  • Patent number: 8312879
    Abstract: A method for controlling a mechanical ventilator that is supplying medical gas to a patient via an endotracheal tube. A pressure is measured from a patient end of an endotracheal tube. The pressure at the patient end of the endotracheal tube is used to create an improved endotracheal tube resistance model such that the medical gas supplied by the mechanical ventilator may be compensated for the resistance of the endotracheal tube thereby providing increased control over the medical gas that is delivered to the patient's lungs. Additionally, if an obstruction in the patient's airway is detected, the location of the obstruction may be targeted such that the proper remedial treatment or procedure is selected by a clinician.

  • Publication number: 20080295837
    Abstract: A method and system for ventilating a patient that compensates for leaks occurring within the patient breathing circuit while limiting the volume of breathing gas delivered to the patient. During the operation of a ventilator to supply breathing gases to a patient, the ventilator monitors for leak volumes occurring during the inspiratory phase and expiratory phase of the breathing cycle. Based upon the leak volumes sensed, the volume of breathing gas delivered by the ventilator is increased such that the tidal volume delivered to the patient is the desired tidal volume set by a clinician. The ventilator operates to generate a leak alarm when the leak volume exceeds an alarm threshold. If the leak alarm is generated, the tidal volume delivered to the patient is limited to the tidal volume being delivered prior to generation of the leak alarm.

  • Publication number: 20080091117
    Abstract: A ventilator for ventilating a patient also assists a clinician in determining a suitable PEEP for the patient. For this purpose, a graph or tabular display of a series of different value PEEPs and corresponding functional residual capacities of the patient may be provided. Or, the relationship between lung compliance and a series of different values of PEEP may be provided. Or, the amount of the lung volume recruited/de-recruited at various levels of PEEP may be determined for use in selecting a desired PEEP. To this end, the functional residual capacity of the lungs is determined for a first PEEP level. The PEEP is then altered to a second level and a spirometry dynostatic curve of lung volume and pressure data is obtained. The lung volume on the dynostatic curve at a lung pressure corresponding to the first PEEP value is obtained.

  • Patent number: 6371113
    Abstract: An improved system for making an accurate determination of the patient's compliance and airway resistance by ensuring that the flow to and/or from the patient at the end of a ventilator pause is, in fact, reduced to zero flow. The normal ventilator pause occurs at the end of an inspiratory cycle where the ventilator terminates the breathing air delivery to the patient and then enters a pause period. Values are taken for the airway flow and pressure at the beginning of the pause period, that is at peak pressure, and a second set of readings is taken at the end of the pause period, called the plateau pressure. This second set of readings greatly simplifies solving the equations for patient resistance and compliance if the flow at that time is assumed to be zero.

  • Patent number: 6125848
    Abstract: A system that enables the accurate monitoring of tidal volume of a patient when using a Bain, Mapleson D or similar type of patient breathing circuit in an anesthesia system. The system allows the use of flow sensors positioned at the machine or distal end of the patient breathing circuit and not at the less desirable patient or proximal end of the patient breathing circuit. Thus, the flow sensors can be positioned out of the way of the patient and will provide a measurement of the tidal volume of the patient. A CPU is used to take into account, the additional fresh gas provided to the patient breathing circuit during the expiration cycle to correct the flow monitored in the main breathing tube that supplies the gas to the patient from a ventilator or breathing bag.

  • Patent number: 6119686
    Abstract: An apnea detection system is disclosed for use with a medical ventilator and which detects the volume of gas delivered by the ventilator to a patient and also the volume of gas exhaled by the patient. The two flow measurements are compared, preferably in a microprocessor, to determine whether an apnea condition exists by comparing, against a known standard, the two detected volumes. The volume of the exhaled gas must be a predetermined percentage of the volume of gas delivered to the patient within a predetermined time period or an alarm is activated indicating an apnea condition.

  • Patent number: 5735267
    Abstract: A control system for a single-valve controlled medical ventilator adaptively invokes separate flow delivery or flow exhaust control functions in response to the sensed dynamic state of the ventilator without any dependence on measured patient parameters. The control system selects either the flow delivery control system or flow exhaust control system based on a determination of the mode in which the ventilator is operating. The determination is made using a sensed ventilator operational parameter, such as the ratio of manifold pressure to flow output, to select the appropriate control function. A hysteresis routine is provided to prevent "hair triggering" between the flow delivery and flow exhaust control systems.

  • Patent number: 5662099
    Abstract: An improved system for the determining the collapse of a bellows within a canister as part of a ventilator system for delivering breaths to a patient via a patient circuit. The system measures the pressure in the bellows canister external of the bellows and measures the pressure within the interior of the bellow. A processor compares the pressures and determines when the pressure within the canister exceeds a predetermined offset in excess of the pressure within the interior of the bellows to conclude that the bellows is in a collapsed condition. In the preferred embodiment, the processor also uses, as input data, the flow delivered by the ventilator to the bellows canister to determine that offset value. When a bellows empty condition is determined, various actions can be taken, among them to signal an alarm and also to change various functions of the ventilator to prevent further difficulties in the overall system.

  • Patent number: 5651360
    Abstract: An improved system for the control of PEEP in a medical ventilator system having a ventilator and a bellows contained within a bellows canister. A pop-off valve that normally vents excess pressure within the bellows to atmosphere is modified such that its exhaust is vented to a predetermined pressure above atmospheric pressure, such as the PEEP pressure. In the preferred embodiment, that predetermined pressure is the pressure within the ventilator drive gas conduit that transmits the gas from the ventilator to drive the bellows and the exhaust from the pop-off is effectively isolated from that drive gas conduit to avoid contaminating the gas within that drive gas conduit.

  • Patent number: 5303698
    Abstract: A medical ventilator is provided for providing continuous, closed-loop control of the pressure of gas within a patient's mouth or respiratory tract in accordance with any selected pressure input waveform. The medical ventilator comprises an adaptive, feedback controller which provides independent control of the inspiratory and expiratory branches of the ventilator, while continuously controlling mouth pressure. The digital coefficients of the controller are updated to adjust for variations in the resistance of the patient's respiratory tract resulting from the magnitude of flow of inspiratory gas into the tract and patient-to-patient differences. Pressure in the expiratory branch is controlled by controlling, through a pressure-regulating valve, the magnitude of back pressure applied to a diaphragm valve. A venturi provides a reference pressure for the pressure-regulating valve below that of the surrounding atmosphere to enable application of a negative back pressure to the diaphragm valve.
