POTENTIAL CAUSES OF THE MEDICAL PRACTICE BAD RESULTS DERIVED FROM ERRORS IN THE TRADITIONAL INTERPRETATION OF THE RESPIRATORY FUNCTION AND PULMO-CARDIO-CIRCULATORY DYNAMICS
The Lung displays a structural and functional Design to work under Vagus Sympathetic co-ordination and command which must be re-interpreted now from the physic-mathematical perspective applied to physiological needs. To achieve this proposal, we must underline the following fundamental concepts:
The functional capacities of the airways as a whole as that of each specific segment, jointly with Force potential variations able to be generated by cyclic contraction-relaxation of their walls muscles, are correlatives to the atmospheric mass of air per volume unit at the organism's adaptation level. These capacities and force variations are also correlative to the integrated pulmo-cardio-circulatory dynamics, which must balance the fluids, blood and air at each side of the alveolo-capillary membrane.
DOMINANT BELIEFS THAT MUST BE SUBMITTED TO DISCUSSION.
1. The Lung is a passive Organ.
2. The Diaphragm is the motor of the Lung.
3. The respiratory muscles are the Diaphragm, intercostals and those known as auxiliary muscles.
4. Adrenaline is a bronchodilator.
5. All secondary concepts derived from the above named concepts.
FUNDAMENTAL CONCEPTS SUGGESTED TO REPLACE TRADITIONAL BELIEFS.
1. The Lung is an autonomic active Organ, under Vagus-Sympathetic command.
2. The Diaphragm is the main auxiliary muscle of the Lung, which responds to the Lungs demand by a viscero-somatic reflex.
3. The Respiratory muscles are those of the airways or Reissessens muscles.
4. All other muscles recruited during each Respiratory Cycle are only reflex auxiliary muscles for viscero-somatic functional integration of the Trunk as a working unit.
5. Adrenaline is a broncho-constrictor. It shows positive inotropic and chronotropic effect, similar to cardiac effects, thus enabling their functional integration at the alveolo-capillary units.
6. The Thorax Walls. Diaphragm and Rib Cage, are exterior support of the Lung, to which they respond in an integrated chain of reflexes.
7. The Respiratory Apparatus of each individual starts working with its natural adaptation to the Atmosphere during birth, according to the following factors.
7.1 Mass of gases per volume unit constituting the atmospheric air at the level of our natural adaptation. This is the Physical-natural primary factor for the work of the Lung, enabling Pulmonary Respiration and consequently the cells Respiration.
7.2 Oxygen, a natural element in Gas State; specific for organic combustion, only constitute 21% of the a atmospheric air. Therefore, pure Oxygen is not apt for Respiration. Nitrogen constitutes 79% of the gaseous-mass demanded by the pulmonary structure to fulfil its mechanical function.
7.3 Pulmo-cardio-circulatory dynamics and mass of air per volume-unit constitute the fundamental equation for adaptation and maintenance of the new born life, that is to say for maintenance of Human Life on Earth, as well as of all similar species shearing our Habitat.
7.4 Dynamics leading to blood gas exchange is performed in multiple small units defined as lobule, of which the finest bronchioli contain the alveoli or surface units for selective gas diffusion leading to gas exchange with the blood. The pulmonary lobuli perform a rhythm commanded by the Sympathetic nerve on Vagus tone, just like the Heart, leading to the needed pulmo-cardiac functional integration.
