Validation of a Connected Patch, an Alternative to Conventional Monitoring
Study Details
Study Description
Brief Summary
The hypothesis is that this connected patch could be used in surgical departments to detect early a cardiovascular or respiratory complication and therefore to treat it without delay. However, it has not been validated in a hospital setting; that is the purpose of this project. This step of validating the connected monitoring object is required in different places: post-interventional surveillance room that approaches a conventional hospital room, and operating room where artifacts are numerous. Validation will be done by comparing data from General Electric's conventional monitors, with data from patches.

Detailed Description
When patients operated on outside intensive care or intensive care units are hospitalized, vital signs are collected intermittently by various conventional devices. During the follow-up period of these patients, it is possible that abnormal vital signs that may identify clinical deterioration may appear a few minutes to a few hours before a serious adverse event (infection etc.) occurs. These signals often go unnoticed due to infrequent monitoring.
The establishment of teams to ensure a rapid response would improve the safety of hospitalized patients for whom the detection of abnormal vital signs predictive of clinical deterioration would generate an alarm. This system is based on the identification of patients at risk and the rapid intervention of the team.
One of the crucial issues is therefore the speed of the alarm and its reliability.
The evolution of electronic technology offers the possibility of using inexpensive portable devices (connected patches) that can provide information on vital signs in real time. Vital signs collected by these devices could be analyzed to predict clinical deterioration prior to hospital staff visits, especially at night and on weekends when staffing levels are generally lower.
The connected patch used in this research is the Devinnova company's device "myAngel VitalSigns". The long-term objective would be to be able to use this connected patch in surgical departments to detect early a complication, particularly of a cardiovascular or respiratory nature, and therefore to treat it without wasting time. However, it has not been validated in a hospital setting; that is the purpose of the project.
The objective of this research is therefore to validate Devinnova's connected patch in different locations: post-interventional surveillance room that approaches a conventional hospital room, operating room where artifacts are numerous.

- Blood pressure artifact [From beginning of anesthesia to 36 hours]
An artifact is defined as any value that deviates from a physiologically plausible range or by a deviation > 50% from the previous value unless this value is followed by a value equal to ± 25%
- Heart rate artifact [From beginning of anesthesia to 36 hours maximum after the surgery]
An artifact is defined as any value that deviates from a physiologically plausible range or by a deviation > 50% from the previous value unless this value is followed by a value equal to ± 25%
- Respiratory rate artifact [From beginning of anesthesia to 36 hours maximum after the surgery]
An artifact is defined as any value that deviates from a physiologically plausible range or by a deviation > 50% from the previous value unless this value is followed by a value equal to ± 25%
- Arterial oxygen saturation artifact [From beginning of anesthesia to 36 hours maximum after the surgery]
An artifact is defined as any value that deviates from a physiologically plausible range or by a deviation > 50% from the previous value unless this value is followed by a value equal to ± 25%
- Acceptability of connected patch [During the surgery and 36 hours maximum after the surgery]
The patient will be asked to evaluate its acceptance of the sensor using a 4-point Likert scale (from 0 = intolerable to 4 = no problem at all)
