The proposed research study is a cross-sectional study enrolling young children with sickle cell disease between 5 and 12 years of age. They will be screened as outpatients for consent to perform pulmonary function testing (PFT) and echocardiography. In addition, the degree of bronchodilator response will be assessed at each session. To estimate presence of pulmonary hypertension, echocardiography will be performed at the time of PFT measures.
