    I was also looking for a thread on expired test strips. I only make an assumption you have covered this but didn’t see a thread. Is my search flawed or have you really not explored expired test strips? (I assume I just did a bad search.) Or is it possible this one was too obvious to even have its own thread?

  2. Chris

    My guess is that they works just fine. But it is just an opinion. We haven’t had any expire, so unless someone has some expired ones laying around…

    Expired Dexcom sensors work fine!

    I have never used an expired strip…

    Do you know why? I test about 20 times a day. How would a strip ever survive in my house long enough to expire!

Lab Values: Abgs, Electrolytes, Acid Base Balance, Metabolic Panel, Cbc, Coagulation

PaCO2: 35-45 mmHg (Respiratory component) PaO2: 80-100 mmHg (Respiratory component) Serum bicarbonate HCO3-: 22-26 mEq/L (Metabolic Component) Acidosis: < 7.35: H+ diffuses into cells and drives out K+, elevating K+ concentration in ECF Alkalosis: >7.45: H+ diffuses out of cells and K+ diffuses in Respiratory Regulation of Acid Base Balance: - Eliminating or retaining CO2 by the lungs also regulates acid-base balance. - The response is rapid, occur within minutes by altering the rate and depth of respiration - CO2 is a powerful stimulator of the respiratory system - Increasing ventilation increases pH by eliminating CO2 - Decreasing ventilation decreases pH by retaining CO2. - An acute rise in PCO2 is a powerful stimulant to respiration Renal (Metabolic) Regulation of Acid Base Balance: - The ultimate long-term regulator of acid-base balance - Slower to respond, but response is more permanent and selective - Maintain acid-base balance by excreting or conserving bicarbonate and hydrogen ions - When pH decreases, H+ ions are excreted, and HCO3- ions are formed and retained. - When pH increases, H+ are retained, and HCO3- are excreted - Excess loss of bicarbonate via kidneys/GI Continue reading >>

    Keto Breath?

    How bad does it smell? Can you avoid it with gum or mints?

  2. Tuxd

    you breath should not smell. Thats a symptom of ketoacidosis which is totally different. your urine will smell because thats were your liver will dump excess but ketones won't be flooding your body high enough to cause your breath to change.
    Are you detecting a change in your breath?

  3. Jason762

    Ermm... You DO get keto breath. I don't know if others can smell it, but I know I can certainly taste it.
    Just like how RANK ass bad breath can be tasted, so can keto breath.
    I notice keto breath especially after hard cardio exercise and in the mornings after sleeping.
    Yes, gums and mints can be used, but make sure it is sugar free as it can kick you out of keto. Also, some people have reported being kicked out of keto with artificial sweeteners, but I myself have had no problems with it.
    Honestly don't worry about it. Girls will be too busy noticing your new hot bod to give a s**t about your breath.

Metabolic Acidosis - Endocrine And Metabolic Disorders - Merck Manuals Professional Edition

(Video) Overview of Acid-Base Maps and Compensatory Mechanisms By James L. Lewis, III, MD, Attending Physician, Brookwood Baptist Health and Saint Vincent’s Ascension Health, Birmingham Metabolic acidosis is primary reduction in bicarbonate (HCO3−), typically with compensatory reduction in carbon dioxide partial pressure (Pco2); pH may be markedly low or slightly subnormal. Metabolic acidoses are categorized as high or normal anion gap based on the presence or absence of unmeasured anions in serum. Causes include accumulation of ketones and lactic acid, renal failure, and drug or toxin ingestion (high anion gap) and GI or renal HCO3− loss (normal anion gap). Symptoms and signs in severe cases include nausea and vomiting, lethargy, and hyperpnea. Diagnosis is clinical and with ABG and serum electrolyte measurement. The cause is treated; IV sodium bicarbonate may be indicated when pH is very low. Metabolic acidosis is acid accumulation due to Increased acid production or acid ingestion Acidemia (arterial pH < 7.35) results when acid load overwhelms respiratory compensation. Causes are classified by their effect on the anion gap (see The Anion Gap and see Table: Causes of Metab Continue reading >>

    I've wanted a ketonix for a while but am not going to fork over hundreds of dollars. So I followed some advice and got myself a cheap breathalyzer on ebay. Apparently they don't distinguish between alcohol and acetone.
    IT WORKS!
    Now I can measure easily whether or not I am in ketosis anytime I suspect I may have dropped out. The ketostix stopped working for me a long time ago as my body is very well adapted and I don't excrete a lot of measurable ketones.The breathalyzer is not much good for finding your millimoler value of ketones, but then again, by all accounts neither is a ketonix itself. The breathalyzer cost me $12 and you can get them cheaper. In fact, it's only the cheaper ones that work. You can get these breathalyzers as cheap as a few dollars.
    Here's the one I used below

    That reading above is while fully sober... * I swear * Only trouble is it beeps like crazy when it detects 0.05% or over (the legal alcohol driving limit in australia). I'm sure other models wouldn't beep.

    Thanks @yogipete ! This is both interesting and worrisome at the same time!

    I may get a cheap one myself, but in the meantime I'd love to see if others can replicate your results.

  3. yogipete

    My pleasure.

    I might also add that the reading is consistent regardless of my method of blowing etc... which is a problem that haunts the ketonix. I've done a few baseline tests on my partnerr who always blows 0 (she's currently non-keto) while I generally blow between .04 and .05 (but in any one moment of the day the reading is always identical regardless of my personal clumsiness in using the meter). I'm looking forward to testing some more non-keto friends.

While definitions vary, mild DKA can be categorized by a pH level of 7.25-7.3 and a serum bicarbonate level between 15-18 mEq/L; moderate DKA can be categorized by a pH between 7.0-7.24 and a serum bicarbonate level of 10 to less than 15 mEq/L; and ...

    We measure serum total CO2 content in lieu of measuring serum bicarbonate. The total CO2 content includes the serum bicarbonate as well as available forms of carbon dioxide (i.e., dissolved CO2 and carbonic acid). Generally, the serum bicarbonate comprises about 95% of the total CO2 content; thus we can use this measurement as an excellent estimator of serum bicarbonate. The total CO2 content normally equals 23 to 30 mEq/L of serum. Most laborat ...
