Pulmonary capillary blood flow (Qc) was measured by a nitrous oxide uptake technique using a capacitance-plethysmograph to measure pulmonary volume changes. One hundred and four paired Qc and total cardiac outputs (Qt) were measured in 13 normal mongrel dogs. The mean Qc was 0.101 +/- 0.020 1-min -1-kg-1 while the mean Qt, measured by dye dilution, was 0.117 +/- 0.025 1-min-1-kg-1. This technique minimizes subject trauma and provides a method for repeated pulmonary capillary blood flow determinations in acute or chronic studies.
采用一氧化二氮摄取技术，使用电容体积描记仪测量肺容积变化，从而测定肺毛细血管血流量（Qc）。在13只正常杂种犬身上测量了104对Qc和总心输出量（Qt）。平均Qc为0.101±0.020升/分钟/千克，而通过染料稀释法测得的平均Qt为0.117±0.025升/分钟/千克。该技术将对实验对象的创伤降至最低，并为急性或慢性研究中重复测定肺毛细血管血流量提供了一种方法。
