Methods: Oxygen-dependent patients with chronic, stable respiratory disease were recruited to compare the OxyMask and Venturi mask in a randomized, single-blind, cross-over design. Baseline blood oxygen saturation SaO2 was established breathing room air, followed in a random order by supplemental oxygen through the OxyMask or Venturi mask. More related articles.

Another type of mask, the Venturi mask, delivers oxygen at higher levels. Sometimes nasal cannulas are also used to deliver high levels of oxygen.
Nasal cannulas and face masks are typically used to treat people who have respiratory conditions such as:. They can also be administered in hospitals to people who have experienced trauma or acute conditions such as heart failure. Learn more: Oxygen therapy ». Before prescribing treatment, your doctor will perform some tests to measure how much oxygen you already have in your blood. They may take a sample with a needle or use a sensing device. When placed against your finger or toe, the sensing device, called a pulse oximeter, uses light to measure the amount of oxygen in your blood.
No blood draw or needle is necessary. Oxygen can be administered with nasal cannulas or face masks in hospitals, clinics, or specialized care facilities. It can also be administered in a home setting or even on the go. Venturi masks provide a constant, preset level of oxygen. Explain the difference between low- and high-flow oxygen systems.
The reservoir bag on a non re-breather mask and a partial re-breather mask must always be kept partially inflated. Previous: 5. Next: 5. Share This Book Share on Twitter. Types of Oxygen Equipment. Additional Information. Nasal cannula consists of a small bore tube connected to two short prongs that are inserted into the nares to supply oxygen directly from a flow meter or through humidified air to the patient.
It is used for short- or long-term therapy i. Applying a nasal cannula Nasal cannula. A mask fits over the mouth and nose of the patient and consists of exhalation ports holes on the side of the mask through which the patient exhales CO 2 carbon dioxide. These holes should always remain open.
The mask is held in place by an elastic around the back of the head, and it has a metal piece to shape over the nose to allow for a better mask fit for the patient. Humidified air may be attached if concentrations are drying for the patient. Simple face mask. Consists of a simple mask and a small reservoir bag attached to the oxygen tubing connecting to the flow meter.
With a re-breather mask, there is no re-breathing of exhaled air. It has a series of one-way valves between the mask and the bag and the covers on the exhalation ports.
On inspiration, the patient only breathes in from the reservoir bag; on exhalation, gases are prevented from flowing into the reservoir bag and are directed out through the exhalation ports. Non re-breather mask.
