Role of Lung Ultrasound and Pulsed-wave Doppler in Lung Consolidations in Mechanically Ventilated Patients

Pneumonia | Atelectasis

In infectious lung consolidations, the inhibition of hypoxic pulmonary vasoconstriction (HPV) results in a higher regional acceleration time (RAcT) compared to the RAcT measured in atelectatic consolidations.
