An Alert Pup!

Even when Barnum was a tiny puppy, I knew he had great potential for sound alert. He’s very sensitive to, and inquisitive about, noises. He also seems to have terrific hearing, which is a nice change of pace. (Gadget, I believe, was hard of hearing, and I think Jersey’s hearing was fine, but she just didn’t care much about sounds that were not food related.)

Why, as a hearing person, do I want Barnum to respond to certain sounds?

  • To alert me to sounds, such as timers and alarms, that I don’t hear because I’ve fallen asleep;
  • To alert me to sounds that I’ve forgotten I heard (timers and alarms), because of my cognitive impairment and memory problems; and
  • To make him faster and more effective at retrieving the telephone when it is ringing, and I can’t get to it.

My plan was to train Barnum to perform the sound alerts that Gadget did, primarily alerting me to the stove timer going off. This was a very difficult skill for Gadget to master; it took several months of intensive training. Nonetheless, I’ve been confident that Barnum would learn this alert more solidly and quickly because he is much more attuned to sounds than Gadget was, and because I am a better trainer now.

I trained Gadget to alert to the stove timer as part of my effort to stop burning my meals to cinders.

However, a couple of years later, this skill became useful for an unexpected reason: I got Lyme disease, and for many months, I had to take antibiotics at 12-hour intervals. It is very rare for me to be awake and coherent for both ends of a 12-hour shift, every day.

Thus, Gadget became my medicine reminder. After taking my dose, I’d reset the timer for 12 hours. If I happened to be asleep when it went off, Gadget would hear it, open my bedroom door, run to get his orange squeaky “alert balls” and bring one back and wake me up with it. (You can see a [poor] demonstration of this skill in the second video in this previous post.)

Barnum Takes the (Sound) Stage

In a very laid-back way, I have been encouraging Barnum to pay attention to sounds ever since he was a little puppy. The sounds I’ve focused on are the ring of the cordless phone and the beeping of two timers: the stove timer and my digital “personal timer” (which lives on my overbed table, and which I use to remind myself of phone appointments or other happenings I’m likely to forget).

By “laid back,” I mean that I hadn’t set up training sessions to work on this. I just took advantage of opportunities that presented themselves (also known as “capturing,” in clicker parlance). In other words, if Barnum and I happened to be near the cordless phone when it rang, I’d  act excited, and say, “It’s the phone!” Then I’d toss him a treat. If he oriented to the phone (i.e., if he looked at or moved toward the phone), that definitely earned a click/treat.

I used the same approach with the kitchen timer.

I didn’t really consider this training; more like “pre-training.” My primary goal was to prevent Barnum from becoming so acclimated to these sounds that he stopped noticing them when the “real” training began.

A few weeks ago, because it was convenient, I decided to get slightly more proactive with building a foundation for sound alerts. Whenever my personal timer went off, I’d toss Barnum a high-value treat. He soon was leaping up and running over whenever he heard my timer, and I thought, “Huh, I should probably do something useful with this behavior.”

This urge was strengthened when we were in the living room a couple of weeks ago, and the phone rang. Barnum turned toward the phone and barked at it! I never taught him to do that. I was pleased and impressed.

Barnum Responds to Infusion Pump Alarm!

That’s when I realized I could — and should — train Barnum to be my infusion-pump alarm back-up.

Those of you with chronic Lyme disease or who have had chemotherapy or other long-term intravenous medication are probably familiar with the ins and outs of infusion pumps. For those who aren’t, here’s a crash course in home-infusion therapy, and how a service dog can be of use.

First, there’s the PICC line. PICC stands for “peripherally inserted central catheter.” It’s a flexible little tube that goes inside a vein from your upper arm to your heart, delivering medications into your bloodstream much more efficiently than by any other method. (Here’s a site on PICCs if you want more information.)

Closeup of Sharons arm with PICC line coming out of biceps

I know it looks weird, but it doesn't hurt, and I'm quite used to it after 18 months.

