When the lungs are unable to remove all of the carbon dioxide the body produces, it results in a condition called Respiratory Acidosis. This condition causes body fluid, especially the blood to be too acidic. There are levels of partial pressure of carbon dioxide (PCO2) in that shows whether or not the blood pH is balanced. “Normal levels adult/child: 35-45 mm Hg, Child less than 2 years: 26-41 mm Hg” (National Library, 2014). Elevated amounted of PCO2 indicates a sign of respiratory acidosis. HCO3; a concentration of hydrogen carbonate in the blood is used to determine along with pH (hydrogen ions) and CO2 source of acid base imbalance. “Normal levels of HCO3 and pH values are 22-26mmol/L and 7.35 - 7.45 respectively” (National Library, 2014).
Usually, the lungs take in oxygen and exhale CO2. Oxygen passes from the lungs into the blood. CO2 passes from the blood into the lungs. However, sometimes the lungs can’t remove enough CO2. This may be due to a decrease in respiratory rate or decrease in air movement due to an underlying condition such as asthma, COPD, pneumonia, or sleep apnea. This may cause respiratory acidosis. “The lungs and the kidneys are the major organs that help regulate your blood’s pH. The lungs flush out acid by exhaling CO2

and the kidneys excrete acids through the urine. The kidneys also regulate your blood’s concentration of bicarbonate (a base). “In response to the increase in hydrogen ion and reduction of the pH, the body responds by trying to increase plasma (HCO3) to match the increase in PCO2 and thus maintain the PCO2/HCO3 ratio” (Health line, 2015). With chronic respiratory acidosis; the kidneys hold on to bicarbonate. Treatment focuses on the underlying cause for both chronic and acute respiratory acidosis. Example if the airway is block, it needs to be cleared as soon as possible to improve airway function. Respiratory alkalosis on the other hand, is a primary decrease in Pco2 (7.5ml). Cause is an increase in respiratory rate (hyperventilation) or both. Respiratory alkalosis can be acute or chronic. The chronic form is asymptomatic, but the acute causes light-head, confusion, paresthesia, cramps and syncope. Signs include hypernea or tachypnea and carp pedal spasm. Treatment is directed at the cause, diagnosis is clinical and with ABG and serum electrolyte measurements. Regulation of pH ultimately depends on the kidney and lung, however, the ability of the two organs is decreased with physiological aging. “Moreover, the elderly is more prone to suffer from renal insufficiency and/or chronic obstructive pulmonary disease” (Institute for health, 1992). With chronic respiratory alkalosis, the kidneys dumps bicarbonate. The respiratory system compensates for the acid-base disorder. The lungs can either blow off excess acid (via CO2) to compensate for metabolic acidosis, or to a lesser extent, hold on to acid (via CO2) to compensate for metabolic alkalosis. Treatment options focuses on the underlying cause. Metabolic acidosis is a condition in which there is too much acid in the body fluids. This occurs when the body produces too much acid or when the kidneys are not removing enough acid from the body. “Metabolic acidosis is a primary decrease in HCO3(< 7.5ml) with a compensatory decrease in Paco2” (Merck Manual, 2016). Causes of metabolic acidosis include accumulation of ketones and lactic acid, renal failure and drug or toxin ingestion (high anion gap) and renal HCO3-loss. The body responds to metabolic acidosis by trying to restore the PCO2/HCO3 ratio. This is achieved by reducing the PCO2, and the reduction of PCO2 is accomplished by increasing alveolar ventilation. With Metabolic acidosis, ventilation increase to blow of CO2. Treatment is aimed at the underlying condition, in some cases, sodium bicarbonate may be given to reduce the acidity of the blood. Metabolic alkalosis is also an acid base disorder characterized by an elevation in HCO3 (>22mmol/d) above the normal range, which leads to a reduction in the PCO2/HCO3-ratio and subsequently a reduction in hydrogen ion concentration.
“In response to the reduction in hydrogen ion and elevation in pH the body responds by trying to elevate the PCO2 to match the increase in HCO3 and thus maintain PCO2/HCO3 ratio too” (University of Connecticut, 2006). With metabolic alkalosis, ventilation decreases to hold on to CO2. Treatment is focused on the cause, and IV 0.9% saline solution for CI-responsive metabolic alkalosis. Underlying conditions are treated, with particular attention paid to correction of hypovolemia and
hypokalemia. Everyday stability of acid -base composition of systemic circulation is critically dependent on the excretion of acid in urine. Function declines with advancing age, therefore, an ever increasing fraction of daily acid load will be retained which can only be compensated for by increased release of bone base.
