Venturi Mask

The Venturi mask is a high-efficiency, high-flow oxygen delivery device developed based on the Venturi effect, specially designed for precise oxygen therapy. When oxygen passes through the built-in narrow channel of the device, negative pressure forms around the jet airflow, actively drawing a fixed volume of air in through the mask’s open edges. By adjusting the size of the mask’s side slots, the air-oxygen mixing ratio can be flexibly regulated, stably delivering a precise oxygen concentration ranging from 24% to 60%. It also effectively prevents carbon dioxide rebreathing, providing stable and reliable support for oxygen therapy.

Core Product Features

The Venturi mask is rigorously designed for both utility and safety, with the following key strengths:

● 7 color-coded oxygen nozzles enable quick stepwise oxygen concentration adjustment to meet diverse patient oxygen therapy needs.

● Crafted from medical-grade lightweight PVC, the mask is soft and facial-contoured, significantly reducing pressure marks from prolonged wear. Its double head strap design allows tightness adjustment per patient head size for secure, non-slip fitting.

● Dedicated exhaust ports on the mask sides accelerate exhaled gas discharge, further lowering the risk of carbon dioxide retention.

● Built-in precision Venturi valve flexibly adjusts oxygen flow rate based on patient breathing conditions for accurate oxygen concentration control.

● Disposable for single use only, it eliminates cross-infection risks at the source and dispenses with cleaning and disinfection, ensuring hassle-free usage.

Product Parameters

Application Scenarios

With its advantage of precise oxygen control, the Venturi mask is widely used in medical institutions at all levels and home oxygen therapy scenarios. It is especially suitable for:

● Patients with Chronic Obstructive Pulmonary Disease (COPD)

● Patients with hypoxemia complicated by hypercapnia

● Postoperative recovery patients requiring adjuvant oxygen therapy

● Patients with hypoxia caused by respiratory system infections

Whether for precise oxygen therapy in clinical intensive care or daily needs of long-term home oxygen therapy, this device delivers stable oxygen support to meet oxygen therapy demands across different scenarios.

Usage & Key Precautions

Usage Steps

1.Select the corresponding color-coded Venturi mask based on the patient’s oxygen therapy needs, or adjust the knob at the mask-tubing connection to set the target oxygen concentration.

2.Determine the appropriate gas flow rate according to the patient’s respiratory rate and depth.

3.Adjust the oxygen source flow rate as instructed in the manual to ensure optimal oxygen therapy effect.

Key Precautions

1.Conduct a comprehensive assessment of the patient’s respiratory status and confirm gas flow rate parameters before use.

2.Check the mask’s sealing performance before and during use to avoid compromised efficacy due to air leakage.

3.For special patients (e.g., those with COPD), closely monitor their bodily responses throughout therapy to prevent respiratory center depression caused by excessively high oxygen concentration, ensuring oxygen therapy safety.
