The recent outbreak of COVID-19, caused by the SARS-CoV-2 coronavirus, is posing unprecedented challenges to global health. In this sense, from EVERSENS, we wanted to collect the following information that we hope can answer any questions that may arise regarding the use of evernoa. If you need more information, do not hesitate to contact us.

Is it possible to continue using evernoa during the COVID-19 pandemic?

Before using evernoa, be sure to follow local recommendations for medical testing and implement required containment measures.

 

It is possible to continue using Evernoa, although remember that the presence of respiratory infections can alter FeNO values (1). 

When evernoa is used, extreme caution must be taken, since, even if the patients do not present symptoms, they may be infected with SARS-CoV-2 and, therefore, spread the disease. It is recommended to implement measures that reduce the risk of contagion. Also, after the patient performs the test, it must be ensured that the device is disinfected following the recommendations.

 

It is recalled that evernoa does not require an inhalation through the device, so the patient only exhales through it, thus reducing the risk of cross contamination.

Are the mouthpieces safe against COVID-19?

The mouthpiece used in the evernoa device contain a filter that has been tested by independent laboratories, including evaluating the efficacy against bacteriophage diameter particles of φX174 (25-27 nanometers (nm) - (0.025 - 0.027 μm)).

The size of coronaviruses (including SARS-CoV-2, which causes COVID-19 disease) has been found to be 0.1 to 0.05 μm, much larger than that of the tested particles. Therefore, the filter present in the evernoa mouthpieces is effective against the SARS-CoV-2 virus.

Remember that the mouthpiece that contains the antibacterial filter are for single use and must be disposed according to the applicable regulations.

What measures can I use to reduce the risk of contagion?

The virus that causes COVID-19 spreads through the respiratory droplets of infected people. The risk of contagion decreases considerably while maintaining a certain distance.

 

Evernoa offers the possibility of using a 2m long blower that allows the patient to maintain a safe distance with the device. In this way, the patient's contact with the device is only through the blower handle. Use evernoa with the 2 meter connector and place the device as far away as possible from the patient during exhalation. If your device's pneumatic connector is shorter, contact Eversens.

 

It is recommended that the patient wears disposable gloves when handling the device blower.

 

In the same way, and with the aim of reducing the risk of contagion, the healthcare professional does not have to be present in the same room in which the patient is, since, thanks to Bluetooth or USB connectivity, evernoa View software allows to control the device from a PC remotely. Connect the evernoa device to a PC via Bluetooth and operate it remotely using evernoa View, preferably from outside the room in which the patient remains and always respecting a safety distance of at least 3 meters.

 

Evernoa has an internal battery that allows to use the device without connecting it to the electrical network. Use evernoa device without connecting it to the mains using the battery. Check the condition of the battery and charge the device in an area without risk of contamination.

How do I have to disinfect the evernoa device?

It is recommended the use of a 0.5% sodium hypochlorite solution (in distilled water) for the disinfection (including the SARS-CoV-2 virus, which causes COVID-19 disease) in evernoa device.

 

Carefully disinfect the surface of evernoa device with a cloth dampened in the disinfecting solution (0.5% sodium hypochlorite) after each use, paying special attention to the blower, as this is the area that is closer to the patient. Dispose the used cloth according to the applicable regulations.

 

Do not use alcohol or cleaning agents that contain alcohol or other solvents for cleaning the device. Prolonged exposure to released vapours may damage the cassette sensor.

 

Cleaning instructions for the evernoa device can be found in the user manual.

 

The cleaning and disinfection of evernoa must be carried out together with the current instructions for the prevention of the transmission of viral infections, including COVID-19.
