Oxygen therapy encompasses all those clinical treatments used in cases of respiratory insufficiency and to prevent situations of hypoxia.

Oxygen therapy or respiratory therapy must be administered following the indications of a physician, and it is an essential part in treating respiratory pathologies like asthma or in some versions of and bronchitic emphysematous diseases.

Generally two main types of oxygen therapy are used: low flow and high flow.

  •          High flow systems are considered of fixed flow concentration, because in this system all the supplied oxygen reaches the patient. Amongst the main tools used in this type, the Venturi mask stands out, which has different concentrations of oxygen for a higher reliability.
  •          In low flow systems, a certain quantity of oxygen can escape so they are known as variable flow systems. In this type of oxygen therapy it is included the use of anasal cannula.

The oxygen maskcovers nose and mouth, so it must be removed when eating; this implies more comfort for the patient. There are also masks with a reservoir bag designed to store the gas coming from the oxygen therapy device or source, in addition, the latter is usually placed away from the patient through an extender oroxygen line, so it grants a higher comfort to the patient when moving, and allows for being as far as possible from the annoying noise these devices emit.



    The goal of the oxygen masks is to apply oxygen therapy. It can be used in cases of acute or chronic hypoxia.


    A nasal cannula is a plastic tube which is placed around the ears of the patient; it has two small tips in the tube to be inserted in the nostrils. This device is used to administer a high oxygen flow to a patient breathing with minor problems.


    They are extenders or oxygen tubes that will let the patient to move or keep the oxygen therapy devices up to 10 meters away, which allows for walking freely in a small radius without having to move the device, or to keep it out of the bedroom when sleeping if the noise from the device results annoying.


    A Guedel airway is a simple tube with a curved shape, semi rigid, and usually made of plastic material, intended to be placed in the oropharynx. It keeps the airway exposed, preventing the tongue and the pharynx musculature to obstruct the air flow. It is an essential item to avoid serious injuries that can happen when the oxygen supply to the brain is interrupted for several minutes.


    Nasal aspirators are devices for aspiring the mucus that obstruct the airways, frequently used in pediatrics.

    These snot aspirators include a container (25 ml capacity) scaled from 0 to 25 ml for every reference, and a tracheal suction catheter.

    The pediatric snot aspirators come with two suction catheters. Depending on the child size, the user can replace the tracheal suction catheter installed on the device for the smaller probe.
