What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

Researchers at GE Healthcare are testing an investigational system that aims to estimate blood pressure changes using SpO2 data, which is typically measured with a finger sensor. The study will enroll 50 adults in intensive care, operating rooms, or recovery areas who already have an invasive blood pressure monitor as part of their care. The goal is to collect data to develop an algorithm that could one day track blood pressure without the need for an arterial line.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
An investigational automated non-invasive blood pressure monitoring system
What this could lead to
If successful, this could lead to a non-invasive way to track blood pressure changes continuously, reducing the need for invasive arterial lines.
What could go wrong
This is an early engineering study with only 50 participants, so the algorithm may not work reliably across all patients or settings. It is not yet a proven clinical tool.
