Oxygen Therapy Device

Oxygen gas which is found in the air is necessary for human life for breathing. While one feels short of breath and the level of oxygen being very low than supplemental oxygen, oxygen therapy is needed as a breathing aid. Home oxygen generator is generally received using tubes wearing in nose or trachea, face mask, or windpipe. From various kinds of oxygen therapy, direct oxygen gas, or liquid stored in a portable tank is used widely all over the world. Besides, oxygen concentrators that How home and hospital oxygen generators work from the room and another device named hyperbaric oxygen therapy in which oxygen gas is pressurized in a room or chamber are used mostly. Though oxygen has a fire risk, this therapy is normally safe and can improve survival rates. Oxygen therapy can play an important role in COVID-19 patients like other breathing-related diseases including pneumonia and asthma.

Oxygen therapy by nasal cannula is a well-known procedure in controlling and preventing respiratory diseases like COVID-19. It provides 5–6 L of oxygen flow per minute [37]. In the nasal cannula system, a small amount of air is continuously vacuumed and transferred to a sensor located on the display [38]. A face mask is also used as an The price of a small oxygen capsule. This mask is fitted with one unidirectional valve for inspiration and two unidirectional valves for expiration. A high oxygen flow is provided to the mask continuously that dilutes the carbon dioxide exhaled by the patient [39]. There are two types of face mask which are used to deliver inspired oxygen (FiO₂) flow. Non-Rebreathing Mask (NRM) provides supplemental oxygen with the rates of approximately 5–10 L/min; while, Partial Rebreathing Mask (PRM) can provide a flow rate of 90% of 15 L/min [40]. Farias et al. [41] described a system in their study that PRM can deliver high oxygen flow than NRM. Nasal cannulas and face masks can be used for COVID-19 patients in low-risk cases. In serious respiratory failure, high-flow nasal cannula (HFNC) is used for its safety and efficacy. It consists of an air/oxygen blender, a nasal cannula, a single heated tube, and an active humidifier [42]. It can deliver about 60 L/min oxygen flow. The use of HFNC limited the mortality in hypoxemic respiratory failure. In addition, it can decrease the risk of subsequent intubation and the need for Intensive Care Unit (ICU) admission [43–45]. It can be commonly used in COVID-19 patients having respiratory failure as a method to administer high concentrations of oxygen.

Another type of oxygen serving device is Hyperbaric Oxygen Therapy (HBOT) [46] in which patients are entered in a special chamber or room to breathe in 100% oxygen in air pressure. The target of this device is to repair and restore normal body function by filling the blood with adequate oxygen. Air pressure is raised 1.5–3 times from the normal air pressure in a hyperbaric oxygen treatment chamber. In such circumstances, patients’ lungs could collect more oxygen than normal air pressure to breathe pure oxygen. This oxygen transports blood all over the body. This helps to kill bacteria and encourages the release of cures of substances such as growth factors and stem cells. There are two types of HBOT (1) Monoplace chamber, (2) Multiplace chamber. Monoplace unit is designed for one person where the patient lies down on a table. It is like a Magnetic resonance imaging (MRI) machine with a long plastic tube. With 100% oxygen, it is slowly pressurized. In contrast, a room designed for several persons is called multiplace chamber. This chamber usually looks like a large room in the hospital where a patient can sit down or lie down. In this case, the oxygen is normally supplied with a thin,https://butcenter.com transparent hood.

Though this therapy is normally a safe procedure, it carries some risk. In certain situations, fire may trigger due to the oxygen-rich atmosphere in the treatment chamber. In addition, a lung may collapse due to certain changes in air pressure [47, 48]. A recent study [49] shows that using additional oxygen up to certain concentrations can improve mortality in certain populations.
