Abstract

A system for calibrating the Respitrace impedance plethysmograph was developed with the capacity to quantitatively verify the accuracy of calibration. LabVIEW software was used on a Macintosh II computer to create a user-friendly environment, with the added benefit of reducing development time. The system developed enabled a research assistant to calibrate the Respitrace within 15 min while achieving an accuracy within the normally accepted 10% deviation when the Respitrace output is compared to a water spirometer standard. The system and methods described were successfully used in a study of 10 subjects smoking cigarettes containing marijuana or cocaine under four conditions, calibrating all subjects to 10% accuracy within 15 min.

摘要

开发了一种用于校准Respitrace阻抗体积描记器的系统，该系统能够定量验证校准的准确性。在Macintosh II计算机上使用LabVIEW软件创建了一个用户友好的环境，其额外的好处是减少了开发时间。所开发的系统使研究助理能够在15分钟内校准Respitrace，同时当将Respitrace输出与水肺量计标准进行比较时，实现了在通常可接受的10%偏差范围内的准确性。所描述的系统和方法成功地用于一项对10名受试者在四种条件下吸食含有大麻或可卡因香烟的研究中，在15分钟内将所有受试者校准至10%的准确度。
