Bilateral carotid body resection in man enhances XXXX .

@entity2944 @entity871 @entity591 @entity519 @entity299 @entity4095
In three groups of subjects we studied @entity299 ( @entity299 ) and ventilatory responses to progressive @entity519 , steady-state @entity2944 with and without @entity519 , and hyperoxic and @entity519 breathholding (BH). Groups were six subjects about 25 years after bilateral carotid body resection (BR), eight subjects of an equally long period after unilateral resection (UR), and three control subjects similar to the study groups in age and pulmonary function (C). During progressive @entity519 , @entity299 increased more in BR than in UR and C subjects. Ventilatory response was lowest in BR subjects (as expected). Steady-state @entity519 @entity2944 (end-tidal @entity4095 , 60 Torr) depressed @entity299 significantly more in C than in BR and UR subjects. Again, ventilatory response was lower in BR than in C subjects. @entity299 progressively increased during BH initiated in @entity871 (end-tidal @entity4095 , 200 Torr) and @entity519 (end-tidal @entity4095 , 70 Torr). In the BR group, the @entity299 increment during @entity519 was significantly larger than that during @entity871 . No such difference was apparent in UR and C groups. Thus, @entity519 with or without @entity2944 tends to accelerate @entity299 in BR subjects whereas either less @entity591 or slowing is seen in UR and C subjects.
