K²O₂. The methodology behind Cellular Surprise.

The method structures intermittent oxygen training protocols around controlled change and recovery.

From lower oxygen to normal air — and back

Without going anywhere.

Periods of lower-oxygen breathing air alternate with normal-oxygen recovery while you remain at rest.

Cellular Surprise

The controlled changes are intended to create a brief physiological training stimulus.

Home includes Karim’s signature protocols. Pro adds personalized protocols through a proprietary questionnaire and algorithm.

Adaptation

The response is the training.

Precisely timed oxygen changes are intended to engage natural adaptive responses. Research on specific protocols cannot guarantee an individual result.

The training stimulus is distinct from the restful setting in which the session takes place.

The training. The setting. The Breathing Lounge.

An immersive setting designed for deep rest.

Music, darkness, gentle vibration and weighted comfort shape the experience in a home or professional space.

The device and Lounge elements are supplied separately unless quoted together.

Your system. Our guidance.

Tell us whether you are considering Home or Pro and where you intend to use it. A personal conversation helps clarify the model, your intended routine and which configuration or support options to explore.

We can discuss the price, equipment and accessories, setup, training, optional Breathing Lounge elements and any ongoing services. A quotation clarifies the applicable details. Sending an enquiry does not place an order.

Karim Chubin

Karim Chubin
Founder, Anthropologist,
Naturopath, Explorer

After COVID affected my lungs and left me depleted, I began looking for a way back. That search led me to intermittent oxygen training.

As a naturopath and anthropologist, I became interested in how training, adaptation and rest could come together in one experience.

I developed K²O₂ as my proprietary approach to training protocols.

Cellular Surprise brings that work into Home and Pro systems. The Breathing Lounge adds an immersive setting around the training.

My aim is to help individuals and professional practices choose the right configuration and understand the support available.

Signature protocols. In your own space.

Home brings Karim Chubin’s built-in signature programmes into a guided private training routine. Sessions take place while you rest.

A routine planned around your goals.

Session duration and frequency are not the same for everyone. Your physical condition and training goals are relevant when planning a routine; discuss these alongside your home setup before getting started.

Settle into a comfortable resting position, place the breathing mask and follow the selected programme. The device guides the protocol while you rest.

Simple guided control.

Pre-installed automatic programmes are controlled by tablet. Before you order, we’ll review dimensions, weight, power and operating conditions and confirm setup requirements for your space.

Plan the system for your space.

Tell us about your intended setup and the help you may need getting started. A consultation can clarify the selected configuration, accessories, setup requirements, training and support. Your quotation identifies what is included and what remains optional.

The Breathing Lounge is separate.

Music, vibration, weighted comfort and furnishings are optional elements of the surrounding experience. They are not part of the device offer unless your quotation specifically includes them.

Your questions

You alternate between periods of lower-oxygen air and normal-oxygen recovery while resting.

No. You recline and breathe through a mask throughout the session.

There is no single schedule for everyone. Session duration and frequency depend on your physical condition and training goals.

Home offers guided access to Karim’s signature protocols. The surrounding experience can be shaped around your preferences, environment and routine.

The device is the training system. Music, vibration, weighted comfort and other furnishings are separate unless your quote says they are included.

Tell us about your intended space and routine. We can review the available configuration, pricing, setup and support in a personal consultation. Your quotation clarifies what is included; sending an enquiry does not place an order.

Cellular Surprise Pro

Cellular Surprise Pro

Personalized protocols. Remote connection.

Pro combines person-specific training protocols with connected support options. It is available for professional settings and individual ownership, subject to the selected configuration.

Request pricing

What Pro adds beyond built-in programmes.

Where Home provides signature training programmes, Pro introduces a person-specific starting point. This distinction matters when the training approach needs to be shaped around an individual rather than selected from guided programmes.

Karim’s proprietary questionnaire supplies the inputs for his algorithm to generate a person-specific training protocol.

The questionnaire, algorithm and protocol details remain proprietary; discuss how the process fits your use during a consultation.

Connected support, with defined scope.

Remote monitoring and control can support a professional practice or an individual user, subject to the supplied configuration and connection.

We can clarify what can be viewed or adjusted, who can access it and whether an ongoing service charge applies.

Plan the working setup.

Consider who will operate the system, where it will be installed and which connection or remote-support options matter in your setting. Available capabilities depend on the selected configuration.

Clarify the offer before you decide.

A personal consultation can cover the configuration, onboarding, user or team training, protocol guidance, technical support and any recurring services. Your quotation specifies the applicable terms.

Any Breathing Lounge furnishings or accessories are separate unless included in the quotation.

Your questions

Home includes Karim’s signature protocols. Pro adds a personalized protocol generated through Karim’s proprietary questionnaire and algorithm, together with remote monitoring and control.

Clinics, health and rehabilitation practices, performance facilities, wellness providers and individual users seeking a personalized protocol and connected support.

Yes. Contact us to discuss research relevant to your practice and interests. Research on other devices or protocols does not establish an individual outcome for Cellular Surprise.

We can discuss your intended setting, the personalization process, setup, team or individual training, remote-service availability and any ongoing costs. Your quotation will clarify what applies to the selected configuration.
