There are many measures of Arterial Blood Gases. The most common measure oxygen (by PaO2) and carbon dioxide (by PaCO2) levels. Normal PaO2 is 80-100 mmHg. Normal PaCO2 is 35-45 mmHg. Bicarbonate is sometimes measured and its value is 22-26 mmHg. Other measurements are also taken depending on the situation. Source: http://en.wikipedia.org/wiki/Arterial_blood_gas
PAO2 - PaO2 ****************************************** PAO2 is the Alveolar Air Equation: PAO2 = FiO2 (Pb- Ph20) - PACO2/R Notes: Pb = 760 mmHg Ph20 = 47 mmHg R = 0.8
high level of carbon dioxide in the blood stream which could be from a multitude of reasons. At 65 mm hg, the CO2 level is very high relative to normal range of 35 o 45. The PAO2 is in normal range at 88. The high PACO2 would cause the pH of the blood to be elevated without increased bicarbonates from the kidney or external delivery to compensate.
{(Pb-47)FIO2} - (PaCO2 X 1.25) "only use the 1.25 if FIO2 is >60%"
The alveolar air equation is: PAO2 = FiO2(Pb-47)-(PaCO2/R) where: PAO2 is the partial pressure of oxygen in alveoar gas; FiO2 is the fraction of inspired oxygen (on room air this would be 21%); Pb is the barometric pressure (at sea level this is 760 torr); 47 is the partial pressure of water vapor; PaCO2 is the partial pressure of carbon dioxide in blood; R is the V/Q mismatch, which is 0.8 unless stated otherwise So, if a person is breathing room air at sea level, their PaCO2 is in normal range (let's say 40mmHG, since normal is between 35-45mmHg), and their respiratory rate is 12: PAO2= .21(760-47)-(40/0.8); .21(713)-(50)= 149.73-50=99.73 So the PAO2= 99.73mmHg
The patient's PaO2 can be estimated by using the alveolar gas equation: PaO2 = (FiO2 × (Pb - PH2O)) - (PaCO2/RQ). Given the patient is breathing 21% oxygen at 1 atmosphere, FiO2 is 0.21, and PB is 760 mmHg. Using the formula: PaO2 = (0.21 × (760 - 47)) - (40/1) gives an approximate PaO2 of 150 mmHg.
The normal arterial partial pressure of oxygen (PaO2) is typically between 75-100 mmHg when measured at sea level in a healthy individual. Normal arterial partial pressure of carbon dioxide (PaCO2) is usually between 35-45 mmHg.
The normal arterial partial pressure of oxygen (PaO2) in healthy neonates typically ranges from 50 to 70 mmHg shortly after birth. This value can vary depending on the infant's age in hours, with PaO2 generally increasing as the newborn transitions to extrauterine life. Within the first few days of life, the PaO2 may rise to around 70-100 mmHg in healthy term infants. It's important to monitor these levels to ensure adequate oxygenation.
The normal values for Areterial blood gas (for adults!) are as follows;Pao2 >> 12-15kPa (90-110mmHg)Paco2 >> 4.5-6.1kPa (34-46mmHg)Bicarbonate >> 21-27.5mmol/lH+ ions >> 36-44mmol/l (7.35-7.45 pH units)I also referred to the Baillière's Nurses Dictionary to check!
The normal range of the alveolar-arterial oxygen gradient (PAO2 - PaO2) for healthy young adults breathing room air is typically less than 10 mmHg. A higher gradient may indicate a gas exchange abnormality in the lungs.
The PaCO2 range is 35 to 45 mmHg
It's a level of carbon dioxide in the blood that's higher than normal.
