Additional fresh air is an critical facet of helpful care, both in a medical facility and at home. A Venturi cover up -- also known as an air-entrainment cover up -- is a medical fresh air delivery cover up that runs on the circulation gauge to provide a precise quantity of fresh air. Venturi covers are indicated for use in those individuals experiencing serious or acute respiratory problems, or when an arterial blood vessels gas result indicates a need.

Wash your hands with soap and hot water. Hygiene is crucial when handling fresh air covers and supplemental fresh air tube.

Remove the cover up and fresh air tube from the appearance. Examine the cover up and tube -- looking for breaks and staining. Eliminate any covers or tube that are not unchanged.

Select the appropriate circulation device according to a doctors purchases. Venturi valves are colored according to the quantity of fresh air they provide in liters for each moment.

Most manufacturers follow a standard color chart. Refer to the manual of the cover up, if you are uncertain.

Blue valves provide 2 liters of fresh air for each moment at a 24 % focus. White valves provide 4 liters for each moment at a 28 % fresh air focus. Yellow valves provide 6 liters for each moment at a 35 % fresh air focus. Red valves provide 8 liters for each moment at a 40 % fresh air focus. Green valves provide 12 liters for each moment at a Sixty % fresh air focus.

Assemble the cover up by placing the circulation device into the cover up. Connect the fresh air tube to the cover up and the supplemental fresh air source.

Place the cover up on the face, so that the small pointed end of the cover up sets on the link of the nose. The larger curved portion of the cover up should rest on the chin area. Take the rubber group carefully over the back of the head to secure the cover up in position.

Pull the ends of the rubber group for making adjustments to the cover up, so that it fits perfectly. Ensure that the cover up and bands are not preventing venous blood vessels circulation. Signs of obstructed blood vessels circulation are pain, numb feeling, and staining of the area.

Turn on the supplemental fresh air -- adjusting it slowly -- until you reach the desired therapy level.

Check the tube and cover up for leaking. Tighten up airline connections and cover up fit, as needed to fix leaking.
Tips

In a medical facility setting, Venturi masks are for single individual use; discard additional authorities, only after the affected person has been released.
