The document describes a standard patient warming system using forced air and a blanket, with no mention of AI or ML in the intended use, device description, or performance studies.
Yes
The device is described as providing "patient therapy by the means of warmed air" and is used to "raise a patient's temperature and/or maintain a desired patient temperature," which indicates a therapeutic purpose.
No
The device is a patient warming system intended to prevent hypothermia and reduce cold discomfort, which are therapeutic functions, not diagnostic ones.
No
The device description clearly states it is a "patient temperature management device which provides forced air warmed by the controller to a blanket" and mentions a "connecting flexible hose." This indicates the device includes significant hardware components (controller, hose, blanket) beyond just software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to prevent hypothermia and reduce cold discomfort by warming the patient's body. This is a therapeutic intervention applied directly to the patient.
- Device Description: The device description details a system that provides warmed air to a blanket placed on or under the patient. This is a physical method of heat transfer to the body.
- Lack of IVD Characteristics: There is no mention of analyzing samples from the human body (blood, urine, tissue, etc.) or providing information about a physiological state, disease, or condition based on such analysis.
IVD devices are used to perform tests on samples taken from the body to provide diagnostic information. This device directly interacts with the body to provide therapy.

Intended Use / Indications for Use
The WarmAir® 135 patient warming system is intended to prevent hypothermia and/or reduce cold discomfort before, during, and after surgical procedures. The thermal regulating system is used to raise a patient's temperature and/or maintain a desired patient temperature through convective heat transfer from the controller to a warm-air-heated blanket. The single-patient use blankets transfer the thermal energy to adult, pediatric or neonate patients to obtain/maintain normal body temperature. It is intended for use by appropriately trained healthcare professionals in clinical environments.

DEVICE DESCRIPTION
The WarmAir 135 Hyperthermia System is a patient temperature management device which provides forced air warmed by the controller to a blanket that is placed over or under adult, pediatric or neonatal patients in order to warm them. The heated air is blown through connecting flexible hose to a disposable blanket to provide patient therapy by the means of warmed air.
.
The system can be used in long-term care facilities, surgical facilities, hospitals including the Post-anesthesia Care Unit (PACU), Intensive Care Unit (ICU), Surgical Intensive Care Unit (SICU), Emergency Room (ER), Operating Room (OR), recovery room, medical and surgical floors, emergency department, or any other department or hospital facility requiring patient temperature management.
DESCRIPTION OF THE DEVICE CHANGES
The predicate WarmAir System, Model 133 used a thermistor for the primary temperature safety and a bulb capillary type or thermostat for the secondary temperature safety. The new Model 135 uses a thermistor for the primary temperature safety and a snap disc thermostat for the secondary temperature safety. The specifications for the primary and secondary safety shut-down set points have changed from the prior model.
INTENDED USE
The WarmAir 135 patient warming system is intended to prevent hypothermia and/or reduce cold discomfort before, during, and after surgical procedures. The thermal regulating system is used to raise a patient's temperature and/or maintain a desired patient temperature through convective heat transfer from the controller to a warm-airheated blanket. The single-patient use blankets transfer the thermal energy to adult, pediatric, or neonate patients to obtain/maintain normal body temperature. It is intended for use by appropriately trained healthcare professionals in clinical environments.
BENCH TESTS PERFORMED IN DETERMINATION OF SUBSTANTIAL EQUIVALENCE
Bench testing was performed in order to validate the design according to the company's specified design requirements, and to demonstrate the new systems are substantially equivalent to the predicate devices.
The following bench tests were performed:
- Temperature Performance Testing .
- System Safety Limit Testing .
- Transportation Testing .
- Blanket Structural Integrity Testing .
In addition, the new systems meet the applicable requirements of the following standards:

- IEC 60601-1-2, Medical Electrical Equipment Part 1-2: General Requirements . for Safety - Collateral Standard: Electromagnetic Compatibility -- Requirements and Tests.
All necessary testing has been performed for the WarmAir 135 Hyperthermia system to assure substantial equivalence to the predicate devices.
SUBSTANTIAL EQUIVALENCE
The modified devices have the same intended use as the predicates and similar technological characteristics that do not raise new types of questions of safety and effectiveness and are therefore substantially equivalent to the predicate devices.
