Capno Trainer 1 Capno Trainer  Capno Trainer 2

A unique learning instrument with paper trail capability of training and monitoring a patient client's breathing and MUCH MORE. I have used this for over 10 years. Dr. Litchfield has done a masterful job creating an easy to use, an ultra-sensitive instrument with over 10 million dollars worth of software. It is often indispensable. Anyone from biofeedback therapists to yoga classes or schools can use this incredible technology.

Capnometer & Capnometry 

Assessing for and training to achieve optimal blood oxygen. We use this it to expose and measure an intensity of obvious or hidden hyperventilation.  We use it in conjunction with our many other breathing assessment factors partly listed at consulting before and after our breathing development sessions for another measure of progress.

Did you know that over-breathing (CO2 deficiency) can trigger or exacerbate physical and psychological complaints such as: 
shortness of breath, breathlessness, chest tightness & pressure, chest pain, feelings of suffocation, sweaty palms, cold hands, tingling of the skin, numbness, heart palpitations, irregular heartbeat, anxiety, apprehension, emotional outbursts, stress, tenseness, fatigue, weakness, exhaustion, dry mouth, nausea, light-headedness, dizziness, fainting, black-out, blurred vision, confusion, disorientation, attention deficit, poor thinking, poor memory, poor concentration, impaired judgment, problem solving deficit, reduced pain threshold, headache, trembling, twitching, shivering, muscle tension, spasm, stiffness, abdominal cramps and bloatedness.

Did you know that in predisposed individuals, over-breathing (CO2 deficiency) may trigger or exacerbate: 
phobias (e.g., public speaking), migraine phenomena, hypertension, attention disorder, asthma attacks, angina attacks, heart attacks, panic attacks, hypoglycemia, ischemia (e.g., brain cell death), depression, epileptic seizures, sexual dysfunction, sleep disturbances, allergy, irritable bowel syndrome, repetitive strain injury, and chronic fatigue.

If you are a trainer or a self-management coach, the Trainer may be an important adjunctive tool for: peak performance training, relaxation training, attention and & concentration training, alertness training, breathing training of any kind, meditation training, patient education, stress management,
