Loop gain response to increased cerebral blood flow at high altitude

ConclusionPharmacological elevation in CBF significantly reduced LG and severity of CSA. We speculate the effect was on HCVR “controller gain,” rather than “plant gain,” because PaCO2 andVE were unchanged. An effect via reduced circulation time is unlikely, as the respiratory-cycle length did not change.
