CPAP oxygen therapy device helps Covid-19 flare-up | New


This oxygen supply is also known as Continuous Positive Airway Pressure (CPAP). The device has been shown to be well tolerated by users and able to aid oxygen flow without inducing hypoxia (low oxygen levels) or hypercapnia (build-up of carbon dioxide in the blood).

Respiratory aid was developed with low cost in mind, an ideal solution to meet clinical demands in low-resource healthcare settings affected by the pandemic.

A simple design involving the use of a simple electric fan to generate airflow can alleviate the lack of access to high pressure air and oxygen supplies.

The device was developed by staff at Leeds University, Leeds Teaching Hospitals NHS Trust, Bradford Teaching Hospitals NHS Foundation Trust, Medical Aid International and Mengo Hospital in Uganda.

Speaking on their innovation, Nikil Kapur, Professor of Applied Fluid Dynamics at the University of Leeds, said: “By taking the frugal innovation approach, we have been able to redesign an important piece of medical equipment. so that it can function effectively in more resource-poor health care. The settings.”

He also said that once the complexity is removed, the device will operate in environments where the oxygen supply must be maintained.

With conventional CPAP machines costing around £ 600, ventilators used in intensive care units can cost over £ 30,000. In comparison, the new prototype has a total component cost of around £ 150.

Dr Tom Lawnton, intensive care and anesthesia consultant, Bradford Teaching Hospitals NHS Foundation Trust, and research team member, said: Patients in need of advanced intensive care such as ventilators. “

He also said that simple CPAP devices like this can help reduce global health care inequalities.

Following a British study implying that CPAP is a positive solution for suffering from Covid-19, the World Health Organization has encouraged the development of such low-cost respiratory aids, particularly for countries where patients are suffering from Covid-19. health systems lack adequate funding.

Such health systems rely on large oxygen concentrators that remove nitrogen from the surrounding air and provide a low pressure oxygen supply.

Lead author of the study, Dr Pete Culmer, associate professor at the School of Mechanical Engineering in Leeds, revealed that the prototype was specifically designed to work with oxygen concentrators.

The ventilation system allows for safe oxygen flow, allowing the patient’s airways to open so that oxygen can enter tiny air sacs in the lungs. The oxygen concentrator can then be used to enrich this air flow with oxygen.

The article reported that healthy volunteers who participated in the trial had blood oxygen saturation levels between 96% and 100% and that the range of carbon dioxide at the end of exhalation was within the accepted healthy limits.

Another trial, this time involving sick patients, will start next month (September) at Mengo Hospital in Kampala, Uganda.
