  • Other features of the disease include a tendency toward leukocytosis, blood clot formation, abnormal lung function (restrictive lung disease, pulmonary hypertension, and impaired lung diffusion capacity), very high blood levels of the cytokine vascular endothelial growth factor (VEGF), and an overlap with the signs and symptoms of multicentric Castleman disease. (wikipedia.org)

  • The fibrosis in IPF has been linked to cigarette smoking, environmental factors (e.g. occupational exposure to gases, smoke, chemicals or dusts), other medical conditions including gastroesophageal reflux disease (GERD), or to genetic predisposition (familial IPF). (wikipedia.org)
  • IPF is believed to be the result of an aberrant wound healing process including/involving abnormal and excessive deposition of collagen (fibrosis) in the pulmonary interstitium with minimal associated inflammation. (wikipedia.org)
  • Respiration
  • Nitrite (NO 2 − ), historically considered inert, functions as a reservoir for nitric oxide (NO). 1 During physiological hypoxia and pathological ischemia, nitrite is reduced to NO, regulating hypoxic vasodilation, cellular respiration, mitochondrial reactive oxygen species (ROS) generation, angiogenesis, 2 and cellular death programs.

  • Although, exercise training does not directly improve lung function, it causes several physiological adaptations to exercise which can improve physical condition. (wikipedia.org)
  • blood
  • CD gas is rapidly absorbed in blood and peritoneum, colorless, does not support combustion, and generally has few systemic side effects in healthy patients. (blogs.com)
  • Specifically, CD is relatively benign because most of the gas in the blood is bound to terminal amino groups of hemoglobin or converted to bicarbonate. (blogs.com)

  • Blood tests to assess kidney function like serum creatinine and a normal ua . (healthtap.com)
  • These veins join to form the pulmonary veins, which return the oxygenated blood to the left atrium. (thefreedictionary.com)
  • pulmonary function tests tests used to evaluate lung mechanics, gas exchange, pulmonary blood flow, and blood gases and pH. (thefreedictionary.com)
  • Breath gas concentration can then be related to blood concentrations via mathematical modeling as for example in blood alcohol testing. (wikipedia.org)
  • The simplest model relating breath gas concentration to blood concentrations was developed by Farhi C A = C v ¯ λ b:air + V ˙ A / Q ˙ c , {\displaystyle C_{A}={\frac {C_{\bar {v}}}{\lambda _{\text{b:air}}+{\dot {V}}_{A}/{\dot {Q}}_{c}}},} where C A {\displaystyle C_{A}} denotes the alveolar concentration which is assumed to be equal to the measured concentration. (wikipedia.org)
  • Some of these features are due to chronic hypoxemia (oxygen deficiency in the blood), are not specific for IPF, and can occur in other pulmonary disorders. (wikipedia.org)
  • Blood moves from the tissue capillary to the pulmonary capillary where CO2 is exchanged at the lung. (wikipedia.org)
  • In the pulmonary capillary, bicarbonate can not simply diffuse either into the Red Blood Cell or the alvioli. (wikipedia.org)
  • In this way, plasma HCO3- can be converted to CO2 within the plasma compartment and exchanged with the alvioli without the requirement of returning the HCO3- to the interior of the Red Blood Cell. (wikipedia.org)
  • The fluid coating is produced by the body in order to facilitate the transfer of gases between blood and alveolar air. (wikipedia.org)
  • gills
  • Gas exchange takes place in the gills which consist of thin or very flat filaments and lammelae which expose a very large surface area of highly vascularized tissue to the water. (wikipedia.org)
  • Nitrogen
  • In nitrogen fixation by diazotrophic bacteria, and denitrification by heterotrophic bacteria (such as Paracoccus denitrificans and various pseudomonads), nitrogen gas is exchanged with the environment, being taken up by the former and released into it by the latter, while giant tube worms rely on bacteria to oxidize hydrogen sulfide extracted from their deep sea environment, using dissolved oxygen in the water as an electron acceptor. (wikipedia.org)
  • airways
  • At the end of inhalation the airways are filled with environmental air, which is exhaled without coming in contact with the gas exchanger. (wikipedia.org)
  • Peripheral
  • Peripheral chemoreceptor function after carbonic anhydrase inhibition during moderate-intensity exercise. (biomedsearch.com)
  • To reduce symptoms To improve knowledge of lung condition and promote self-management To increase muscle strength and endurance (peripheral and respiratory) To increase the exercise tolerance To reduce length of hospital stay To help to function better in day-to-day life To help in managing anxiety and depression Reduction in number of days spent in hospital one year following pulmonary rehabilitation. (wikipedia.org)
  • symptoms
  • 3 More of the miners than controls reported symptoms of chronic bronchitis (31% versus 5%) and their lung function also tended to be worse. (bmj.com)
  • In summary, despite significant preoperative symptoms, cardiopulmonary performance during exercise in patients with tetralogy of Fallot and absent pulmonary valve is similar to patients with tetralogy of Fallot repaired with a transannular patch. (biomedsearch.com)
  • molecule
  • D is the diffusion coefficient, which will differ from gas to gas, and from membrane to membrane, according to the size of the gas molecule in question, and the nature of the membrane itself (particularly its viscosity, temperature and hydrophobicity). (wikipedia.org)
  • diffusion
  • Gas exchange is the biological process by which gases move passively by diffusion across a surface. (wikipedia.org)
  • The exchange of gases occurs as a result of diffusion down a concentration gradient. (wikipedia.org)
  • The negative sign indicates that the diffusion is always in the direction that - over time - will destroy the concentration gradient, i.e. the gas moves from high concentration to low concentration until eventually the inside and outside compartments reach equilibrium. (wikipedia.org)
  • In general, the higher the concentration gradient across the gas-exchanging surface, the faster the rate of diffusion across it. (wikipedia.org)
  • disorders
  • Pulmonary function testing in patients with neuromuscular disorders helps to evaluate the respiratory status of patients at the time of diagnosis, monitor their progress and course, evaluate them for possible surgery, and gives an overall idea of the prognosis. (wikipedia.org)
  • volatile organic c
  • Breath gas analysis is a method for gaining non-invasive information on the clinical state of an individual by monitoring volatile organic compounds present in the exhaled breath. (wikipedia.org)
  • The area of modern breath testing commenced in 1971, when Nobel Prize winner Linus Pauling demonstrated that human breath is a complex gas, containing more than 200 different volatile organic compounds. (wikipedia.org)
  • rehabilitation
  • In general, pulmonary rehabilitation refers to a series of services that are administered to patients of respiratory disease and their families, typically to attempt to improve the quality of life for the patient. (wikipedia.org)
  • Pulmonary rehabilitation may be carried out in a variety of settings, depending on the patient's needs, and may or may not include pharmacologic intervention. (wikipedia.org)
  • Reduced exacerbations post pulmonary rehabilitation. (wikipedia.org)
  • Although there are no universally accepted procedure codes for pulmonary rehabilitation, providers usually use codes for general therapeutic processes. (wikipedia.org)
  • The goal of pulmonary rehabilitation is to help improve the well-being and quality of life of the patient and their families. (wikipedia.org)
  • Exercise is the cornerstone of pulmonary rehabilitation programs. (wikipedia.org)
  • assess
  • Aim: To assess the pulmonary function parameters including alveolar gas exchange in patients with Type 2 Diabetes mellitus and to find the influence of hyperglycaemia and duration of diabetes. (jcdr.in)
  • To assess this hypothesis, nine patients with tetralogy of Fallot and absent pulmonary valve underwent exercise testing and were compared to 38 patients with tetralogy of Fallot repaired using a transannular patch. (biomedsearch.com)
