From level-one trauma centers to small-animal veterinary clinics, Bair Hugger systems serve teams who can’t compromise on patient temperature management.
Maintaining Normothermia in Long Cases
Surgical teams running multi-hour orthopedic and abdominal procedures rely on the Bair Hugger 775 paired with upper or underbody blankets to keep core temperature stable from incision to closure. The combination of a dedicated warming unit and disposable blanket is the workflow most ORs are built around.
Pre-Warming with Bair Hugger Gowns
Pre-op nurses use the Bair Hugger warming gown to start pre-warming the moment the patient arrives — reducing the temperature drop that often follows anesthesia induction. In recovery, the same gown becomes a PACU comfort tool, helping patients warm faster after surgery.
Forced-Air Warming for Animal Patients
Veterinary surgical teams use Bair Hugger veterinary blankets and the cage adapter to deliver warming through recovery cages — a practical answer to the thermoregulation challenges of small and large animal patients under anesthesia.

Bair Hugger Lives Where the Work Happens
Across surgical suites, recovery rooms, ambulatory centers, and veterinary clinics, Bair Hugger forced-air warming has become a quiet constant — the unit humming next to the table, the disposable blanket draped over the patient, the hose connected and routed without a second thought.
Biomeds know the model numbers by heart: the 505, the 750, the 775, the 875. OR techs know which blanket goes with which case. Veterinary technicians know the cage adapter setup by memory. Bair Hugger has earned that familiarity by doing one thing reliably for more than three decades — moving warm, filtered air to the patients who need it.

Things People Ask Us About Bair Hugger
Straight answers to the most common questions about Bair Hugger warming units, blankets, accessories, and veterinary applications.
The Bair Hugger system is a forced-air patient warming system originally developed by 3M. It pairs a Bair Hugger warming unit (such as the 775 or 875) with a disposable Bair Hugger blanket or gown. The unit pulls in room air, filters and warms it, then blows it through a hose into the inflatable blanket that contacts the patient — keeping body temperature stable before, during, and after surgery.
The Bair Hugger 775 is the standard high-performance warming unit found in most operating rooms today. The Bair Hugger 875 is designed for pre-op and PACU environments where awake patients are being warmed. Older units like the Bair Hugger 505, 750, and earlier 700-series models are still in service in many facilities and remain supported through replacement accessories like filters and hoses.
It’s about where surgical access is needed. A Bair Hugger upper body blanket warms the torso and leaves the lower body accessible. A Bair Hugger lower body blanket does the opposite. The Bair Hugger underbody blanket sits beneath the patient, warming from below while leaving the entire anterior surface available for the surgical team. Choice depends on procedure type and positioning.
Bair Hugger 775 filter replacement intervals follow the schedule outlined in the unit’s service manual — typically based on hours of use or a calendar interval, whichever comes first. Keeping fresh filters in your Bair Hugger 775 protects warming performance and helps your biomed team pass routine PMs. We stock replacement filters and accessories for the full 700-series.
Yes. The Bair Hugger veterinary system, combined with veterinary-specific blankets and the Bair Hugger cage adapter, is widely used in small and large animal surgical practice. The cage adapter in particular lets clinics deliver controlled forced-air warming directly into a recovery cage, which has become a go-to tool for post-anesthetic thermoregulation in veterinary patients.
Bair Hugger is fundamentally a clinical forced-air warming system designed for hospital, ambulatory surgical, and veterinary environments. While some buyers do source older Bair Hugger 875 units secondhand, the system is intended for trained clinical use with appropriate disposable blankets and gowns. Always follow the operator manual for the specific warming unit model.
