Title was changed:
ProgresssiveProgressive iatrogenic pneumothorax from incorrectly connected Heimlich valve
Body was changed:

On physical exam hyperresonance noted onhyper-resonance of the left lung fieldsfield was noted when compared to the right, with no lung sounds auscultated on the left side when compared to the right side.  

PatientsThe patient's pigtail catheter was also examined also at this time with; the Heimlich valve was noted to be placed backwardsin reverse with the pigtail closed off to prevent aircatheter obstructed, therefore preventing gas from escaping.  

The Heimlich valve connectedwas re-connected to atriumthe chest drainage set with 20 cm to wall suction with notable airgas bubbles present after connection.

Presentation was changed:
Follow up chest xX-ray to assess pneumothorax.

Updates to Quizquestion Attributes

Question was changed:
Which end of the Heimlich valve is closer toshould be orientated towards the patient - blue or clear end?

Updates to Quizquestion Attributes

Answer was changed:
In this case, the cause was notcannot be seen on the xX-ray and. Examination of the chest tube set-up demonstrated that the Heimlich valve was noted to behad been connected the wrong way.
