The oxygen-enriched air in discharged to the outside of the chamber through a discharge line 6, and the nitrogen-enriched air is returned to the inside of the storage chamber 1 through a recovery line 7. The amt. of air corresponding to that released from the storage chamber 1 is always...
Oxygen is a colourless gas that exists in large quantities in the air. All plants and animals need oxygen in order to live. e.g. The human brain needs to be without oxygen for only four minutes before permanent damage occurs. 人的大脑缺氧4分钟后便会造成永久性损伤。
We conducted a blinded, prospective, randomized control trial to determine which oxygen-titration strategy was most effective at achieving and maintaining oxygen saturations of 85% to 92% during delivery-room resuscitation.Infants born at 32 weeks' gestation or less were resuscitated either with a st...

Conclusion:Installing an oxygen-enric hed room at high altitude is an ideal way to supply oxygen, which could decrease the myocardial enzyme of body and improve the oxygenation function . 展开 关键词: High altitude Oxygen enrichment of room air Exhaustion-exercise Myocardial enzyme ...
room air is inhaled through the valve, and air which is exhaled goes through a tube into an MMC. The cart measures the amount of oxygen and carbon dioxide in the exhaled air, as well as the volume of air. Finally, the amount of oxygen consumed can be computed after correction for...
air into a container that separates oxygen from room air and concentrates it to provide oxygen continuously to users. Compared with other oxygen supply devices like compressed oxygen cylinder, the oxygen concentrator is larger in size and it may restrict the movement of the use...
Raman measurements were performed at room temperature, without polarization detection using a T64000 Horiba Jobin-Yvon spectrometer configured in a backscattering geometry and a single subtractive operation mode. The samples were excited with the 514.5 nm line of an Ar+ laser. View article...
Fifty-one participants completed the study interventions and were included in the final analysis. Twenty-nine received oxygen-enriched air and twenty-two received room air. Four participants who completed less than 2 weeks (one—oxygen-treated, three—air-treated) were not included in the analysis...
