Patent number: 5836302Abstract: An audible waveform system is provided that senses a parameter relating to the ventilation of a patient. The system produces short bursts of sound of a predetermined frequency as the changes occur in that parameter based on certain increments of change. The bursts themselves are preferable at a frequency that is the same for equal pressures but increases and decreases in frequency as the parameter increases or decreases, respectively. In the preferred embodiment, the system provides an audible waveform based on the pressure in the patient airway so that the clinician can receive information relating to that waveform conveniently and without taking attention away from other monitors and/or alarms.Type: GrantFiled: July 10, 1997Date of Patent: November 17, 1998Assignee: Ohmeda Inc.Inventors: James R. Homuth, Kevin G. Tissot

Patent number: 5765554Abstract: A control system where the clinician can have manual control of the state for various alarms, generally volume alarms and apnea alarms. The control is interactive, that is, while the clinician can manually set the state in a variety of settings, the control system automatically overrides the clinician's selection to activate both the volume and apnea alarms wherever the mechanical ventilator is turned on. In addition, there is another override where a breath is detected by the ventilator to turn all of the alarm systems from both being inactive to both alarms being active.Type: GrantFiled: March 29, 1996Date of Patent: June 16, 1998Assignee: Ohmeda Inc.Inventors: Steven K. Somerson, Kevin G. Tissot, James R. Homuth

Patent number: 5673688Abstract: A system is provided for detecting the breakthrough of CO.sub.2 into the inspiratory limb of a substantially closed circle patient breathing circuit having a CO.sub.2 absorber to remove CO.sub.2 from the continuously recirculating gases. The CO.sub.2 is detected by a gas analyzer located in the inspiratory limb of the patient breathing circuit. Upon detection of that CO.sub.2, the system increases the flow of fresh gas into the circle patient breathing circuit to a flow rate in excess of the minute volume of gas being delivered at that time to the patient. The increased flow of fresh gas basically prevents the further flow of CO.sub.2 from the expiratory limb into the inspiratory limb, thus preventing the CO.sub.2 from being inhaled by the patient.Type: GrantFiled: September 26, 1996Date of Patent: October 7, 1997Assignee: Ohmeda Inc.Inventors: Robert Q. Tham, James R. Homuth

Patent number: 5669379Abstract: An algorithm is disclosed that enables the display for a medical ventilator to automatically adjust its wave characteristics depending on the settings for that ventilator established by the clinician. As the respiratory rate, or rate at which the ventilator provides breaths to the patient, is changed by the user, the rate of sweep of the waveform generator displaying that data is also changed to insure that the data is displayed in the most relevant manner. As another parameter, as the pressure limit in the patient circuit is set by the clinician, the waveform vertical scale is adjusted to make sure the particular limit of pressure is displayed. As the pressure limit or the respiratory rate are changed in the ventilator by the clinician, the waveform of he data displayed also is automatically modified to make that data best presentable to the clinician.Type: GrantFiled: March 29, 1996Date of Patent: September 23, 1997Assignee: Ohmeda Inc.Inventors: Steven K. Somerson, Kevin G. Tissot, James R. Homuth
