Catheter systems with blood measurement device and methods are disclosed. An exemplary catheter system for use in positioning a distal end of a catheter body at a desired location in a patient's body may include a needle provided at the distal end of the catheter body to withdraw blood from the patient's body. The needle is fluidically connected to a proximal end of the catheter body. The catheter system may also include a measurement device provided at the proximal end of the catheter body. The measurement device is configured to receive blood withdrawn by the needle for measuring a blood gas value of the blood for use in positioning the distal end of the catheter body at the desired location in the patient's body.
