Yes
The device is intended to treat patient body-core cooling and provide topical heating, which are therapeutic actions.
No
The device is described as an infrared lamp that provides topical heating to alleviate patient body-core cooling. It does not perform any diagnostic function.
No
The device description clearly outlines physical hardware components including a heater assembly, controller unit, mounting pole, base, and accessories like temperature sensor probes. While it includes electronics and control software, it is fundamentally a hardware device with integrated software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- Device Function: The Fisher & Paykel Healthcare PW820 Surgical Patient Warmer is an external device that uses infrared energy to provide topical heating to a patient's skin. It does not analyze any biological samples.
- Intended Use: The intended use is to alleviate patient body-core cooling and provide external thermal support. This is a therapeutic/supportive function, not a diagnostic one.
The device description and intended use clearly indicate that it is a medical device used for patient warming, not for performing diagnostic tests on biological samples.

Intended Use / Indications for Use
The Fisher & Paykel Healthcare PW820 device is an Infra-red Lamp, as per 21 CFR §890.5500. It emits energy at infra-red frequencies to provide topical heating, and is used to provide thermal support for anesthetized patients (who are susceptible to undesirable heat loss) undergoing surgical treatment. Additionally, the PW820 may also be used to provide topical heating in other clinical situations where unobstructive external thermal support for patients is required (for example, post-operative recovery, hypothermia recovery).
The Fisher & Paykel Healthcare PW820 Surgical Patient Warmer is an Infra-red lamp. It emits energy at infra-red frequencies to provide topical heating.

Device Description
The PW820 Surgical Patient Warmer consists of a heater assembly and controller unit, with mounting pole and base sections. The heater assembly includes a single rod infrared heating element housed inside a parabolic reflector. Two spotlights (designed to set the distance of the heater from the patient) are mounted at the back of the heater assembly. The heater assembly can be swung either side of the warmer, away from the patient, or rotated through ± 90° along the patient axis. A metal grill on the underside of the heater prevents contact with the heating element.
The controller unit supports the heater assembly, and contains the device electronics, control panel and labels. The front panel contains the control buttons, temperature display, main power switch and temperature sensor socket. Controls include temperature selection and positioning spotlight operation. LED displays include indicators for set temperature, alarms, positioning spotlights, heater power, and a 3 digit skin temperature display. The main label is located on the controller rear panel. and the power socket is mounted in the underside of the controller.
A single pole mounting system supports the controller unit, with two sections of stainless steel tubing providing height adjustment. The lower pole section is mounted into a stabilizer weight attached to a five-arm base unit, with castors which include foot-operated brake levers.
Accessories for the PW820 include 'Reusable' and 'Single Use' skin temperature sensor probes, cord tidy, I.V. pole and bag hook.
When switched on, with the desired temperature selected and sensor positioned correctly on the patient, the PW820 provides stable control of skin temperature by automatically adjusting the heater power to compensate for varying metabolic and environmental conditions. Audible and visual alarms alert the user to high/low temperature situations, faults and power failure. Independent safety features are included to control maximum output and avoid thermal injury to the patient.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
A randomized, controlled trial compared the efficacy of the PW820 with that of a forced air warming blanket in providing intra-operative warming for patients undergoing laparoscopic cholecystectomy surgery. The results showed that the PW820 was at least as effective as the warming blanket in maintaining patient temperature during both surgery and the recovery period.
