[The analysis of 252 episodes of recruitment maneuver during mechanical ventilation in surgery intensive care unit].
To analyze the clinical effects of recruitment maneuver and the impacts on blood pressure and oxygen saturation in patients with mechanical ventilation. ⋯ Recruitment maneuver could effectively improve oxygenation while the value of PEEP used should be individualized according to clinical condition.

Randomized Controlled Trial[Establishment of artificial airway with a thermal-softened nasotracheal tube guided by fiberoptic bronchoscope].
To assess superiority and safety of nasotracheal intubation with a thermal-softened tube guided by fiberoptic bronchoscope to establish an artificial airway for the institution of mechanical ventilation. ⋯ The use of a thermal-softened nasotracheal tube to intubate guided by a fiberoptic bronchoscope to establish an artificial airway shortened preparation time before intubation. It is not necessary to use a vasoconstrictor for nasal mucosa before intubation, therefore cardiovascular effects due to the drugs can be avoided. It increases the willingness of conscious patients to accept the procedure and successful rate of the first intubation.

[The influence of different respiratory frequencies on hemodynamics in patients on artificial ventilation].
To discuss the influence of different mechanical respiratory frequencies on hemodynamics in patients on mechanical ventilator. ⋯ With an increase in the ratio of spontaneous breaths to control ventilation in patients on mechanical ventilator, cardiac preload is increased, so cardiac output is also increased.

[Efficacy and safety of non-invasive positive pressure ventilation in the care of dyspnea after cardiac surgery].
To study the efficacy and safety of non-invasive positive pressure ventilation (NPPV) in the care of dyspnea after cardiac surgery. ⋯ These results suggest that NPPV is an effective and safe means for improving dyspnea and tissue perfusion, decreasing arrhythmia and necessity for reintubation, shortening the length of stay in ICU and decreasing mortality in dyspneic patients after cardiac surgery.

Practice Guideline[Guideline for mechanical ventilation in patients with acute exacerbation of chronic obstructive pulmonary disease (2007)].
Chronic obstructive pulmonary disease (COPD) is one of the major causes of chronic morbidity and mortality throughout the world, while acute exacerbation of COPD (AECOPD) is one of the important causes for the patient to be hospitalized. As COPD is a disease state characterized by irreversible airflow limitation and dynamic pulmonary hyperinflation, the mechanical ventilation strategy for its AECOPD is different from other diseases. To improve the clinical result of mechanical ventilation for AECOPD, Chinese Society of Critical Care Medicine of Chinese Medical Association held a consensus conference to draft a guideline by categorizing all the information gathered from the literature into five grades from A to E, with A being the highest, according to a modified Delphi criteria. ⋯ Proper selection of ventilation mode, and careful adjustment of tidal volume, respiratory rate, inspiratory flow rate and positive end-expiratory pressure are important in oder to avoid dynamic pulmonary hyperinflation. 4. Sequential ventilation (early extubation following by NPPV) is recommended as a weaning strategy for intubated patients. 5. For those in whom exacerbation is due to pulmonary infection, NPPV should be initiated with pulmonary infection control (PIC) as the window to decrease the duration of invasive ventilation, the risk of ventilator associated pneumonia, and hospital mortality.
