ABSTRACT:
Inflatable cuff-type catheters, e.g., endotracheal and tracheotomy tubes, with cuff pressure indicators are provided. One indicator means comprises an expandable chamber with an open-ended spring about the mid-section of the chamber. As the chamber expands, the spring also expands to indicate the gas pressure in the cuff.
