The current frequency of noninvasive (NIV) and invasive mechanical ventilation use in asthma exacerbations (AEs) and the relationship to outcomes are unknown. ⋯ There was a substantial increase in the use of mechanical ventilation, accompanied by a shift from invasive mechanical ventilation to NIV. Although we could not determine the clinical reasons for this increase, hospital stay and mortality were unchanged. A randomized trial is needed to determine whether NIV can improve outcomes in AEs before widespread adoption makes it impossible to conduct such a trial.

The effect of expiratory rib cage compression before endotracheal suctioning on the vital signs in patients under mechanical ventilation.
In patients undergoing mechanical ventilation, mucus production and secretion is high as a result of the endotracheal tube. Because endotracheal suction in these patients is essential, chest physiotherapy techniques such as expiratory rib cage compression before endotracheal suctioning can be used as a means to facilitate mobilizing and removing airway secretion and improving alveolar ventilation. As one of the complications of mechanical ventilation and endotracheal suctioning is decrease of cardiac output, this study was carried out to determine the effect of expiratory rib cage compression before endotracheal suctioning on the vital signs in patients under mechanical ventilation. ⋯ Findings showed that expiratory rib cage compression before endotracheal suctioning improves the vital signs to normal range in patients under mechanical ventilation. More studies are suggested on performing expiratory rib cage compression before endotracheal suctioning in patients undergoing mechanical ventilation.

There is controversy about the effects of high plasma bicarbonate concentration ([HCO3(-)]) and the CO2 response test. We analyzed the relationship between [HCO3(-)] and the variation in hydrogen ion concentration (pH) for a given change in PaCO2, and its effects upon CO2 response. ⋯ There is an inverse linear relationship between [HCO3(-)] and the variation of pH for a given change in PaCO2 and the CO2 response.

Multicenter StudyTargeting occult heart failure in intensive care unit patients with acute chronic obstructive pulmonary disease exacerbation: Effect on outcome and quality of life.
To estimate the prevalence of previously undiagnosed heart failure in mechanically ventilated patients with severe exacerbation of chronic obstructive pulmonary disease (COPD) and to evaluate the impact of specific heart failure treatment on patients' outcome. ⋯ In mechanically ventilated patients with severe exacerbation of COPD, unrecognized left or right ventricular failure is common. Among patients with isolated left ventricular failure, the early detection and appropriate treatment improves long-term quality of life and may decrease the short- and 6-month morbidity and mortality.
