| Acumen HPI-enabled EV1000 screen | Device | Acumen HPI-enabled EV1000 screen record the incidence of intraoperative hypotension |
|
| Measure | Description | Time Frame |
|---|---|---|
| Accurate hypotension prediction of EV1000 system | Analyze the actual incidence of hypotension after HPI alarm more than 85 within 15 min | MAP measurements of each case were recorded every 20 s by the EV1000 system from induction to the end of surgery, assessed up to 1 day. |
| Incidence of intraoperative hypotension | Frequency, duration of intraoperative hypotension, which defined as MAP < 65 mmHg at least 1 min | MAP measurements of each case were recorded every 20 s by the EV1000 system from induction to the end of surgery, assessed up to 1 day |
| Severity of intraoperative hypotension | MAP measurements were recorded every 20 s by the EV1000 system from induction to Time-weighted average mean arterial pressure (TWA-MAP) < 65 mmHg | MAP measurements of each case were recorded every 20 s by the EV1000 system from induction to the end of surgery, assessed up to 1 day |
| Measure | Description | Time Frame |
|---|---|---|
| Hospital stay and ICU stay | The incidence and severity of intraoperative hypotension correlate with patient's hospital stay and ICU stay | Days from admission to discharge, assessed up to 1 month |
| Mortality after surgery |
