    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： 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.
