Non-rebreather masks (also called reservoir masks) are used to treat patients with a significant degree of hypoxia (moderate to severe). Non-rebreather masks can deliver high FiO2 concentrations as the oxygen is inhaled from both the
A non-rebreather mask is an oxygen delivery device with a one-way valve so the patient does not inhale the same air they exhale. A non-rebreather mask works similarly to a partial rebreather mask in terms of how you will operate it.
Oxymizer – contains a small reservoir that allows higher flow rates and higher effective FiO 2 to be delivered compared to nasal cannula. It also contains thicker nasal prongs which reduces
Oxygen use has extended from inpatient to outpatient settings for patients with chronic pulmonary diseases and complications of hypoxaemia. This article presents an overview of oxygen devices (oxygen concentrators, compressed gas cylinders and liquid oxygen) and delivery systems (high- and low-flow).
A variety of devices are available for oxygen delivery, such as nasal cannulas, reservoir cannulas, and transtracheal catheters. Each method has unique features that recommend for or against its use in the individual patient (table 1 and table 2).
The proximal end consists of a venturi device which are color coded and marked with the recommended oxygen flow rate to provide the desired oxygen concentration.
Hypoxia machines operate by precisely controlling the oxygen concentration in the air delivered to an individual. The most common method involves nitrogen generation, where ambient air is drawn into the machine, and oxygen is filtered out, resulting in air with a lower percentage of oxygen.
This article describes different types of non-invasive oxygen delivery devices including indications for use, how to setup and titrate devices, and how to choose between different device types.

Ejection devices are most suitable for use at organizations which can be constantly supplied with compressed nitrogen. Gas separation devices are suitable for the in-patient facilities that are not supplied with compressed nitrogen.
Supplementary oxygen to correct hypoxia can be delivered by a variety of oxygen delivery devices. It is important to be familiar with different devices and the situations in which they are used. Each oxygen delivery device will deliver a different fraction of inspired oxygen (FiO2).
Therefore, these oxygen delivery systems do not allow for accurate calculation of the inspiratory oxygen fraction (FIO2). High-flow oxygen delivery systems provide higher oxygen flows and the FIO2 is stable and is not affected by the patient's type of breathing.
Compared to continuous oxygen flow, oxygen-conserving devices deliver pulsed oxygen during inspiration only, triggered by the patient's inspiration. These “demand” oxygen delivery systems enable cylinders to last longer, since the oxygen waste during expiration is reduced.
Hypoxia is insufficient tissue oxygenation. Arterial blood flow is what delivers oxygen to body tissue, so hypoxemia (low oxygen in arterial blood) can lead to hypoxia (low oxygen in the tissues). As a nurse, it is important to know the early vs. late signs of hypoxia.
In hypoxaemic chronic obstructive lung disease, continuous oxygen therapy is associated with a lower mortality than is nocturnal oxygen therapy [1 – 5]. Oxygen concentrators do not need to be refilled. The concentrators run on electrical power and thus supply an unlimited amount of oxygen.
A variety of technical implementations for this treatment has been tested and used in recent decades, including hypobaric chambers, normobaric reduced oxygen rooms and mask-system hypoxicators, which produce hypoxic air in various ways.
