Figure 2. The effects of three different levels of oxygenation upon a chemoreceptor unit.

Figure 2

The Pa,CO2/pHa values for A, B and C are 35 mmHg/7.3, 34 mmHg/7.3 and 43 mmHg/7.23, respectively. This unit differs from the one shown in Fig. 1. These records were made after the rat had been at the appropriate inspired oxygen fraction for at least 5 min. Arterial blood was sampled subsequently, during the 5th minute of a steady-state level of discharge.
