Norco was the respiratory care supplier my nursing agency recommended. A call was made to an RT at Norco by the name of Rebecca and she called back. An appointment was made but being canceled due to inclement weather it was rescheduled a week on 12/1/10. Rebecca came with a Trilogy 100, a compact, blue box for me to try. First she went through some paperwork which involved my medical supplies. Then tubing was hooked up and Rebecca dialed in similar vent settings as my LP10. The sensitivity setting on the Trilogy was different than my LP10 or LTV 800. It had no negative range only positive—from 1 to 9. Rebecca started me off at 1, but it didn’t seem right until 9 where I could trigger a breath. I wasn’t able to trigger as often as I desired though. The alternative would be an newer LTV model which is less user-friendly and less battery power. Weighing the pros and cons, the Trilogy fits into my lifestyle.
