WebSep 28, 2024 · Perfusion-limited gas exchange: Gas exchange is limited by the rate of blood flow through the pulmonary capillaries. Gases (e.g., O 2, CO 2, N 2 O) can diffuse freely across the blood-air barrier. The concentration of gases in the plasma will become equal to the concentration in the alveoli before the blood reaches the end of the capillary. WebMost pulse oximeters are accurate to within 2% to 4% of the actual blood oxygen saturation level. This means that a pulse oximeter reading may be anywhere from 2% to 4% higher or lower than the actual oxygen level in arterial blood. A number of factors can impair the functioning or accuracy of a pulse oximeter. pennant hills baptist church
