Typical respiratory recordings under normoxia [inspired O2 fraction (FiO2) = 21%] from three different pups at postnatal day 4 (P4), P7, and P21 after a single injection of either vehicle (saline; A), suramin (B), or A-317491 (C). These examples were obtained during the last 5 min of recording during normoxia. Note that these are flow traces; tidal volume is calculated from the integrated signal. Inspirations correspond to downward deviations below 0.
