Ventilation arrangement and treatment method

A ventilation arrangement comprising:

• an induction device configured to generate a spatial field having a targeted shape;
• and
• a controller in communication with the induction device and configured to control the induction device to generate the spatial field, wherein
• the induction device is configured to be positioned at a human or animal patient such that, for activating a diaphragm of the patient, a Phrenic nerve of the patient is stimulable by the spatial field generated by the induction device,
• the controller is configured to receive ventilation data about a ventilation of the patient, by being connectable to a ventilation machine to receive the ventilation data about the ventilation of the patient, and
• the controller is configured to evaluate the ventilation data and to operate the induction device in accordance with the evaluated ventilation data,
• wherein the controller is configured to operate the induction device such that trains of the generated spatial field are provided, and wherein each train comprises an increase of an intensity of the spatial field ending at a target intensity of the spatial field.

A method of providing a specific treatment to a human or animal patient, comprising:

• obtaining an induction device configured to generate a spatial field having a targeted shape;
• positioning the induction device at a human or animal patient;
• and
• operating the induction device to stimulate a Phrenic nerve of the patient by the spatial field such that a diaphragm of the patient is activated,
• wherein operating the induction device to stimulate the Phrenic nerve of the patient comprises repeatedly operating the induction device at a repetition rate matched to the specific treatment, comprising a step of defining the repetition rate in accordance with the specific treatment, and
• wherein the specific treatment is:
• prevention of diaphragm muscle loss and/or reduction of risk of ventilator induced diaphragmatic dysfunction, wherein the repetition rate is in a range of about once per day to about 3 times per day, and wherein the stimulation duration is in a range of about 3 minutes to about 20 minutes,
• reduction of risk of developing an acute respiratory distress syndrome or ventilator associated pneumonia or ventilator-induced lung injury or atelectasis, wherein the repetition rate is in a range of about twice per hour to about every two hours, and wherein the stimulation duration is in a range of about 0.5 minutes to about 3 minutes,
• reduction of risk of developing an acute respiratory distress syndrome or ventilator associated pneumonia or ventilator-induced lung injury or atelectasis, wherein the stimulation duration is in a range of about 1 breathing cycle to about 5 breathing cycles, and wherein the repetition rate is in a range of about every minute to about every 30 minutes,
• prevention, delay or replacement of ventilation or reduction of high positive pressures during mechanical ventilation, wherein the repetition rate is at every spontaneous breath of the patient, wherein the stimulation duration is continuously 24 hours a day, and wherein the induction device is operated to stimulate the Phrenic nerve of the patient superimposed in a target rhythm not being synchronous with spontaneous breath of the patient, or
• prevention, delay or replacement of ventilation or reduction of high positive pressures during mechanical ventilation, wherein the repetition rate is, during night time, at every spontaneous breath of the patient, and, during day time, not operating the induction device, and wherein the induction device is operated to stimulate the Phrenic nerve of the patient superimposed in a target rhythm not being synchronous with spontaneous breath of the patient.

A method of providing a specific treatment to a human or animal patient, comprising:

• obtaining an induction device configured to generate a spatial field having a targeted shape;
• positioning the induction device at a human or animal patient;
• and
• operating the induction device to stimulate a Phrenic nerve of the patient by the spatial field such that a diaphragm of the patient is activated,
• wherein operating the induction device comprises providing trains of the generated spatial field, wherein each train comprises an increase of an intensity of the spatial field ending at a target intensity of the spatial field.
