Let's start with understanding the question. Partial pressure is defined as the fractional percentage of the gas in the overall gas mixture times the total pressure in Atmospheres. If we assume we're Scuba diving using air as our breathing gas, then the fractional percentage of nitrogen is 79% (or .79). Oxygen make up the majority of the balance at 21% (.21) Air is made up primarily of these two gasses. All other gasses that comprise air are considered "trace" gasses. Carbon dioxide is one of these trace gases, and accounts for about 0.039% percent of air by volume.
If we assume for a moment that we're at sea level, then the total pressure, by definition, is 1 Atmosphere (atm). This means that the partial pressure of nitrogen in air at sea level is .79. Oxygen is .21. Carbon dioxide is .00039.
Every 33 feet a diver descends in sea water adds one additional Atmosphere to the Total Pressure. This means that Total Pressure at 33 feet is 2atm and at 66 feet is 3atm. PPO2 (partial pressure of oxygen) at 33 feet is .42. PPN (nitrogen) is 1.58. PPCO2 (carbon dioxide) is .00078. At 66 feet of sea water PPCO2 is .00117 (.00039 X 3atm).

NO2 CO2 SO2 is in a bottle the partial pressure of NO2 is 1.25 atm and the partial pressure of CO2 is 2.63 atm if the total pressure of the gases is 11.20 atm what's the partial pressure of SO4?
The partial pressure of SO4 in a bottle of NO2, CO2, and SO2, is 7.32 atm.
Does a partial rebreather mask breath in CO2?
yes but only the ambient CO2 it is a NITROX mask for elevated O2 between 40 and 60 % the rest is AIR which contains Co2 at atmospheric pressure.. 1 BARAdditionAssuming you are talking about some kind of full face diving mask with a regulator attached, you will be rebreathing some gas you have exhaled. So yes, you will be rebreathing CO2 - which will be at a greater concentration as well as a greater partial pressure than the CO2 at atmospheric pressure. But it will be minor amounts. However if you are talking about a hospital type of application then it is a different answer.
What is the difference between pco2 and paco2?
pco2 is partial pressure of o2 in the capillary and paco2 is partial pressure of co2 in the arteries. So, one is a measurement of O2 and the other is CO2
How do the structures of alveoli and capillaries support the function of gas exchange?
Exchange of gases in alveoli takes place through diffusion. This diffusion takes place to partial pressure differences among the gases O2 and CO2. The partial pressure of O2in alveolar sac = 103 mm Hg The partial pressure of O2 in blood = 50mm Hg The partial pressure of CO2 in alveolar sac = 28 mm Hg The partial pressure of CO2 in blood = 45 mm Hg As a result, the O2 from alveolar sacs diffuses into blood. the CO2 diffuses from blood into lungs.
What is the partial pressure of oxygen in blood gas a mixture of N2 O2 and CO2 if the partial pr. of Nitrogen 630 mm of Hg and partial pressure of CO2 is 39 mm of Hg?
If the total (=atmospheric) gas pressure is 760 mm Hg, then the remaining partial pressure of 760 - (630 + 39) = 91 mm of Hg is for the 3rd gas in blood: Oxygen (O2)
What is the partial pressure of CO2 in the arterial and venous blood?
The normal partial pressure of oxygen in arterial blood is 75-100 millimeters of mercury. In comparison the partial pressure of oxygen at sea level is 750 millimeters of mercury.
How refreshing the air in the air sacs helps to maintain a steep diffusion gradient?
It increases the partial pressure of oxygen, so the concentration is higher than that of the blood. Therefore the partial pressure of CO2 decreases , so Co2's concentration is lower than the bloods.
What is PaCO2?
The concentration of Carbon Dioxide in arterial blood. Partial (Pa) Carbon Dioxide (CO2) pressure in ABG.
What is co2 blood level?
CO2 in the blood stream can be measured from bicarbonate in the blood or pCO2 (partial pressure). Normal CO2 measured from bicarbonate is 22-28 mEq/L Normal pCO2 is 35-45 mmHg
Which gas law explains why there is as much CO2 exchanged between the alveoli and blood as there is O2 exchanged despite the fact that the partial pressure difference is so much smaller for CO2?
Henry's law
What is the partial pressure of oxygen in a balloon?
The partial pressure of oxygen will vary according to where you look. Atmospheric oxygen partial pressure is approximately 21% of the atmospheric pressure of the location at which you measure (typically around 1 atmosphere at sea level, making the partial pressure of oxygen at seal level 0.21 ATM or 21.3KPa). The value varies geographically and with time, but also varies in different tissues of organisms, since not all oxygen available is absorbed, and complex multicellular organisms will have certain tissues (respiring muscle) that use up oxygen, resulting in a lower partial pressure there.normal oxygen partial185.4 kPa or in another unit:100 mmHg in the arterial blood. The partial pressure on the alveolar site is about 105 mmHg.
Does partial pressure of oxygen increase during exercise?
You can consume up to ten times as much oxygen in exercise as at rest, and produce the same increase in CO2.
