3 Things You Need To Consider When Using A Body Box During COVID-19

Plethysmography, or lung function testing, faces a whole new set of safety considerations in the COVID-19 world.

ERS COVID-19 Guidelines for Plethysmography

According to a recent statement from the European Respiratory Society (ERS), “Lung function tests (LFTs) often generate aerosols in the form of droplets… LFTs therefore pose a considerable risk for the spread of infection to individuals and surrounding surfaces within and around the test areas even in asymptomatic patients.”

So what does this mean about using a Body Box?

Disinfection

The ERS explicitly states that lung volumes & DLCO can be performed in a Body Box only “if droplet contamination can be contained, and local national guidelines support this.” Is it realistic to be able to contain droplets in a Body Box? We’re not sure.

Long downtime between patients

The ERS statement emphasizes that enough time needs to be allowed between patients for cleaning/decontamination of testing equipment, recalibration, and 15+ minutes of room ventilation. For a body box, they estimate that this will take between 30 to 60 minutes. That’s a lot of downtime.

Cabinless plethysmography with the MiniBox+ is safe with minimal downtime

Because it’s a cabinless device, there’s no issue of droplet contamination with the MiniBox+, and disinfection is easily accomplished in just a few minutes by an exterior wipedown.

Also – since the MiniBox+ self-calibrates after each test, there’s no need to re-calibrate manually.

Lastly – it’s portable. After wiping down the exterior, the MiniBox+ can be easily moved into another room for testing the next patient while the previous room is ventilated for 15+ minutes. In other words – there’s pretty much no downtime between patients.

Here’s a summary of the implications of the ERS Group 9.1 Guidelines for Plethysmography:

Category Body Box MiniBox+
Lung Volumes & DLCO May be performed ONLY “if droplet contamination can be contained, and local national guidelines support this.”
  • Disinfecting is achieved by wiping down the exterior of the device.
Expected downtime between patients 30-60 minutes for post-test cleaning/decontamination procedure, including device re-calibration and 15+ min for room ventilation.
  • 5 minutes for post-test cleaning/decontamination wipedown.
  • No need for device re-calibration.
  • Mobility allows for uninterrupted patient flow during room ventilation.

 

In other words, cabinless plethysmography with the MiniBox+:

  • Is compliant with all ERS Group 9.1 safety recommendations for COVID-19
  • Has minimal downtime between patients
