Anthropometric Data Collection in the Human Nasal and Oral cavity

Abstract

This paper examines new methodologies that may be used for the process of the Anthropometric data collection in the Human Respiratory Tract (HRT). The geometric dimensions of internal human anatomy in the nasal and oral cavity varies among the individuals but has the same structure overall. The volume of the flow differs widely with respect to the dimensions of the nasal and oral cavity. The process of defining a definite geometry is a complex task as the shape or size of the cavity differs widely. Several methods which are published in literature define the geometry by determining its physical characteristics. The existing methodologies focus on the internal portion of the nasal and oral cavity extending up to the trachea and beyond. A methodology is proposed to measure the characteristic dimension of the human nasal and oral cavity at the inlet/outlet points which are classified as internal measurements.
