During the time of his research, Carl heard about cinefluorographic films (x-ray movies that were being used at the time to study the workings of internal organs). He requested that they be made of his patients' diaphragms, so that he could study them. These films showed the soap bubblyish, fluttering, diffused structure of the emphysemateous diaphragm, barely able to move. This was in contrast to the films of his own diaphragm which showed a healthy firm structure, able to move upward inside of his ribcage on the exhale 12 centimeters (a little over five inches). Encouraged by the cinefluorographic films that were taken before and after his work, Carl forged ahead in the development of his exercises. They were simple, requiring only that his patient relax and count out loud and silently, as he gently palpated the muscles of the neck, throat, root of the tongue, jaw, shoulders, chest, back and abdomen reducing the residual volume and thereby repositioning the chest, lowering the ribcage and bringing the patient back to a normal way of breathing.

Carl's incredible ability to visualize, keen ear for sound, heightened sense of touch and highly developed instincts were what enabled him to make the discovery he called, BREATHING COORDINATION. Through the years, BREATHING COORDINATION enabled hundreds of patients with asthma, allergies, bonchitis, bronchiectasis, emphysema, brain damage, cerebral palsy, mutiple sclerosis, shingles, cancer encephalitis, paralysis, achalasia, esophageal hernia, osteoporosis, arthritis, anxiety, emotional problems, stress, tension, chronic fatigue, migraine headaches, respiratory faults, parkinson's disease, myasthenia gravis, coronary problems, atrial fibrilation, arrythmia, vocal disorders such as stuttering, spastric dysphonia, nodes, aphasia, voice projection problems, singing disorders, scoliosis, kyphosis and back pain to improve their health. The medical doctors at West Haven Veteran's Administration Hospital, the largest out patient pulmonary facility on the East Coast, eventually conceded that the only reason Carl had been able to make his discovery was because he was not limited by the preconceived ideas learned in medical training.

In 1968 The American Olympic Team heard about Carl's work and called on him to train athletes in preparation for the high altitude Mexican Games. In a letter to Carl after the 1968 Olympic victories, Payton Jordan, head coach of the U.S. Olympic Track and Field Team writes " I want to express in writing my eternal gratitude for….your expert breathing coordination instruction for the athletes. You…were instrumental in creating the finest spirit ever and MORE WORLD AND OLYMPIC RECORDS THAN IN ALL PAST GAMES HISTOY!" These records would stand for over 25 years and our track and field team would be the only team to not require oxygen.

Most of us do not think about our breathing until we start to have problems with it. These problems all stem from unconscious breath holding and forced breathing. In order to be able to let go of these habits, we must first understand how the respiratory system works, especially the most important muscle/organ of respiration-THE DIAPHRAGM.
