Answer

Answer

HPS is detected most readily by echocardiographic visualization of late-appearing bubbles in the left atrium following the injection of agitated saline. Patients can receive a diagnosis of HPS when their PaO2 is less than 70 mm Hg. Some cases of HPS may be corrected by liver transplantation. In fact, a patient's course to liver transplantation may be expedited when his or her PaO2 is less than 60 mm Hg.
