The postnatal developments of the rat and hamster were compared after the animals were raised from birth for 21 days either in normoxia (control animals) or chronic hypoxia (PO2 of 80-90 Torr). Compared with control rats, hypoxic rats had a reduction in body mass. Hypoxic rats had lowered O2 consumption (VO2) and increased (67%) ventilation (VE), whereas hypoxic hamsters maintained the same metabolic rate as control hamsters but increased VE by 100%. As a result, when raised in hypoxia both… CONTINUE READING
