A rising need for better oxygen concentrators as the fight againstCOVID-19 develops in recent which took a lot of effort to be developed and currently it holds the expectations of many.
Pulse oximetry is extensively utilized in critical care, few researchers have looked at its utility in clinical decision making. The titration of fractional inspired O2 concentration (FIO2) in ventilator-dependent patients is one area where pulse oximetry may be effective.
With A Revolutionary Design For Portable Concentrators, Reliable Oxygenation Is Possible
Due to the surge in cases of Covid-19 cases in different states many patients need to go on a ventilator also and hence the demand for oxygen also increased suddenly. In such situations, these portable concentrators can be a better and more viable option for many patients.
These concentrators are better with swift functions and portable designs as well as low weight which makes them easy to move in any part.
Many of the patients who are not admitted to hospitals can also go for such portable oxygenation that can help them keep away from reduced oxygen levels.
Unfortunately, there are no established recommendations for this use, and a survey of intensive care unit directors revealed that they used a wide range of target O2 saturation (SpO2) values.
While health workers around the world care for patients sick with SARS-CoV-2 and its numerous variants, medical oxygen shortages continue to wreak havoc on already overburdened hospitals.
Also, while portable oxygen concentrators have helped many people with respiratory problems, they don’t always produce enough medical oxygen to meet the fluctuating demands of a patient with deteriorating symptoms, forcing them to return to the hospital.
Other respiratory disorders such as chronic obstructive pulmonary disease, pneumonia, and asthma would benefit from oxygen concentrators based on their design, according to the researchers. Asthma is a chronic inflammatory illness of the airways that causes wheezing, dyspnea, chest tightness, and coughing on a regular basis.
Airway hyperreactivity, airflow restriction, and chronic illness are all caused by airway inflammation. COPD, CHF, foreign body aspiration, anaphylaxis, epiglottitis, tracheobronchitis, reactive airway disease, viral respiratory infections, and vocal cord dysfunction are all examples of chronic obstructive pulmonary disease (COPD).
In the United States, pneumonia is the sixth leading cause of mortality overall and the leading cause of death from an infectious disease. To improve the design of present medical oxygen concentrators, Arora looked at three different types of zeolites: LiX, LiLSX, and 5A.
He then ran a physics-based simulation that modeled various zeolites features as well as characteristics of the oxygen concentrator, such as the size of the adsorption chamber and the various stages of the adsorption process.
Then, using a Texas A&M high-performance computer cluster, he altered all of the simulation’s inputs at the same time to find the most optimal operating range for a compact, easy-to-transport, high-performance medical oxygen concentrator.
However, given their many benefits, oxygen concentrators are frequently designed with fixed specifications, restricting their ability to meet oxygen demands induced by changes in a patient’s medical condition or activities. For example, a patient’s oxygen needs may vary in terms of flow rate and purity, and present oxygen concentrators cannot be used for numerous patients with highly varying breathing requirements in the same hospital setting.
According to the researchers, their research is a preliminary step toward developing portable cyber-physical devices for home usage that can adjust oxygen supply based on the patient’s demands.
As a patient’s symptoms deteriorate, built-in algorithms might assess data from oxygen sensors to forecast whether more ventilation is required, and then send that information to off-site clinicians, who can then use their judgment to change settings on the medical oxygen concentrator remotely.