Air then travels to the bronchioles which are narrow (bronchoconstriction) due to the natural defence in keeping irritants out of the airway, causing wheezing breath sounds.(Eldridge, 2016) The air then proceeds to the alveoli, which are weakened and damaged air sacs due to the progression of the disease, that are unable to efficiently move O2 into the blood stream and gas exchange CO2 to be expelled through exhale, causing hypoxemia, lethargy, dyspnoea and high CO2 reading. (“Lung conditions - chronic obstructive pulmonary disease (COPD),”
The circulatory system and respiratory system share a highly important relationship that is crucial to maintaining the life of an organism. In order for bodily processes to be performed, energy to be created, and homeostasis to be maintained, the exchange of oxygen from the external environment to the intracellular environment is performed by the relationship of these two systems. Starting at the heart, deoxygenated/carbon-dioxide (CO2)-rich blood is moved in through the superior and inferior vena cava into the right atrium, then into the right ventricle when the heart is relaxed. As the heart contracts, the deoxygenated blood is pumped through the pulmonary arteries to capillaries in the lungs. As the organism breathes and intakes oxygenated air, oxygen is exchanged with CO2 in the blood at the capillaries. As the organism breathes out, it expels the CO2 into the external environment. For the blood in the capillaries, it is then moved into pulmonary veins and make
The first test showed a decrease in blood pH and a major increase in the partial pressure of oxygen. The patient was placed on a ventilator during surgery on the date of admission, which could be the reason as to why his partial pressure of oxygen was increased. The patient’s blood pH was low in the first test. While it was barely in the normal range, the patient’s bicarb was close to being low as well. The patient was injured which resulted in fluid shifts that could have affected the amount of bicarbonate in the patient’s blood, resulting in a decrease in the blood’s pH. This means the patient was at risk for metabolic acidosis. The next day the patient’s blood pH had increased to a normal level and the bicarbonate level had also increased. The patent’s partial pressure of oxygen had also decreased, due to a decrease in the fraction of inspired oxygen, possibly from changes to the setting of the
The cause for the acid-base balance would be the sedative, the patient’s weight which is obese, respiratory, bicarbonate and metabolic problem.
To better understand how COPD affects an individual you should first know how the lungs function. When you breathe in air it first goes through your trachea then into your bronchioles. Once in the bronchioles the air goes to the air sacs called alveoli. In the alveoli, the gas exchange occurs with the capillaries. Gas exchange is when the oxygen enters the bloodstream and carbon dioxide enters the alveoli. During the breathing process, alveoli will inflate when inhaling and deflate while exhaling.

When diagnosed with hyponatremia treatment usually immediately begins. Treatment must be a restriction of both salt and water (Gheorghita et. al 2010). Hyponatremic patients must receive a slow increase in sodium with a restriction of liquids. Intravenous hypertonic saline solution of 3% NaCl can be administered to patients who have been diagnosed with hyponatremia. There is a precise formula that is used in determining the quantity of NaCl that is used in increasing sodemia and the rate at which it should be administered (Gheorghita et. al 2010).
...on dioxide, within the body, affecting the pH balance of the blood. This will then affect proteins within the body, being known as enzymes, which can only function if their surrounding environment is in balance. Any alteration to this environment, will prevent the enzymes from functioning effectively.
It is when much needed oxygen is obtained by the body in order for respiration to take place and the waste CO2 is taken out of the body. In us mammals, the exchange takes place in the lungs which contain a large number of alveoli. These are sponge-like structures in which the diffusion takes place. They are highly adapted to diffuse the gases as they give a large surface area for exchange of the gases.
Chronic bronchitis is a disorder that causes inflammation to the airway, mainly the bronchial tubules. It produces a chronic cough that lasts three consecutive months for more than two successive years (Vijayan,2013). Chronic Bronchitis is a member of the COPD family and is prominently seen in cigarette smokers. Other factors such as air pollutants, Asbestos, and working in coal mines contributes to inflammation. Once the irritant comes in contact with the mucosa of the bronchi it alters the composition causing hyperplasia of the glands and producing excessive sputum (Viayan,2013). Goblet cells also enlarge to contribute to the excessive secretion of sputum. This effects the cilia that carry out the mechanism of trapping foreign bodies to allow it to be expelled in the sputum, which are now damaged by the irritant making it impossible for the person to clear their airway. Since the mechanism of airway clearance is ineffective, the secretion builds up a thickened wall of the bronchioles causing constriction and increasing the work of breathing. The excessive build up of mucous could set up pneumonia. The alveoli are also damaged enabling the macrophages to eliminate bacteria putting the patient at risk for acquiring an infection.
