whats the TGA? that sucks, bubble pep is great. easy to do with a milkbottle and a bit of surgical tubing - never had any problems with it in the hospital before.

Anyway I checked Pryor and Prassad and can only find 1 referance for 10-20 cm H20 - Positive expiratory pressure (PEP) mask. In: Pryor JA (ed) Respiratory care. Churchill Livingstone, Edinburgh, pp 51-63.

Not sure how that works - appears to have been published in pryor's previous book?
