NCT01361451
There are 24,000 admissions each year to Intensive Care Units (ICU) in the United Kingdom due to pneumonia, asthma and a common condition called chronic obstructive pulmonary disease (COPD), with rates of death of 10%, 40% and 50%, respectively. These conditions account for 10% of all ICU admissions. It is therefore important to find out if it would be possible to detect deteriorations in patients with breathing problems early, in order to increase appropriately their level of care. Clinical early warning scores (EWS) are used in many hospitals to detect patients whose medical condition is getting worse, and who are likely to need admission to intensive care or high dependency care units. EWS are usually calculated from several measurements taken from the patient, such as blood pressure, temperature and heart rate. However, they are often inaccurate as they need to be calculated manually by nursing staff from a number of measurements taken from a variety of different devices. Furthermore, even when accurately calculated, it is not clear how helpful EWS are in predicting whether or not patients will deteriorate. Neural respiratory drive (NRD) is an objective indicator of breathlessness, and can be derived from the amount of electrical activity occurring in certain muscles used in breathing. The Myotrace system measures this electrical activity, as well as measurements such as rate of breathing and heart rate. It then analyses these measurements together to help identify patients at risk of deterioration. This study will use Myotrace to monitor patients with severe breathing difficulties due to an acute worsening of chronic obstructive pulmonary disease, for early identification of failure to respond to medical treatment. Patients will be recruited at St. Thomas' Hospital. This research is funded by the Guy's and St. Thomas' Charity.

Obstructive sleep apnea (OSA) is a chronic, progressive and disabling disease and can affect functional capacity due to the weakness of the respiratory muscles. Therefore, the objective of this study is to evaluate the effect of inspiratory muscle training on functional capacity in patients with OSA. A pilot study will be conducted to calculate the sample. Individuals of both genders, diagnosed with obstructive sleep apnea moderate or severe (measured by polysomnography) will be invited and the data collected in the Sleep Laboratory of the Pronto-Socorro Cardiológico de Pernambuco (PROCAPE), located in Recife- PE- BRAZIL. The study deals with a test-clinical randomized double-blind.The intervention groups held inspiratory muscle training (IMT) and the load is equivalent to 40% of maximal inspiratory pressure (MIP). The evaluations will be performed once a week during twelve weeks. Control groups will be submitted to a simulated training with load less than 10% of MIP (insufficient charge to train the muscles), during the same period as the intervention group. The guidelines for the training and weekly evaluations will be performed by the responsible for the researcher physiotherapist in Cardiopulmonary Physical Therapy Laboratory (LACAP- UFPE). After the training period, the groups will be reassessed by the evaluation tests of functional capacity (ADL- Glittre Test and Ergospirometry), inspiratory muscle strength (manometer) and lung function (spirometry) and then compared. Expected results: The interventional groups will improve their functional capacity.
