Getting to know the HFNC respirator for all Covid-19 patients

KOMPAS.com – Indonesian scientists have developed a High Flow Nasal Cannula (HFNC) breathing apparatus to help treat Covid-19 patients.

The team from the Indonesian Institute of Sciences (LIPI) and the University of Indonesia (UI) developed the HFNC tool.

LIPI succeeded in developing a tool called Gerlink LIPI High Flow Nasal Cannula-01 (GLP HFNC-01) in June 2020. Meanwhile, UI succeeded in developing HFNC in January 2021.

Basically, the HFNC developed by LIPI and UI aims to help early-stage Covid-19 patients.

LIPI Deputy for Engineering Agus Haryono said, GLP HFNC-01 was intended to assist health services in meeting the need for tools that can help treat respiratory disorders in Covid-19 patients.

“This device, also known as the High Flow Nasal Cannula (HFNC), is the first to successfully pass the test from the Health Facility Security Center of the Ministry of Health,” Agus said in a written statement, Wednesday (17/6/2020).

LIPI has been conducting research for this innovation since April 2020, which then succeeded in producing a nasal cannula or breathing apparatus to deliver oxygen through clear, transparent and flexible tubes.

Head of the Industrial Automation Research Group of the LIPI Electric Power and Mechatronics Research Center, Hendri Maja Saputra, said that technically the working system of this tool is high flow using a venturi tube system based on inflow narrowing.

According to him, this tool is very useful for Covid-19 positive patients, as well as those with the status of People Under Supervision (ODP) and Patients Under Supervision (PDP), as an early stage assistance if the patient is still able. breathe alone.

“This device prevents patients from failing to breathe and does not have to be incubated using an invasive ventilator,” said Hendri.

UI develop HFNC

In January 2021, the University of Indonesia also announced its success in developing a High Flow Nasal Cannula (HFNC) breathing apparatus to help treat Covid-19 patients in Indonesia who are prone to hypoxia.

This HFNC tool was developed by a team from the Faculty of Engineering, University of Indonesia (FTUI) and the Faculty of Medicine, University of Indonesia (FKUI) in collaboration with the Friendship Hospital and the Indonesian Lung Doctors Association (PDPI).

“This tool works by utilizing the principle of high-flow oxygen therapy and is intended for treating COVID-19 positive patients at an early stage,” said the Dean of FTUI, Dr. Ir. Hendri DS Budiono in his statement.

As reported by the news agency Among, January 22, 2021, HFNC breathing apparatus is a high flow oxygen therapy device.

The High Flow Oxygen Therapy (HFOT) method is a non-invasive method that can be used to assist breathing in early-stage Covid-19 patients.

One way to deliver high-flow oxygen to the patient is with a nasal cannula. The workings of this tool utilize the HFOT principle which is often referred to as HFNC.

Indonesia still relies on imported raw materials and there are no HFNC products that can meet domestic needs.

How HFNC works

HFNC UI development team member, Dr. Ing. Ridho explained, HFNC works by flowing air with a high oxygen content (21-100 percent) and a flow rate of up to 60 liters per minute.

This high-speed flow of oxygen is passed through the heating chamber until there is an increase in relative humidity (RH) and temperature until it reaches the patient’s body temperature.

“Adjustment of humidity and temperature to the patient’s condition is intended to maintain patient comfort,” said Ridho.

The Dean of FKUI, Prof. Dr. dr. Ari Fahrial Syam highly appreciates the manufacture of the HFNC device, considering that the Covid-19 infection makes patients susceptible to experiencing hypoxia or conditions of lack of oxygen in the body.

“So in hypoxic conditions, additional oxygen therapy is needed,” said Ari.

Reported Kompas.com January 19 2021 edition, demonstrations and functions of the HFNC breathing apparatus were carried out on January 7, 2021 at the Persahabatan Hospital Respiration Simulation Center Building.

From the demo results and the performance of the functions that have been carried out, there are several things that will be done to speed up the work of HFNC so that it can be used.
