ABSTRACT:
System and method of monitoring a patient including acquiring a respiration waveform and an arterial pressure waveform and determining a window on the respiration waveform that represents end expiration and approximates an apnea condition. The method can include calculating a systolic pressure variation value, a delta up value, and a delta down value based on a portion of the arterial pressure waveform corresponding to the window on the respiration waveform. In some embodiments, the respiration waveform can be acquired without manual interruption of mechanical ventilation and the values can be calculated substantially continuously.
