Modeling the pharyngeal pressure during adult nasal high flow therapy

Positive End-Expiratory Pressure Effect of 3 High-Flow Nasal Cannula Devices

“…Parke et al 7,9 confirmed a similar pressure-flow relationship in elective cardiac surgery subjects. However, a computed simulation 16 reported a slightly different quadratic relationship between flow and PEEP, which suggested that air flow played a more important role in the development of PEEP. Moreover, the impact of other factors (such as tidal volume [V T ], lung compliance, or airway resistance) on the PEEP level remains to be elucidated.…”

Effect of airway dynamics on the development of larynx cancer

“…Construction of numerous simulation models for the anatomical structures in different dimensions is quite time‐consuming and technically difficult. In most of the studies, a single anatomical structure model is utilized . We used the model of a male over the age of 50 year based on the general anatomy of the human larynx because the possibility of malignancy is higher in this population.…”

High‐flow nasal therapy – modelling the mechanism

“…Detailed calculations of flow from, and patterns within, the model are then obtained. The first study to use a CFD model to investigate HFNT within the nasopharynx included only the nasal cavity and explored the effect of anatomical features and flow rate on the positive pressure generated . Another CFD study extended the airway model to the proximal trachea, with results validated against a physical model of the same individual airway.…”
