SeQual Eclipse 3 Portable Oxygen Concentrator Secrets

In: SeQual Eclpse

10 Feb 2012

SeQual Eclipse 3 Portable Oxygen Concentrators have many built in advantages that are secret to many SeQual Eclipse 3 owners.

Much like the protective cover and keeping this SeQual Eclipse 3 protected from the environment, if you only look inside a SeQual Eclipse 3 you will find features other portable oxygen concentrators only dream of.

One hidden gem of the SeQual Eclipse 3 portable oxygen concentrator is the Pulse sensitivity setting.

The Pulse Settings on the SeQual Eclipse 3 has a range from 1.0 to 6.0 and three additional doses or setting equivalent to 128mL, 160mL, and 192mL

Typically the criteria to trigger a pulse of oxygen is a drop in cannula pressure below the trigger point, typically 0.15-0.45 cm of H20 of negative pressure.  Meaning a breath through the cannula that was at least 0.15-0.45 cm of H20.  Additionally, the E3 has another criteria for the pulse to be triggered, and that is at least 1.25 seconds have passed since the last pulse began.  Assuming the 2 Trigger Criteria for a pulse have been met, the SeQual Eclipse 3 will deliver the dose of oxygen.

The SeQual Eclipse 3 is always  monitoring for breath detection, even when the unit is running in continuous mode.  While in Pulse Mode, if the SeQual Eclipse 3 detects no breath after 15 seconds, the SeQual Eclipse 3 switches to delivering continuous flow oxygen at the last setting.  After another 15 seconds have passed the SeQual Eclipse 3 will again monitor the patient for a breath.  If a breath was detected, the SeQual Eclipse 3 will switch back to Pulse Dose mode.  The SeQual Eclipse 3 will continue the operation until a breath is detected.  This is a software improvement over first generation Eclipses that would change to continuous flow, but never change back.

The SeQual Eclipse 3 has the ability to change the sensitivity of the Pulse Trigger Criteria.  Only the LifeChoice Portable Oxygen Concentrator has a similar ability in the Sleep / Activity Mode settings.  The SeQual Eclipse 3 can have the Trigger Sensitivity adjusted to the individual patient.

With a SeQual Eclipse 3 the patient can adjust the Pulse Trigger Sensitivity to best suit his respiratory efforts.  By default the PS or Pulse Sensitivity setting on the SeQual Eclipse 3 is 2.

The Choices for SeQual Eclipse 3 Pulse Sensitivity settings are 1, 2, and 3.  Setting 1 being the MOST SENSITIVE and setting 3 being the LEAST SENSITIVE.

By depressing the No Smoking button on the control panel of the SeQual Eclipse 3, you access a secret operations area, the Provider Mode Area where you will find the PS, or Pulse Sensitivity settings.


Access the SeQual Eclipse 3 secret button by depressing the Cigarette with the circle and line through it.

Additionally, when depressing the secret button or Provider Mode button for the SeQual Eclipse 3, you will have access to other useful information.  While most of this information is very useful to the Provider servicing your SeQual Eclipse 3, it does not hurt to know how many hours are on the unit.

In another post, we will go over the other functions included in the secret area of your SeQual Eclipse 3, they include:

  • Alarm Code or codes present on the machine – a great tool for remote diagnosis of your SeQual Eclipse 3.
  • Pulse Sensitivity
  • Hours the SeQual Eclipse 3 has been operated, a great tool to identify the need to a PM
  • The status of the little known but extremely important internal 9 volt battery.
  • The Bolus Rise time (more on that later)
  • The software version of the E3 control board
  • The software version of the E3 power management board.
Now that you have read this post, you know more about the SeQual Eclipse 3 than most users!

004 and 008 on start up are normal operation.
The machine is warming up, and the lights should go out.
004, oxygen below 70% purity
008, oxygen between 70 and 85% purity

Are you getting an error code that needs explanation?
Otherwise, at the bottom of the article the related functions of the ‘secret button’ are listed.

Is there a section you would like some detail with?

the general alarm on my Life Choice O2 generator is firing continously. The unot has not been used very long tho I bought it secound hand. Cannot afford the $1,400 fee to have it “fixed”. Please help me to reset it by myself. Do not have any insuranceand feel that this is an insurance scam and if instructed how can undo the alarm myself.
Thank you !

I wish it were a simple ‘reset’ button. On the Lifechoice, what is happening when the alarm goes continuously, is the unit is not producing oxygen above the therapeutic level. There is no resetting it. The unit will need new sieve beds and as long as you are there, you’ll want to replace the internal battery. The software will be upgraded,the sieve beds will get new lining and you’ll most likely double the life out of the new beds.

To get that unit refurbished is $900. That is software, sieve, and internal battery.

number 1 phillips, remove the battery, use shock protection for the equipment inside.
