	or more above the right atrium. The incidence of VAE in the sitting position is approximately 40 - 45%.
	Air entrainment may also occur in the lateral, supine or prone positions, but is much less likely.
	The primary pathophysiologic event in VAE is intense pulmonary vasoconstriction resulting in V/Q
	mismatch, pulmonary edema and reduced cardiac output.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.ccanesthesiareview.com/QOD/answers/ans32.asp?ans=X"><P class="RegularText">pg. 773
