Day 50 7/11/13 (More nebulizers, air compressors, cleaning filters with syringes, smokin’ out mosquitoes, meeting SILAIS and buying baked goods)

Today was another of one of the classic 6 AM days (I actually thought about getting up early as I had the energy, but then all of a sudden, BAM it was 5 minutes to 7 (well I guess it worked out)). Anyways breakfast was pretty good and we had this epic cheesy bread with B&R, other cheese and eggs and salami and banana coffee smoothie thing. We arrived at work actually decently early today (at like 8:20 AM) and started pretty much right away. Dan took the tape off the IV stand and we got the other neb from the emergency room to take another look at it. 

What the flow from the neb looks like

One of the first projects was to work on the nebulizer from yesterday and today. We opened them up and looked at the motor (which seemed fine), so we just put it back together (after cleaning the diaphragm a bit). I then thought about checking the other air side of the external airport and inlet (which happened to have a filter that looked horrible) (so the obvious choice was to clean the filter). This involved taking one of the syringes we bought and filling it with water (without the needle (although we later used the needle)) and pushing the water through the filter to try and remove the dirt (this seemed to work a tad bit and definitely helped clean the filter). This wasn’t the most effective strategy in the world (but we didn’t have any alternative (and no new filters)). 

Working on cleaning the filter (got to practice my best liberating air from syringes technique)

The inside of the neb (so annoying to put back together)

After we eventually finished this process quite a time later (we had to wait for the filters to dry) then we could finally re-install them. We at one point were displaced from our workshop temporarily as there was a SILAIS worker walking around with what looked like an M60 (except that it spat out white smoke instead of bullets (this smoking gun still looked absolutely beast)). Anyways he was walking around all the houses in the area and buildings and smoking them out (to apparently kill or drive away the mosquitos (as this is to stop the spread of Dengue (as this has been a huge problem with trucks coming from Honduras, so they have been fumigating the trucks with this smoke))). It was a pretty legit exercise.

After leaving the nebulizer filters to dry, Dan and took apart this one air compressor from the pediatric ward (that we’d gotten to fix) and opened up the inside (and exposed the commutator which isn’t great for motor performance, but we wanted to oil the bearings). When we looked at the bearing, we immediately realized why the compressor (O2 concentrator wasn’t working); the bearing was rusted solid (basically this small ring of rust had formed around the inner edge of the bearing and the shaft protruding from the bearing was immobile). So much for that having a chance at turning! Anyways we decided it wasn’t worth working on that and instead turned to another older model we found in the shed (which showed promise as it not only turned on, but actually worked passably without much maintenance). So I started working on cleaning the older model (which was caked in dust). When I got to the reed valves, the scene looked especially grim; with tons of tiny beads of corrosion sitting all around the rubber diaphragm (O.o). 

Look at all the corrosion (O.o)

It was okay though, because Dan had cleaned the reed valves and top piece for another compressor that refused to function despite extensive cleaning (so I just swapped the top and reed valves part over on the compressors (which happened to conveniently be the same model) and continued on my cleaning). I had to clean all sorts of gunk and caked dust and spider webs out of the air intake and fan areas and I took off the fan and oiled all the bearings and got that shaft spinning quite well (not as good as if there were a Bones Swiss bearing inside, but it was much much better than how it had rolled before).

Replacing the power cord on the compressor (blue twist terminals FTW!)

After that I pretty much packed up the motor (although I kept forgetting parts and had to take the housing off several times (once for some parts behind a fan and another time for not tightening bolts on the iron core and with the windings around it)). I also replaced the power cord on the motor with a shortened one from another and added in my favorite twist terminals to make the necessary power connections before closing the motor up. After all of that work it was around lunch time (as Dan and I had been working in parallel on two different compressors (as two had cropped up (the dead one and another that showed promise from the pediatric ward (the pediatric ward was interesting and had an oxygen concentrator, a pulse oximeter, an aspirator, a nebulizer, a hot plate and the air compressor/more manual oxygen concentrator)) and we both tested our compressors. Dan’s happened to not function exactly as he had expected (with not even running), but that was due to the compressor just needing to be opened up and closed again (simple and it worked really well after that). Mine worked decently from the first time without needing to open it up again (as I had already done that several times prior to testing). Anyways we went out to find some lunch, but we ran into Barney and the Engineer who were getting ready to head to the normal lunch spot. We decided to join them for lunch, but first they were loading the non-functioning ultrasound into the back of this dude’s truck (the master of electronics and software). Barney is paying them to put in a new power supply I think (which costs like $6K or something wicked expensive similar (O.o) (that’s why Barney makes the big dollars in repairs)). Lunch was pretty filling and was this chopped up meat (in tiny tiny chunks) with B&R and semi-soft plantains and this pink drank that had particulates (looked like the oatmeal stuff) (think it might have been pink Tang).

            After lunch was pretty chill. Basically went back and put the necessary air fittings on the compressors (pressure gauge, regulator and rubber tube adaptor in a prefitted piece). I then tested my compressor again and I was getting close to 30 psi (max positive pressure) out of that bad boy (pretty good for a compressor that’s smaller than the volume enclosed by my open laptop (imagine lines up from the keyboard and form a rectangular box (compressor is like maybe 12” x 9” x 10”))). I tried to get all the feet back on one of the compressors, but the screw was not level so I tried (with Popo’s help to screw it a bit more into the base, which only ended up breaking the screw head off (-.- // rage (now I have to drill it out and put a new bolt in))). After that Dan worked a bit more on getting the filters cleaned for the two nebulizers (nebuliers more like it because they don’t put out the correct flow). Also during this time I was bored, so I opened up the pulse oximeter and looked inside (we kept getting an error 2 message and something was rattling around inside). I found the inside contents quite intriguing (the source of the rattling was the speaker inside that had broken free of the hot glue (factory hot glue mind you) that previously held the speaker in a recessed ridge. After whipping up some epoxy that shiznit was sitting in place drying. 

All the circuitry! (inside the pulse oximeter)

We then decided to go meet with SILAIS, which we did with the help of Popo (who is a terrific person to help us out with meeting folks). We met this one dude in SILAIS that took us into this control/meeting room for to meet the head of SILAIS for San Carlos. He also got us some work at the head of health services or something in the area (quite close to hostel for tomorrow morning). After that Dan and I went back and worked more on the nebulizers and also finished up inventory of the x-ray areas and looked at the O2 tanks (which we’re thinking of adding some chains around (and pouring some concrete to make a level surface) for our secondary project). 

Those tanks (on the slope with the caps we just put on today) (thinking on concreting a platform then putting in posts to secure a chain)

After that we packed up the tools and got one neb back to the nurse from the pediatric ward. I had also been working on cleaning a filter by poking it with the syringe needle and pushing the water through. After that pretty much just packed up tools and left for the day (we’ll be heading to the centro de salud tomorrow at 8 AM). After clocking out at 4:40 PM I headed to the bakery (bought two of those good breads from yesterday and this after chilling at home a bit and then recharged my phone. Pretty boring from there on (dinner was avocados B&R and tortillas and this brown slightly grainy thing to drink). Might go out a bit tonight, but probably not. Need to get some more sleep. Peace!

Those good pastries!
