When a new development cycle begins for a device meant to monitor a patient’s respiratory condition, manufacturers should consider the challenges their design will face with humidity. Humidity is a…
Pulmonary Function Testing (PFT) and Cardiopulmonary Exercise Testing (Metabolic Testing or CPET) have been avaluable source of diagnosis and assessment of respiratory conditions for years. COVID-19 put a strain on theability for labs to be operational and now, as testing has picked up, labs have adopted varying procedures forkeeping patients safe. As you develop solutions to aid in the safe operation of PFT and CPET equipment, we wouldlike to offer insights to support you. Below, you can review five things to consider as you refine your PFT deviceoffering. EXPLORING CHANGES IN MOISTURE CONTROL How will added moisture control affect our test results? Without sufficient moisture control, condensation in the sampling line becomes an issue, slowing readings andaffecting results. The same concept applies to Metabolic Testing. With every exhaled breath, water vapor is being pushedto the sampling line. Nafion™ Tubing removes the vapor, enabling proper measurement andreducing theopportunities for moisture to damage the critical device. How will added moisture control affect our test results? Without sufficient moisture control, you risk build-up of condensation. For the engineer, this could mean inefficiencies in measurements or costly damage to the device. For the clinicians, this couldmean incorrect or slow measurements, downtime for device repair, and potentially retestingthe patient. The effects are costly and delay patient results and diagnosis. The reason respiratory engineers turn to Perma Pure is to mitigate risks of moisture issues with a customizedNafion™ Tubing solution. Nafion™ Tubing can be connected to your chosen sampling line or we can support yourteam in designing and manufacturing a unique sampling line for your device. The savings in cost and time to you, the technician using your device, and the patient in need of a diagnosis or assessment, makes Nafion™ Tubing a solid choice for moisture control. What could affect drying performance in my Nafion™ Tubing? Dehumidification performance can be diminished by a variety of factors. Given that PFT and CPET are performedunder a variety of conditions we can only share what we have learned. Since Nafion™ Tubing is used with PFT and CPET testing equipment, in environments where heavybreathing is needed, technicians may want to disinfect equipment in between patients. Our ME Dryers, made from Nafion™ Tubing, are…
Nafion™ is a polymer that can add/remove select materials, including water vapor, to a gas stream through a first order kinetic reaction (a chemical reaction). Because it’s non-porous, other molecules…
When designing medical equipment, engineers can often feel like Goldilocks when it comes to humidity: there’s too much or too little—and their challenge is to make it just right. Too…

Breath has lots of moisture. To see, just blow on a mirror and watch it fog up. Getting rid of the moisture on the mirror is easy: just wipe it…
When hearing terms like humidity and relative humidity, people often think about the weather. This is because water vapor has an impact on how humans perceive comfort; both high humidity…
We’ve all crinkled our noses when we’ve caught a whiff of wet clothes that sat in the clothes hamper too long. They smell bad. Our noses are warning us that…
Moisture matters. Just ask any runner who’s slogged through a steamy afternoon. The same can be said for medical professionals trying to analyze a person’s breath. Here’s what happens. Humidity…
