far right of the bell curve of risk of desaturation
- Need a reasonable FRC
- full oxygenation of that FRC
- That volume connected to the alveolar vessels -to be transmitted to the bloodstream
Tanoubi et al. estimation of safe apnea time formula

Why doesn't apox work
it is shunt fraction and its syngergistic partner low SvO2

Need a lot more PEEP when transitioning from NPV to PPV

PEEP is maint. in addition to recruitment

Pendelluft Phenomena movement of gas from recruited lung to non-recruited causing lung injury

he also postulates an abrupt increase in r sided heart pressures made even worse by bagging

Does 100% precipitate absorption atelectasis--no! put in the article from crashing patient

#### Mosier et al. WestJem  2015;16(7):1109
added R sided failure to the HOP killers
nebulized milrinone
