Problems solved by technology

[0008] A problem associated with the method disclosed by Bellani et al. is that it relies on expiratory blocking operations
[0010] A problem associated with the method disclosed in Sinderby is that it requires the determination of the electrical activity of the patient's respiratory muscles during periods of no breathing assistance (zero assistance)
Therefore, the method cannot always be performed while ensuring proper ventilation therapy for the patient

Embodiment Construction

[0052] A respiratory device and an associated method for automatically and dynamically determining at least one physiological parameter, including neuromechanical efficiency (NME), of a patient being ventilated by the respiratory device will now be described with reference to exemplary and non-limiting embodiments.

[0053] figure 1 A breathing device 1 for the mechanical ventilation of a patient 3 is shown, for example a ventilator or anesthesia machine. The breathing apparatus 1 is connected to the patient 3 via an inspiratory line 5 for supplying breathing gas to the patient 3 and an expiratory line 7 for delivering expiratory gas away from the patient 3 . The inspiratory line 5 and the expiratory line 7 are connected via a so-called Y-piece 11 to a common line 9 which is connected to the patient 3 via a patient connector 13 such as a mask or an endotracheal tube.

[0054] The respiratory device 1 also comprises a control unit or control computer 15 for controlling the ven...

Abstract

The present disclosure relates to a method, computer program and breathing apparatus for determination of at least one physiological parameter including the neuromechanical efficiency [NME] of a patient (3) being mechanically ventilated by the breathing apparatus (1). This is achieved by obtaining (S2, S4) samples of an airway pressure (Paw), a patient flow ( ), a change in lung volume(V) caused by the patient flow, and an electrical activity of a respiratory muscle of the patient (3),during ventilation of the patient at a first level of ventilatory assist and a second and different level of ventilatory assist, and determining (S5) the at least one physiological parameter, including NME, from the airway pressure samples, the patient flow samples, the samples of the change in lung volume, and the samples of the electrical activity of the respiratory muscle, obtained at the different levels of ventilatory assist.

Description

technical field [0001] The present invention relates generally to the field of mechanical ventilation. More specifically, the present invention relates to a respiratory apparatus, method and computer program for determining physiological parameters including neuromechanical efficiency (NME) of a mechanically ventilated patient. Background technique [0002] Mechanical ventilation can be used to provide ventilatory assistance to spontaneously breathing patients, for example by means of a mechanical ventilator. [0003] In recent years, techniques have been developed for neuromodulation of ventilation, i.e., by controlling the supply of breathing gas to the ventilator based on at least the point in time at which the patient desires to inhale and / or exhale. The technique of adapting the patient's ventilation pattern to the patient's breathing effort. An example of such a technology is the now clinically established Neuro-Adjusted Ventilatory Assist (NAVA) technology. [0004...
