|
How do you calculate bicarb deficit?
|
Bicarbonate deficit = 0.3 x body weight (kg) x (HCO3 normal - HCO3 measured).
|
|
|
What is winter's formula?
(Expected resp. correction for met. acidosis) |
PCO2 = 1.5 * (HCO3-) + 8
|
|
|
Explain how body deals with Co2 produced from fat and carb metabolism.
|
The foods are broken down into Co2. The co2 is quickly converted to hco3 + h+ by rbcs. AT THE LUNG, bicarb converted back to CO2, breathed out. This is for fat/carb - proteins straight-up produce h+ in the blood.
|
|
|
Expected metabolic correction for resp. acidosis/alkalosis
|
Acute : 1 hco3 for every 10 co2
Chronic : 4 hco2 for every 10 co2 |
|
