Tension PTX

You've done a bowel case for a perfed DU in an otherwise young healthy guy who took too much naproxen... At the end of the case, you put in a triple lumen with ultrasound, but still manage to get a little hole in the pleura... Patient extubated and in PACU, develops shortness of breath... can anyone walk me through the physiology of how this patient could develop a tension PTX if he's spontaneously breathing and not positive pressure ventilated... ?
