An increase in peak inspiratory pressure (PIP) over time in a mechanically ventilated patient indicates a decrease in lung compliance. This means the lungs are becoming stiffer and less able to expand, which can be caused by conditions such as pulmonary edema, ARDS, or pneumothorax. It is important to address the underlying cause of decreased lung compliance to prevent further respiratory complications. References: = CCRN Exam Handbook, AACN Adult CCRN Certification Review Course