Acid rain has been proven to have damage forests, fresh waters and soils, killing insect and aquatic life-forms. It also causes damage to buildings and impacts on human health. Many people do not know what acid rain actually is. Acid rain is any form of precipitation that is unusually acidic, low pH levels, higher than normal amounts of sulfuric and nitric acid, occurs naturally and from man made sources. Forms when gases react in the atmosphere with water, oxygen, and other chemicals (what is acid rain?). The only water that will not have some amount of acidity is pure water. Pure water has a pH of 7 which is neutral; regular, unpolluted rain water has a pH of around 5.6. The acidity in rain water comes from the presence of Carbon Dioxide, Nitrogen Oxide, and Sulfur Dioxide. CO2 reacts with water to form carbonic acid. Nitrogen and water react during lightning storms, forming Nitric Oxide. NO is then oxidized to form N02. The NO2 reacts with water to form nitric acid. Due to this, the pH is lowered to be slightly acidic (Acid Rain). Acid rain can occur naturally in the environment, but the problem occurs when human interaction is the cause of the acidic levels.
...ystems action leading to coma and death. Alkalosis is when the bloods pH increases to become more alkaline, it results in over excitement of the nervous system leading to convulsions. There are key pH changers that can occur; vomiting can lead to alkalosis, diarrhea can lead to acidosis. Kidney disfunction could happen either way, if the kidneys get messed up then blood pH can be all over the place.
Alveolar hyperventilation causes a decreased partial pressure of arterial carbon dioxide (PaCO2). The decrease in PaCO2 increases the ratio of bicarbonate concentration to PaCO2 which increases the pH level. The decrease in PaCO2 develops when a strong respiratory stimulus causes the respiratory system to remove more carbon dioxide than is produced. Respiratory alkalosis can be acute or chronic. Acute respiratory alkalosis is when the PaCO2 level is below the lower limit of normal and the serum pH is alkalemic. Chronic respiratory alkalosis is when the PaCO2 level is below the lower limit of normal, but the pH level is relatively normal or near normal. Respiratory alkalosis is the most common acid-base abnormality observed in patients who are critically ill. It is associated with numerous illnesses and is a common finding in patients on mechanical ventilation. Many cardiac and pulmonary disorders can occur with respiratory alkalosis. When respiratory alkalosis is present, the cause may be a minor or non–life-threatening disorder. However, more serious disease processes should also be considered in the differential diagnosis (Byrd, 2017). Hyperventilation is most likely the underlying cause of respiratory alkalosis. Hyperventilation is also known as over breathing (O’Connell, 2017).
Acid-Base balance is the state of equilibrium between proton donors and proton acceptors in the buffering system of the blood that is maintained at approximately pH 7.35 to 7.45 under normal conditions in arterial blood. It is important to regulate chemical balance or homeostasis of body fluids. Acidity or alkalinity has to be regulated. An acid is a substance that lets out hydrogen ions in solution. Strong acid like hydrochloric acid release all or nearly all their hydrogen ions and weak acids like carbonic acid release some hydrogen ions.
The roles of the circulatory and respiratory system both carry important responsibilities and are essential in their jobs to the human body. The circulatory system is one, if not the, most important system in the human body. The circulatory system is made up of the heart, blood, and blood vessels. Within the blood vessels, there are three types: arteries, veins, and capillaries. The heart is an organ made up of cardiac muscle that has a role similar to a pump. When the muscles in the heart contract, it pumps fresh blood away from the heart, through a main artery called the aorta, and to the organs and cells of the body. Nutrients and oxygen then enter the cells through diffusion of the tissues. The respiratory system transports oxygen to the circulatory system. When transporting oxygen to the circulatory system, this will in turn transport oxygen to the rest of the cells in the body. Aside from transporting oxygen to the body, the respiratory system also plays a role in the removal of carbon dioxide and other contaminants in the body. These two systems effectively and efficiently work together in order to supply the body with oxygen and remove carbon dioxide and any other
