PFT Machine for Pulmonologists

Why Pulmonologists Are Rethinking Traditional PFT Machines

Many pulmonologists today are reconsidering the role traditional pulmonary function testing (PFT) equipment plays in their practice. While legacy body box systems have been standard for decades, they come with hidden costs that affect clinical efficiency and the bottom line. These include large physical footprints, dedicated room requirements, extensive calibration, specialized technician staffing, and slower patient throughput.

More importantly, these systems often limit flexibility, making it harder to offer comprehensive testing in office settings. With growing patient volumes and tighter reimbursement models, pulmonologists are actively seeking smarter, space-saving alternatives that don’t compromise diagnostic quality.

We hear this a lot from pulmonologists we work with: the body box is fine when it works, but it’s the last thing they want to deal with when they’re running behind, have a patient who can’t fit comfortably in the cabin, or are trying to open a second location. That’s exactly the problem the MiniBox+ was built to solve.

A Better PFT Machine for Pulmonologists: Meet MiniBox+

The MiniBox+ from PulmOne is a modern solution designed specifically for the needs of pulmonary practices. It provides complete PFTs including spirometry, lung volumes, and DLCO in a compact, desktop unit that fits easily into any exam room. It requires no body cabin, no gas cylinders, and no complex calibration routines.

With its quick setup and intuitive interface, the MiniBox+ enables high-volume, high-quality lung function testing directly within your practice. This means fewer patient referrals, faster diagnosis, and improved continuity of care.

For pulmonologists specifically, having lung volumes and DLCO in-house changes how you manage patients. You’re not waiting on a referral report to confirm what you already suspected. You’re getting TLC, RV, FRC, and DLCO right there in your office, same visit, with results that meet the same clinical standards as a full pulmonary function lab. Patients with COPD, pulmonary fibrosis, or mixed obstructive-restrictive disease get a more complete picture faster, and you keep the diagnostic work where it belongs — in your practice.

MiniBox+ vs Traditional PFT Machines: What Pulmonologists Need to Know

Space Efficiency

Traditional systems require large, dedicated rooms. MiniBox+ is small enough to operate from any exam room, saving valuable space and reducing infrastructure overhead.

Ease of Use

Conventional PFT devices often require specialized technicians. The MiniBox+ is designed for general staff to operate with minimal training, using self-calibrating sensors and an intuitive interface.

Speed and Throughput

Full PFTs, including lung volume measurements, can be completed in under 20 minutes, allowing for more tests per day without sacrificing accuracy or patient experience.

Clinical Accuracy

Peer-reviewed studies have shown that the MiniBox+ delivers lung volume measurements equivalent to those from body plethysmography. You get confidence in results without the limitations of a cabin-based system.

Operational Costs

Beyond the purchase price, legacy systems introduce ongoing costs like room buildouts, service contracts, dedicated staff training, and revenue lost every time you refer a patient out for testing you could be doing yourself. We’ve had pulmonologists tell us they didn’t realize how much they were leaving on the table until they looked at a full year of referral data. MiniBox+ eliminates most of that overhead, and because it supports full reimbursement for lung volumes and DLCO, the ROI tends to come faster than practices expect.

Designed for Pulmonary Practices: Smarter Testing, Better Outcomes

PulmOne built the MiniBox+ with the needs of pulmonologists in mind. Whether you operate an outpatient clinic, hospital-based office, or multi-site network, MiniBox+ supports:

In-office testing without need for a lab
Improved patient comfort and compliance
Expanded access to lung volume and DLCO testing
Increased billing potential with more tests kept in-house
Reliable, repeatable results that meet ATS/ERS standards

That last point, “reliable, repeatable results”, matters more than it sounds. In pulmonology, you’re often tracking change over time. A patient with IPF coming in every six months, a post-transplant patient on close monitoring, someone on a biologic for severe asthma. You need to trust that the number you get today is comparable to the number from the last visit. The MiniBox+ delivers that consistency visit after visit, without the variability that can creep in with equipment that requires extensive technician-dependent calibration.
