generating said ventilation harm index based on an analysis of an aggregate of said data, wherein said ventilation harm index comprises a plurality of harm levels indicative of different levels of harm that are expected to occur;

assigning at least one of the plurality of harm levels to the ventilator setting of the ventilator, wherein the at least one of the plurality of harm levels assigned to the ventilator setting is indicative of a level of harm that is expected to occur to a patient associated with the ventilator when operating the ventilator at the ventilator setting;

receiving a selection of the ventilator setting comprising the assigned at least one of the plurality of harm levels;

determining, based on the at least one of the plurality of harm levels assigned to the selected ventilator setting, whether either a verification of the selection of the ventilator setting by a user is required, or a delay of implementation of the ventilator setting is required;

when the determination indicates that the verification, based on the at least one of the plurality of harm levels assigned to the selected ventilator setting, is required, then prompting the user for verification of the selection of the ventilator setting, the prompt comprising an indicator of the at least one of the plurality of harm levels assigned to the selected ventilator setting and receiving a verification of the selection of the ventilator setting from the user;

when the determination indicates that the delay, based on the at least one of the plurality of harm levels assigned to the selected ventilator setting, is required, then delaying implementation of said ventilator setting for a preset duration of time in order to permit the user to cancel implementation of said ventilator setting during the preset duration of time;

implementing the selected ventilator setting on the ventilator upon receiving the verification of the selection of the ventilator setting from the user when the determination indicates that the verification is required; and

implementing the selected ventilator setting on the ventilator after the preset duration of time has passed and when the user does not cancel implementation of said ventilator setting during the preset duration of time when the determination indicates that the delay is required.

2. The method of claim 1, wherein said ventilator setting comprises a time of ventilation or a level of oxygen.

3. The method of claim 1, wherein receiving the verification of the selection of the ventilator setting from the user comprises determining whether the user has authorization to verify the selection of the ventilator setting, and wherein implementing the selected ventilator setting upon receiving the verification of the selection of the ventilator setting from the user comprises implementing the selected ventilator when the determination indicates the user has authorization to verify the selection of the ventilator setting.

4. The method of claim 1,

wherein the plurality of harm levels comprise a low level of harm and a high level of harm, and

wherein the assigned at least one of the plurality of harm levels to the ventilator setting of the ventilator comprises a high level of harm, and

wherein the implementation of said ventilator setting is delayed for a preset duration of time because the assigned at least one of the plurality of harm levels to the ventilator setting of the ventilator comprises a high level of harm.

5. The method of claim 1, wherein at least one of the plurality of harm levels for the patient is assigned to each of a plurality of ventilator settings of the ventilator.

6. A system for prompting a caregiver using a ventilation harm index about potential harm to a patient by implementation of a ventilator setting on a ventilator, comprising:

a memory comprising instructions; and

a processor configured to execute the instructions to;

access data from plurality of ventilators in operation;

generate said ventilation harm index based on an analysis of an aggregate of said data, wherein said ventilation harm index comprises a plurality of harm levels indicative of different levels of harm that are expected to occur;

assign at least one of the plurality of harm levels to the ventilator setting of the ventilator, wherein the at least one of the plurality of harm levels assigned to the ventilator setting is indicative of a level of harm that is expected to occur to a patient associated with the ventilator when operating the ventilator at the ventilator setting;

receive a selection of the ventilator setting comprising the assigned at least one of the plurality of harm levels;

determine, based on the at least one of the plurality of harm levels assigned to the selected ventilator setting, whether either a verification of the selection of the ventilator setting by a user is required, or a delay of implementation of the ventilator setting is required;

when the determination indicates that the verification, based on the at least one of the plurality of harm levels assigned to the selected ventilator setting, is required, then prompt the user for verification of the selection of the ventilator setting, the prompt comprising an indicator of the at least one of the plurality of harm levels assigned to the selected ventilator setting and receive a verification of the selection of the ventilator setting from the user;

when the determination indicates that the delay, based on the at least one of the plurality of harm levels assigned to the selected ventilator setting, is required, then delay implementation of said ventilator setting for a preset duration of time in order to permit the user to cancel implementation of said ventilator setting during the preset duration of time;

implement the selected ventilator setting on the ventilator upon receiving the verification of the selection of the ventilator setting from the user when the determination indicates that the verification is required; and

implement the selected ventilator setting on the ventilator after the preset duration of time has passed and when the user does not cancel implementation of said ventilator setting during the preset duration of time when the determination indicates that the delay is required.

7. The system of claim 6, wherein said ventilator setting comprises a time of ventilation or a level of oxygen.
