phrenic pressure test
phren·ic pres·sure test
pressure is applied on the phrenic nerve on each side, above the clavicles where the nerve passes over the scalenus anticus muscle; if pain is perceived and the patient inclines the head to the painful side, the problem is in the pleural space; if the head does not incline to one side, the problem is in the abdominal cavity.
