关于吸烟的定量数据通常包括抽吸指数的测量，例如抽吸量、流量和持续时间。工作人员使用微型流量（呼吸速度描记器）头来监测香烟烟雾的流量，并将其整合以获得抽吸量。然而，如果在一个固定温度下校准流量头，并且不考虑抽吸期间烟雾温度的变化，则在抽吸体积的测量中引入误差。为了研究该误差的大小，已经测量了已知的抽吸体积。对烟温变化的校正和所用流量头的仪器校准进行了描述，并已应用于卷烟抽吸量测量。
Quantitative data on cigarette smoking often include measurements of puffing indices such as puff volume, flow and duration. Workers have used miniature flow (pneumotachograph) heads to monitor the flow of cigarette smoke and integrated this to obtain puff volume. However, if flow heads are calibrated at one fixed temperature and account is not taken of variations in smoke temperature during puffing, an error in the measurement of puff volume is introduced. In order to investigate the magnitude of this error, known puff volumes have been measured. Corrections for variations in smoke temperature and instrument calibration for the flow head used are described and have been applied to the cigarette puff volume measurements.
