Aspergillus colonization in patients with chronic obstructive pulmonary disease
Background and Purpose: Chronic obstructive pulmonary disease (COPD) has been recognized as a risk factor for invasive aspergillosis. Airway colonization by Aspergillus species is a common feature of chronic pulmonary diseases. Nowadays, the incidence of COPD has increased in critically ill patients. The aim of the present study was to isolate and identify Aspergillus colonies in the respirator...
متن کاملNeural respiratory drive and neuromuscular coupling in patients with chronic obstructive pulmonary disease (COPD).
In 15 spontaneously breathing patients with chronic obstructive pulmonary disease (COPD) divided into two groups, one with normocapnia (A) and one with chronic hypercapnia (B), we evaluated the maximal voluntary inspiratory muscle strength (MIP), the pattern of breathing, the mouth occlusion pressure (Po.1), the neural respiratory drive (NRD), assessed by surface electromyographic (EMG) activit...
متن کاملRespiratory disorders during sleep in chronic obstructive pulmonary disease
Patients with COPD may show slow, progressive deteriorations in arterial blood gases during the night, particularly during rapid eye movement (REM) sleep. This is mainly due to hypoventilation, while a deterioration of ventilation/perfusion mismatch plays a minor role. The severity of gas exchanges alterations is proportional to the degree of impairment of diurnal pulmonary function tests, part...
متن کاملTransdiaphragmatic pressure and neural respiratory drive measured during inspiratory muscle training in stable patients with chronic obstructive pulmonary disease
PURPOSE Inspiratory muscle training (IMT) is a rehabilitation therapy for stable patients with COPD. However, its therapeutic effect remains undefined due to the unclear nature of diaphragmatic mobilization during IMT. Diaphragmatic mobilization, represented by transdiaphragmatic pressure (Pdi), and neural respiratory drive, expressed as the corrected root mean square (RMS) of the diaphragmatic...
متن کاملNeural respiratory drive during apnoeic events in obstructive sleep apnoea.
For a given neural drive, oesophageal pressure during apnoeic episodes may differ from that during airflow, since inspiratory airflow and increased lung volume both reduce pressure generation. It was, therefore, hypothesised that diaphragm electromyography (EMG) may provide additional data to oesophageal pressure when used for the assessment of neural drive in patients with obstructive sleep ap...
