Cuff Inflation and
Pressure Protection
The maximum allowable cuff pressure is 300 mmHg adult mode (150
mmHg in neonate mode). Adult mode cuff pressure is allowed to
remain above 15 mmHg for a maximum of 180 seconds. Neonatal
mode cuff pressure is allowed to remain above 5 mmHg for a
maximum of 90 seconds.
The monitor automatically deflates the cuff if the time limit is violated.
The monitor contains hardware protection for overpressure
conditions, pressure transducer failures, or microprocessor and pump
control circuit failures.
