I will keep medical posts to a minimum, but this one was worthy of relating.
One of our responsibilities in the hospital is to read X-rays ordered by the MAs. This one caused us to run out of the office to try and locate the patient.
We couldn't find the patient. He was out getting lunch! So he couldn't be that sick. After lunch he turned up to find out the results of his X-ray and was shuttled into the emergency hallway. Though quite short of breath, his blood pressure was not yet low, so it hadn't progressed far enough to be immediately life threatening. We placed a chest tube (the very tip of which can be seen on the edge of the X-ray below) which permitted the left side to decompress. Over three days he improved and we removed the tube. You can see the diaphragm is less flattened and the heart has shifted back its accustomed position. He went home very happy.
