“As a retired physician, having specialized in medically unexplained symptoms for many years, I found that the end-tidal measurement of carbon dioxide in the breath was an essential component to successful work with people suffering from these kinds of symptoms. During my clinical work using the CapnoTrainer, I saw many people recover their physiological resilience and lose symptoms that had been present for many years. Clients work through breathing practicums programmed into the CapnoTrainer software, which allows them to auto-adjust their breathing style when challenged by stress or retained trauma. The CapnoTrainer helps clients learn to self-calm, self-regulate, and successfully overcome symptoms often making what was unexplainable explainable.”

“My accidental exposure to capnometry and hypocapnia 20 years ago changed my practice of physical therapy forever and improved my effectiveness with all types of patients. Since that time, I have been pioneering the use of CapnoTrainers in my busy outpatient orthopedic private practice. In-house practice-based research indicated 66% of 100 consecutive patients entering the clinic have some level of hypocapnia. My study of the breathing sciences and the associated behavioral physiology through the Professional School of Behavioral Health Sciences has transformed my approach to all patients, especially those in chronic pain as well as sports performance. Our testing and treatment protocols utilizing the CapnoTrainer are now an integral part of our practice with every type of diagnosis we see. I am very grateful to bring this unique and effective treatment to our patients and the practice of Physical Therapy.”

“Understanding breathing as behavior and how breathing habits impact my clients was a major game-changer. As a breathing science nerd, I see the teachings of breathing psychophysiology as fundamental to optimizing the outcomes of my professional work. CapnoTrainer technology and its learning applications make possible guiding my clients quickly and effectively toward disengaging bad breathing habits that compromise performance and acquiring new ones that optimize respiration for improving health and performance.”

“I am a registered maternal and mental health professional in Canada. In 2015 I was told I would be on permanent disability as a result of residual symptoms from a car accident. I found Better Physiology Ltd through a teacher at a "breathwork" class and learned about how a Capnotrainer might help me change breathing habits that could have been blocking my full recovery. Within six months I was fully recovered; I learned to disengage breathing habits that were compromising my respiration, thus allowing my body to heal itself on its own. Since then, I have completed a master’s degree in applied Breathing Sciences which has completely revolutionized my professional practice. All of my clients have access to breathing behavior analysis services and a CapnoTrainer where together we create breathing behavior learning plans for learning new habits that optimize respiration. The quality of the CapnoTrainer technology along with the amazing software applications make breathing behavior analysis accessible to professionals who want to integrate real breathing science into their practices. Together the new book on CapnoLearning (Litchfield & Reamer, 2023) and the online training built into the software make learning on your own not only possible but immensely self-empowering.”

“CapnoLearning® with CapnoTrainer® GO instrumentation brings together physiology, psychology, and technology to create powerful tools for identifying good and bad breathing habits, for learning to disengage habits that compromise physical and mental competence, and for learning new breathing habits that promote health and performance. Understanding breathing as behavior makes these objectives possible through implementing the principles and applications of breathing behavior analysis. The CapnoTrainer® GO is a learning tool for a wide range of educated audiences interested in breathing science and its professional and personal applications. (Litchfield and Reamer, 2023) People everywhere use breathing techniques for meeting personal and professional objectives but are rarely informed as to the fundamentals of breathing physiology and psychology. The consequence is misguided breathing practices, misinformed practitioners, and a prevailing popular pseudoscience. (Litchfield and Reamer, 2023) The CapnoTrainer GO® addresses this shortcoming dead center.”

