Respiratory dysfunction following cardiac surgery is well documented and due in part to the location of the incision and nature of the surgery. Post-operative pulmonary complications (PPCs) remain a significant problem following cardiac surgery, sometimes causing prolonged length of stay in hospital as well as increased morbidity and mortality; with the greater risk to older adults and individuals with obstructive lung disease. Positive expiratory pressure (PEP) therapy is thought to increase lung volumes and facilitate secretion clearance. The purpose of this study is to investigate whether the addition of oscillating PEP therapy to standard postoperative treatment is more effective in decreasing the incidence of PPCs and increasing functional capacity at time of discharge in 'high risk' patients undergoing elective cardiac surgery.
The trial shall assess the accuracy of the Oxitone® 1000 in measuring oxygen saturation, by comparing its measurement to reference devices: non-invasive SpO2 and pulse-rate values determined by a pulse oximeter. A total of approximately 40 subjects: 20 healthy and 20 COPD (chronic obstructive pulmonary disease ) patients will be enrolled. These subjects will be enrolled at the medical center pulmonary department and will be recruited from the clinic patient base. The subjects will be represented by male and female adults who optimally cover a range of ethnic backgrounds (skin pigmentation). All testing will be performed in singleton and in a blinded fashion. This study will be conducted with the approval of the medical center ethics committee. This is a comparison open study with no subject follow-up.
This study will investigate the prevalence of chronic obstructive pulmonary disease (COPD) in patients who are newly diagnosed with lung cancer and compare it to the prevalence of COPD in controls recruited from a smoking cessation clinic.
To evaluate the pulmonary gas exchange response to a therapeutic high dose of inhaled indacaterol (300 mcg) in 20 outpatients with stable symptomatic COPD B and D GOLD 2011 groups. Measurements on a single day before and after 60 and 120 minutes of indacaterol will include arterial PO2, PaCO2 and pH. AaPO2; SaO2 (by pulse oximetry) and oxygen and carbon dioxide in exhaled breath, systemic arterial pressure and heart rate will also be measured/calculated. Cardiac output will be directly measured by bio-impedance.
To test the hypothesis that nebulized Pulmicort Respules could reduce post operation pulmonary complication incidence in primary lung cancer patients with COPD. Compare post-operation pulmonary complication incidence in two treatment arms among primary lung cancer patients with COPD required single lobectomy from 3days before operation to 7 days after operation.
Pulmonary arteriovenous malformations (PAVMs) are a rare vascular condition affecting the lungs. PAVMs lead to low blood oxygen levels, yet are very well tolerated by patients. This study will examine the exercise capacity of PAVM patients using formal cardiopulmonary exercise tests performed on a stationary bicycle, and whether this is affected by the presence of concurrent airflow obstruction, such as due to asthma.
Chronic Obstructive Pulmonary Disease (COPD) is a frequent disease, with increasing prevalence. Pulmonary rehabilitation through general exercise training (GET) is a corner stone of COPD care. Inspiratory muscle training (IMT) as a stand-alone therapy decreases dyspnea and improves exercise capacity. Whether IMT combined with GET adds a supplementary benefit in the rehabilitation of COPD patients is however uncertain.
The study will investigate the effects of different training types ,including combined inspiratory with expiratory pressure threshold training,inspiratory pressure threshold training on patients with chronic obstructive airway disease and investigate whether expiratory pressure threshold training associated with inspiratory pressure threshold training would be better than inspiratory pressure threshold training alone, with regard to exercise capacity, respiratory muscle strength and endurance.
Chronic obstructive pulmonary disease(COPD) is a common disease among people. Acute exacerbation of chronic obstructive pulmonary disease(AECOPD) is the acute and aggravating phase of COPD which may lead to respiratory failure. Mechanical ventilation is a very important therapy for those patients,but traditional ventilation modes have some defects, so investigators need to find new modes to solve these problems. In this study, the investigators compare neurally adjusted ventilatory assist (NAVA) and PSV to observe the effects on AECOPD patients' air distribution and dead space to determine if NAVA is a more appropriate ventilation mode for AECOPD patients.
