Embodiment Construction
[0040] figure 1 A patient monitoring system 1 according to the invention is illustrated. Monitoring system 1 as described suppresses false positive apnea alarms related to respiration (eg caused by motion artifacts or noise signals) by using the patient's invasive blood pressure signal as an alternative parameter.
[0041] The system 1 comprises a plurality of measuring electrodes 2 adapted to perform impedance respiration measurements to obtain a respiration signal 10 corresponding to the patient's respiration, see figure 2 . The system 1 also comprises a measurement device 3 for sensing the patient's invasive blood pressure (PAP) 11, and an SpO for acquiring the patient's plethysmographic signal (PAP) 12. 2 A sensor 4 , the signal corresponding to the pulsation of the patient's blood at said sensor measurement point, and an ECG sensor 5 for measuring the ECG signal 13 . All signals, the PAP signal 11, the plethysmographic signal 12, and the ECG signal 13 include respirat...
