Chemoreceptors respond to which condition and what is the fetal heart rate effect?

Explanation:
Chemoreceptors monitor chemical changes in the fetus, especially CO2 and pH. When CO2 levels rise, these receptors initiate a reflex that tends to slow the fetal heart rate. This bradycardic response reflects the autonomic adjustment to hypercapnia/acidosis and helps match oxygen delivery with metabolic needs during distress. So the best pairing is increased CO2 levels with decreased fetal heart rate.
