PURPOSE:
Study of fundamental physiological mechanisms of
external breathing function under long-duration orbital
flight conditions.
OBJECTIVES:
- Study of dynamics of relationship between thoracic (pectoral)
and abdominal functional breathing reserves and their realization
potential during spontaneous breathing.
- Assessment of functional state of respiratory system motility
by dynamics of thoracic and abdominal components of forced inhalation
and expiration rates.
- Study of coordinated spontaneous respiratory movements by dynamics
of relationship between thoracic and abdominal components of volumetric,
time and rate parameters of spontaneous respiratory cycle.
- Identified features of humoral-reflex regulation of breathing by
dynamics of ventilation sensitivity of thoracic and abdominal components
to chemoreceptor stimuli.
- Study of features of voluntary control of respiratory movements by
dynamics of time-dependent and precision characteristics
(spirokinography)
EXPECTED RESULTS:
Studies of cosmonaut’s respiratory system enable to get
a better understanding of basic mechanisms of pulmonary
respiration/gas exchange gravitational relations.
EXPERIMENT RESULTS:
During conduct of the experiment the following physiological
signals are recorded:
- pneumotachogram;
- thoracic pneumogram;
- abdominal pneumogram;
- pressure in oral cavity.
All experimentally derived physiological data,
as well as environmental data on the date of conducting
the experiment and personal data on the person under
examination are recorded on PCMIA card, which is to be
returned to the ground upon completion of the Expedition.
