Mods to the Drip Rate calculator

“JS” had a nice idea – how about the gtts/min for folks who don’t have a ml/hr pump?  It’s now there, and I took the opportunity to make the navigation less clunky.  Well, at least /I/ think it’s less clunky.  Version 1.1 and should update automatically for folks who already have it installed.

PLEASE let me know if you find any problems!  Thanks.

 

Another day, another app…

The latest is the DTsEMT RSI Calculator – enter a patient category (adult or peds), enter the weight, and see the drugs.  Allows you to deselect drugs you don’t carry to get them out of the way, and lets you enter patient health concerns (ICP, hypotension, pregnancy, etc) after which it will color-code the drugs.  Choose the green ones for best result ;-)

Absolutely free, no guarantees, blah blah blah.  Android only, je me regret, and tested on a bigger screen – HTC Evo.  Let me know of any problems, please.  Thanks!

 

Quick update…

A second EMS tool, Drip Rate Calculator, is now freely available from the Android Market. This is version 1.0, so once again, anyone using it, please feel free to suggest improvements.  I’ll get to ‘em as time permits.

Just to say, I wrote this because I wanted a calculator that was a) free, and b) quicker to load than those embedded deep in Epocrates or programs of that sort.  No fuss, no muss.

Thanks!

Re-Written Android App

App Inventor was a lot of fun, but is being discontinued 12/2011.

I’ve since re-written the Drip Timer app so it’ll still be available. The good news is that the app went from 3.89 MB (App Inventor) to 320KB (native). If you’ve already installed it from here, please Menu -> Settings -> Applications -> Manage Apps and de-install it. Reinstall from the Market, or:

https://market.android.com/details?id=com.DTsEMT.DripTimer&feature=search_result#?t=W251bGwsMSwyLDEsImNvbS5EVHNFTVQuRHJpcFRpbWVyIl0.

Free*3 (no purchase, no ads, no fee)

Thanks!

Calls and Classes and Android Oh My.

I’ve written a couple of Android applications, which various folk have expressed interest in using, so here they are.  Absolutely free, tell your friends, etc. blah yadda.  Each comes with absolutely no warranty, use at your own risk, warning: choking hazard, and all that good stuff.  If you find an error, comment here to let me know and I’ll address it ASAP (which may not be all that S, be patient.)  These were written for and tested on my HTC Evo 4G.  Your screen may look slightly different if the aspect ratios are very much different.

The first Android app I wrote was Oxygen.  This allows you to enter PSI on the tank and the flow rate in LPM.  Press “Done” on your keyboard to move it out of the way, then tap the tank size you’re using.  The time remaining for the tank is calculated.  PSI is automatically reduced by 200 prior to calculation because most consider 200 PSI the “safe residual pressure” – at which point you should be looking for that new tank.  If you tap “Countdown” a counter will appear and you can put your phone away.  It’ll start buzzing when the tank nears empty.

The other “Hey-that’s-kind-of-neat-let-me-have-it” program is DripTimer.  Instead of watching the IV drip chamber and your watch, and losing count and all of that fun stuff, just run DripTimer.  Tap the upper portion of the screen each time a drop falls into the chamber.  I made the tap area quite large so you can hit it without having to look at it.  Tap  “10” if you’re using a 10-drop set, or “60” for a microdrip set.  Sorry, 15-drip-guys, I didn’t have room.  The ML/Min and ML/Hr is displayed.  Two or three drip-taps work, obviously the more actual drops you count the more accurate the calculation will be.  If you’d like to use it to count Breaths or Heartbeats (useful for tapping out neonate heart rates), tap “Breath” instead of “10” or “60”.  The display changes from “Gtts/min” to “Breaths/min” and you should ignore the ml/hour numbers, of course.  Maybe next version I’ll just blank those…

Unfortunately, WordPress does not allow the hosting of files and mine own host, alas, no longer provides this service.  The files are small enough that I feel no guilt or shame.  I was however forced to rename the files as DOC files so WordPress would allow the upload.

Windows users:  Right click either Driptimer or Oxygen and select “Save link as”.  For the file name, change the extension from “.DOC” to “.APK” (capitalization is unimportant.)

Next, you may either email the file to your Android device as an attachment, or connect the phone via USB and copy it to your SD card.

Finally, you’ll need a free file explorer program (like Astro, available in the Market) to open the file.  Android knows what to do with APK files and will install the program for you.   Since my program isn’t coming from the Market, though, you’ll need to first press [Menu button] Settings -> Applications -> Unknown Sources and make sure there’s a check mark in the box.

Have fun, leave comments if you find bugs, etc.  Again, I have other things on my plate at the moment and can’t promise features/bugfixes right away but I would appreciate any feedback.

Statistical Stuff for 2010

Huzzah!  It’s time again for the DTs Correlation Does Not Equal Causation Festival!

In 2010, DTs ran a total call volume:  775 calls, of which 379 were deemed BLS, 360 were ALS, and 17 were CCT (the CCT numbers should increase in 2011, for DTs is now running such calls since mid-December 2010.)  A mere 31 calls were “lights & sirens” at the request of the sending facility.  We were placed in service prior to patient contact on 35 occasions.  Average number of calls per day, around 7, with a maximum during a single calendar day of 12.  Note that a shift spans two calendar days (eg 06am 12/1 to 06am 12/2) so the actual numbers are probably higher, but I’m too lazy to figure that one out this time.

DTs and his Merry Crew ran 369 male, and 406 female patients.  This is typical; guys don’t tend to go to hospital as often, and the ladies are still living longer.

The average age of all patients was 54 years, with a minimum age of 1 hour (actually probably less than an hour, but my tracking software goes all the way down to “1”) and our oldest patient was 102 years.

Total patient weight – welcome to America – was 42,281kg (or 93,018lbs, or 46.51 tons o’ patient.)  Total weight of all males was 28,165kg making the average male weight 76.32 kg, while the average female patient weighed 66.9kg.

Of our patients who spoke NO English whatsoever, 27 spoke only Spanish; 4 spoke Arabic, 4 Farsi, 3 Korean, 3 French, 2 Urdu/Hindi, and 2 Vietnamese, and one… Greek.  Did not see that coming.

In the transport gig patient pickup is usually from a facility, rather than from residence or roadside. 240 patients were picked up at a single standalone ED, with 176, 106, and 104 patients taken from the big three area hospitals.

As to where they’re taken, 116 went to a general hospital, 110 to a level 1 trauma center, and 73 to a specialty rehab facility. The rest are sprinkled into nursing homes, specialty hospitals (eg Childrens Hospital, or the MedStar Burn Unit), and 45 to residences.

Apropos Veterans Day

In the past month – a normal month for DTs, by the way – I have met:

a Cold War submarine commander;

an original  Tuskegee airman;

a soldier/POW from the Battle of the Bulge;

a tanker from Patton’s Third Army;

at least three infantrymen who saw France – beginning D-Day;  a couple more who toured Europe via the scenic Italian route;

an Air Force officer who served in Vietnam;

a young man on leave who is still serving our country…

Folks are right, there are heroes to be found when one is in the Fire/EMS gig, and it’s our privilege to serve them.
