A ventilator for ventilating a patient has means integrated therewith for carrying out a determination of the functional residual capacity of the patient using an inert gas wash in / wash out technique. To this end, the ventilator operates to alter the inert gas content of breathing gases provided to the patient. The amount of inert gas expired by the patient is obtained and used to determine functional residual capacity on a breath-by-breath basis. A graph of the functional residual capacities for a given number of breaths is produced. Thereafter, the inert gas levels in the breathing gases are returned to the original levels and further functional residual capacity determinations and a graph of same provided. The functional residual capacity information may also be provided in tabular form. A log of functional residual capacity determinations and ventilator settings or patient treatments affecting same may also be provided.

A methodology and apparatus for determining ventilator settings including an end expiratory pressure setting, pressure swing, resistive unloading and target ventilation for delivering ventilatory support based upon generalized patient ventilation characteristics and / or disease classifications. An apparatus may be programmed with the instructions to accomplish the methodology interactively by prompting the user / physician during setup and calculating settings based upon measurements or input responses. Pre-assigned values associated with ventilation characteristics or disease classifications may be combined with a base pressure value or measured values to provide patient customized settings or adjustments to determine pressure levels for the delivery of ventilatory support.

An airway device is provided that may track the flow of respiratory gases through the device with sensing elements at a plurality of locations along the gas flow path of the device. Such a device may be useful for assessing a variety of clinical states, for adjusting patient ventilator settings, or for determining whether or not an airway device has been properly inserted into a patient airway.

A method and apparatus for determining suitable settings for a servo-ventilator to be used during sleep. Respiratory characteristics of a patient are measured during an awake learning period. With these measured characteristics, a target ventilation setting may be calculated by alternative methods. The calculated setting may then be used for enforcing a minimum ventilation during a treatment period where ventilatory support is provided with a servo-controlled ventilator.

A ventilator system is capable of displaying complex information patterns in a GUI, thereby allowing a clinician to get subtract complex information from multiple parameters inputs.

An input device for a clinician to control and modify the operation of a mechanical ventilator comprises a graphical display, a representation of a respiratory therapy trajectory to be delivered to a patient, at least one data point associated with the trajectory, and a data input means for the clinician to select a data point and to modify the value of the trajectory at that data point. The present invention provides for the creation and modification of a respiratory therapy trajectory, wherein the ventilator provides a medical gas waveform to a patient according to the respiratory therapy trajectory.

Various embodiments of the present disclosure provide systems, methods and devices for respiratory support. As one example, a ventilation system is disclosed that includes a computer readable medium including instructions for operating in a hybrid mode. These instructions include measuring patient effort during a spontaneous breath type and deriving a neural inspiratory time from the measurements of patient effort. This neural inspiratory time is then set as the inspiratory for a breath of a mandatory breath type. If new patient effort measurements are received by the ventilator, the neural inspiratory time may be adjusted.

The invention relates to a mechanical ventilation system for respiration of a patient, the system being adapted for providing decision support for mechanical ventilation. Control means is adapted for using both first data and second data, indicative of the respiratory feedback in the blood, in physiological models (MOD) descriptive of, at least, lung mechanics, and / or gas exchange in the lungs of the patient, the physiological models comprising a number of model parameters (MOD_P). The control means is further arranged for simulating the effect on one, or more, model parameters (MOD_P) of the physiological models for a suggested value of the positive end expiratory pressure (PEEP) setting for the ventilation means, and thereby provide decision support in relation to said suggested PEEP value. The invention is advantageous for providing mathematical based models of changes in physiology in response to changes in ventilator settings of the PEEP thereby allowing mathematical physiological models to predict changes in clinical variables for a given value of PEEP.
