Screen shots of serious game.
<p>A) Each case included a 2-D rendering of the patient, a chief complaint, vital signs, a history, and a written description of the physical exam. Physicians had 42 minutes (a simulated 8 hour shift) to complete the ten cases. A clock at the top right of the screen helped track the passage of time. B) Physicians could manage patients by selecting from a pre-specified list of 250 medications, studies, and procedures. C) We included audio-visual distractors, including nursing requests for help with disruptive patients to increase the verisimilitude of the experience.</p

Arterial blood gas measurements in mice bled to and maintained at a MAP of 20 mm Hg for 30 minutes with and without inhaled CO (250 ppm).
<p>*P<0.05 compared to sham mice.</p><p><sup>§</sup>P<0.05 compared to shock mice.</p><p>Sham mice underwent anesthesia and surgical manipulation without hemorrhage. Mice were bled to a pressure of 20 mm Hg over 15 minutes. CO therapy was started once a pressure of 20 mm Hg was reached.</p
CO protects against organ injury and inflammation in a dose dependent fashion in murine model of hemorrhagic shock and resuscitation.
<p>Lung myeloperoxidase activity (MPO; <b>A.</b>) and serum ALT (<b>B.</b>) at 4 hours after resuscitation in mice demonstrates lung and liver injury, respectively. CO limits this injury in a dose-dependent fashion when treated for 30 minutes (25–500 ppm) starting 90 minutes into hypotension. C. Serum TNF-alpha and IL-6 levels were also increased by hemorrhagic shock and resuscitation at a 4 hour time point, and CO therapy limited these markers of inflammation in a dose dependent fashion. Results are mean±SEM for 8 mice per group. *P<0.05 compared to sham and #P<0.05 compared to shock. ANOVA was utilized for above comparisons.</p
CO therapy protects against mortality in a model of murine hemorrhagic shock and resuscitation.
<p>A severe hemorrhagic shock and resuscitation model resulted in 80% mortality by 36 hours. CO therapy (250 ppm) limited mortality to 20% (P<0.05). Kaplan-Meier method was used to compare survival.</p
CO decreases oxygen consumption and limits the development of cellular hypoxia in hepatocytes in vitro.
<p>A. Oxygen consumption rates of primary murine hepatocytes were demonstrated <i>in vitro</i> in normoxic cells or in hepatocytes immediately following 30 minutes of hypoxia. CO treatment (250ppm) occurred during this normoxic or hypoxic periods. Hypoxia decreased oxygen consumption rates (*P<0.01 compared to normoxic cells) and this was further decreased by CO therapy (#P<0.05 compared to hypoxia alone). Results of four independent experiments, with each condition performed in triplicate. <b>B, C.</b> Representative immunocytochemistry and quantitative mean fluorescence of hypoxyprobe staining in hepatocytes under normoxic, normoxic+CO, hypoxic, or hypoxic +CO conditions for 30 minutes. Increased green staining represents increased cellular hypoxia. ANOVA was utilized for above comparisons.</p
