"...Death consists of the passing out of the air. It is, therefore,
necessary to restrain the breath."
Hatha Yoga Pradipika, (15th century)
is a normal clinical finding that with approaching death, breathing becomes
faster and deeper, while oxygen levels in the brain and other cells becomes
lower and lower. Separate web pages on this website have medical references that confirmed
very high respiratory rates (labored breathing) in terminal cancer, last stages of HIV-AIDS, cystic
fibrosis, and other conditions. (By the way, in the 1950's, observations of
breathing patterns in dying hospital patients led to the discovery of the
Buteyko breathing method: slow down your heavy breathing back to the medical
Many studies commented about and measured effects of
heavy breathing on health states of different groups of patients.
For example, 29 patients with severe liver damage (in most cases due to
deadly metastatic cancer or cirrhosis of liver) all had low arterial carbon dioxide, while for 25
patients "it was also clinically evident that respiratory exchange was
increased markedly" (p.762, Wanamee et al, 1956).
Thus, hyperventilation or
heavy breathing was visually observed by the authors of this publication,
Respiratory alkalosis in hepatic coma. They also found
that very heavy labored breathing led to severe electrolyte abnormalities.
These abnormalities included decreased sodium ions and increased
chloride ions in the blood. Abnormally high lactic and pyruvic acid
concentrations were other frequent effects.
Blood gases and respiratory patterns provided accurate
information for survival prognosis in acute cerebrovascular accidents.
When these parameters were normal, patients survived. Out of 11
hyperventilating patients with less than 35 mm Hg aCO2 (arterial carbon dioxide), only one
survived (Rout et al, 1971).
The same conclusion (regarding aCO2 and survival prognosis)
was made for head injuries (Huang et al, 1963; Vapalanti &
Death and heavy breathing
Summarizing the results of these works and their connection
with brain dysfunction, Dr. Plum wrote,
"The combination of hyperpnoea [increased breathing]
with an elevated pH, and a subnormal or moderately low oxygen tension
occurs in many serious illnesses that entirely spare the brain. These
include the alveolar-capillary block of diffuse pulmonary
carcinomatosis; heart failure; advanced cirrhosis, with or without
hepatic coma; acute pulmonary infarction; and many others, including
the cryptic pulmonary congestion that accompanies most serious disease
in the obtunded and elderly" (Plum, 1972).
Interestingly, all above-mentioned effects (low carbon
dioxide concentration, elevated pH, and hypoxia or low O2 pressure in cells) quoted by Dr. Plum are
caused by heavy breathing.
As a result, one can conclude that labored breathing is a normal
feature of these severe diseases.
When suffering various serious health problems (heart disease,
diabetes, cancer, AIDS, etc.) the patient’s life is very frequently
not by the main health problem, but by complications and infections,
such as in the case of bacteremic shock. Analyzing a group of patients
initially diagnosed with arteriosclerotic heart disease,
cerebrovascular insufficiency, diabetes, arthritis, several forms of
cancer, fatty liver, and alcoholism, one study showed that
complications due to pathogenic microorganisms in the blood caused 46
deaths in 50 patients (Winslow et al., 1973). Pneumonia and urinary
tract infections were the foci of pathogenic microorganisms. Now we may
ask the following: what was observed with their breathing, when not
only a part of the organism, but even the blood was polluted with
pathogens? All 50 patients, according to a table accompanying this
article, had very disturbed blood gases corresponding to very labored breathing.
Dr. Simmons and his colleagues wrote an article
"Hyperventilation and respiratory alkalosis as signs of gram-negative
bacteremia" (bacteremia being the presence of bacteria in the blood).
This extract is from the beginning of their abstract:
"Visible hyperventilation was observed clinically in
patients with Gram-negative bacteremia. Eleven patients with
Gram-negative infections and either proved or probable bacteremias were
therefore studied to see if hyperventilation might be a common response
to such bacteremia. In every case there was laboratory evidence of
hyperventilation, and in 8 cases the hyperventilation was visible to
the observer. Since only patients were studied who had no other cause
for increased ventilation, this appears to be a primary response to the
bacteremia..." (abstract, Simmons et al, 1960).
Another group of US medical professionals found that the
degree of heavy breathing has a strong correlation with over-all
mortality (Mazarra et al, 1974). Heavier breathing indicated smaller
chances of survival. Here is what they wrote in their scientific
Through a retrospective review of the randomly
selected hospital records of 114 patients, we defined four groups based
upon arterial carbon dioxide tension (PaCO2) and mode of ventilation.
Group I, with a PaCO2 of 15 mm Hg or less, consisted of 25 patients
with an over-all mortality of 88 per cent. Group II, with a PaCO2 of 20
to 25 mm Hg, consisted of 35 patients with a mortality of 77 per cent.
Group III, with a PaCO2 of 25 to 30 mm Hg, consisted of 33 patients
with a mortality of 73 per cent, and Group IV, with a PaCO2 of 35 to 45
mm Hg, consisted of 21 patients with a mortality of 29 per cent
(p<0.001). Shock and sepsis were most common in group I patients
(abstract, Mazarra et al, 1974).
This article indicated that the names of the most common
diseases to occur in all 4 groups of people were cerebrovascular
disease, hepatic coma, bronchopneumonia, and arteriosclerotic heart
The analysis of Western medical literature suggests that many critically ill
patients die in conditions of heavy and deep breathing. Up to 90% of deaths in
the severely sick take place when breathing becomes progressively heavier and
deeper, while the CP gradually approaches zero.
review of these medical professional studies indicates that
critically ill patients usually have very low carbon dioxide level due
to severe hyperventilation. Labored breathing or even
rest (dyspnea) of such patients
usually corresponds to minute ventilation of 20-25 l/min or more, while
body-oxygen content is less than 10 s. Their typical breathing
pattern is shown below.

This YouTube video "Hypocapnia,
Respiratory Alkalosis: Key Causes of Deaths In the Sick" provides the same information about hypocapnia and
respiratory alkalosis as common causes of mortality in the severely and critically ill people.
There is one page on this site that quotes over 10 clinical studies that discovered that people with chronic diseases have highest chances of death (highest mortality) , as well as highest chances of acute attacks (exacerbations due to heart attacks, strokes, seizures, etc.) during the same part of the day.
