The global market of oxygen humidifiers is experiencing a steady growing due to the contribution of these devices to reducing invasive oxygen therapy and other complex interventions. Oxygen humidifiers are in demand at the treatment of dehydrated and immobile patients, as well as patients with tracheostomy and those receiving high-flow oxygen. The market prospects are wide, and it will continue to expand due to advantages and ease of use.
Technological progress allowed oxygen humidifiers to pass gases at the body temperature, and the flow can be electronically controlled. Another factor is multiply clinical trials, which are carried out by the medical community - these technology is economically viable. The global market for humidifiers of medical gases is characterized by the presence of numerous players, and the competition between them will increase in the coming years.
Depending on the nature of the process, the market of oxygen humidifiers is divided into active humidification through a heated humidifier (HH) and passive moisture through a moisture exchanger (HME). Respiratory humidifiers are used in various medical institutions, such as nursing centers, home care, emergency care and hospices.
High-precision, temperature-controlling oxygen humidifiers are particularly in demand in pediatric and neonatal practice because the walls of the nasal cannula or the endotracheal tube interfere with the natural heating of the respiratory gas.
In fact, the high-flow therapy is a new therapy and is widely used. High-flow oxygen therapy is a form of respiratory support when moistened oxygen, in combination with compressed air, is delivered to the patient at a rate higher than with conventional oxygen therapy. Traditional therapy goes with a speed of up to 16 l/min, and a high flow rate - up to 60 l/min.
Nasal high-flow therapy means the supply of warmed and moistened gas through the nasal cannula. Thus, the incoming gas flow is higher than the patient's breath on inhalation. In neonatology, a flow of more than 1 l/min is considered high flow therapy, whereas at adults, higher values should be used.
High-speed oxygen therapy is consist of a blender connected to a wall outlet, an oxygen humidifier, a heated tube and a nasal cannula. A constant warm, moistened flow improves alveolar gas exchange and reduces the load on the respiratory muscles. Therapy with a high oxygen flow significantly reduces the anatomical dead zone in the bronchi, creates a reservoir with a high FiO2 in the nasal cavity and ultimately improves gas exchange and reduces the burden on the respiratory muscles.
If flow of the respiratory gas exceed the inhaled flow, then the supply of air through the nose can be reduced or stopped, unlike traditional therapy with low flow through the nasal cannula. As a result, oxygen saturation and oxygen delivery efficiency can be improved.
Other positive effects of oxygen therapy with high flow and humidification:
High-flow oxygen therapy is usually used in patients with acute respiratory insufficiency and chronic conditions and at non-intubated patients.
