Isocapnic Respiratory Training
Method or Modality Isocapnic respiratory training is a method of conditioning the respiratory muscles with the use of a carbon dioxide recapturing system. This CO2 recapturing system is usually done with a rebreather bag and some sort of regulator valve to properly mix inhaled and exhaled gases. It is more than just breathing into a bag; the mixture of gases inhaled and exhaled must be calibrated precisely so the user does not suffer the effects of hyperventilation or hypoventilation.[1]
Background The more your body moves, the more it uses oxygen and produces CO2. Once the lungs are working at their capacity, any further movement is limited. Most people only ever have the use of 65-70% of their lung capacity. This can be less than 50% for people with COPD/Asthma. When your respiratory system comes under stress, your autonomic system diverts resources to protect the respiratory system, metaboreflex[2] metaboreflex. This means your working muscles will be robbed of what they need to perform if your lungs are not conditioned to sustain the workload. [3] [4] [5] [6] [7] [8] [9] [10]
