However, while glottal vibrations were extensively studied during human phonation, the realistic glottal motion during breathing is poorly understood. Therefore, most ...
Realistic glottal motion and airflow rate during human breathing The glottal geometry is a key factor in the aerosol delivery efficiency for treatment of lung diseases. However, while glottal vibrations were extensively ... Adam,Scheinherr,Lucie,... - 《Medical Engineering & Physics》 被引量: 14...
Natural human exhalation flows such as coughing, sneezing and breathing can be considered as ‘jet-like’ airflows in the sense that they are produced from a single source in a single exhalation effort, with a relatively symmetrical, conical geometry. Although coughing and sneezing have garnered ...
Answer and Explanation:1 Respiratory gas exchange otherwise known as breathing is a purely physical process that occurs without energy expenditure. It takes place by simple... Learn more about this topic: Breathing Rate: Definition, Calculation & Regulation ...
Airway flow dissipates only a few percent of the total body work during normal breathing, so branching patterns deviate from minimum energy loss to also optimize other physiological needs. Studies of airway performance often record some measure of expiration, such as FEV1 (Forced Expiratory Volume ...
For short separation distances between breathing sources the interaction between breaths is a key factor in the airborne cross-infection for all the breathing mode combinations studied. However, for long distances the general airflow conditions in the room prove to be more important. Graphical ...
This is the first-ever study of the transport and deposition of aerosols in a realistic human lung model employing transient flow rate for realistic aerosol breathing patterns. The measured transient airflow rate is used as the inlet condition in the numerical simulations, and the particles are ...
Simulation of airflow and aerosol deposition in the nasal cavity of a 5-year-old child As a human grows from birth to adulthood, both airway anatomy and breathing conditions vary that alter the deposition rate and pattern of inhaled aerosols... J Xi,X Si,JW Kim,... - 《Journal of Aero...
For example, name one human being who doesn’t need the most basic item to live as a human being – air to breathe. [Breathing is non-negotiable. Not being able to breathe is a deal-breaker. No breathing means no continued existence in this physical world.] We have built societies all...
