Upper respiratory tract infection s are probably the most common infections in the world. Most of the respiratory tract exists merely as a piping system for air to travel in the lungs, and alveoli are the only part of the lung that exchanges oxygen and carbon dioxide with the blood . Moving down the respiratory tract starting at the trachea, the tubes get smaller and divide more and more. There are estimated to be about 20 to 23 divisions, ending up at an alveolus. Even though the cross sectional area of each bronchus or bronchiole is smaller, because there are so many, the total surface area is larger. This means there is less resistance at the terminal bronchioles. Most resistance is around the 3 4 division from the trachea due to turbulence.

unreferenced date December 2010 The respiratory center RC is located in the medulla oblongata , which is the lowermost part of the brain stem . The RC receives controlling signals of neural, chemical and hormonal nature and controls the rate and depth of respiratory movements of the diaphragm and other respiratory muscles. Injury to this center may lead to central respiratory failure , which necessitates mechanical ventilation, but usually the prognosis is grave.kjjlkl In healthy individuals the presence of elevated carbon dioxide levels in the blood is the stimulant that the RC responds to in order to signal the respiratory muscles to breathe. Chemoreceptors found in carotid and aortic bodies are responsible for detecting this CO2 . Individuals who suffer from Chronic Obstructive Pulmonary Disease usually have a chronically elevated level of carbon dioxide present in their blood due to their diminished lung function. As a result, their specific chemoreceptors become desensitised to the hypercapnia and instead respond to a decreased amount of oxygen present. The groups of nerve cells in the brain which regulates the respiration rhythmically are collectively known as respiratory centers. Groups Respiratory centre is divided four major groups Inspiratory centre Dorsal respiratory group Location Dorsal portion of medulla Nucleus Nucleus tractus solitarius Function causes inspiration while stimulated. Expiratory centre Ventral respiratory group Location Antero lateral part of medulla, about 5 mm anterior and lateral to dorsal respiratory group Nucleus Nucleus ambiguous and nucleus retro ambiguous.

The respiratory quotient or RQ or respiratory coefficient , is a unitless number used in calculations of basal metabolic rate BMR when estimated from carbon dioxide production. Such measurements, like measurements of oxygen uptake, are forms of indirect calorimetry . It is measured using Ganong s Respirometer . It can be used in the alveolar gas equation . Calculation The respiratory quotient RQ is calculated from the ratio RQ CO sub 2 eliminated sub O sub 2 consumed sub where the term eliminated refers to carbon dioxide CO sub 2 sub removed eliminated from the body. In this calculation, the CO sub 2 sub and O sub 2 sub must be given in the same units, and in quantities proportional to the number of molecules. Acceptable inputs would be either mole unit moles , or else volumes of gas at standard temperature and pressure time units may be included, but they cancel out since they must be the same in numerator and denominator . Many metabolized substances are compounds containing only the elements carbon , hydrogen , and oxygen . Examples include fatty acids , glycerol , carbohydrates , deamination products, and ethanol . For complete oxidation of such compounds, the chemical equation is C sub x sub H sub y sub O sub z sub x y 4 z 2 O sub 2 sub x CO sub 2 sub y 2 H sub 2 sub O and thus metabolism of this compound gives an RQ of x x y 4 z 2 .

It is one of four basic categories of disruption of acid base homeostasis . Terminology Alkalosis refers to a high pH in tissue . Alkalemia refers to a high pH in the blood . Types There are two types of respiratory alkalosis chronic medicine chronic and acute medicine acute . Acute respiratory alkalosis occurs rapidly. During acute respiratory alkalosis, the person may lose consciousness where the rate of ventilation will resume to normal. Chronic respiratory alkalosis is a more long standing condition. For every 10 mM drop in pCO sub 2 sub in blood, there is a corresponding 5 mM of bicarbonate ion drop. The drop of 5 mM of bicarbonate ion is a compensation effect which reduces the alkalosis effect of the drop in pCO sub 2 sub in blood. This is termed metabolic compensation.
