Acute chest syndrome

(ACS) a common complication in patients with sickle cell disease (SCD), responsible for considerable morbidity and mortality in these patients

Description
The ACS can be defined as:
 * 1) a new or worsening infiltrate on chest x-ray
 * 2) one or more new or worsening symptoms: fever, cough, chest pain, sputum production, dyspnea, or hypoxia. ACS may need urgent transfusion or excange transfusion and treatment of the underlying condition (infection, vasoocclusive crisis). Incentive spirometry is a good weapon for its prevention.
