What is a list of the normal arterial blood gas values?

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


What is the formula for AA gradient?

PAO2 - PaO2 ****************************************** PAO2 is the Alveolar Air Equation: PAO2 = FiO2 (Pb- Ph20) - PACO2/R Notes: Pb = 760 mmHg Ph20 = 47 mmHg R = 0.8


A paco2 of 65 and a pao2 of 88 what do these results mean?

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.


How do you calculate PAO2?

{(Pb-47)FIO2} - (PaCO2 X 1.25) "only use the 1.25 if FIO2 is >60%"


How do do the Alveolar air equation?

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


A patient is breathing 21 of oxygen at 1 atmospheres If his PaCo2 is 40 mmHg and his RQ is 1 and his A-a gradient is 30 what most closely approximates this patients Pa02?

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.


What is Normal arterial partial pressure torr?

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.


What is the normal arterial PaO2 in healthy neonates?

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.


What are the normal arterial blood gas values?

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!


What is the normal range of PAO2 - PaO2 for healthy young adults breathing room air?

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.


What is a normal PaCO2?

The PaCO2 range is 35 to 45 mmHg


What is elevated PaCO2?

It's a level of carbon dioxide in the blood that's higher than normal.
