Meanings
- not comparablePertaining to the regulation of respiratory rate.
The inhibitory neurons that switch off the inspiratory ramp arise from the pneumotaxic center and pulmonary stretch receptors, which are discussed in the next section.
2013, Will Beachey, Respiratory Care Anatomy and Physiology, →ISBN2 more examples
The inspiratory-off switch (IOS) system consists of discharges arising from firstly, the pulmonary stretch receptors through the Breuer-Hering reflex and secondly the pneumotaxic pattern generator.
2013, Robert Fitzgerald, The Regulation of Respiration During Sleep and Anesthesia, →ISBN, page 6Traditionally, the pontine pneumotaxic mechanism has been thought to contribute a tonic descending input that lowers the IOS threshold in medullary respiratory central pattern generator (rCPG) circuits, but otherwise does not constitute part of the rCPG.

Origin
Analysed as pneumo- + -taxic, and the latter is from τάξις (táxis, “arrangement”)