[Photo description: Sharon’s inner upper arm and elbow with PICC line and dressing. The PICC line is a very thin white plastic tube coming out of a round “biopatch” — which looks like a nickel-sized styrofoam disk — in Sharon’s biceps. The biopatch covers the entry site of the line. Several steri-strips hold the biopatch and line in place. A hypoallergenic clear sterile dressing that looks like a piece of plastic covers the PICC area, with two pieces of hypoallergenic medical tape holding down the dressing. The line emerges from under the dressing to a red clasp, which is opened when flushing or infusing. A white plastic cap connects the line to a clear extension tube, which is a port into which syringes of medication or saline can be inserted for infusing or flushing.]

The above photo description tells you the rest of what you need to know (or maybe more than you wanted to know!). The only unusual thing others with PICCs might notice is that this is not a typical PICC dressing. Most of the stuff normally used for cleaning and dressing PICC sites makes my skin erupt and blister in a nasty way. (Thanks, MCS!)

At any rate, I do two infusions a day, 12 hours apart.

To do an infusion, I have to clean the port with a disinfectant, then flush my line with saline (the smaller white syringe in the picture below). Then I hook up an extension tube between the antibiotic and my PICC line. Infusing the antibiotic (the really big syringe attached to the pump in the picture below) takes about 45 minutes. The pump ensures that all the medicine goes in at a slow, steady rate.

When the tube of antibiotic is empty, the pump alarm sounds, which is a loud, grating, “Beep, beep, beep,” and a red light flashes. The I unhook my line, clean it, and flush it with saline again, and finally with heparin (the yellow syringe below).

Infusion Pump with extension tubing, saline flush, heparin flush

The red light on the pump indicates the alarm is going off, and it's time to unhook the extension tubing and flush my PICC line.

[Photo description: two 12 millilitre syringes, without needles, one yellow, one white, lie on a red background next to a 60 millilitre syringe which is attached to a rectangular, brown Bard pump, about nine inches long and three inches wide. Extension tubing comes out of the big syringe. A red light is on at the bottom of the pump, next to the word, “Alarm.”]

Rather, that’s what’s supposed to happen, and most of the time, it does. However, on occasion, I fall asleep while I’m infusing. When this occurs, I wake up many hours later, my line still connected to the pump, the flushes laying nearby, unused. Tellingly, the pump switch has magically been moved from “Alarm” to “Off”!

Actually, I’m pretty sure no magic is involved. The only reasonable explanation is that I wake up just enough to switch the alarm off and then fall immediately back to asleep. I have no idea how long the pump is alarming before I turn it off in my mostly unconscious state. In the morning, I almost never remember waking up and turning off the alarm.

This is less than ideal! The line should really be flushed immediately after infusing. Also, if I were to ever startle awake and move quickly, I could potentially pull the line out of place (particularly because my dressing does not allow for as secure an attachment as is standard practice for PICCs).

Sharon Falls Asleep while Infusing

Exciting reenactment: I fall asleep while infusing.

[Photo description: Sharon lies asleep in bed, propped up with pillows. She wears gray sweatpants and a purple sweatshirt over a pink nightshirt. On her left side the sweatshirt has been pulled up to expose her upper arm, where the PICC dressing and tubing are visible, attached by a long, thin, clear line to the infusion pump, which rests against Sharon’s thigh. On her legs, the saline and heparin flushes lie, waiting to be used after the infusion is over.]

I realized that a really useful skill, and one that would probably not be hard to teach, would be to train Barnum to wake me when my infusion pump goes off.

I started out with classical conditioning, just tossing Barnum one of his favorite treats each time the alarm went off. He made the connection very quickly — within a few days.

Then I moved to operant conditioning, shaping Barnum’s behavior. Once he showed any reaction to the pump alarm, I clicked for the response. As always when shaping, I started with whatever small behavior he offered, such as cocking his ear toward the sound, or turning his head toward it, or just looking up from a nap. Eventually I withheld the click until he was trotting over.

