Figure 10. Experimental hypoxia chamber. (A) The hypoxia chamber for animal experiments includes an external operation panel and an internal cabin; ① vacuum pump; ② fans; ③ monitor device; ④ monitor screen; ⑤ cooling hole. (B) Parameter settings. The red box indicates cabin’s air flow setup: cold air enters, air is discharged, and air is exchanged. (C) Animal modeling time and equipment running process. (D) Time-height curve, comprising a rising stage (t0), cultivated room running time (t1), and a constant speed drop phase (t2).
