Abstract

The Hewlett-Packard HP47210A Capnometer, a "mainstream" infra-red carbon dioxide analyser, has a sensor in-line with the patient circuit. The calibration apparatus is included within the unit, and an internal microprocessor corrects for the presence of nitrous oxide and varying concentrations of oxygen. Maximum error was 0.37 kPa for carbon dioxide partial pressures less than 5.3 kPa, and less than 3.6% for partial pressures of carbon dioxide greater than 5.3 kPa.

摘要

惠普HP47210A型二氧化碳监测仪是一款“主流”红外二氧化碳分析仪，其传感器与患者回路串联。校准装置包含在仪器内部，内置微处理器可校正一氧化二氮的存在及不同浓度氧气的影响。对于二氧化碳分压低于5.3 kPa的情况，最大误差为0.37 kPa；对于二氧化碳分压高于5.3 kPa的情况，最大误差小于3.6%。
