For a prescribing physician, the modern medical device market is often a paradox of choice. While the pace of innovation in respiratory and diabetes care has never been faster, the sheer volume of available technology can build it difficult to determine which specific device will actually perform for a specific patient. A device that meets all regulatory standards on paper may still fail to align with the unique physiological needs of a patient struggling with obstructive sleep apnea or brittle diabetes.
This gap between industrial standardization and clinical reality is where the concept of medical devices: a unique laboratory to test their characteristics becomes essential. Rather than relying solely on manufacturer specifications—which are designed to prove a device is safe and functional—some healthcare leaders are moving toward independent, simulated physiological testing to see how these devices behave in the messy, unpredictable environment of the human body.
Air Liquide Healthcare has addressed this challenge through the creation of Explor!, an autonomous scientific center dedicated to the rigorous assessment of devices used in home-based respiratory and diabetes therapies. By acting as a bridge between the innovation of manufacturers and the practicalities of home care, the center provides healthcare professionals with objective, reproducible data to move beyond general guidelines and toward truly personalized medicine.
The necessity for such a facility stems from a fundamental truth in medical engineering: meeting a technical specification is the baseline, not the goal. Most medical devices are required to meet strict, standardized specifications to receive regulatory approval. However, those standards often test devices in isolation or under idealized conditions. Explor! takes a complementary approach, developing proprietary tests that mimic the human body to measure performance under simulated physiological conditions.
Simulating the Human Body in the Lab
To achieve this, Explor! employs a multidisciplinary team of PhD researchers, engineers, and technicians who manage the entire scientific value chain. This includes the invention of custom test benches designed to replicate complex biological processes. For instance, in respiratory care, the lab utilizes advanced passive and active lung simulators. These artificial lungs allow researchers to measure how a device pushes air and how it affects the amplitude of inhalation and exhalation across various pathologies.
This level of simulation is critical because it allows clinicians to understand how a device’s internal algorithms respond to specific breathing patterns. In the field of sleep apnea, for example, the lab analyzes the ability of algorithms to accurately detect and classify hypopneas and apneas, distinguishing between central and obstructive events. They test pressure stability—ensuring that a device delivers the prescribed pressure even when air leaks are present, a common occurrence in home-care settings.
The lab’s scope extends beyond breathing to the complexities of metabolic health. In diabetes management, the center evaluates insulin pumps and continuous glucose monitoring (CGM) devices. By simulating fluctuating glycemic profiles, the lab can test the speed and reliability of a CGM’s accuracy, particularly during extreme cases of hypoglycemia and hyperglycemia where precise data is a matter of immediate patient safety.
| Evaluation Feature | Standard Manufacturer Testing | Explor! Scientific Assessment |
|---|---|---|
| Primary Goal | Regulatory compliance and safety | Clinical performance and patient matching |
| Testing Environment | Standardized, controlled specs | Simulated physiological conditions |
| Data Focus | Technical specifications | Behavioral response to patient profiles |
| Output | Certification/User Manuals | Peer-reviewed evidence/Comparative data |
From Technical Data to Clinical Knowledge
The objective of the Explor! laboratory is not to replace manufacturer data, but to transform that data into actionable clinical knowledge. With more than Air Liquide Healthcare’s commitment to value-based care, the center utilizes 15 proprietary testing protocols to compare devices side-by-side. This comparative approach allows physicians to see not just if a device works, but which device works better for a specific patient profile.
The impact of this data is most evident in treatment adherence. When a patient receives a device that is poorly matched to their physiology—perhaps a ventilator that fights their natural breathing rhythm or a CGM that lags during rapid glucose drops—they are far more likely to abandon the therapy. By selecting a device based on objective performance data, physicians can improve the patient experience and, the clinical outcome.
By sharing our scientific data, we enable doctors to proceed beyond standard guidelines, helping them to ensure that each device is best suited to their patient’s unique profile
This commitment to evidence is reflected in the lab’s output. To date, the center has conducted more than 50 device evaluations per year and has contributed to over 20 peer-reviewed scientific publications. By collaborating with academic laboratories and fostering PhD programs, the center ensures its findings are validated by the broader scientific community and shared constructively with manufacturers to drive further innovation.
The Broader Impact on Home Healthcare
The existence of such a laboratory signals a shift in the home healthcare landscape. For years, the “last mile” of care—the transition from the hospital to the home—was often a blind spot in terms of technical optimization. By integrating a dedicated laboratory into the home healthcare provider model, the focus shifts from simply delivering a piece of equipment to delivering a validated therapeutic solution.
This approach also makes disruptive innovations more accessible. As emerging technologies enter the market, the Explor! lab can quickly vet their real-world utility, providing healthcare professionals with the confidence to adopt cutting-edge tools that have been proven to work under simulated human conditions.

As the industry moves toward more integrated digital health solutions, the next phase of this scientific evolution will likely involve integrating real-world patient data back into these laboratory simulations. This feedback loop will allow for even more precise “digital twins” of patient physiology, further refining the process of matching the right technology to the right person.
