Clinical CT for November 2015

A 47 year old male with no past medical history presents to the ED with shortness of breath and dizziness first noted while he was working and lifting heavy objects. He is a truck driver and recently returned from a long trip on the road. His symptoms started 12 hours ago. Denies chest pain, no syncope, no fevers, chills, or cough, no hemoptysis. VS on triage: BP 140/90, HR: 104, RR: 19, SAT: 98% on RA but desats down to 88% when ambulating, T: 98. Rest of the exam is unremarkable and the patient does not appear toxic or in any severe distress. ECG demonstrates sinus tachycardia with right bundle branch pattern (no prior for comparison), and bedside transthoracic echocardium demonstrates good LV systolic function but there is evidence of right heart strain with IV septal bowing into the LV (“D sign”) on short axis view, with no pericardial effusion. Labs are only notable for troponin level of 0.2. A CT pulmonary artery is performed…this is looking like just another day at the County.20151116_151834.jpg

Clinical Radiograph for October 2015

A 50 year old woman with a history of HIV/AIDs comes into your emergency department with acute shortness of breath. The patient is breathing shallowly at 40 breaths/minute and cannot give a history. As the nurses are hooking her up to the monitor you find a small chest tube with a Heimlich valve in place.

Vitals: HR 120   BP 90/40   O2 sat 91% on non-rebreather

You listen to her anterior lungs and here breath sounds bilaterally. While you’re setting up to intubate, the xray technician rolls in you get the XR shown here:

Loculated ptx

You look back through her chart and see that she was discharged last week after a long hospital stay for a MAC infection which was complicated by ARDS, intubation, pneumothorax and subsequent chest tube placement.

QUESTIONS:

  1. What is the diagnosis?
  2. How is this different than a typical pneumothorax?
  3. How do you treat this?
  4. How does a Heimlich valve work?
  5. How do you troubleshoot a clogged Heimlich valve?
