Development of a Patch-Type Flexible Oxygen Partial Pressure Sensor [PDF]

open access: yesIEEE Journal of Translational Engineering in Health and Medicine, 2020
Oxygen concentration in living organisms is one of the important vital indicators in emergency care and bedside medical settings. However, the oximetry method has limitations: the measurement site is limited to the tissue containing blood and the ...

Oxygen Partial Pressure Is a Rate-Limiting Parameter for Cell Proliferation in 3D Spheroids Grown in Physioxic Culture Condition. [PDF]

open access: yesPLoS ONE, 2016
The in situ oxygen partial pressure in normal and tumor tissues is in the range of a few percent. Therefore, when studying cell growth in 3D culture systems, it is essential to consider how the physiological oxygen concentration, rather than the one in ...

Relating oxygen partial pressure, saturation and content: the haemoglobin–oxygen dissociation curve [PDF]

open access: yesBreathe, 2015
Key PointsIn clinical practice, the level of arterial oxygenation can be measured either directly by blood gas sampling to measure partial pressure (PaO2) and percentage saturation (SaO2) or indirectly by pulse oximetry (SpO2).This review addresses the strengths and weaknesses of each of these tests and gives advice on their clinical use.The ...

Oxygen: A Stimulus, Not “Only” a Drug

open access: yesMedicina, 2021
Depending on the oxygen partial pressure in a tissue, the therapeutic effect of oxygenation can vary from simple substance substitution up to hyperbaric oxygenation when breathing hyperbaric oxygen at 2.5–3.0 ATA. Surprisingly, new data showed that it is

Ferromagnetism enhancement by increasing oxygen vacancies in Co-doped ZnO thin films

open access: yesAIP Advances, 2022
In the reported study, thin films of ZnO doped with 10 wt. % Co were fabricated by pulsed laser deposition under different oxygen partial pressures. The results of x-ray photoelectron spectroscopy show that the valence state of the Co ions is 2+ and that
