We examined in male Rhesus monkeys the effects on oxygen consumption (VO2), carbon dioxide production (VCO2), minute ventilation (VE), heart and respiratory rates, and functional residual capacity (FRC) of breathing normal saline (NS), salbutamol (albuterol), methacholine (MCh), sodium cromoglycate (SCG), epinephrine (adrenaline), and terbutaline in doses commonly prescribed to human infants and children. We studied 10 anesthetized and intubated monkeys with a mean age and weight of 6.0 yr and 9.1 kg, respectively. VO2 increased over control, by 46.5% after salbutamol (p less than 0.0005), 25% after methacholine (p less than 0.001), 13.2% after epinephrine (p less than 0.01), and 16% after t..View full abstract
