A blood gas monitoring system monitors blood gas from blood in a blood vessel. A blood probe is introduced into the blood vessel. The blood probe includes a probe body defining a probe chamber and a first gas permeable membrane coupled to a first end of the probe body. A sensor is provided proximate a second end of the probe chamber to sense a desired characteristic of the blood gas. Blood gas is allowed to diffuse across the first gas permeable membrane and into the probe chamber so that the blood gas in the probe chamber is substantially in equilibrium with the blood gas in the blood vessel. Once blood gas in the probe chamber has substantially equilibrated with the blood gas in the blood vessel, the desired characteristic of the blood gas is sensed. |
