Why can't I set the desired pressure on my SLE Medical Equipment CPAP?
- N
  Nicholas PopeAug 20, 2025
  If you're unable to set the desired pressure on your SLE Medical Equipment CPAP, it might be due to: * A faulty patient circuit. Try replacing the circuit. * An incorrectly assembled patient circuit. Reassemble it according to the drawing supplied with the circuit. * An exhalation block located incorrectly. Relocate the block assembly. * The regulator cap being in the LOCKED position. Pull the regulator cap out to release it from the locked status. * A seized regulator control or blocked CPAP nozzle. Consult an SLE trained Engineer.

What should I do if I am unable to set desired pressure for peak insp pressure on SLE 2000?
- C
  Christy BoydAug 25, 2025
  If you're unable to set the desired pressure for peak inspiratory pressure on your SLE Medical Equipment, consider the following: * Faulty patient circuit: Replace the circuit. * Incorrectly assembled patient circuit: Reassemble as per the drawing provided with the circuit. * Exhalation block located incorrectly: Relocate the block assembly. * Regulator cap in LOCKED position: Pull the regulator cap out to release it. * High alarm condition: Reset alarm setting. * Water in proximal airway pressure tubing: Drain the tube. * Seized regulator control or blocked Insp. nozzle: Consult an SLE trained Engineer.

What to do if I get a cycle fail alarm on my SLE 2000?
- K
  Kevin LyonsAug 27, 2025
  If you receive a cycle fail alarm (audible & visual) on your SLE Medical Equipment, check the following: * Incorrect PIP alarm setting: Readjust the PIP alarm to INSp pressure. * Proximal Airway line disconnected: Check the sent vent pressure and reconnect the tubing. * Proximal Airway blocked with water: Reconnect the tubing. * Solenoid failure: Consult the Service Manual or an SLE trained Engineer.

Why is the blender alarm sounding on my SLE 2000 Medical Equipment when both gases are connected?
- C
  Chelsea ShawAug 30, 2025
  If the blender alarm is sounding on your SLE Medical Equipment when both gases are connected, it could be due to: * Alarm shuttle sticking: Remove both gases from the supply and reconnect O first. If that doesn't work, disconnect and then connect the Air first. * Air or O gas failure: Repair gas supply. * Air/O differential pressure exceeded: Consult an SLE trained Engineer if the alarm persists. Also, check that the difference in pressure between the two gases is less than 30 PSI.

How do I resolve a high alarm on my SLE 2000?
- H
  heatherhillSep 3, 2025
  If you're experiencing a high alarm (audible & visual) on your SLE Medical Equipment, it may be due to an incorrect PIP alarm setting. Try readjusting the alarm to INSP PRESSURE or readjust the INSP Pressure regulator.

What causes varying pressures in SLE Medical Equipment?
- R
  Ryan DaySep 6, 2025
  Varying pressures in SLE Medical Equipment can be caused by blocked or water-logged filters. Replace the filters to resolve this issue.

Why does the waveform have a slow rise time on my SLE Medical Equipment?
- D
  Dr. Anthony RuizSep 10, 2025
  If the waveform has a slow rise time on your SLE Medical Equipment, it could be due to water in the proximal airway line. Replace the patient circuit.
