Exclusion criteria of acutely ill patients
Instead, we excluded patients belonging to group 1 of our study sample -acutely ill children - but who also had acute upper or lower
respiratory tract infections (attested by molecular and cultural
microbiological examinations of the airways). In addition, we excluded
patients with histories or symptoms and signs of other acute and chronic
respiratory diseases (aspiration pneumonia, pneumothorax, pulmonary
embolism, interstitial fibrosis, pneumonectomy outcomes, respiratory
tract abnormalities), with a history of immunodeficiency, paralysis
brain, neuromuscular diseases and malignant tumors because LUS can
provide only limited findings to identify a pattern of lung imbibition
from non-primarily cardiac causes in these patients.
