Truncus bronchomediastinalis töms i förgreningen v. jugularis och v. subclavia, PaCO2 hålls normalt i början, vid mjölksyra börjar PCO2 falla i slutet för att 

respiratory acidosis = pCO2 > 42; Acute respiratory acidosis: Change in pH = 0.008 X (40 - PaCO2) vs. chronic respiratory acidosis: Change in pH = 0.003 X (40 - PaCO2) determine if another primary acid/base disturbance is occurring calculate AG; if HCO3 < 24 + (pCO2-40)/10 x 3(+/-1) then there is a superimposed primary metabolic acidosis

Helium). As more carbon dioxide dissolves in water, its p CO 2 rises until it equals the p CO 2 of the overlying atmosphere. Arterialized ear lobe blood samples have been described as adequate to gauge gas exchange in acute and chronically ill patients. It is a safe procedure, usually performed by medical technicians. We have conducted a prospective study to verify the validity of this method. One hundred and fifteen consecutive adult patients were studied.

ETCO2 monitoring cost is $1080 via the ventilator per day. •This research focused on if there is a positive correlation between ETCO2 and PaCO2. If so, Definition of Paco2. The pCO 2 is the partial pressure of carbon dioxide (CO 2) in arterial blood.It is also represented as PaCO 2.This measurement indicates the effectiveness of alveolar ventilation, given the diffusing capacity of the gas.

1. pCO2/HCO3--pK=6.1, but pCO2 and HCO3 can be independently regulated by lungs and kidneys. 2. Hemoglobin--histidine residues. When in deoxy form, Hg can buffer more acid--CO2 is transported to the lungs as HCO3. 3. Cellular and plasma proteins, intracellular organic phosphates, bone (carbonates and phosphates).

Measurement of PCO2. analyzed with a radiometer to measure PaO2 and PaCO2.

The amount of pressure exerted by carbon dioxide dissolved in the blood is known as the partial pressure of carbon dioxide, or pCO2, according to Eastern Kentucky University. In healthy people, the normal level of pCO2 is 35mm to 45mm of mercury, says Orlando Regional Healthcare.

(akut). HCO3. -=24+((pCO2-5,3)/1,3).

Two factors each have a significant impact on the pCO2. 1. pCO2/HCO3--pK=6.1, but pCO2 and HCO3 can be independently regulated by lungs and kidneys. 2.

Difference between arterial PaCO2 and end-tidal PCO2 In a healthy person breathing room air, the difference between arterial PaCO2 and end-tidal PCO2 is small. => end-tidal PCO2 is about 2~5mmHg lower The size of this difference is a simple index of the amount of alveolar dead space.

Carbon dioxide reacts with water to form bicarbonate and carbonate ions, such that the relative solubility of carbon dioxide in water is greater than that of other unreactive gasses (e.g. Helium).
