Anna A. Lerant, Robert L. Hester, Thomas G. Coleman, William J. Phillips, Jeffrey D. Orledge, W. Bosseau Murray
2015 International Journal of Medical Sciences  
We programmed HumMod, to A.) compare varying times (0-7 minutes) of pre-oxygenation on oxygen saturation (SpO2) during subsequent apnoea; B.) simulate hyperventilation after apnoea.  ...  We suggest the use of HumMod, a computer-based human physiology simulator, to demonstrate beneficial physiological responses to pre-oxygenation and the futility of excessive minute ventilation after intubation  ...  At 5 minutes, to simulate apnoea, the simulated patient's respiratory rate was set to zero. The simulation was stopped when the SpO2 decreased to 80% to simulate a desaturation episode.  ...
