (CSA) affects up to half of patients with severe heart failure and is associated with a poor prognosis. CSA is manifest as episodes of deep breathing interspersed with very shallow or absent breathing and is largely due to an exaggerated response to rising carbon dioxide in the blood, which normally drives how hard we breathe. Cardiac Resynchronization therapy (CRT), in which a pacemaker is implanted to improve co-ordinated contraction of the heart, has been shown to reduce the severity of CSA in some patient groups. We aim to determine whether this improvement is due to normalization of the body's response to carbon dioxide in the blood. Our hypothesis is that CRT improves CSA by normalizing the brain's response to carbon dioxide.
