Safe standby mode for ventilator
First Claim
Patent Images
1. A method for controlling a ventilator, comprising:
- connecting a patient to a ventilator;
initiating ventilation of the patient using the ventilator using first ventilation settings;
after initiating ventilation of the patient using the ventilator, receiving a safe standby mode selection from a user via a user interface to enter a safe standby mode;
in response to receiving the safe standby mode selection;
starting a timer;
disabling at least one patient disconnect alarm; and
continuing ventilation of the patient using the first ventilation settings;
receiving a confirmation selection from the user via the user interface confirming the safe standby mode selection;
detecting that the patient is disconnected from the ventilator;
in response to receiving the confirmation selection and the detection that the patient is disconnected from the ventilator prior to the timer reaching a predetermined value;
discontinuing ventilation of the patient; and
entering the safe standby mode; and
while in the safe standby mode, continuing to disable the at least one patient disconnect alarm and monitoring for a connection of the patient to the ventilator.

Abstract
A ventilator with a safe standby mode is provided. The safe standby mode allows a user to disconnect a patient from the ventilator, without the ventilator generating alarms and while maintaining previously entered ventilation parameters. In addition, while in the safe standby mode, a patient connection status is monitored, and a ventilation mode is entered automatically if the ventilator determines that a patient is connected to the ventilator while the ventilator is in the safe standby mode.

9. A method for controlling a ventilator, comprising:
-
connecting a patient to a ventilator; initiating ventilation of the patient using the ventilator; after initiating ventilation of the patient using the ventilator, detecting that the patient has become disconnected from the ventilator; upon detecting that the patient has become disconnected from the ventilator, providing a user interface output that allows the user to select via the user interface a safe standby mode; in response to a user selection via the user interface to enter the safe standby mode, performing, based on a when the user selection occurred and when the disconnection was detected, one of; entering the safe standby mode, wherein while in the safe standby mode a disconnect alarm is not generated;
orentering a disconnect mode, wherein while in the disconnect mode a disconnect alarm is generated. - View Dependent Claims (10, 11, 12, 13)

14. A ventilation system, comprising:
-
a user output, the user output adapted to provide a selection of a safe standby mode; a user input interconnected to a controller, the user input adapted to receive a safe standby mode selection via a user interface selecting the safe standby mode and a subsequent confirmation selection via a user interface confirming the safe standby mode selection; a breathing gas supply interconnected to and operated in response to instructions from the controller; a patient circuit interconnected to the breathing gas supply; a patient breathing apparatus interconnected to the patient circuit; a return flow transducer interconnected to the patient circuit; a controller interconnected to the user output, the user input, and the breathing gas supply, the controller adapted to; receive a signal from the user input that the safe standby mode selection has been made; receive a signal from the user input that the confirmation selection has been made; enter the safe standby mode upon receiving the signal from the user input that the safe standby mode selection has been made and the signal from the user input that the confirmation selection has been made; while in the safe standby mode of operation, maintain ventilation of the patient using current ventilator settings and monitor a connection status of the patient breathing apparatus; detect that a patient is connected to the ventilator; and after detecting that a patient is connected to the ventilator, resume ventilation of the patient using the current ventilator settings. - View Dependent Claims (15, 16)
