Abstract: A ventilator includes electronic control circuitry configured to control a supply of breathing gas for a plurality of respiratory cycles, measure a volume received by the patient in each of the plurality of respiratory cycles, and determine, for each cycle of the plurality of respiratory cycles, a cycle score corresponding to a deviation between the volume of the cycle and a predetermined target volume. The determined cycle score can be selected from a predetermined number of cycle scores that span positive and negative numbers based on the deviation. A pressure step value can be determined based on a plurality of cycle scores corresponding to the plurality of respiratory cycles, and a current pressure of the breathing gas is adjusted by an amount corresponding to the determined pressure step value. The pressure step value may be generated by dividing a sum of the plurality of cycle scores by a sample size.

Abstract: A method for controlling mechanical lung ventilation is described. The method may include intermittently switching the airway pressure of a patient from a first baseline pressure level to a second baseline pressure and vice-versa such that the patient is able to breathe spontaneously in both first and second baseline pressure levels; detecting an inspiration effort by the patient within a predetermined period of time before a switching event of the intermittently switching the airway pressure; and controlling, responsive to detecting a breathing effort, a flow control valve and an exhalation valve to adjust a length of the first period of time according to a delay time so a patient inspiration-exhalation cycle is completed prior to the switching event.

Abstract: A method for controlling mechanical lung ventilation is described. The method may include intermittently switching the airway pressure of the patient from a substantially constant high baseline pressure level to a substantially constant low baseline pressure and vice-versa such that the patient is able to breathe spontaneously in both high and low baseline pressure levels; detecting an inspiration effort by the patient inside a trigger time window that immediately precedes a switching event of the intermittently switching the airway pressure; maintaining a baseline pressure at the level in which the inspiration effort was detected so that the patient can complete the inspiration-exhalation cycle; and switching the baseline pressure level after a delay time.

Abstract: A method for controlling mechanical lung ventilation is described. The method may include supplying a breathing gas to an airway of a patient in an intermittent way such that a plurality of respiratory cycles are formed; measuring a volume received by the patient in one or more respiratory cycles of the plurality of respiratory cycles; comparing the measured volume of each of the one or more respiratory cycles with a user defined target volume; attributing a classifying score to each of the one or more respiratory cycles based at least partially on a deviation between the measured volume and the user defined target volume; summing the classifying scores and dividing the result by a sample size of the one or more respiratory cycles; attributing a pressure step value based at least partially on the division result; and adding the pressure step value to a present pressure.

Abstract: The present invention refers to a lung ventilation device fitted with a patient monitoring and surveillance graphical interface comprising technical and functional characteristics that can reduce the cognitive load of the medical staff members in environments whose monitored beds require safe and efficient surveillance, principally for the identification and detection of parameters that are monitored at distance. More particularly, the present invention comprises a graphical interface whose configuration allows visualization at distance and interpretation of the main parameters associated with the patient, as well as includes means for facilitating the detection of the occurrence of critical alarms, even by an operator away from the patient.