My plan had been to keep upping the ante to get him to jump on the bed, nudge me, etc., until I woke and reward him.

Sunday morning was the first, and only, time I cued a behavior — jumping on the bed (“Paws up!”) — before clicking and tossing the treat.

That night, as usual, I flushed with saline, connected the pump and began infusing. I had my clicker and Barnum’s special treat ready for when the alarm went off. About half an hour into the infusion, I got the suddenly sleepy, struggling-to-stay-awake feeling. I thought that knowing I had to be awake to capture and click Barnum’s response to the alarm would keep me awake.

I was dreaming — literally!

The next thing I knew, I was awakened. All was confusion. The bed was moving, and I didn’t know why. There was a strange noise.

I struggled to orient myself.

The first thing that registered was that Barnum was on my bed, panting and smiling at me. Then, the strange sound resolved, as well — it was the infusion pump alarm.

Amazing dog! Barnum had jumped on the bed of his own accord and woken me when the alarm went off!

I praised him as I scrambled for the clicker, and tossed him his prized treat. I continued to praise effusively, tossing a large handful of other treats I happened to have in my bed.

Barnum "Paws Up" on Bed
I’m here! Wake up! I want my treat!
[Photo description: Barnum, a shaggy black brindle bouvier, with only one eye peeking out from under his hair, has jumped partway onto the bed, with his front legs and chest resting on a dark raspberry-colored comforter. He looks relaxed and slightly expectant. Sharon’s powerchair is visible in the background.]

I was so excited! With Gadget, I had had to spend weeks just on feigning sleep during timer-alert sessions. I will plan to train this way with Barnum — pretending to be asleep when the alarm goes off. He’ll have to really work for that treat by jumping on the bed, nudging me, licking me, etc.

However, I had thought that if I actually did fall asleep while Barnum was at this stage of training, he would have popped up from the floor, looked for his treat, and when he didn’t get it — when I just lay there, conked out — he would give up and go back to bed.

Instead, Barnum made a mental leap that required not just thinking (i.e., problem solving), but self-confidence, too.

I believe our recent focus on lots of free-shaping sessions (as I described in a previous post) led to this breakthrough.

Now, saying that Barnum is a service-dog-in-training feels more legitimate. The pay-off for our training is no longer just fun or incremental steps in increased obedience and communication; the real-world application of practical service skills is becoming apparent.

Barnum’s increased exuberance and eagerness to offer behavior in the absence of a cue or other encouragement from me is thrilling!

An Alert Pup . . . and a Groggy Human

Any assistance dog partner will tell you that there are two members of the team, and both have to do their jobs. Sunday night, Barnum rose to the occasion, while I fell asleep on the job!

After I shut off the alarm and finished fussing over Barnum, I turned my attention to unwrapping my saline and heparin flushes and looking for my sterile wipes and line caps — the supplies necessary to finish the infusion process. . . . The next thing I knew, it was morning, my left arm was still out of my shirt sleeve, and my PICC line was stretched down to the pump!

These are the times when both the pros and cons of being a disabled person training my own service dog come into sharp focus.

On the down side, I had underestimated my functionality. I had thought that being awakened by Barnum, and being forced to interact with him, would keep me lively enough to finish the infusion process. I had not factored in how my cognitive impairment (in this case, memory and concentration issues) would intersect with my sleep disorders. I had not given enough weight to how hard it is for me to “stay on task” when my body and brain switch from “nothing you do will allow you to fall asleep” to “nothing you do will allow you to stay awake”!

On the upside, I now know that I have to build in back-up systems after the initial wake-up, to keep me awake, or to wake me repeatedly, until I finish flushing my line. This is perhaps the biggest bonus of partner-training: I can trouble-shoot and adjust skills as we go along, because nobody knows my disabilities better than I do.

Another bonus to doing all this practice with him is that I am also training myself.

