TazziRN and RN-Cardiac. Thank you both for responding. It is important to know that the volume is 10mL, I actually did not know that. However I did stumble upon the question about pressure in one of the tests I was taking for an agency a month ago, the options were offered in mmHg and I did find minimal info online but I do not trust sources I do not know, anyone can put up a web page claiming anything they like.
While you do put 10 mls of air when initially inflating the cuff of an ett,
you have to periodically check the pressure placed on the vocal cords by the cuff by using a manometer attached to the pilot balloon. If the pressure is too high, you risk damage to the cords, too low and a pt doesn't get their tidal volumes. We check the pressure every 8 hours minimum.

Hello all. I could not find in neither my med-surg nor my fundamentals book the maximum pressure of a cuff on an endotracheal or tracheostomy tube. Also I saw some readings on the net in mmHg and mmH2o and was wondering how they compare. Please let me know what the appropriate pressure is and if possible please cite your sources.
Thanks a bunch.
