Medical terminology, especially abbreviations can be confusing especially when you are already stressed out from dealing with a sick family member or pet. The commonly used ones are TID which is three times daily, QID which is four times a day and QD which is once every day although it was being abandoned in favor of Qday as too many med errors were possible mistaking QD for QID. QHS is at bedtime and QAM which is every morning. Usually a script is written or in the case of dosing animals, the directions appear on the labels of the meds and should tell you dosage, route, time and frequency. If you buy medicine for your birds, like most of us do at the local feed store or on line, you need to familiarize yourself with the terminology so you can treat your beloved birds safely. Once you do congratulations, you are a barnyard or backyard nurse.
For your reference:
I graduated from nurses training in 1975 at the advent of the technology boom that ushered in the new era of medicine. We were taught to use our education, our senses and common sense when practicing our art and you have to do the same when dealing with sick or injured animals. Like small children, they cannot tell you where it hurts or how they feel sick. It's a puzzle that you have to sort out and put together.
Frankly, y'all amaze me at what you will attempt in order to save one small feathered life with only the knowledge, experience and advice that you can glean off the Internet and forums like BYC, and I salute each and every one of you.
To the OP, I fear for your feathered friend and hope you can find out what is wrong with her and buy her some more time. There is a saying in medicine that when God puts his hand on a person's right shoulder you have no choice but to move yours from the left.
