Safe standby mode for ventilator
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.
1. A ventilator comprising:
a processor; and
a memory storing computer-readable instructions that when executed by the processor cause the ventilator to:
deliver ventilation to a patient according to a normal mode of ventilation;
receive an indication to initiate a standby mode of ventilation;
receive a confirmation of the indication to initiate the standby mode of ventilation;
disable at least one patient disconnect alarm;
monitor for disconnection of the patient from the ventilator;
when disconnection of the patient occurs within a period of time, discontinue ventilation to the patient according to the normal mode of ventilation.
2. The ventilator of claim 1 , the computer-readable instructions when executed by the processor further causing the ventilator to:
monitor for reconnection of the patient to the ventilator.
3. The ventilator of claim 2 , the computer-readable instructions when executed by the processor further causing the ventilator to:
in response to detecting reconnection of the patient to the ventilator, automatically resume the ventilation to the patient according to the normal mode of ventilation.
4. The ventilator of claim 3 , the computer-readable instructions when executed by the processor further causing the ventilator to:
store ventilator settings for use in the normal mode of ventilation; and
automatically resume the normal mode of ventilation based on the stored ventilator settings.
5. The ventilator of claim 1 , the computer-readable instructions when executed by the processor further causing the ventilator to:
deliver gases at a reduced rate during the standby mode of ventilation.
6. The ventilator of claim 5 , wherein delivering the gases at the reduced rate enables the ventilator to detect reconnection of the patient to the ventilator.
7. The ventilator of claim 1 , the computer-readable instructions when executed by the processor further causing the ventilator to:
when disconnection of the patient does not occur within the period of time, continue ventilation to the patient according to the normal mode of ventilation.
8. The ventilator of claim 1 , the computer-readable instructions when executed by the processor further causing the ventilator to:
provide a prompt for receiving confirmation of the indication to initiate the standby mode of ventilation.
9. A method implemented by a ventilator, the method comprising:
receiving an indication to initiate a standby mode of ventilation;
receiving a confirmation of the indication to initiate the standby mode of ventilation;
disabling at least one patient disconnect alarm;
monitoring for disconnection of the patient from the ventilator;
when disconnection of the patient occurs within a period of time, discontinuing ventilation to the patient according to a normal mode of ventilation.
10. The method of claim 9 , further comprising:
monitoring for reconnection of the patient to the ventilator.
11. The method of claim 10 , further comprising:
in response to detecting reconnection of the patient to the ventilator, automatically resuming ventilation to the patient according to the normal mode of ventilation.
12. The method of claim 11 , further comprising:
storing ventilator settings for use in the normal mode of ventilation; and
automatically resuming the normal mode of ventilation based on the stored ventilator settings.
13. The method of claim 9 , further comprising:
delivering gases at a reduced rate during the standby mode of ventilation.
14. The method of claim 13 , wherein delivering the gases at the reduced rate enables the ventilator to detect reconnection of the patient to the ventilator.
15. The method of claim 9 , further comprising:
when disconnection of the patient does not occur within the period of time, continue ventilation to the patient according to the normal mode of ventilation.
16. The method of claim 9 , further comprising:
providing a prompt for receiving confirmation of the indication to initiate the standby mode of ventilation.
17. A ventilator comprising:
a processor; and
a memory storing computer-readable instructions that when executed by the processor cause the ventilator to:
deliver ventilation to a patient according to a normal mode of ventilation;
receive an indication to initiate a standby mode of ventilation;
receive a confirmation of the indication to initiate the standby mode of ventilation;
disable at least one patient disconnect alarm;
monitor for disconnection of the patient from the ventilator;
in response to determining whether disconnection of the patient occurs within a period of time, perform one of:
discontinue ventilation to the patient according to the normal mode of ventilation; or
continue ventilation to the patient according to the normal mode of ventilation.
18. The ventilator of claim 17 , when disconnection of the patient occurred within the period of time, the computer-readable instructions when executed by the processor further causing the ventilator to:
monitor for reconnection of the patient to the ventilator.
19. The ventilator of claim 18 , the computer-readable instructions when executed by the processor further causing the ventilator to:
in response to detecting reconnection of the patient to the ventilator, automatically resume the ventilation to the patient according to the normal mode of ventilation.
20. The ventilator of claim 17 , the computer-readable instructions when executed by the processor further causing the ventilator to:
deliver gases at a reduced rate during the standby mode of ventilation.
21. The ventilator of claim 20 , wherein delivering the gases at the reduced rate enables the ventilator to detect reconnection of the patient to the ventilator.
