          the oxygen line and the other for connection to a saline
          bag. The pressure generated depends upon the flow rate
          of oxygen (9 L/min‑4 PSI, 11 L/min‑6 PSI, 13 L/min‑9 PSI,
          15 L/min‑12 PSI). All patients tolerated the JFT procedure

          moist saline dressing was done. In Group  1, only JFT
