Breath Holding Time Results for Sick People: Low Body Oxygen
Medical and physiological research articles about BHT (breath holding time test done after usual exhalation and only until initial discomfort) or CP (Control Pause or Buteyko Control Pause - see the link to the test below), or body oxygen level in people with chronic diseases.
On the graph below, the numbers of patients are provided in brackets. For example, "Hypertension (95)" means that 95 hypertension patients were studied. The body-oxygen level (breath holding time) for all groups of sick people was measured in seconds.
Again as before, breath holding can be done in different conditions (e.g., after normal inhalation, or exhalation, or after taking a very deep inhalation, or after a complete exhalation, until first stress or as long as possible). However, in order to find body-oxygen levels in these sick people, it is logical to use normal conditions: usual exhalation (or at functional residual capacity = volume of air in the lungs at normal expiration) and stress-free version of the test (no pushing the patient for better numbers and no gasping after the test). If you are interested in these details, visit Body Oxygen Complete Table for Sick People and see how these different tests were standardized.
These Control Pause values or body-oxygen levels for sick people can be compared with Normal Breath Holding Time - Control Pause in Healthy People.
Doctor Buteyko and his MDs tested thousands of patients
and found that the following relationships, in general, hold true in relation to
1-10 s - severely sick, terminally and critically ill patients, usually hospitalized.
10-20 s - sick patients with numerous symptoms, complaints and, often, on daily medication.
20-40 s - people with poor health (no major symptoms), often without serious organic problems.
40-60 s - good or normal health.
Over 60 s - ideal health, when many chronic diseases are virtually impossible.
My own practical experience with hundreds of Buteyko students, who were previously sick or very sick, and other people completely agrees with these findings.
Conclusion: Sick people have low body-oxygen levels and shorter breath holding time results due to heavy breathing (see the Homepage for modern average breathing rates).
