Hemoglobin-oxygen equilibrium curve analyzer |
abstract |
A system for obtaining a hemoglobin-oxygen equilibrium curve for a sample of concentrated hemoglobin solution or whole blood. Gaseous oxygen and/or nitrogen is used to oxygenate or deoxygenate the sample. The exchange takes place across a gas-receiving cup-shaped semipermeable membrane in a temperature-controlled chamber containing the sample, in an annular space defined between the cup-shaped gas-receiving membrane and the chamber wall. The rate of oxygen transport into and out of the sample is continuously calculated by means of a microcomputer. Simultaneously the solution pO 2 is measured by means of a Clark electrode exposed to the sample. From the oxygen transport rate calculation and the pO 2 measurement, the percent O 2 saturation is calculated and is plotted against the change in pO 2 . Oxygen can be exchanged bidirectionally with the sample across the semipermeable membrane, which is positioned concentrically in a cylindrical sample cavity. The sample solution is maintained well-stirred by a magnetic stirrer provided in the cavity. |
