Something has changed at Vitamin Institute Munich over the past few weeks: for Interval Hypoxic-Hyperoxic Training (IHHT), we are now using the CellAir Pro from German manufacturer CellGym – a professional, next-generation system. This isn’t just a routine upgrade: it’s a direct response to growing demand for IHHT at our practice, and to our own standard of making every session as precise and as safe as medically possible. In this article, we explain why we invested, how the new technology actually works, what changes for your treatment, and what the scientific evidence on IHHT safety really says.
Key Takeaways:
- Vitamin Institute Munich now treats patients with the CellAir Pro by CellGym.
- The patent-pending OAPC technology automatically stabilises the hypoxic stimulus – even as air pressure or weather change.
- The Hypoxic Session Index (HSI®) makes your training progress visible and documentable in real time.
- Redundant 1oo2 sensor monitoring and predictive maintenance increase safety during every session.
- An independent 2021 meta-analysis confirms: no serious adverse events from intermittent hypoxia conditioning in cardiology studies.
- The process and session length (20–45 minutes) remain unchanged for you.

Why Is a Munich Practice Investing in a New IHHT Device Now?
Demand for IHHT at our practice has grown continuously over the past few years – whether for chronic exhaustion, support after Long COVID, more restorative sleep, or as part of a longevity programme. With growing demand comes growing responsibility: the longer and more individualised a treatment cycle is, the more important it becomes that every single session is reproducible and precisely dosed – regardless of whether a storm is raging outside or a high-pressure system sits over Munich, since air-pressure fluctuations can measurably affect the breathing-air composition delivered by older IHHT systems.
This is exactly where the CellAir Pro comes in: it is built for professional, continuous use in medical practices and longevity centres, and it bundles more than 15 years of development experience from manufacturer CellGym, which by its own account supports more than 3,800 practice and studio partners worldwide and has accompanied over 12.5 million documented IHHT applications (cellgym.de, as of July 2026). For us as a medical practice, what mattered was that the new device generation works not just more comfortably, but measurably more controlled than classical IHHT systems.
What Is OAPC Technology – and What Does It Mean for You?
The technical core of the CellAir Pro is its patent-pending OAPC technology. Older IHHT devices mix breathing air according to a fixed programme – regardless of how external conditions such as air pressure or humidity are changing in real time. The CellAir Pro instead measures these conditions continuously and automatically readjusts the oxygen concentration, so that the hypoxic stimulus stays constant throughout a session – and across multiple sessions.
For you as a patient, this means one thing above all: if you go through a course of 10 to 15 sessions, each individual session is genuinely comparable to the last. That’s not cosmetic, it’s medically relevant – because the therapeutic effect of IHHT relies precisely on repeated, dosed stress on the mitochondria, and that dose can only be judged if it was actually kept constant. The oxygen range continues to span hypoxia (9–20%) through normoxia (20.9%) to hyperoxia (22–34%); a session still lasts 20 to 45 minutes.
How Does the Hypoxic Session Index (HSI®) Work?
The second major innovation is the Hypoxic Session Index (HSI®). According to the manufacturer, it bundles more than 15 years of CellGym experience into a real-time analysis of your response to each session – based on factors including oxygen saturation and pulse trajectory. The result is a traceable, documentable read-out of how your body responds to the therapy, rather than a purely subjective impression.
In practice, we use the HSI in two ways: first, to adjust the protocol during an ongoing course if needed – for example if it becomes clear you’re responding faster or slower than average. Second, to give you honest feedback on your own progress, rather than relying solely on how you feel. Heart rate variability (HRV) can optionally be recorded as well, which provides additional information particularly for stress- and exhaustion-related conditions.
In addition, redundant 1oo2 sensor technology – two independent sensors per measured value – continuously monitors the session; if one sensor deviates from the other, it is flagged immediately rather than only being noticed afterwards. The device’s predictive maintenance system also flags service needs before they can cause a failure during an ongoing treatment.
What Actually Changes for You as a Patient in Munich?
The outward process of your treatment stays the same: an initial consultation, individual goal-setting, and sessions of 20 to 45 minutes in a relaxed reclined position while you breathe controlled air through a mask. What’s new is the quality behind it:
- More consistent results across an entire treatment course, thanks to OAPC technology.
- Visible, documented progress via the HSI, which we discuss with you.
- More safety through redundant sensor monitoring that flags deviations immediately.
Nothing changes about our existing pricing and packages as a result of this upgrade – we’re happy to discuss the details of process and cost for IHHT treatment at Vitamin Institute with you personally, since these vary by individual treatment goal.
Who Benefits Most From IHHT With the New Device?
In our practice, we see four patient groups in particular for whom a session with the new CellAir Pro is especially worthwhile.
If you struggle with persistent exhaustion and feel like you’re not really recovering despite adequate sleep, you often benefit from targeted mitochondrial stress – more on this in our article on mitochondrial training for chronic exhaustion. We also use IHHT as supportive therapy after a COVID-19 infection with lingering symptoms; we’ve summarised our experience in our article on IHHT therapy for Long COVID.
If you struggle with sleep problems or an overactivated nervous system, our article on IHHT and nervous system reset has more background – the CellAir Pro’s added precision matters especially here, because a constant stimulus is more important for a calming nervous system than a strong but irregular one. And if you want to use IHHT preventively as part of a longevity programme, you’ll find further information in our article on the 2026 IHHT trend.
For a detailed comparison between IHHT and classical altitude training – including why a reclined, medically supervised session produces different effects than athletic altitude training – see this article.
How Safe Is IHHT? What the Scientific Evidence Says
Alongside the device technology itself, the question of scientific grounding matters just as much to us as a medical practice. A 2021 systematic review and meta-analysis published in Current Cardiology Reviews by Glazachev and colleagues evaluated multiple controlled studies on intermittent hypoxia conditioning in patients with cardiovascular disease. The analysis found significant reductions in resting heart rate (mean −5.35 beats/minute) as well as systolic (−13.72 mmHg) and diastolic blood pressure (−7.88 mmHg) after treatment – with no serious adverse events related to the therapy (Glazachev et al., 2021).
That doesn’t mean IHHT is suitable for everyone or that blanket promises are warranted – as with any medical intervention, we assess contraindications individually during the initial consultation. But it does mean that the foundation on which we operate the new CellAir Pro rests not only on manufacturer claims, but on independent research as well.
