Trilogy 100 - dropping O2 levels

Post by Heidi » Mon Feb 01, 2016 4:28 pm

I have a Trilogy 100 for COPD, my oxygen level dropped to 60 on my oxi pulse on another night tested it again and it starts dropping after 15 minutes of wearing the mask, a friend watching. It's not safe to sleep with. I want to wear and need the benefits but, telling the RT did no good and my Doctor doesn't know if the settings are right. The original settings came from the hospital, I had another machine same settings and it did the same thing alarms going off and dropped oxygen, the RT came with a Trilogy 100 same settings, alarms turned off. This RT does not know much on this Trilogy 100.

Can anyone help me find an answer or give me ideas what to do?

I can post the settings if you need them.

Thanks!

I suggest you PM "Madalot" who uses a Trilogy, tho' have no idea if it's the same one.

You mention O2 pulse, your O2 machine MUST BE full flow, not pulse. You need a real doctor, soon not later. Jim

Thank-you! Julie so much I will PM "Madalot"


Jim, I do use a full flow oxygen concentrator, the oxi pulse is a finger pulse oximeter that you clip on your finger to check your oxygen level.

Hi Madalot, here are settings:

Mode AVAPS-AE
AVAPS rate 3.0 cm H20
Tidal Volume 440 ML
Maximum Pressure 20.0 cm H20
Pressure support Max 12.0 cm H20
Pressure support Min 5.0 cm H20
EPAP Max pressure 10.0 cm H20
EPAP Min pressure 5.0 cm H20
Breath rate Auto
Trigger Type Auto-Trak (Sensitive)
Rise Time 3
Ramp length Off
Circuit disconnect alarm Off
Apnea alarm Off
Low VTE alarm Off
High VTE alarm Off
Low minute ventilation alarm Off
High minute ventilation alarm Off
Low Respiratory rate alarm 4 BPM
High Respiratory rate alarm Off


This is everything, I did not turn alarms off RT set it up this way. I weigh about 95lbs so I am concerned about the Tidal Volume.
A different RT told me that the machine could be knocking out my drive to breathe therefore, causing the oxygen to drop and possibly recirculating CO2 back into my body, I stopped wearing the machine.

Thank-you!

I'm far from an expert on these types of machines, but what I do know about VAPS, the tidal volume needed is calculated more from height than weight, since weight doesn't affect how long your airway is, whereas height does. so there's anatomical deadspace to be calculated (distance from lungs to mouth, as I understand it).

just adding my 1 cents (I wouldn't even call it 2 cents worth )

I think you need to have your RT download the data from your card into Direct View. That would be the first step I would take before proceeding any further.

I had 2 horrific strokes, is this AVAPS machine better for central apnea, mixed apnea than the Bipap ASV/autosv? I've been trying the auto sv Phillips and I never got restful sleep. On sleepyhead I had a lot of clear airway apnea events on the ASV and sometimes hypopneas and rarely an OSA event. Maybe the problem was I was getting 0.1% stage 3/4 sleep.

OP, you may want to lower your rise time to 100 or 150ms. And lower your trigger sensitivity to Auto-track, not sensitive. What is the inspiratory time set to for your backup rate?

How tall are you? Match your height and gender with 8 mL/kg and put that value in as your target tidal volume. http://www.ardsnet.org/files/pbwtables_2005-02-02.pdf

My mom uses the same trilogy and her oxygen level does the same thing while wearing it. She keeps her oxygen in her nose and just snugs the mask on over it and that works for her
