Case


Flight med calls your department. “We have a 41-year-old cardiac patient of yours with a catheter coming from his chest that has broken off. Blood was coming from it, so we clamped it off. He’s in respiratory distress and we’ll be landing in 5 minutes.”


Pertinent History


The patient is a 41-year-old male with a history of pulmonary hypertension who presents in respiratory distress. The broken line is used for a continuous infusion epoprostenol pump. The patient reports having non-bloody diarrhea for the last 3 days. He endorses nausea but has been tolerating fluids. He had mild SOB starting earlier today. However, just prior to calling EMS he fell due to lightheadedness while attempting to stand up quickly. His epoprostenol line caught on some furniture, causing it to tear. The broken off remainder is still in his chest. He did not lose consciousness or sustain any other injuries. Immediately following his line malfunction, he reports worsening shortness of breath, lightheadedness, and chest pressure.


Pertinent Physical Exam


Vitals: HR 125, RR 28, O2 sat 92% on 15 L/min, BP 102/74.


Except as noted below, the findings of a complete physical exam are within normal limits.



General:


The patient is in acute distress.



Pulmonary:


He is in respiratory distress and is speaking in 4–5-word sentences. Lungs are clear. Tachypneic with mild retractions.



Cardiovascular:


2/6 systolic murmur, JVD to angle of mandible, and a regular rhythm, Extremities with 1+ pitting edema.



Abdominal:


Exam is benign except for mildly increased bowel sounds.



Skin:


Pale, cool, and diaphoretic.



PMH


History of pulmonary hypertension and right heart failure. No other significant medical history. No surgical history.



SH


Patient does not drink alcohol, use illicit drugs, or smoke. Patient worked as a school teacher prior to developing pulmonary hypertension. He is currently on disability.

ECG – right axis deviation, tall P waves in inferior leads, prominent R wave in V1


Chest X-ray – mild cardiomegaly consistent with previous imaging, no evidence of pulmonary edema


POCUS – RV dilation and poor systolic function (Fig. 53.1), septal bowing into left ventricle, enlarged IVC with minimal respiratory variation
