Summary
Oxygen micro/nanobubbles (OFM-NBs) create oxygen-supersaturated fluids for improved blood oxygenation. Normal saline is ideal for infusion, while dextran aids drug delivery, offering potential in treating hypoxia and other conditions.
Area of Science:
- Biomedical Engineering
- Materials Science
- Medical Fluidics
Background:
- Microbubbles exhibit unique properties like gas solubility and free radical production.
- Oxygen microbubble fluid offers potential for oxygen delivery to hypoxic tissues.
- Comparative studies on oxygen fine micro/nanobubbles (OFM-NBs) in common infusion solutions are lacking.
Purpose of the Study:
- To investigate the generation of oxygen-supersaturated fluids using OFM-NBs.
- To assess the safety and efficacy of OFM-NBs in common infusion solutions for intravenous administration.
- To evaluate the potential of OFM-NBs for improving blood oxygenation.
Main Methods:
- Generation of oxygen-supersaturated fluids using OFM-NBs in normal saline and dextran solutions.
- Assessment of OFM-NB size for safe intravenous infusion.
- Evaluation of blood oxygenation improvement using normal saline with OFM-NBs.
Main Results:
- OFM-NBs successfully generated oxygen-supersaturated fluids.
- Normal saline was identified as preferable for a 30-minute oxygen-rich infusion.
- Dextran solution proved suitable for 1-hour drug delivery with oxygen gas.
- Normal saline containing OFM-NBs effectively improved blood oxygenation.
Conclusions:
- OFM-NBs can create safe, oxygen-supersaturated infusion fluids.
- Normal saline and dextran solutions are viable carriers for OFM-NBs with specific administration protocols.
- OFM-NB-containing fluids represent a novel approach for enhancing blood oxygenation in various medical conditions.

In aerobic fermentations, oxygen is vital for microbial growth and metabolite production. Since air comprises only about 20% oxygen and the gas is poorly soluble in water—just 9 ppm at 20°C—supplying sufficient oxygen becomes a critical challenge, especially in high-demand processes like yeast growth or citric acid production. Even a fully saturated broth may offer only a few seconds of oxygen availability.To address this, sterile or scrubbed air is introduced into the...

Oxygen Delivering System I: Nasal Cannula and Face Mask
2.6K
The human body requires oxygen to function, and when the natural process of respiration is hindered, external devices, including the following, are needed to help deliver this vital gas.
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
Oxygen percentage setting:...
