Lungs Perfusion and Ventilation of Lung Parts

as i know the dependent part of the lung get the greatest perfusion and ventilation , then why in massive haemoptysis we keep the patient lying on the side of the bleeding lung , it will get more perfusion which means more bleeding and also more ventilation which on other side will decrease ventilation and perfusion to the normal lung??????

The main reason for placing the haemorrhaging side laying down is to protect the non bleeding side. You need to stop the blood from leaking into the non bleeding side which would only further complicate things
