4.2 Respiratory Acidosis - Causes

Acid-Base Physiology The arterial pCO2 is normally maintained at a level of about 40 mmHg by a balance between production of CO2 by the body and its removal by alveolar ventilation. If the inspired gas contains no CO2 then this relationship can be expressed by: paCO2 is proportional to VCO2 / VA where: VCO2 is CO2 production by the body VA is Alveolar ventilation An increase in arterial pCO2 can occur by one of three possible mechanisms: Presence of excess CO2 in the inspired gas Decreased alveolar ventilation Increased production of CO2 by the body CO2 gas can be added to the inspired gas or it may be present because of rebreathing : Anaesthetists are familiar with both these mechanisms. In these situations, hypercapnia can be induced even in the presence of normal alveolar ventilation and normal carbon dioxide production by the body. An adult at rest produces about 200mls of CO2 per minute: this is excreted via the lungs and the arterial pCO2 remains constant. An increased production of CO2 would lead to a respiratory acidosis if ventilation remained constant. The system controlling arterial pCO2 is very efficient (ie rapid and effective) and any increase in pCO2 very promptly re Continue reading >>

    Whenever I do keto, I end up lasting for about 1-2 weeks cuz the god damn carb up days kill me.
    So I've decided this time, ONLY ONE CARBUP DAY on the last WORKOUT DAY of the week, if I workout 4x a week then it's a sunday, if 3x its a saturday.
    Now I realize that I still have to eat below maintenance to lose weight. I've lost a LOT of water weight this week. Monday I was 194-196, today this morning I was 177, drank some water and ate breakfast was 183, after gym 186 lol.
    Okay I have a basic understanding of carb up days, HIGH CARBS/HIGH PROTEIN, LOW LOW FAT. I'm guessing Carbs + Fats = all the weight will be regained.
    I'm deciding to eat carbs only half day (morning), they will consist of TWO of these meals (Spaghetti/Mozarella/Chicken Breasts OR THIGHS, Grilled Chicken Sandwhich in a bun, or Grilled Chicken with rice AND OR a buttered baked potato).
    After around 2-3, I will workout, High Reps/High Sets/Little Rests and deplete my glycogen stores and then top it off with 45 minutes LISS.

    How long have you been on the diet for?
    What are you specs? (Weight, BF%)
    You want to have your refeed as your last meal of the day.
    You do not need to eat below maintenence.
    The main reason to keep fats lower is just to have more room for carbs to be absorbed.
    You want to gain weight on this day as it shows that you have replenished your muscles with glycogen.
    Weigh yourself in the morning of your refeed day. This is your "BASELINE WEIGHT"
    Then again before bed or the next morning. This is to ensure you gained and had a proper refeed
    The goal is to get back to "baseline weight" within 2-3 days and then lose 1-3 pounds by your next refeed.
    Eat what you are craving and keep carbs very high.

    Eat what you are craving and keep carbs very high. I've been on the KETO diet since monday.
    Age 18, Height 5 feet 9 inches, Weight current 183-186, BF is around 20-30 percent...I've never done a Bodyfat test so this is just a BALLPARK guess. I have a gut and slight moobage but no stomach rolls or triple chins or so much fat that to wash my man parts I have to lift my stomach.

Intracellular buffers include hemoglobin in erythrocytes and phosphate ...

  • Metabolic Acidosis Compensation Mechanism

    Definition In a compensated respiratory acidosis, although the PCO2 is high, the pH is within normal range. The kidneys compensate for a respiratory acidosis by tubular cells reabsorbing more HCO3 from the tubular fluid, collecting duct cells secreting more H+ and generating more HCO3, and ammoniagenesis leading to increased formation of the NH3 buffer. Compensated respiratory acidosis is typically the result of a chronic condition, the slow natu ...

    Acid-Base Physiology 5.5.1 Hyperventilation Compensation for a metabolic acidosis is hyperventilation to decrease the arterial pCO2. This hyperventilation was first described by Kussmaul in patients with diabetic ketoacidosis in 1874. The metabolic acidosis is detected by both the peripheral and central chemoreceptors and the respiratory center is stimulated. The initial stimulation of the central chemoreceptors is due to small increases in brain ...

  • What Is Respiratory Acidosis

    Respiratory Acidosis is a pathophysiological category of acidosis and refers to those acidoses caused by primary disturbances in ventilation. Although ventilatory defects can cause significant decreases in the blood pH, renal compensatory mechanisms can largely correct the pH over several days. The fundamental cause of all respiratory acidoses is insufficient alveolar ventilation, resulting in an increase in the partial pressure of arterial carbo ...
