  • While changes in DM were due to the reduction of lung volume, changes in Vc were not limited to volume loss, since the Vc/alveolar volume ratio decreased significantly. (unimi.it)
  • A brief course of anesthesia and controlled ventilation leads to: (1) alveolar damage, which is correlated with lung strain and perfusion, and (2) impaired gas exchange mainly due to volume loss but also to reduced aerated lung perfusion. (unimi.it)
  • perfusion
  • Once dissolved, distribution of the dissolved gas may be by diffusion, where there is no bulk flow of the solvent, or by perfusion where the solvent (blood) is circulated around the diver's body, where gas can diffuse to local regions of lower concentration. (wikipedia.org)
  • Initially, this helps compensate for heart failure by maintaining blood pressure and perfusion, but places further strain on the myocardium, increasing coronary perfusion requirements, which can lead to worsening of ischemic heart disease. (wikipedia.org)
  • Hypovolemia can be recognized by tachycardia, diminished blood pressure, and the absence of perfusion as assessed by skin signs (skin turning pale) and/or capillary refill on forehead, lips and nail beds. (wikipedia.org)
  • contraction
  • As such, it can be caused by a wide number of conditions, including myocardial infarction (in which the heart muscle is starved of oxygen and dies), hypertension (which increases the force of contraction needed to pump blood) and amyloidosis (in which misfolded proteins are deposited in the heart muscle, causing it to stiffen). (wikipedia.org)
  • In heart failure, this mechanism fails, as the ventricle is loaded with blood to the point where heart muscle contraction becomes less efficient. (wikipedia.org)
  • The increase in ventricular volume also causes a reduction in stroke volume due to mechanical and inefficient contraction of the heart. (wikipedia.org)
  • reduces blood

  • oxygen
  • Erythrocytes are the red blood cells that contain hemoglobin, the protein that transports oxygen within the body, as well as carry the waste carbon dioxide produced by the body. (faqs.org)

  • The lungs have a unique blood supply, receiving deoxygenated blood from the heart in the pulmonary circulation for the purposes of receiving oxygen and releasing carbon dioxide, and a separate supply of oxygenated blood to the tissue of the lungs, in the bronchial circulation. (wikipedia.org)
  • The signs and symptoms of the major stages of hypovolemic shock include: Emergency oxygen should be immediately employed to increase the efficiency of the patient's remaining blood supply. (wikipedia.org)
  • Topics investigated would include: biology (blood changes, sleep patterns, oxygen toxicity), decompression and decompression sickness, microbiology and mycology. (wikipedia.org)
  • sodium
  • The greater the level of sodium remaining in the body, the greater the amount of water that will be retained by the body, which has the effect of maintaining blood volumes. (faqs.org)
  • This happens as a result of sodium transport from the lumen into the blood by the Na+/K+ATPase in the basolateral membrane of the epithelial cells. (wikipedia.org)
  • Sodium, and therefore blood volume, is difficult to regulate internally. (wikipedia.org)
  • Thus, a problem in high blood potassium can be resolved somewhat without jettisoning too much of what is sometimes a dangerously scarce mineral that can not be pumped actively independently from sodium. (wikipedia.org)
  • capillaries
  • The other main component of the brain is grey matter (actually pinkish tan due to blood capillaries), which is composed of neurons. (wikipedia.org)
  • dehydration
  • In cases in which loss of blood volume is clearly attributable to bleeding (as opposed to, e.g., dehydration), most medical practitioners of today prefer the term exsanguination for its greater specificity and descriptiveness, with the effect that the latter term is now more common in the relevant context. (wikipedia.org)
  • dilution
  • The concentration of the I-131 in the blood is determined from the blood radioactivity against the standard, which has a known I-131 dilution in a known volume. (wikipedia.org)
  • A multi-point method of determining a time-zero blood volume by the tracer dilution technique. (google.ca)
  • internally
  • Obvious signs of external bleeding should be noted while remembering that people can bleed to death internally without any external blood loss. (wikipedia.org)
  • Patients
  • In patients with cardiogenic shock, where the heart's ventricles are not able to pump enough blood, calcium channel blockers exacerbate the situation by preventing the flow of calcium ions into cardiac cells, which is required for the heart to pump. (wikipedia.org)
  • correlation
  • A significant correlation was found between total blood volume (TBV) and EDV before (r = 0.66, p less than 0.005) and after dialysis (r = 0.61, p less than 0.001). (ahajournals.org)
  • stroke volume
  • stroke volume (SV) decreased from 108 +/- 36 to 86 +/- 33 ml (p less than 0.001) without change in ejection fraction (from 0.73 +/- 0.09 to 0.74 +/- 0.11). (ahajournals.org)

  • Although the toxic peptides are generally small (about 60 amino acids), their size is sufficient to prevent them from crossing epithelial layers like the blood-brain barrier. (wikipedia.org)

  • Unless the person illegally ingesting these substances possessed a high baseline of physical conditioning, such as a very fit, highly trained endurance athlete, the additional red blood cell and blood volume capabilities these techniques afforded would be negligible. (faqs.org)
