Nebulizing inhalation combined with non-invasive ventilation therapy in COPD patients with respiratory failure and nursing．
To explore the application and nursing of oxygen-driven inhalation joint with non-invasive ventilation therapy in COPD patients with respiratory failure．
39 cases diagnosed COPD with respiratory failure during January 2011 to December 2012 in our department were randomly divided into two groups: the experimental group( 21 cases) and control group( 18cases). The experimental group using non-invasive ventilation combined oxygen-driven inhalation otherwise the control group using conventional inhalation therapy ( off-hook inhalation). Compare the improving of hypoxia，carbon dioxide retention, dyspnea, difficulty in expectoration, dry mouth and sore throat caused by noninvasive ventilation, and improving of lung function．
Lung function and blood gas analysis results were all improved in Two groups after treatment．In addition to 1 cases in observation group was send to ICU due to exacerbation, other cases were successfully weaned from non-invasive ventilator．
The length of stay and ventilation time in experimental group were significantly lower than the control group. The ratio of sore throat，dry mouth and difficulty in expectoration in experimental group was statistically significant lower than the control group，P＜0. 05．
Oxygen-driven inhalation therapy can improve the therapeutic effect and quality of life in COPD patients with respiratory failure using non-invasive ventilation during hospitalization and worthy of clinical application．
"Wishing all our valued partners, clients, and colleagues a Merry Christmas and a joyful holiday season from the VPLUS team! May the new year bring success, growth, and continued collaboration."

The lung’s delicate surfactant layer is of critical importance to the organ’s overall physiology and innate immune function. Both alveolar type II cells and alveolar macrophages are the principal subsets that maintain and catabolize surfactant at the liquid-air interface. Our study reveals that ENDS exposure disrupts both the lipid and protein components of pulmonary surfactant, […]

Neurodegenerative diseases leading to Parkinson's disease (PD) and Alzheimer's disease (AD) have become a major global health burden. Current treatments are mainly aimed at controlling symptoms, and there are no effective treatments in clinical practice to prevent neurodegeneration or induce neuronal repair. Therefore, the need for new research on these two diseases is urgent. The […]

Sativex® (nabiximols) is an oromucosal cannabinoid drug that contains 2.7 mg THC and 2.5 mg CBD per spray. It has been approved by regulators in 29 countries for the treatment of spasticity in multiple sclerosis. The medical application of cannabis began very early. From the mid-19th century to the 20th century, it was used by […]

Ultrasonic atomization uses ultrasonic directional pressure to make the liquid surface bulge, and cavitation occurs around the bulging liquid surface, causing the liquid to be atomized into small molecular mist. The oscillation frequency of the ultrasonic atomizer is 1.7MHz or 2.4MHz, which exceeds the human hearing range. The electronic oscillation is harmless to humans and […]
