Self tests (SST and EST)
SECTION
All 700 Series Ventilators include these built-in self tests:
• Short self test (SST) is a short (about 2 to 3 minutes) and simple
sequence of tests that verifies proper ventilator operation, checks
the ventilator breathing circuit for leaks, and measures the circuit
compliance. Power on self test (POST) is part of SST.
• Extended self test (EST) is a thorough test of the operational
integrity of the ventilator, both the electronics and the
pneumatics. POST and SST are part of EST.
Warning
• Before running SST or EST, you must disconnect the
ventilator from the patient. Running SST or EST while the
ventilator is connected to the patient can injure the patient.
• A fault identified in SST or EST indicates that the ventilator or
an associated component is defective. A defective ventilator
or associated component should be repaired before the
ventilator is returned to service, unless it can be determined
with certainty that the defect cannot create a hazard for the
patient, or add to the risks which may arise from other
hazards.
