Fig. 7From: Hypercapnia induces IL-1β overproduction via activation of NLRP3 inflammasome: implication in cognitive impairment in hypoxemic adult ratsGraphs a to i illustrate the PaCO2, pH, and PO2 of supernatants (n = 4). 15% CO2 treatment significantly increases the PaCO2, with pH at 7.20–7.25, and 0.2% O2 treatment maintains the PO2 levels at around 60 mmHg, while there are no interaction effects between 15% CO2 treatment and 0.2% O2 treatment (P > 0.05)Back to article page