“By way of introduction, my name is Dylan McKay, and I am the co-founder of RenderSafe, a pioneering Explosive Ordnance Disposal (EOD) company revolutionising Advanced EOD training and capability development for the Defence and Security industry. I also served for over a decade as a Commissioned Officer in the New Zealand Army, the majority of which I served as an EOD Commander in the NZ Special Forces (NZSAS). I have experienced first-hand the critical importance of evidence-driven strategies for optimising human performance in high-stakes environments during multiple operational deployments and whilst leading the NZ Special Forces Human Performance Programme (HPP) between 2017 – 2021. Leading a team of specialised professionals, our mission was to enhance the durability, longevity, and health of the unit’s personnel, reduce injuries, and optimise human performance. I was introduced to Dr Peter Litchfield by a mutual colleague in 2019 and after recognising the profound impact and value that his work held for our people, a few team members and I completed Dr Litchfield’s entry certificate programme, called the Science of Breathing Behaviour Analysis. After completing the course a number of our team, including myself, went on to become Certified Breathing Behavioural Analysts and we also established a “battle-lab” so that we could experiment with the implementation of new technologies such as the CapnoTrainer. An aspect of performance and health that was investigated during the battlelab, was the application of breathing behavioral analysis and modification (CapnoLearning), both to mitigate stressors and promote optimal performance. Data obtained suggests that improving breathing behaviours in SOF Operators can result in rapid and significant performance improvements, demonstrated by improved scores in physical tests, enhanced focus, and cognition during “shoot, move, communicate, decide” scenarios, reduced risk of injury and improved passing rates for SOF selection courses. I have now integrated the use of the CapnoTrainer GO and Go-Pro cameras in our training courses at RenderSafe to enhance the learning outcomes for participants. The system is lightweight and small enough to fit in a standard pouch and the nasal cannula can be worn without interfering with personal protection equipment such as eyewear, helmet, and face masks. The physiological data collected from the CapnoTrainer GO, in conjunction with video footage, combined with the individuals subjective reporting empowers participants to recognise how their psycho-physiological responses effect cognition and performance during training tasks. The intent is to provide participants with greater self-awareness of the impact of their own learned breathing behaviours on performance, and then, using CapnoLearning principles, develop their ability for self-regulation which is critical for them to deal with the complex, stressful, and lethal situations they will encounter during crisis response. The CapnoTrainer GO can help the SOF Operator to recognise and understand their own individual breathing responses to stressors. Recognising these responses (breathing behaviours) is the first step in an individual’s ability to self-regulate, providing them access to critical cognitive abilities and skillsets they need to perform under extremis circumstances. Unfortunately, this fact is normally overlooked in training delivery. This is why we use the CapnoTrainer GO during training serials that replicate high risk, non-permissive environments then we can systematically increase exposure to more complex training scenarios by using stress inoculation techniques while simultaneously working with each participant to understand how they are responding psycho-physiologically. As someone deeply invested in health and peak performance, I cannot speak highly enough about the CapnoTrainer GO. This innovative instrument seamlessly integrates hardware and software, offering a transformative approach to breathing education and behavioral analysis. With its intuitive interface and personalised training tools, the CapnoTrainer GO has revolutionised the way we understand and manage individuals breathing behaviour. Through live physiology feedback and recorded data analysis, you will gain invaluable insights into your respiratory habits, enabling you to optimise your breathing for enhanced focus, relaxation, performance, and well-being. Whether you’re a military operator or athlete striving for peak performance, a professional seeking stress management techniques, or simply someone committed to living a healthier life, the CapnoTrainer GO is a game-changer. It empowers you to learn about your breathing with precision and confidence, unlocking your full potential one breath at a time.”

“Wearable capnography might be the single most significant revolution in optimizing physiological and psychological performance and resilience. I will tell you why but must share with whom this has been tested. Across 35 years, as a psychologist and scientist, I have been responsible for designing agency-wide human performance and resilience programs for military Special Operations Forces, Federal Law Enforcement, and the Intelligence Community, for well over 100,000 personnel. What is human performance and resilience? High-frequency, high-consequence missions require biofeedback to optimize cognitive, socio-emotional, and physical skills, and reduce the adverse impacts of continuously performing at an elite level. In-between, we must quickly restore the ability to joyfully recreate with our friends, to be fully present with our beloved families, and to be peacefully at ease within ourselves. Extreme stress can cannibalize the careers, wellbeing, and the lives of the Force and their Families. What can both optimize cognitive and physical performance and reduce the adverse impacts of a life of service? I research, develop, test, and evaluate the least disruptive, easiest interpretation, simplest user experience of one’s capacity and baseline readiness. Performance and resilience biofeedback has reached a pinnacle in Better Physiology’s CapnoTrainer GO: wireless, silent, vibration-free, miniature, near real-time monitoring of one’s mental and physical state, in an easy to interpret graphical interface that allows you to identify the precise individualized skill or intervention, that re-regulates and marshals all of your mental and physical resources. With little study and time, the quick-start up, and rapid technical service for questions, will empower you with biofeedback more immediate than heart rate variability, heart rate, brain wave, skin conductance, or muscle tension, and yet each (HRV, ECG, EEG, EDA, EMG) can be integrated into it as a sensor suite. Nothing is more instantly controllable and more systemically impactful than breathing biofeedback which the CapnoTrainer Go revolutionizes. As a gold medalist for the U.S. National Team, I have strived for this in my own life, despite injuries and over training, but more importantly, to address my own learning disabilities, and the stress of my own career, and the normal day-to-day challenges of living a life of bills, parenting, aging, pains, and worries. So, I selfishly use wearable capnography to enjoy the fruits of life well-lived while maintaining my own peaceful, playful moments with my friends and family. For your own optimization and wellbeing, or to enable them in those you serve and support as a counselor, therapist, researcher, psychologist, physician, nurse, coach, trainer, chaplain, or non-healthcare professional, the CapnoTrainer Go is the best investment your funding you could make.”
