Where we begin

Forced-air warming works.
We want to make it work better.

Our starting point is respect for what the field has built. Decades of clinical experience have made forced-air warming the standard of care for good reason.

Normwell Medical is exploring how the next generation could be quieter in the surgical environment, more responsive to the patient, and useful in more places where patients need warmth.

Sensors are smarter today. Materials are better. Control systems are more precise. We believe the next generation of patient warming can put all of that to work.

Three questions

The questions
guiding our work.

They appear in clinical literature. They come up in operating rooms every day. They shape what we are building toward.

How precisely can warm air be delivered?

01

Warming the patient.
Quietly.

Forced-air warming works by moving heated air to the patient. That principle is sound, and we are designing around it. Our focus is on a question we find interesting: how precisely can the warm air be directed to the patient, and how quietly can the system sit within the surgical environment around it?

We see effective warming and a calm surgical environment as complementary goals, and one of our design priorities is to honor both.

How precisely can warm air be delivered to the patient, and how quietly can warming sit within the OR?

Closing the loop on patient warming?

02

Adapting to
the patient.

Modern medicine has steadily moved toward closed-loop systems. Insulin delivery, ventilation, and anaesthesia have all evolved in that direction.

We are exploring whether closed-loop principles could meaningfully contribute to patient warming, where they could add the most value, and what the right form of that contribution might be. The answer is not predetermined. It is part of what we are working through.

Recent perioperative data continues to suggest that 10 to 14 percent of patients still develop hypothermia, even when active warming is applied. That gap is part of what motivates our work.

Could closed-loop principles meaningfully improve how warmth is delivered to the patient?

Warming, beyond the OR.

What becomes possible?

03

Where the patient is.
Not just where the OR is.

Hypothermia can begin before the first incision: in pre-operative holding, during patient transport, in the back of an ambulance. Forced-air warming is the fastest active warming method available, and pre-warming before surgery has been shown to improve outcomes.

We are exploring how a portable, battery-capable form factor could extend that benefit to more of the perioperative journey, from arrival through recovery.

What becomes possible when forced-air warming can travel with the patient?

Clinical Collaboration

Built with the people
who use it every day.

We are looking for anaesthesiologists, CRNAs, and perioperative nurses who want to be part of this from the beginning, not as survey respondents, but as voices that shape what we build.

Our clinical advisory group is forming now.

Express interest

Clinical Advisory Group

A small group of perioperative specialists with direct influence on product design from the earliest stages.

Named Advisors

Clinicians whose input shapes the product will be publicly acknowledged as Normwell Medical grows.

Early Access

Advisors will evaluate prototypes first and contribute to the evidence base we build toward clearance.
