bernoulli principle
The main advantage of the Venturi mask is?
Venturi tube is used to for flow measurement. It work on the principle of Bernoulli Equation.
Yes, it can.
COPD patient
no
Place a tee and mouth piece together and place into the hole in the mask with the neb in the tee.
The basic principle is the carb holds gas in a float bowl with an exit needle to the venturi. When this exit needle is opened by pressing the accelarator, the air valve at top of venturi also opens, thus mixing air and gas in the venturi and admitting the mixture into the intake manifold.
Yes, the flow rate of oxygen delivered through a venturi mask can affect the fractional inspired oxygen concentration (FiO2) that the patient receives. Higher flow rates can increase the FiO2 by providing more oxygen to mix with room air as it flows through the mask's entrainment ports.
Multi Flow Venturi Mask is used by the patients suffering from asthma or other breathing problems and is an ideal choice for oxygen therapy. It is provided with 6 different connectors, each with distinct marking for required flow of oxygen and different color coding. Multi Flow Venturi Mask fits snugly over the nose and mouth as well as delivers supplemental oxygen at the precise concentration. A venturi mask should be made up of medical-grade PVC, must be 100% latex free and should have smooth edges for patients' comfort and safety. Medical device manufacturing companies like Life-O-Line Technologist offers six color coded diluters for six concentrations: 24%, 28%, 31%, 35%, 40%, & 50%. A variable venturi connector is there to ensure precise, accurate or predicted concentration of oxygen with single unit. Some venturi masks also come with a unique design of nebulizer chamber with mask that nebulizes the patient even in supine position. These venturi masks are sterile, disposable, and non-pyrogenic.
difference in air pressure at the venturi throat and the air inlet.
Don't think so - all my references show it's to do with air pressure in constricted flow. Check you question. You are correct. The Venturi effect has nothing to do with light. It is the ability to create positive and negative pressures with various tubes. Siphons work on a venturi principle for example.
increase in air velocity in the throat of a venturi causing an increase in air pressure.
