Nov 25, 2025 The Hidden Costs of Traditional PFT Equipment
Pulmonary function testing (PFT) is a cornerstone of respiratory care, especially for allergists, pulmonologists, and clinical directors managing asthma and related conditions. While the clinical value of PFT is well established, the true cost of PFT equipment often goes unexamined.
If you’re currently using or considering traditional spirometry labs or body box systems, it’s important to take a closer look. The purchase price of legacy PFT machines may be just the beginning. What’s often overlooked are the hidden costs, those that show up in lost time, staff inefficiencies, patient no-shows, and limited throughput.
This article explores the real price of maintaining outdated testing systems, reveals where your practice may be losing money, and shows how portable in-office pulmonary testing solutions like MiniBox+ can transform the economics of respiratory diagnostics.
The Real Price of Traditional PFT Systems
At first glance, traditional pulmonary function testing systems such as body plethysmographs can seem like long-term investments. But the true cost includes much more than the initial equipment purchase:
- Dedicated lab space and specialized HVAC requirements
- Ongoing calibration and service contracts
- Highly trained staff to operate and interpret results
- Longer test times, which limit the number of patients tested each day
- Referral leakage when patients must go off-site for full-function testing
These factors significantly impact the cost of traditional spirometry equipment in ways that are not reflected in your upfront investment. For outpatient clinics or small practices, these limitations can restrict growth and reduce efficiency.
Hidden Costs You Might Be Overlooking
Here are some of the most common hidden costs of PFT machines that practices may not be fully accounting for:
1. Loss of Staff Productivity
Every minute your staff spends setting up, calibrating, or troubleshooting traditional equipment is time not spent delivering care. In a PulmOne study, the main cost savings per test with MiniBox+ came from improved staff productivity. Clinicians and support teams can stay focused on patients, not equipment management.
2. Space and Facility Constraints
Legacy PFT machines often require dedicated rooms with specific ventilation and structural support. That is valuable space that could be used for additional exam rooms or other services. A portable lung function test device like MiniBox+ operates easily from a standard exam room.
3. Referral Loss and Delayed Care
Referring patients to external labs for comprehensive testing slows down diagnosis, adds administrative overhead, and reduces practice revenue. Some patients may not complete their testing, leading to care delays and missed opportunities for intervention.
4. Low Testing Throughput
Longer setup times and complex protocols reduce how many patients can be tested each day. This creates a bottleneck in clinical workflows. Portable systems allow for quicker tests and greater throughput without sacrificing accuracy.
5. Patient Noncompliance
Claustrophobic testing environments and long procedures can result in incomplete or failed tests. The open design of MiniBox+ is more comfortable and accessible, which helps increase test completion and improve diagnostic confidence.
Why Many Practices Are Re-Evaluating Their Approach
Allergy and immunology clinics are seeing more cases of asthma and chronic respiratory conditions than ever before. Many still rely on limited in-office spirometry or send patients to outside labs for complete testing. As patient volume grows, so does the strain of inefficient systems.
When you consider:
- Lost time due to external referrals
- Delays in diagnosis and care
- Limited access to full lung volume and DLCO measurements
- Room and staff constraints
It becomes clear why more clinical leaders are choosing to upgrade pulmonary testing. A modern solution not only reduces costs but also improves the quality and speed of care.
What to Do Instead: A Simpler, Smarter PFT Solution
PulmOne’s MiniBox+ is a compact desktop unit that delivers complete PFT results, including spirometry, lung volumes, and DLCO. It is built specifically for in-office pulmonary testing, with no gas tanks, no enclosed cabin, and no dedicated lab space required.
- This solution offers:
- Space-saving design that works in any standard exam room
- Easy operation, even by non-specialist staff
- Fast testing times, typically under 20 minutes
- Clinical accuracy backed by peer-reviewed research
MiniBox+ is the ideal asthma testing device for clinics looking to reduce referrals, speed up diagnoses, and retain more services in-house while delivering a better patient experience.
Making the Transition: What to Expect
Switching from a traditional PFT lab to an in-office solution might seem daunting, but the process is straightforward. Practices that adopt MiniBox+ experience:
- Quick and simple installation with minimal facility requirements
- Short training time for staff, thanks to an intuitive interface
- Seamless integration into daily workflow using standard CPT codes

- Fast return on investment, often within the first few months
PulmOne provides full onboarding, training, and ongoing support to ensure your clinic sees the benefits quickly and consistently.
Stop Letting Outdated PFT Equipment Hold You Back
If you are relying on traditional spirometry equipment or sending patients out for full pulmonary function tests, now is the time to reconsider. The cost of PFT equipment includes more than the upfront expense. It includes time, space, staff resources, and lost opportunities.
Upgrading to a portable PFT system like MiniBox+ offers real-world savings, increased diagnostic control, and a better experience for patients and staff alike.
