Do all cpaps require those funky nasal pillows? They make my nostrils so sore that I need a day to heal.

We understand that the key variable is not airway pressure per se, as elegantly demonstrated by Bouhuys in studies of musicians playing musical instruments (Figure 8) (24), but was due to overdistension of the lung as demonstrated by Dreyfuss and Saumon, who suggested the term volutrauma to highlight that it was not the absolute airway pressures per se that were important, but the overdistension (25)...snip Snip...In 1997, we identified a mechanism of injury that we called biotrauma (i.e., the biological consequences associated with mechanical ventilation) (26, 27). We showed that injurious forms of ventilation (i.e., those that promote atelectrauma or overdistension) could lead to release of mediators in the lung. Coupled with the increased permeability due to the underlying disease being treated (e.g., ARDS) or the increased permeability caused by overdistension, mechanical ventilation could lead to translocation of mediators, bacteria, or endotoxin into the systemic circulation (27, 28). This in turn could cause end-organ dysfunction distal to the lung (e.g., kidneys) and lead to multiorgan failure (Figure 9) (29). This mechanism could explain the fact that most patients with ARDS who die do so not because of hypoxemia but because of multiorgan failure...snip http://www.atsjournals.org/doi/full/10.1164/rccm.201503-0421PP ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ > From: Kaleb C.
