Oxygen saturation in adults with acute asthma

[Severe acute asthma: its management in emergency visits and intensive care]

All patients with asthma are at risk of suffering an acute asthma attack over their lifetime, and these may finally be fatal. Hospitalizations and emergency department visits and intensive care account for a large proportion of the health-care cost burden of asthma. Thus, it is especially important to establish plans for prevention, education and therapeutic rationalization of primary care that establishes the disease and decreases its worsening. The severity of the exacerbations may vary from a mild to life threatening. The mortality is basically linked to inadequate assessment of the patient's severity. This leads to inadequate treatment in the emergency and delay in the patient's hospitalization. This review describes the epidemiology, costs, pathophysiology, mortality and management of adult acute asthma patients in the emergency department and intensive care, especially that related to non-invasive mechanical ventilation and conventional forms of mechanical respiratory care, with the current changes in its operational strategy.

Acute asthma in adults: a review

All patients with asthma are at risk of having exacerbations. Hospitalizations and emergency department (ED) visits account for a large proportion of the health-care cost burden of asthma, and avoidance or proper management of acute asthma (AA) episodes represent an area with the potential for large reductions in health-care costs. The severity of exacerbations may range from mild to life threatening, and mortality is most often associated with failure to appreciate the severity of the exacerbation, resulting in inadequate emergency treatment and delay in referring to hospital. This review describes the epidemiology, costs, pathophysiology, mortality, and management of adult AA in the ED and in the ICU.
