It prompts me to give an account of a problem we identified with carbon monoxide some time ago. Carbon monoxide binds to iron in the blood pigment haemoglobin, preventing the uptake of oxygen and is therefore relevant to your observations. I apologise for the long post, but it is relevant to PD. In Dec 1995, we had friends come for a meal and followed the meal by a trip out to the theatre. On our return we were surprised and worried to find that a Carbon Monoxide detector in our LOUNGE was sounding a warning that Carbon Monoxide (CM for short from now on) had been detected. We suspected our gas central heating boiler which was the only source of CM alight and switched it off, and thoroughly ventilated the house. We suspected the CM detector was faulty because it was difficult to see how a gas boiler in a different part of the house would produce CM in the LOUNGE. The following day we had the Gas Co. visit and check our appliance, the boiler and our Gas cooker. Both were deemed to be burning and functioning correctly although the gas fitter did not have a CM detector, because, "These were highly specialised, expensive and needed regular calibration". We contacted the distributers of the CM detector (First Alert) who suggested I send them the sensor for analysis. I did this and within 48hrs they phoned me to state CM traces HAD been found on the sensor. I then hired a highly accurate (expensive) calibrated CM meter from a specialist company and proceeded to take measurements. You may already know this, but CM is measured in parts per million (ppm) and the danger from exposure to it is a function of both LEVEL of CM and DURATION of exposure. In other words even quite high levels can be tolerated for very short periods but lower levels can still be dangerous if exposure to them is over long periods of time. Remember that CM is invisible and odourless and therefore can only be detected and measured by instruments. Background levels in a home are around 1ppm to 5ppm. I first checked the house without appliances alight, READING: 1ppm. Checked the boiler and around it, no increase on 1ppm. Lit the gas oven, level in kitchen increased only slightly to 2ppm. Lit the gas rings, still only around 2ppm. Tried the gas grill, WHAM.... Up went the levels which peaked at 95ppm within a few minutes. Using the extractor fan reduced the figure by about half but it was still at an unacceptably high level of about 45-50ppm. I then experimented and found that placing a kettle filled with cold water on the gas to boil, produced similar high levels. This made scientific sense as CM is released when there is incomplete combustion of carbon fuel and, because the gas flame reduces in temperature when passing through a cold surface, it does not burn so well. After I was diagnosed, the PD accelerated and until my wife retired I spent some time alone at home. In this period during which I became gradually worse, I used to make a drink and breakfast in the kitchen and sit in there longer than had previously been my habit. 95ppm is not sufficient to make a person ill over a short period of time but what about over a longer period of time? The most startling thing of the lot was this. After spending a little time in the kitchen taking these readings and shouting them out to my wife in the next room to note them, I ventilated and left the kitchen to go and write down my findings properly. I COULD NOT! I COULD NOT WRITE. I COULD NOT SIGN MY NAME ONCE and in trying to write numbers 1 till 10, COULD NOT GET PAST 2. This was early in my illness, when I was still on Eldepryl, and I had never till that moment had a freezing episode on writing. I gradually recovered until back to normal about one hour later. Repeated the experiment. SAME RESULTS! We changed the Gas cooker, we now use an electric kettle instead of the gas one, we use an electric toaster not the Gas grill for toast, and always have the extractor fan on BEFORE we start cooking. Tips for reducing CM with gas cookers besides servicing them: 1. When boiling water in a kettle or pan, reduce the flames so that the TIPS of the flames play the pan bottom not the middle cone of the flames. 2.. When using grills, do not turn the flames higher than necessary. The flames on a grill generally curve upwards towards the cold metal. This reduces the temperature of the flames and produces CM. 3. The colder the surface that the flame plays on, the more CM is produced. As the pan and contents heat up, the CM given off reduces. Thus the most CM given off is IN THE FIRST FEW MINUTES. Therefore, reach for the "extractor fan switch" or window, BEFORE you start cooking. 4. Play safe if you can, use elecric toasters and kettles if possible. Check all combustibles and ventilation. Incidentally, I got back to First Alert about grills etc and the executive in charge of the trouble shooting team said he found gas grills a common high source of CM in homes. I accounted for the triggering of the detector alarm by the fact that my wife had cooked the dinner meal for the 4 of us and we had closed up and gone out not too long afterwards, thus not allowing the usual time for the CM to clear. The First Alert detector works on CM level and DURATION of exposure. These are my thoughts as I think them: Was CM a contributory cause over the years? If not, is it just that us PDers are more susceptible to CM because of the reduction in available oxygen? Is it a combination? I do not know. It is food for thought though, because many of you have mentioned carbon monoxide and oxygen uptake as having an affect on PD symptoms. Ernie Peters <[log in to unmask]>
