Design and Validation of a Research-Grade Waterpipe Equipped With Puff Topography Analyzer.

ABSTRACT:

Introduction

Worldwide, commercially available waterpipes vary widely in design and durability, including differences in fabrication materials, degree of leak-tight fit, and flow path diameter. Little is known about how the components of the waterpipe may influence puffing behavior and user's exposure to toxins. To systematically evaluate exposure, it is necessary to use a standardized research-grade waterpipe (RWP) when conducting clinical and laboratory-based trials.

Methods

We developed a RWP that is configured with an in-line topography system which allows real-time measurement and recording of the smoke volume drawn through the RWP. The RWP was calibrated across the flow rate range expected for waterpipe tobacco smoking and the calibration was verified for known puff vo
