초록
Underwater breathing requires a large amount of oxygen. As water contains limited dissolved oxygen, devices must be sufficiently large to obtain the required oxygen. Exhaled breath, which contains a large amount of oxygen, can be reused to make devices compact and portable. In this work, gases with the characteristics of exhaled breath were mixed with water using a hollow fiber membrane. The gases were mixed with water in the form of small bubbles, which increased the contact area between the gases and water. The mixed state was visualized by increasing the amount of prepared gases. Dissolved gases were separated from water con-taining the prepared gases. The amount of separated gases increased with the amounts of prepared gases and water. The separated dissolved gases could be used for underwater respiration.
Abstract
Underwater breathing requires a large amount of oxygen. As water contains limited dissolved oxygen, devices must be sufficiently large to obtain the required oxygen.

The gases were mixed with water in the form of small bubbles, which increased the contact area between the gases and water. The mixed state was visualized by increasing the amount of prepared gases. Dissolved gases were separated from water con-taining the prepared gases. The amount of separated gases increased with the amounts of prepared gases and water. The separated dissolved gases could be used for underwater respiration.
