Bernoulli is a powerhouse when it comes to clinical decision support. Our proficiencies in real-time data acquisition, manipulation, and application are patent protected making Bernoulli unlike any other system. To help explain how the system works, let’s look at an example where Bernoulli detects consecutive patient events and sends an early warning alert to a caregiver. Jill is a 32-year old female patient that has been involved in a car crash and is currently on a ventilator in the Intensive Care Unit. She has respiratory trouble. Each time she coughs it forces the high peak pressure on the ventilator to alarm and send a notification to the nurse. These episodes typically self-correct and a nurse does not need to intervene. However, if Jill has three or more coughing spells within a one-minute increment the nurse would like a notification. A parameter is set within the Bernoulli system to detect these consecutive events. When they occur, the system then generates a new type of alarm – a smart alarm – which helps to prevent deterioration and protect the patient.
The most common Bernoulli smart alarms include:
- Limit Alarms – Occur when a given value (patient measurement) violates either an upper or lower limit (e.g. HR > 140, or HR exceeding 140 bpm)
- Trend Alarms – Occur when a given value (patient measurement) violates an upper or lower percentage compared with the average value (normal) for a patient
- Combination Alarms – Occur when two values (patient measurement) violate their limits, either high or low simultaneously
- Consecutive Alarms – Occur when a value (patient measurement) goes in and out of a limit violation a given number of times, over a specific time period
- Sustained Alarms – Occur when a value (patient measurement) violates a specified threshold for a minimum time period
- Setting change – Identified as changes to a saved setting on a limit threshold, such as a change in bradycardia or tachycardia threshold.
- Smart ranked alarms – Alarms are ranked based upon whether they meet criteria for urgency or warning. These alarms can be displayed on the dashboard according to the level by which they exceed specific thresholds (urgent, warning)
- Advanced Algorithms – A set of rules that are more complex than simply comparing a parameter with a given threshold and reporting on a deviation. Further, using advanced rules, the system creates complex mathematical relationships and studies parameter behaviors to create a set of instantiated rules that can then be built into the operational portion of the platform for live use.
