    StatPearls Publishing: Treasure Island (FL) Patel Sagar S Mohiuddin Shamim S. SS Imam Abdulrahman Bin Faisal University, Dammam BOOK
  • The oxyhemoglobin dissociation curve is a vital tool for comprehending how blood transports and releases oxygen.Oxygen is carried throughout the body primarily by a protein molecule, hemoglobin, which is present inside red blood cells. Oxygen can also be carried throughout the body by dissolving in blood plasma, but this dissolved portion only constitutes a small portion of the total amount of ox…
  • Human non-REM sleep and the mean global BOLD signal. [Journal Article]
    J Cereb Blood Flow Metab 2018; :271678X18791070McAvoy MP, Tagliazucchi E, … Raichle ME
  • A hallmark of non-rapid eye movement (REM) sleep is the decreased brain activity as measured by global reductions in cerebral blood flow, oxygen metabolism, and glucose metabolism. It is unknown whether the blood oxygen level dependent (BOLD) signal undergoes similar changes. Here we show that, in contrast to the decreases in blood flow and metabolism, the mean global BOLD signal increases with s…
  • StatPearls: Physiology, Oxyhemoglobin Dissociation Curve [BOOK]
    StatPearls Publishing: Treasure Island (FL) Kaufman Daniel P. DP SUNY Upstate Medical University Dhamoon Amit S. AS SUNY Upstate Medical University BOOK
  • Oxygen is primarily transported throughout the body in red blood cells, attached to hemoglobin molecules. Oxygen is also dissolved directly in the bloodstream, but this dissolved fraction contributes little to the to the total amount of oxygen carried in the bloodstream. Henry’s Law states that the dissolved fraction is proportional to the atmospheric pO2, but the solubility of oxygen is so low t…
  • The influence of reducing fever on blood oxygen saturation in children. [Clinical Trial]
    Eur J Pediatr 2018; 177(1):95-99Goldberg S, Heitner S, … Picard E
  • CONCLUSIONS: Pyrexia was associated with decreased SpO2 in normoxemic children. The influence of pyrexia in children with low-normal oxygen saturation is expected to be much higher because of the non-linear shape of the ODC. Physicians treating patients with fever should be aware of this effect, especially in patients with borderline hypoxia. What is Known: • High blood temperature decreases the affinity of oxygen to hemoglobin. • It is not known whether fever would decrease SpO 2 . What is New: • Fever is associated with decreased SpO 2 .
