摘要： A first respiratory volume of the patient is determined during at least a part of the under-assisted breath. A second respiratory volume of the patient is determined during at least a part of the assisted breath, for a duration matching the part of the under-assisted breath. The first and second respiratory volumes may be measured for a same value of a neural respiratory drive of the patient. A volume assistance correction is calculated based on the first and second respiratory volumes. A pressure is measured at the mechanical ventilator or at an airway of the patient. A load of the respiratory system of the patient is calculated based on the volume assistance correction and on the measured pressure. The mechanical ventilator is controlled according to the load of the respiratory system of the patient and may implement a prediction for back-up use when the patient is not spontaneous breathing.

摘要： A method and device determine a level of mechanical ventilatory assist to be delivered to a patient. A patient's neural respiratory drive is measured and multiplied by an existing amplification factor to obtain an existing predicted ventilatory pressure. A mechanical ventilator is controlled accordingly. An existing resulting pressure is measured. The patient's neural respiratory drive is multiplied by a modified amplification factor to obtain a new predicted pressure. The existing and new predicted pressures are compared to determine an anticipated change in pressure. The mechanical ventilator is now controlled according to the new predicted pressure. A new resulting pressure is measured. The existing and new resulting pressures are compared to determine an actual change in pressure. The anticipated and actual changes in pressure are compared. The amplification factor is increased, maintained or decreased in response to the comparison between the anticipated and actual changes in pressure.

摘要： In a method and device for positioning a linear array of electrodes mounted on a distal end section of an elongated flexible member in a patient's respiratory airways at the level of the patient's diaphragm, a length of the elongated flexible member pre-determined to position the linear array of electrodes at the level of the patient's diaphragm is inserted through the patient's respiratory airways. Signals representative of an electrical activity of the patient's diaphragm (EAdi) are detected through the electrodes of the linear array, a presence or absence of ECG signal components is detected in the EAdi signals, and the position of the linear array of electrodes in the patient's respiratory airways is detected in response to the presence or absence of the ECG signal components in the EAdi signals. Also, lower esophageal sphincter activity may be detected in the EAdi signals, and the position of the linear array of electrodes in the patient's respiratory airways determined in response to the detected lower esophageal sphincter. Finally, an end-expiratory occlusion of the patient's respiratory airways may be performed to verify that the electrical activity of the diaphragm coincides with a negative deflection of the patient's respiratory airways pressure again in view of determining adequate positioning of the linear array of electrodes.

摘要： The present invention relates to a method and device for determining a level of ventilatory assist to a ventilator-dependent patient, in which a critical threshold of a respiration-related feature is calculated. Fatigue of a respiratory muscle of the ventilator-dependent patient develops when the critical threshold is reached by the respiration-related feature. The level of ventilatory assist to the ventilator-dependent patient is controlled in relation to the critical threshold of the respiration-related feature so as to prevent fatigue of the patient's respiratory muscle.

摘要： A method and device for determining a level of ventilatory assist to be delivered to a patient by a mechanical ventilator in response to a measure of a patient's neural respiratory drive multiplied by an amplification factor, wherein an existing predicted ventilatory assist pressure is calculated and an existing resulting pressure delivered to the patient by the mechanical ventilator is measured. The amplification factor is changed from an existing amplification factor to a new amplification factor, a new predicted ventilatory assist pressure is calculated using the new amplification factor, and a new resulting pressure delivered to the patient by the mechanical ventilator after the amplification factor has been changed is measured. The new and existing predicted ventilatory assist pressures are compared to determine an anticipated change in pressure that will be delivered to the patient, and the new and existing resulting pressures are compared to determine an actual change in pressure delivered to the patient by the mechanical ventilator. The anticipated and actual changes in pressure are compared and a decision to increase, maintain or decrease the amplification factor is delivered in response to the comparison between the anticipated change and the actual change in pressure.

摘要： A closed loop system uses (a) the intensity of the diaphragm electromyogram (EMG) for a given inspiratory volume; (b) the inspiratory volume for a given EMG intensity; or (c) a combination of (a) and (b); in view of controlling the level of gas flow, gas volume or gas pressure delivered by a mechanical (lung) ventilator. The closed loop ventilator system enables for automatic or manual adjustment of the level of inspiratory support in proportion to changes in the neuro-ventilatory efficiency such that the neural drive remains stable at a desired target level. An alarm can also be used to detect changes in neuroventilatory efficiency in view of performing manual adjustments.

摘要： A ventilatory assist system and method are disclosed. The system comprises a tube for connection to a patient's airway, inspiratory and expiratory tube lumens connected to the tube, an inspiratory air source connected to the inspiration tube lumen, and a controller of air pressure in the expiratory tube lumen. The pressure controller is responsive to a physiological breathing signal representative of patient's inspiratory effort to allow air flow through the expiratory tube lumen during a patient's expiration phase, partially restricting the air flow through the expiratory tube lumen to a so minimum air flow during a patient's inspiration phase. During both respiratory phases, a unidirectional air flow is produced through the inspiratory and expiratory tube lumens to prevent air expired by the patient from being breathed again. The physiological breathing signal allows synchronization of the ventilatory assist with breathing efforts of the patient.
