Diagnosis of mediastinal/hilar lymph nodes and tumours is often challenging for patients with previously treated thoracic malignancy, especially when they have a history of thoracotomy. Endobronchial ultrasound with transbronchial needle aspiration (EBUS-TBNA) has been proposed as a safe, less-invasive modality for such patients. We retrospectively evaluated the role of EBUS-TBNA ...

Morbid obesity adversely affects respiratory physiology, leading to reduced lung volumes, decreased lung compliance, ventilation perfusion mismatch, sleep-disordered breathing and the impairment of ventilatory control and neurohormonal and neuromodulators of breathing. Therefore, morbidly obese subjects are at increased risk of various pulmonary complications that can present either acutely or chronically. ...

Patients with heart failure (HF) and Cheyne-Stokes respiration or periodic breathing (PB) often demonstrate improved cardiac function when treatment with continuous positive airway pressure (CPAP) resolves PB. Unfortunately, CPAP is successful in only 50% of patients, and no known factor predicts responders to treatment. Because PB manifests from a hypersensitive ...

For patients with neuromuscular disease, air stacking, which inflates the lungs to deep volumes, is important for many reasons. However, neuromuscular patients with severe glottic dysfunction or indwelling tracheostomy tubes cannot air stack effectively. For these patients, we developed a device that permits deep lung insufflations substituting for glottic function. ...