This was the unexpected perk to training Gadget to alert me to the oven timer. People who don’t have brain injury often don’t understand that their suggestions of seemingly straightforward solutions to memory problems, such as “write a reminder note” or “set a timer” require the cognitively impaired person to remember to write the note or set the timer, and also to remember where the note is, to remember what the timer going off means, or to remember to jump up the instant the timer goes off and go do the thing the timer is reminding one of. I write notes all the time to remind myself of what to do, and then I misplace and forget about the existence of the note!

Indeed, before training the memory alert with Gadget, the biggest impediments to using a timer to prevent me from burning my food had been:

  1. Forgetting to set the timer in the first place;
  2. If I did set the timer, not responding the moment the timer went off (e.g., if I was writing an email, I’d think, “I’ll just finish this sentence,” and then forget that the timer ever went off) and keep on keyboarding; and
  3. If I did get up to go to the stove as soon as I heard the timer, I usually became distracted by something on the way (even though the stove was only a few feet from my desk), and forget the original reason for getting up.

However, when I worked for months on training a complex timer alert with Gadget, I spent a lot of time focused on setting the timer, remembering to keep clicker and treats handy to respond when the timer went off, etc.  It became a form of cognitive-behavioral therapy for me. The end result was that I was much more likely to remember to set the timer when I put something on to cook, and I was also more likely to respond to it when it went off, sometimes because Gadget alerted me, but sometimes simply because my mind was better trained to hone in on the timer.

Thus, I’ve decided that the best way to address this added dimension of the infusion pump alarm with Barnum is to train us both to following this protocol:

  1. When the pump goes off, Barnum bugs me (jumps on the bed, nudges me, licks me, etc.), until I wake up.
  2. The instant I wake up, I hit my personal timer (set for six or seven minutes).
  3. I turn off the infusion alarm, and reward Barnum for having alerted me.
  4. I attempt to stay awake to unhook, infuse, and put things away.
  5. However, if I do fall asleep before I’m done, the other timer will go off, and Barnum will alert to that, leading us to repeat steps one through four.
  6. If I do get my line taken care of, and the timer goes off before I’m done, I reward Barnum for alerting to it anyway.

In other words, I’ve had to add a step. Or a step that repeats itself. So, it’s really just more of the same. Which is sort of the essence of clicker training: once you build a foundation, it’s all variations on a theme, requiring flexibility, creativity, and knowing the rules by which you’re playing.

This is also the essence of a service dog partnership.

And of life.

I’m so proud of my dog! And I’m not feeling too bad about myself, either. Nice change of pace.

– Sharon, the muse of Gadget (I’d have done better with the timer alert if you’d trained it better!), and Barnum (What’s that sound?!) Medical-alert-dog-in-the-making!

    I’m continually amazed at what you’ve been able to train your pups to do. So glad that Barnum is learning quickly and helping out. My cat is very good at waking me up, but only when she needs something!

  2. 2 Sharon Wachsler February 10, 2011 at 10:47 am

    Hi Kim,

    Thank you! Yeah, I’m wondering if other Lymies might have this problem and find this a useful skill.

    I’ve had plenty of dogs (and cats), including Barnum and Gadget, who were good at waking me for no good reason (to me) as well!

  3. 3 Starre February 10, 2011 at 12:28 pm

    Thank you for the paragraph about “just write a note”.
    I was repeatedly told that that was a solution to all my problems and I was totally overblowing everything by wanting a dog to help.

  4. 4 Sharon Wachsler February 10, 2011 at 1:04 pm

    Starre,

    Thank you so much for this comment! You’re welcome! I hear your pain!

    In fact:

    1. WHILE I was in the process of writing this post, and telling my partner (who is extremely familiar with my cognitive issues) that I am having a lot of trouble remembering whether I have done a daily injection that is a new part of my routine, she said to me, “There’s this thing called paper, and another thing called a pen. . . .” And I wanted to yell at her!

