Table 2-11. Inspiratory lockout troubleshooting.
(e) Slowly rotate the inspiratory time-limit stem counterclockwise until
an inspiratory lockout occurs at 3 seconds (plus or minus 0.2 second). Begin your timing
at the start of an inspiratory cycle and stop timing when the unit locks out, not at the
sound of the alarm.
(f) Confirm a 3 second lockout (plus or minus 0.2 second) and then
mark the end of the inspiratory time-limit stem at 12 o'clock with a pencil.
(g) Push the reset button and rotate the inspiratory time-limit stem
clockwise for a 5.5- to 6.5-second lockout time.
