小鼠等小动物呼吸运动的描记以往多用胸部悬线法和体容积描记法(改良Teschendorf法),但这些方法由于其灵敏度较差,且操作较繁,不易描记出满意的波形。近期有用Dress流量计测量动物呼吸的潮氧量作为呼吸深度的指标,但因小鼠等小动物呼吸微弱,呼吸频率又快,故此法亦不够理想。因此大大防碍了小鼠等小动物作为研究呼吸功能和分析药物对呼吸中枢影响的应用。 Breathing of mice and other small animals in the past traditionally used chest suspension line method and volume plethysmography (modified Teschendorf method), but these methods due to its poor sensitivity, and the operation is complicated, not easy to trace the satisfactory waveform. The recent use of the Dress Flowmeter to measure the amount of oxygen in the animal’s breath as an indicator of respiratory depth has not been satisfactory because of the weak breathing and the fast breathing rate of small animals such as mice. Thus greatly hindering the use of mice and other small animals as respiratory applications and analyzing the effects of drugs on the respiratory center.
