Abstract
A system for the control of a ventilator or an anesthesia delivery machine for an intubated patient, wherein the intubated patient has an endotracheal tube inserted into the airway passage, the endotracheal tube having a controllably inflatable annular cuff thereon, wherein the cuff is monitored and controlled by a pressure control unit, the system including: a patient-disturbed signal arrangement for providing a feedback to the ventilator or anesthesia delivery machine through the pressure control unit to delay pressure changes directed to the cuff by the ancillary devices.
Claims20
An endotracheal tube or tracheostomy tube monitoring and control system for the safe and effective use of a pressurizable annular cuff about the distal end of that tube arranged within the larynx or trachea of a human patient comprising:
- a control unit for the monitoring and control of the tube cuff in communication therewith;
- a pressure sensor in communication with the control unit and with an empowered air pump and associated a dump valve;
- and
- a feedback circuit connected to an ancillary device supporting the patient, so as to control time and pressure responsive use of the ancillary device relative to pressure changes in the tracheal cuff in the patient.
A method to control ancillary devices supporting a patient having an endotracheal tube inserted within the patient's trachea, the method comprising:
- a system controlled by a control unit, which unit controls timed pressure intervention in a cuff on the tracheal tube;
- a delay arrangement within the control unit to delay an decrease in pressure in the cuff in response to a signal received by the control unit, so as to avoid pressure changes responsive to temporary increases in cuff pressure to prevent pressure change operation of ancillarily connected devices.
A method for monitoring and controlling use of an endotracheal or tracheal tube cuff in a patient's trachea of a patient lying in a bed, comprising:
- attaching a pressurized line to a tube cuff for engaging the patient's trachea;
- monitoring and controlling the pressure in the cuff in the patient by a monitor and control system;
- limiting the pressure in the cuff to about 45 inches of water;
- sounding a patient monitoring alarm by the system, to remind a patient assist personnel to check and cleanse the patient's airway;
- sounding a patient monitoring alarm by the system, if the angle of the bed is less than about 30 degrees from horizontal;
- overriding control from the microprocessor by the safety pressure relief switch in response to a received danger signal, should cuff pressures rise to dangerous levels;
- and
- controlling ancillary devices from introducing pressure increases into the cuff.
