Partial Pressure Of Oxygen » Humans are highly aerobic organisms consuming oxygen per metabolic demand.[1] In aerobic respiration, oxygen and pyruvate produce adenosine triphosphate (ATP), producing energy for the whole body.[2] To maintain homeostasis, there needs to be a gradient of pressure within the tissues that pushes oxygen by diffusion from the membranes into the tissues.[3] Many factors influence the amount of dissolved oxygen present within the cells and tissues, such as [4] Ncbi.nlm.nih.gov

Clinical use of the respiratory quotient obtained from indirect calorimetry - PubMed » Although changes in the overall and nonprotein RQ correlate to percent calories provided/required, low sensitivity and specificity limit its efficacy as an indicator of over- or underfeeding. The RQ should not be used to finely adjust the nutrition support regimen. Elevation of overall measured RQ & … Pubmed.ncbi.nlm.nih.gov

Alveolar Gas Equation » The alveolar gas equation is used to calculate alveolar oxygen partial pressure as it is not possible to collect gases directly from the alveoli. The equation is helpful in calculating and closely estimating the PaO2 inside the alveoli. The variables in the equation can affect the PaO2 inside the alveoli in different physiological and pathophysiological states. Ncbi.nlm.nih.gov
