Xj220c argues that §301(b) of the Food, Drug, and Cosmetics Act (FDCA), 21 USC §331(b), makes it is illegal in the United States for a consumer to change his xPAP pressure. For anyone who is interested, the FDCA can be found several places on the internet, including the FDA website,
http://www.fda.gov/RegulatoryInformatio ... ActFDCAct/. To provide a little more context, I will quote a couple of additional subsections (there are more after that):
The following acts and the causing thereof are hereby prohibited:
(a) The introduction or delivery for introduction into interstate commerce of any food, drug, device, or cosmetic that is adulterated or misbranded.
(b) The adulteration or misbranding of any food, drug, device, or cosmetic in interstate commerce.
(c) The receipt in interstate commerce of any food, drug, device, or cosmetic that is adulterated or misbranded, and the delivery or proffered delivery thereof for pay or otherwise.
(d) The introduction or delivery for introduction into interstate commerce of any article in violation of section 404, 505 or 564.
Xj220c correctly notes that a consumer changing a pressure setting would have to be both an "adulteration" and "in interstate commerce" to violate the law.
Take interstate commerce first. The act as a whole is clearly aimed at manufacturers and sellers, not consumers. Look at those subsections above. They revolve around references to delivery, payment, and commerce. The rest of the act is the same way. Historically, the FDCA was a consumer protection measure growing out concerns about contaminated food and drugs, not misuse by individuals.
Imagine that the act applied to the consumer. Remember, it applies to food as well as drugs and medical devices. If someone were to smoke a cigar after dinner and allow the ash to fall into what was left of his ice cream, he would have adulterated food. Why, if I were to make a chicken salad sandwich (sorry Rooster), you might say I had adulterated my chicken with mayonnaise and pickle. It wouldn't be in interstate commerce though, and no sensible person would argue otherwise.
Xj220c doesn't fight this issue very hard for an owned machine, but proposes that a rented machine is in interstate commerce. I don't think so. Any reuse of the machine would come after a reset, refurbishing, new prescription, and new setting. Whatever you might say about the blower itself, the so-called adulteration would never make it into interstate commerce.
The real weakness of xj220c's argument, though, is his contention that a change in a pressure setting is an adulteration. He seems to be saying that any change in state is an adulteration, but that is not so.
First, standard definitions of adulteration equate it with contamination, not mere alteration. The web version of Merriam-Webster defines adulterate as
to corrupt, debase, or make impure by the addition of a foreign or inferior substance or element; especially: to prepare for sale by replacing more valuable with less valuable or inert ingredients.
Tweeking a dial – or the software equivalent – just doesn't meet that definition. It's not like ruining good chicken with mayonnaise.
Second, the FDCA doesn't rely on a dictionary definition. Section 501, 21 USC §351, states when a drug or device shall be deemed to be adulterated. It is too long to quote here, but anyone can read the section at the FDA web site cited above. It starts out terms that echo the theme of contamination:
(a) (1) If it consists in whole or in part of any filthy, putrid, or decomposed substance; or (2)(A) if it has been prepared, packed, or held under insanitary conditions whereby it may have been contaminated with filth, or whereby it may have been rendered injurious to health ...
Much of the section has to do with concepts that only apply to drugs, like purity. But to the extent it refers to devices, it defines adulteration in terms of failure to conform to performance standards and regulations established pursuant to other sections of the act. See subsections (e) and (h), for example. There is nothing remotely suggesting that changing a setting could be deemed an adulteration. I certainly don't buy xj220c's analogy between changing a setting and installing new firmware. New firmware would require the manufacture to file a new §510(k) report, completely different from changing a setting that is designed to be changed.
Third, xj220c's argument is a classic example of an argument that proves too much. If it would be a violation of §301 for me to change my pressure, why wouldn't it be just as much a violation for my doctor or respiratory technician to change it? The section doesn't say "except doctors or RTs." But that makes no sense, you protest. True, but most of us don't think it makes sense to tell consumers that they cannot change their pressure either. If you take one section of a large piece of legislation out of context and try to apply it to a situation it isn't intended for, you get wacky results. This act is about forcing manufacturers and sellers to meet standards of safety. Section 301(b) isn't meant for doctors or patients, but if you interpret it the way xj220c proposes, it applies equally to both, and no one can change the pressure. Likewise, if tweeking the pressure is adulteration, why not tweeking the ramp time, or the minimum start-up pressure, or a dozen other parameters? It is far more logical to conclude that changing a pressure setting is not adulteration within the meaning of the FDCA.
Xj220c had two more arguments, but they did not refer to any specific law so I'm going to give them short shrift, especially since I've been long-winded already. Insurance fraud? He relies on a recollection that medications and devices are only covered if used "as prescribed" by a physician. I don't remember any such "as" in my benefit booklet, but it's at the office. I am supposed to take Lipitor every day. I would hate to think that on those mornings when I neglect to do so, and there have been more than a few, I commit insurance fraud. I trust that if I ever have a heart attack, Blue Cross won't say, "Sorry PST, no stent for you. And by the way, you owe us for the last five years of Lipitor." That is what xj220c is saying, and I've never heard of such a thing. Using a device without a prescription? He just speculates on what the law might be in some state. Find a law and we can see how it has been interpreted. I will just propose one more hypothetical. Many people with low incomes and no insurance try to stretch their medications by taking less than prescribed. If I break that Lipitor pill in half every morning to eek two months out of each bottle, am I breaking a law? If so, name it; any state will do.
In summary, I remain unconvinced that anyone has yet found the legendary law that makes it illegal for a patient to change the pressure setting on his xPAP machine. It is something that I don't do, by the way. I agree with LinkC and several others on this one. I talk to my doctor first. But maybe I just lucked out with a good doctor and an easy adjustment, so I don't want to pass judgment on others. If I did decide to change my pressure, though, I would not worry for one second that I was breaking the law.
