The concentration of oxygen provided in the inspired gas by five samples of a venturi mask were measured at ground level and at altitudes up to 10,000 ft for each of the oxygen port settings from 24-50% oxygen. The concentration of oxygen provided at a given setting was virtually identical for each of the five masks and was unaffected by ascent to 10,000 ft. Thus, patients with chronic hypercarbia could receive "low flow oxygen therapy" while traveling on commercial airlines without danger of acute hypo-ventilation by utilizing a venturi mask.
对于文丘里面罩的五个样本，在地面以及海拔高达10000英尺的高度，针对24%至50%氧气浓度的每个氧气端口设置，测量了吸入气体中提供的氧气浓度。在给定设置下，五个面罩中每个面罩所提供的氧气浓度实际上是相同的，并且不受上升到10000英尺高度的影响。因此，慢性高碳酸血症患者在乘坐商业航班旅行时，通过使用文丘里面罩可以接受“低流量氧气疗法”，而不会有急性通气不足的危险。