    Instead, I read her the paragraph you mentioned!

    2. I once wrote a short story from the perspective of someone with brain injury, trying to convey what it’s like to have fractured thinking, and when I got critique on it, people said, “Why doesn’t she just write a note?”

    I thought, “Aha! I have clearly not achieved my goal; the complexity is missing.”

    I actually wrote someone telling the narrator to write a note into the story.

    I think memory issues are very difficult for people with fully functional brains to wrap their (fully functional) minds around! Especially if you, like me, SEEM so mentally “with it” to people who don’t see how pervasive, frequent, or inconsistent the problems can be.

    I am so very glad Barnum is growing into a handsome and smart young pup. He is doing so well Great JOB!!!

  6. 6 Laura February 10, 2011 at 4:56 pm

    Yea!!!! Go Barnum 🙂 Go Sharon! Wow, what an amazing leap! All of the time, effort, frustration and faith (for the both of you) is becoming totally worth it 🙂 I’ve been lucky to have a few of those breakthrough moments with Yuki, our deaf pit pup, when she ‘gets’ a hand signal and responds appropriately, especially the first time, it’s a great feeling 🙂

    What a brilliant pup! Yay Barnum!

    I sometimes have memory and concentration problems and I used to write myself notes on my cell phone, which I could set to display on the main screen. (Now that I have an iPhone, I use the calendar to send push alerts.) The thing is, on that old cell phone, if no one called or texted me, I’d forget to look at it and wouldn’t see the reminder. The note doesn’t work if you forget to look at it!

    On a somewhat random note, I’m wondering what kind of tape you use? I have ISSUES with adhesives, and thus far I’ve only been able to tolerate Transpore tape – it’s one of the hypoallergenics, clear plastic. They’ve tried multiple brands of paper tape, silk tape, and another kind of plastic tape, all of which gave me painful rashes.

    Those damn clear tape square thingies they use over IV sites? Yeah, I’m allergic to them too. But because it’s not considered a severe reaction, they insist on using them, even though it’ll give me a rash that extends about 1/4 to 1/2 inch farther out than the tape itself. Bleh.

    I totally have issues with adhesives. The replacement we use instead of Tegaderm is called IV3000. I found out about it from other Lymies with MCS and really sensitive skin.

    I also can’t use chloraprep, which is the antibacterial wash they normally use, so we alcohol wipes. It’s only recently that I can tolerate alcohol enough to do this. I still react to it somewhat, but it’s OK.

    The steristrips I do quite well with. I’m not sure what they’re made of. They’re probably hard to see in the picture. They come three to a package, and they’re very thin and small and lightweight. They are holding down the biopatch and the line.

    The two white strips that look like foam come from the package that contains the statlock, which we don’t use. I can’t have those touching my skin at all, or it turns red, bubbles, and opens up. Lovely.

    We put those on top of the IV3000, to try to hold it down a little better. However, even having that over top of the IV3000, it does make me itch, and usually by the end of the week, my skin has opened up some.

    Actually, the entire dressing, esp the alcohol and steristrips, makes me itch and can cause my skin to open somewhat (“excoriation” is what the nurse calls it), but as you can see from the picture, most of the time, by using these measure and moving things around a lot, we keep my skin in very good shape.

    Before we figured this out, my nurse said my skin/reaction was the worst she’d ever seen. Sometimes it’s still itchy enough that I will actually pull the dressing off in my sleep, from the itching. Now she uses IV 3000 for several of her patients because so many react badly to tegaderm. We tried several brands before we got to this one.

    Hope this helps! I see a surgeon Tuesday about switching to a port….

    P.S. I can’t tolerate any tapes, including band-aids, as well. I totally can’t tolerate transpore. I can tolerate paper tape for short periods of time, but that’s it.
    Transpore’s one of the many parts of my dressing change kit we don’t use. It is, however, useful for taping together freezer paper when we rewrap Barnum’s meat for the freezer. Hee hee.
