Abstract: Abstract. Significance: Hemoglobin oxygen saturation and red blood cell (RBC) tissue fraction are important parameters when assessing microvascular status. Functional information can be attained using temporally resolved measurements performed during stimulus–response protocols. Pointwise assessments can… read more here.

DOI: 10.3357/amhp.4804.2017
Abstract: INTRODUCTION Microgravity (μG) exposure and even early recovery from μG in combination with mild hypoxia may increase the alveolar-arterial oxygen (O2) partial pressure gradient. METHODS Four male astronauts on STS-69 (1995) and four on STS-72… read more here.

DOI: 10.3389/fphys.2021.763933
Abstract: Humans elicit a robust series of physiological responses to maintain adequate oxygen delivery during hypoxia, including a transient reduction in hemoglobin-oxygen (Hb-O2) affinity. However, high Hb-O2 affinity has been identified as a beneficial adaptation in… read more here.
