Medical Venturi Oxygen Mask With Different Color Diffuser For Curing Pneumonia

Medical Multi-Vent Mask With 2 Color Diffuser For Curing Pneumonia

Venturi masks are commonly used in the hospital setting to deliver controlled percentages of oxygen.

This is important for those at risk of hypercapnic respiratory failure and to accurately assess ventilation and gas exchange.

What does a Venturi mask do for a patient?
The Venturi mask, as all the aforementioned low-flow systems, provides oxygen at flow rates that are lower than patients' inspiratory demands; thus, when the patient's inspiratory flow exceeds the gas flow rate from the mask, room air is entrained.

Why is Venturi mask used for COPD?
Venturi masks, calibrated to deliver Fio2 between 24% and 50%, are most useful in patients with COPD because the Po2 can be titrated, thus minimizing the risk of CO2 retention. Oxygen saturation of hemoglobin of approximately 80% to 90% can be achieved with nonbreathing masks.

What is the difference between oxygen mask and Venturi mask?
Nasal cannulas and simple face masks are typically used to deliver low levels of oxygen. Another type of mask, the Venturi mask, delivers oxygen at higher levels. Sometimes nasal cannulas are also used to deliver high levels of oxygen.
