An EtCO2 reading of 50 mmHg indicates which respiratory state?

Explanation:
End-tidal CO2 reflects how well the animal is ventilating relative to CO2 production. Normal EtCO2 is about 35–45 mmHg. A reading of 50 mmHg means hypercapnia, indicating hypoventilation or another cause of CO2 retention (eg, increased production, airway obstruction, or reduced expiratory flow). In practice, you’d check anesthesia ventilation settings and airway patency to bring EtCO2 back toward normal. Hypocapnic would be too low, normocapnic would be normal, and hypoxic refers to low oxygen, not CO2.
