When a fluid (either gas or liquid) travels through an hourglass-shaped pipe, there is a reduction in pressure of the fluid in the throat of the pipe, and the velocity of the fluid increases in the throat area, this is known as the Venturi effect. Depending on the Venturi effect, a medical device or Venturi mask is used to deliver a known concentration of oxygen to the patient under controlled oxygen therapy. Entrapping the ambient air, the Venturi mask delivers constant air flow to the ... Read more
