How Does the Frolov Breathing Device Work?
The main principle is relatively simple: when we breathe in and out
through the device, we get a different air composition in our lungs. In
normal conditions, when we breathe usual air, the air that we inhale
has about 21% of oxygen and 0.03% of carbon dioxide. If we start to
breathe through any device, in and out, the device traps a portion of
the exhaled air. This exhaled air has less O2 and more CO2. For example,
if we collect all exhaled air of the ordinary healthy man during normal
breathing, it will contain about 15.3% O2 and 4.2% CO2 since the human
body uses O2 and generates CO2.
When we breathe only through the device (inhalations and
exhalations), there are changes in the air composition that enters our
lungs depending on the parameters of our breathing and device. Indeed,
during our exhalation, part of the exhaled air is trapped in the
breathing device. Furthermore, the initial part of the exhaled gas has
almost no extra CO2 and about 21% O2 since this air does not
participate in gas exchange. (Ironically, it is called “dead volume”,
but in reality it is a factor promoting health due to drastic changes
in air compositions during Earth’s evolution). The last portion of the
exhaled air has highest CO2 content and lowest O2 values. Hence, the
device can trap this last portion of the exhaled air, which has high
CO2 concentration (up to about 5-6% in healthy people) and much less
oxygen (about 14-15%) than in normal air.
Hence, during our next inhalation, when we breathe only through the
device, this trapped air mixes with fresh air. Hence, most people can
more safely practice deep breathing (e.g., 3-5 large deep breathe in
one minute) when using the device without problems with low CO2 in the
lungs and other body cells. The approximate composition of the inhaled
air during breathing sessions is provided in this Table:
Inhaled air during breathing sessions
|Gas composition parameter
||Inhaled normal air
Inhaled air during
|| 1-2% CO2
The exact composition of the inhaled air is difficult to predict
because it depends on many parameters:
1) volume of trapped air in the plastic bottle (the larger this volume,
the higher the inhaled CO2 and the lower the exhaled O2);
2) amplitude of breathing (it is called tidal volume);
3) breathing frequency (it is considered in the next section);
4) metabolic rate (or CO2-generation rate).
Those people, who inhale through the nose and exhale through the
device, do not use air that is trapped in the device for their
breathing. However, since they try to make longer exhalations, their
lungs naturally accumulate more CO2 and have less O2. Hence, they
experience a similar physiological effect, but to a smaller degree.
Therefore, Frolov device breathing exercise is a type of intermittent
hypercapnic hypoxic training: “intermittent” means that it is done
only for about 15-20 minutes, but the effects are lasting for many
following hours; “hypercapnic” indicates higher CO2 levels in the
alveoli of the lungs during sessions (CO2 concentration in the arterial
blood and body cells also gets higher if there is no
ventilation-perfusion mismatch); and “hypoxic” implies temporary
reduced oxygen content in the alveoli.
Similar effects (more CO2 and less O2 in the inhaled air) take place
during other beneficial forms of breathing exercises: Buteyko breathing
exercises and Pranayama (a slow deep breathing exercise from hatha
yoga). However, the breathing device has some advantages: it allows
active movements of the respiratory muscles (mainly the diaphragm) and,
as a result, it is much easier to tolerate higher CO2 and lower O2
concentrations in the lungs and blood. Active muscular diaphragmatic
movements, together with variations in internal pressure during
inhalations and exhalations, gently stimulate all internal organs and
lymph nodes located under the diaphragm as during intensive physical
exercise. Furthermore, the device causes gentle or gradual CO2
increase, while Pranayama breath holds and Buteyko breath holds lead to
sudden CO2 upsurge, which can cause problems to some groups of people.
Hypoxic training (less O2 in the inhaled air) without hypercapnia takes
place when athletes and other people breathe air and live at high
altitude (1,500-3,000 m above the sea level).
