Metabolic Acidosis Compensation Formula

Acid Base Disorders

Arterial blood gas analysis is used to determine the adequacy of oxygenation and ventilation, assess respiratory function and determine the acid–base balance. These data provide information regarding potential primary and compensatory processes that affect the body’s acid–base buffering system. Interpret the ABGs in a stepwise manner: Determine the adequacy of oxygenation (PaO2) Normal range: 80–100 mmHg (10.6–13.3 kPa) Determine pH status Normal pH range: 7.35–7.45 (H+ 35–45 nmol/L) pH <7.35: Acidosis is an abnormal process that increases the serum hydrogen ion concentration, lowers the pH and results in acidaemia. pH >7.45: Alkalosis is an abnormal process that decreases the hydrogen ion concentration and results in alkalaemia. Determine the respiratory component (PaCO2) Primary respiratory acidosis (hypoventilation) if pH <7.35 and HCO3– normal. Normal range: PaCO2 35–45 mmHg (4.7–6.0 kPa) PaCO2 >45 mmHg (> 6.0 kPa): Respiratory compensation for metabolic alkalosis if pH >7.45 and HCO3– (increased). PaCO2 <35 mmHg (4.7 kPa): Primary respiratory alkalosis (hyperventilation) if pH >7.45 and HCO3– normal. Respiratory compensation for metabolic acidosis if pH Continue reading >>

    Does anyone have issues with kidney function and still successfully follow the LCHF regime? Although I am not being treated as such!, i.e. dialysis, I've been told my kidneys do not work at full capacity and have deteriorated significantly over the last couple of years. I am a little worried about what I have read about ketosis affecting the kidneys. Is it just a case of drinking lots of water? Should I take the issue up with my gp or renal consultant?

    I've followed a ketogenic diet for around 2 years or so and I too have CKD and take Ramipril daily,My eGFR level has improved slightly on this diet,all I would add is don't go mad with eating protein and concentrate more on getting your calorific needs from fats and veggies etc.

    Thank you for this advice. I have only been on the LCHF diet for 2 days so far. Already my blood sugars have stabilised so that's a good start. So far my diet has consisted of eggs, bacon, burgers, broth, cheese, double cream, nuts and berries. I dont feel at all hungry most of the time. Of course its too early to tell if there is any weight loss.
    So far I have not had any negative feedback re this diet although I saw my dietician yesterday and she wouldn't endorse it
