The description details a radar-based system that measures chest displacement and converts it to a respiratory rate using software. There is no mention of AI or ML algorithms being used in this process.
No
The device is intended for a one-time measurement of respiratory rate as part of a vital signs assessment and is not described as providing any therapeutic benefit or intervention.
Yes
Explanation: The device is intended for a one-time measurement of respiratory rate as part of a vital signs assessment, which is a common diagnostic function to assess a patient's health status.
No
The device description explicitly states it uses a "reusable sensor" and a "hardware module" with a "low-power radar" to sense chest displacement. While software is used for processing and display, the core functionality relies on dedicated hardware.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The Kai Sensors Non-Contact Respiratory Rate Spot Check Model 100 measures respiratory rate by sensing chest displacement using radar technology. It does not analyze any biological samples taken from the patient.
- Intended Use: The intended use is for a one-time measurement of respiratory rate as part of a vital signs assessment, which is a direct measurement of a physiological parameter, not an analysis of a biological sample.
Therefore, the device falls under the category of a medical device that measures a physiological parameter directly from the patient, rather than an in vitro diagnostic device.

Device Description
The Kai Sensors Non-Contact Respiratory Rate Spot Check Model 100 ("Kai RSpot 100") is a reusable sensor for measuring respiratory rate during vital sign spot checks. The Kai RSpot 100 uses a low-power radar to sense chest displacement in order to obtain a respiratory rate. When the hardware module is operating and facing a patient, the Doppler radar transmits a low-power radio-frequency signal and receives the signal after it has reflected off the patient's torso. The receiver detects a phase shift on the signal due to chest displacement and converts this phase shift into a voltage that is digitized and sent to the computer portable computer via USB. The portable computer runs the Kai RSpot 100 software, which determines a respiratory rate from the chest motion (respiratory effort) signal and provides the display, user interface, and power source for the device. The portable computer can operate on battery power or on wall power through outlets when used with the supplied power cord.

The device is indicated for hospital or clinical use in adult patients. The device is intended to be operated by clinicians and medically qualified personnel.

Technological Characteristics
The Kai Sensors Non-Contact Respiratory Rate Spot Check Model 100 ("Kai RSpot 100") is a reusable sensor for measuring respiratory rate during vital sign spot checks. The Kai RSpot 100 uses a low-power radar to sense chest displacement in order to obtain a respiratory rate. When the hardware module is operating and facing a patient, the Doppler radar transmits a low-power radio-frequency signal and receives the signal after it has reflected off the patient's torso. The receiver detects a phase shift on the signal due to chest displacement and converts this phase shift into a voltage that is digitized and sent to the computer portable computer via USB. The portable computer runs the Kai RSpot 100 software, which determines a respiratory rate from the chest motion (respiratory effort) signal and provides the display, user interface, and power source for the device. The portable computer can operate on battery power or on wall power through outlets when used with the supplied power cord.
Performance Data
The bench and clinical performance data demonstrates that the Kai RSpot 100 is as safe and effective as its predicate devices. The bench testing of this device demonstrates that the Kai RSpot 100 operates within its specifications, including accuracy over the range of measured respiratory rates. Clinical testing of the device demonstrated its ability to generate respiratory rate information of sufficient accuracy for its intended use.

Because the Kai RSpot 100 does not contact the patient, there is no risk of inadvertent exposure to electric current, and there are no patient-contacting materials that could cause allergic reactions or skin sensitivity. The radio signals emitted by the Kai RSpot100 are at a power well below that emitted by many consumer wireless devices and many medical devices.
Substantial Equivalence
The Kai RSpot100 and its predicate devices, which include the Welch Allyn Propaq 200series monitors (K012451) and the Embletta Gold system with Universal XactTrace belts and Somnologica software (K043132, K073682, and K971813), have the same intended use and similar indications, technological characteristics and principles of operation.
The Kai RSpot 100, the Welch Allyn Propaq 200-series (K012451), and the Embla Embletta system with XactTrace belts and Somnologica software (K043132, K073682, and K971813) all provide a respiratory rate based on a respiratory effort measurement. The minor technological differences between the Kai RSpot 100 and its predicate devices raise no new issues of safety or effectiveness. The bench and clinical performance data demonstrate that the Kai RSpot 100 is as safe and effective as the Welch Allyn Propag 200-series monitors (K012451) and the Embla Embletta Gold system with Medcare Flaga Universal XactTrace belts and Ferguson Medical Somnologica software (as part of Embla system) (K043132, K073682, and K971813). Thus, the Kai RSpot 100 is substantially equivalent to its predicate devices.
