A highly anionic organic phosphate which is present in human red blood cells at about the same molar ratio as hemoglobin. It binds to deoxyhemoglobin but not the oxygenated form, therefore diminishing the oxygen affinity of hemoglobin. This is essential in enabling hemoglobin to unload oxygen in tissue capillaries. It is also an intermediate in the conversion of 3-phosphoglycerate to 2-phosphoglycerate by phosphoglycerate mutase (EC 5.4.2.1). (From Stryer Biochemistry, 4th ed, p160; Enzyme Nomenclature, 1992, p508)

  • A discussion of CO 2 gas exchange mechanisms will further clarify the course of events resulting in hypoxaemia in COVID-19 patients. (ersjournals.com)
  • Also, due to the low resistance to diffusion of CO 2 , P aCO 2 - P ETCO 2 gap is maintained unchanged in cases when patients have oxygen diffusion limitations [ 3 ]. (ersjournals.com)
  • Surprisingly, COVID-19 patients may achieve a high P aCO 2 - P ETCO 2 gap, sometimes exceeding the predicted cut-off values of mortality in non-COVID-19 acute respiratory distress syndrome (ARDS) patients ( i.e. 10-15 mmHg) [ 4 ]. (ersjournals.com)
  • 5 ] in type L COVID-19 pneumonia patients, we have found a median P aCO 2 - P ETCO 2 gap for supine position of 20.6 mmHg and 14.9 mmHg for prone position. (ersjournals.com)
  • 6 ] reported a P aCO 2 - P ETCO 2 gap of 15 mmHg in COVID-19 patients who need a high F IO 2 to maintain S aO 2 . (ersjournals.com)
  • 27 Studies in patients with hypoxaemic respiratory failure have also shown that it is Pa o https://datingranking.net/cs/nostringsattached-recenze/ 2 rather than D o 2 -that is, diffusion rather than convection-that has the major influence on outcome. (kikuke.com)
  • Ever since Charles Darwin published his book 'On the Origin of Species by Means of Natural Selection' nearly years ago (Darwin, ), adaptive evolution has remained a critical research particular interest are insights from hypoxia-tolerant animals - species adapted to oxygen (O 2) poor aquatic or terrestrial environments (Nathaniel et al. (innovationoptimiser.com)
  • Therefore, in cases of "happy" hypoxia or silent hypoxaemia, an exaggerated increase in S aO 2 with minimal hyperoxia may take place due to the allosteric effects of oxygen rather than V ʹ A / Q ʹ maldistribution. (ersjournals.com)
  • 3-phosphogylcerate is the normal product of carboxylation and will enter the Calvin cycle. (wikipedia.org)
  • With a normal intercapillary distance illustrated in the top panels the D o 2 /V o 2 relationship is the same for all interventions. (kikuke.com)
  • Hence, a decreased V ʹ A / Q ʹ ratio will result in a higher alveolar ( P ACO 2 ) and arterial carbon dioxide tension ( P aCO 2 ), but won't change the P aCO 2 and end-tidal carbon dioxide tension ( P ETCO 2 ) gap [ 2 ]. (ersjournals.com)
  • High levels of 2,3-DPG shift the curve to the right, while low levels of 2,3-DPG cause a leftward shift, seen in states such as septic shock and hypophosphatemia. (openanesthesia.org)
