Good morning to all! Low of 25, going up to 38 today, snow likely tonight. Winter storm warning goes into effect tonight until Saturday morning. Already snowing in the west and the Four Corners area. They are supposed to get 20+ inches. The weather guessers are not 'predicting' the amounts for our area....ussually not a good sign.
As an active paramedic, it is proven that AED's and early CPR intervention have increased the 'out of hospital' survival rate of cardiac arrest. One has to remember these studies lump ALL uses of AED's into the statistics, doesn't matter if it was used in the city or rural. Naturally, the closer proximity to an appropriate facility, the greater the survival rate. There are SO MANY VARIABLES, not one case is similar to another.
Another aspect of 'survival' is the time, as Don mentioned. Our service has 35-40 ALS (advanced life support) units on the street 18 hours a day, about 15-20 units between 01:00 to 05:00. A really good chance that a unit will be on scene within 4-5 minutes or less. These units have the capability to do EVERYTHING the ER would do in a cardiac arrest situation. We actually stay on scene and treat for up to 45 minutes. Also, the city fire dept responds, staffed with at least 2 paramedics and full equipment. They ussually get on scene about a minute sooner. If transport does take place, the unit may drive past 2 hospitals to go to an appropriate cardiac treatment facility.
As Don mentioned, the KEY is EARLY RECOGNITION OF THE SIGNS!. Better to get checked out than ignore the signs. The typical signs may not be present at all, sometimes are different, sometimes are only slight.
In my case, I experienced 'a pain' in my shoulder blade. It occured right after I loaded a patient into the ambulance. I thought I pulled a muscle. The pain was intermittent and not really severe. I got off duty an hour later and went home. I woke up about every hour for the next 4 hours with the same pain...not worse, no different areas. On the last time I was awakened, NOW I KNEW! Sweating, nausea, same pain but not going away. I called 911, took aspirin, and waited for what now seemed an eternity. Our local EMS is paid, staffed 24/7, and are 7 miles away. Took them 10 minutes to get here. Transport to the appropriate hospital takes 40 minutes (we are rural, up in the mountains). About 12 minutes away from the hospital, I went into cardiac arrest. There was only 1 medic in the back with me. He started CPR, and was able to 'shock' me once (defibrillated). I came back just as we arrived at the ER. I went into arrest again at the hospital during a catheterization procedure.
I'm here, no cardiac damage. The cardiologist has no idea what caused the clot to form in my heart. I had a complete physical including bloodwork just 2 weeks earlier. The bloodwork showed 'book perfect' levels of cholesterol, sugar levels, etc... The cardiologist stated that I had the coronary arteries of a 35 year old! To this day, no arrhythmias, no further incidents, no high B/P, no ???
To sum this all up....pay attention to what your body is telling you! You never know!
