What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 are studying whether a machine-learning monitor can predict low blood pressure episodes in patients having lung surgery with one-lung ventilation. The study enrolls about 77 adults scheduled for lobectomy or pneumonectomy. During surgery, the team records standard blood pressure data alongside readings from the HemoSphere monitor with Hypotension Prediction Index software, then checks how well the software's alerts match actual drops in blood pressure.

What this could mean

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

Active substance
HemoSphere monitor with Acumen Hypotension Prediction Index software
What this could lead to
If the software predicts low blood pressure accurately in lung surgery, anesthesiologists could intervene earlier and reduce complications tied to drops in blood pressure during these operations.
What could go wrong
This is a small observational study in one type of surgery, so the software may perform differently in other patients or settings. It does not test whether acting on the alerts actually prevents complications.

Who is studied

60 consecutive adult patients qualified for open-chest lung resection procedures under general anesthesia and one-lung ventilation will be monitored during the operation using standard invasive hemodynamic monitoring with arterial pressure transducer and concomitantly with HemoSphere monitor with the HPI software attached to the Acumen IQ transducer (Edwards LifeSciences, Irvine, CA, USA).
