Problems solved by technology

[0010] Further, assessment of volume responsiveness based on SVV and / or PVV may not be possible due to the patient's arrhythmic state
[0011] If volume responsiveness is assessed on the basis of parameters that have been judged to be outside the range of practical applicability, there is a serious danger of making a wrong diagnosis that could lead the physician to suggest wrong treatment decisions , there is even a risk of death

Embodiment Construction

[0051] figure 1 The shown device comprises a patient monitor 4 which reads in a pressure signal via an input channel 3 from a pressure sensor 2 which measures the arterial pressure of a patient 6 with an arterial catheter 1 . The patient monitor 4 comprises memory means for storing the curve P(t) of the arterial pressure over time, said curve being determined from the readings of the pressure signal, and the patient monitor also comprises an evaluation unit 7, said evaluation unit is programmed to determine a physiological parameter, such as cardiac output CO, from said pressure curve P(t), and the patient monitor further comprises a display 5 for displaying the physiological parameter.

[0052] The sensor / catheter arrangement 1, 2 may be the same or similar to that already known in conventional patient monitoring systems, in particular patient monitoring systems using pulse wave waveform analysis methods, such as the system under the trademark PiCCO . Additional catheter po...

Abstract

The invention relates to an apparatus and method for determining physiologic parameters of a patient. The apparatus comprises a patient monitor reading in a pressure signal from a pressure sensor measuring an arterial pressure of the patient employing an arterial catheter. The patient monitor can also read in an electrocardiography signal from an ECG device The patient monitor determines curve characteristics indicative for a breathing state and / or a heart rhythm state of the patient and switches from a first volume responsiveness indication state to a second volume responsiveness indication state, if a first condition is met by the curve characteristics, and from the second volume responsiveness indication state to the first volume responsiveness indication state, if a second condition is met. Thus, two visually and / or audibly distinguishable indication states are provided depending on - whether the relevant curve characteristics indicate that the patient is in an arrhythmic condition, and / or - whether the relevant curve characteristics indicate that the patient is breathing spontaneously.

Description

technical field [0001] The invention relates to a device for determining a physiological parameter of a patient. In particular, the invention relates to a device for determining a physiological parameter of a patient, said device comprising at least one pressure sensor device adapted to provide a blood pressure reading of said patient, for storing said reading as at least one pressure dependent A storage device for the temporal profile and an evaluation unit for determining a physiological parameter from the pressure profile. [0002] Furthermore, the invention relates to a method for electronically determining a physiological parameter of a patient, wherein a signal representing blood pressure of said patient is read in, the reading is stored as at least one pressure over time curve, and from said pressure curve Determine physiological parameters. Background technique [0003] Devices and methods of the kind mentioned in the opening part of this application are well known...
