A 26-year-old male presents to the ED after a stab wound to the left chest.  The patient has stable vital signs and has diminished breath sounds on the left but the patient is splinting due to pain.  You and your resident perform a FAST exam and see no evidence of a pericardial effusion. During performance of a thoracic ultrasound for the detection of a pneumothorax, your resident comments that he sees a lung point.  What is your interpretation?
