  • Measurement of functional residual capacity by sulfur

    Comparison with nitrogen washout (FRCN2) in five postoperative patients gave the following: FRCSF6 = 59 ml + 0.97 X FRCN2, r = 0.97. FRCSF6 during N2O/O2 ventilation was the same as during air/O2 ventilation in a group of paralyzed patients. The measurement system has not been tested in patients with obstructive lung disease.

    ficient for SF6 and air mixtures have been measured by the steady-state Townsend method for 51 S E/p20 S 160 V cm- Torr (155 C E/N 6 386 Td). The results show that the , of the mixtures does not vary linearly with the fractional SF6 partial pressure k and has a minimum value at a fixed value of E/p20.Cited by: 28

    Oxygen (O2) is a colourless gas that makes up 21 percent of Earths atmosphere. It is one of the life-sustaining elements on Earth and also the most reactive of the non-metallic elements. Oxygen forms compounds by reaction with practically any other element, as well as by reactions that displace elements from their combinations with each other.
