Cancer: Heavy Breathing and DyspneaBy Dr. Artour Rakhimov - Last updated on August 9, 2018
Severe Cancer: 25-40 Breaths/Min
This video is about breathing in cancer and most effective known clinical trial on patients with metastatic cancer: Breathing and cancer.
What is the typical breathing frequency in cancer patients with dyspnea? US medical doctors from the Massey Cancer Center (Virginia Commonwealth University in Richmond, Virginia, USA) tested 35 cancer patients (of the 35 patients, 34 were using oxygen) and found that their average breathing rate was 28.4 breaths/minute (Coyne et al, 2002). A 1993 study done by Italian and Canadian doctors revealed the respiratory rate of around 23 breathes per minute (Bruera et al, 1993) in a group of terminal cancer patients with dyspnea. A Swiss study conducted in the Division of Palliative Care, University Hospital, Lausanne found about 26 breaths per minute in elderly patients with advanced cancer (Mazzocato et al, 1999).
In two recent German studies (Department of Anaesthesiology, Intensive Care Medicine, Bonn), average breathing rates in 2 groups of cancer patients were stunning 42 and 39 breaths per minute (Clemens et al, 2007; Clemens et al, 2008). It is indeed physiologically shocking numbers since the normal respiratory frequency is only 12 breaths per one minute. (Old medical textbooks suggest 8-10 breaths per minute as normal.)
As we found before, the respiratory rate for the normal breathing pattern for adults is only 12 breaths/min at rest, while Dr. Buteyko's norm is only 8 breaths per minute (see Parameters of Normal Breathing or Buteyko Table of Health Zones). here are respiratory rates in people with cancer.
We can see that cancer patients breathe much more than both norms. Furthermore, respiratory rate (breathing frequency) of cancer patients, as many studies have found, is an independent predictor of their mortality (Chiang et al, 2009; Groeger et al, 1998; de Miguel Sanchez et al, 2006). Those cancer sufferers, who breathe faster or more frequently, have higher mortality rates and poorer prognosis. This link (between slow spontaneous breathing and higher chances of survival) relates to all cancer patients, those with and without dyspnea.
Conclusion. Cancer patients: the faster they breathe, the sooner they die.
In 2008, the Journal of Applied Physiology published a study (Travers et al, 2008) from the Department of Medicine, Queen's University (Kingston, Canada). It was revealed that forty patients with cancer breathed around 12 liters of air per minute at rest, instead of 6 l/min (the medical norm). The average breathing frequency of these cancer patients was 20 breaths per minute (the norm is only 12 breaths per min at rest). Tidal volume of these cancer patients (600 ml of air per one breath) was also more than the norm (which is 500 ml). Hence, these cancer patients had both, fast and deep breathing, in comparison with the medical norms.
We also learned that normal breathing is invisible and inaudible since it is very slow in frequency and tiny in tidal volume. What about visual breathing parameters of cancer patients at rest? In other words, what do the doctors see? Heavy breathing and nearly gasping for air.
After this overwhelming testimony of medical clinical doctors, it is more than clear that terminal cancer patients have heavy breathing patterns. (As we are going to learn later, that causes severe cell hypoxia that causes devastating effects on the immune system due to free radicals and oxidative damage.)
But normal breathing, as we discussed, (see Homepage links) is invisible, inaudible, and imperceptible. Moreover, according to physiological laws, normal breathing provides humans with superior tissue oxygenation. Hence, healthy people do not feel their breath at all. These cancer patients breathe at least 3-4 times more than the norm in order to be uncomfortably aware about their breathing.
