No
The description focuses on basic microprocessor control for setting parameters and maintaining constant motor speed, with no mention of learning, adaptation, or complex pattern recognition characteristic of AI/ML.
Yes
The device is indicated for the treatment of Obstructive Sleep Apnea, which is a medical condition, making it a therapeutic device.
No
The intended use of the GoodKnight 418 is to provide Continuous Positive Airway Pressure (CPAP) for the treatment of Obstructive Sleep Apnea, indicating a therapeutic rather than diagnostic purpose. It is stated to "treat obstructive sleep apnea," not diagnose it.
No
The device description clearly outlines hardware components such as a blower motor, power supply, and microprocessor, and describes how these components function together to deliver CPAP. While software is mentioned as being used to set parameters, it is integral to the operation of the physical device and not a standalone software product.
Based on the provided text, the GoodKnight 418 is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use is to provide Continuous Positive Airway Pressure (CPAP) for the treatment of Obstructive Sleep Apnea in spontaneously breathing patients. This is a therapeutic intervention, not a diagnostic test performed on samples taken from the body.
- Device Description: The description details a mechanical device that delivers pressurized air. It does not mention any components or processes related to analyzing biological samples (blood, urine, tissue, etc.).
- Lack of IVD Characteristics: The text does not mention any of the typical characteristics of an IVD, such as reagents, calibrators, controls, or the analysis of biological specimens.
Therefore, the GoodKnight 418 is a therapeutic medical device, not an IVD.

Device Description
The GoodKnight 418 CPAP System is a device used to provide Continuous Positive Airway Pressure between 4 and 18 cmH2O.
The device is powered by AC Mains from 96 to 138 VAC, 60 Hz. The blower motor nominal voltage is 160 VDC, which is obtained by rectifying and filtering the nominal mains power voltage of 120 VAC. The device is double-insulated so that grounding is not required.
The device is set up for use by the homecare dealer using the Set-up Instructions provided with the device. It is operated by following directions in the Patient Guide. Pocket Cards are also provided for both the patient and the homecare dealer as a convenience.
The pressure is set to the prescription with the use of a patient circuit, with the pressure being measured at the patient end of the circuit. By using this method, losses associated with the patient circuit are compensated for and, thus, the device does not require a pressure transducer.
The device uses a microprocessor to set the various control parameters, turn features on and off and view the set parameters.
Pressure regulation is accomplished by maintaining a constant motor speed. This is done by the microprocessor counting the motor RPM pulses and then changing the motor speed voltage supplied to the motor drive circuit as required to maintain constant speed.
The GoodKnight 418 has the following functions:
- On/Off
- Calibration
- Set Prescription Pressure
- Check Prescription Pressure
- Enable/Disable Ramp Feature
- Set Ramp Starting Pressure
- Start Ramp Feature
- Enable/Disable Altitude Compensation Feature
- Compensating for Changes in Altitude
The accessories, i.e., the patient tubing, patient masks and headgear are the same ones used with the GoodKnight 318.
The device is not for use in life-supporting or life-sustaining situations.
Neither the device nor its accessories are sterile.
The device itself and the air filter are for multiple use. The other accessories, i.e., the patient circuit and nasal masks are for single patient use.
The device is for prescription use and contains appropriate labeling.
The device is for use in a homecare environment.
The device does not contain a drug or biological product as a component. However, it can be used to provide the patient with supplemental oxygen.
The device is not part of a kit.
Software is used to set the various device parameters such as the prescription pressure and the ramp starting pressure, and to enable/disable the ramp and altitude compensation features.
The device is electrically operated.
The device complies with certain voluntary standards, specifically the draft ARDB Reviewer Guidance for Premarket Notification Submissions (Nov 1993) and CAN/CSA C22.2 No. 601.1-M90 (1994).

5.0 Intended Use
The intended use of the GoodKnight 418 is to provide Continuous Positive Airway Pressure (CPAP) between 4 and 18 cmH,O to spontaneously breathing patients over 30 kg for the treatment of Obstructive Sleep Apnea in a homecare environment.
6.0 Comparison of Technological Characteristics
The voltage range for the GoodKnight 418 is 120VAC nominal. For the GoodKnight 318 the range is 110-240 VAC nominal. The 418 has a motor voltage of 160 VDC instead of 24 VDC as does the 318. The 418 is double-insulated whereas the 318 requires grounding.
The GoodKnight 418 uses a microprocessor to set the various controls whereas the GoodKnight 318 uses mechanical means such as a potentiometer to set prescription pressure and DIP switches to set the ramp parameters. The GoodKnight 418 has a fixed ramp duration of 15 minutes whereas the GoodKnight 318 has a ramp duration of 5, 10 or 20 minutes depending on the DIP switch settings. Also, the 418 has a variable ramp starting pressure, from 3.9 cmHJO up to the prescription pressure, whereas the 318 has a fixed ramp starting pressure. For both devices, these parameters are within the same range and are thus are not clinically significant.
The GoodKnight 418 has an Altitude Compensation feature whereas the GoodKnight 318 does not. To read the control settings on the GoodKnight 418 CPAP System, the user presses various buttons and counts the number of times the Indicator Lamp flashes, whereas with the GoodKnight 318 the user reads the pressure gage and looks at the DIP switch settings.
The lowest pressure available with the GoodKnight 418 is 1.0 cmH2O higher than with the GoodKnight 318.
The GoodKnight 418 does not have a compliance meter whereas the GoodKnight 318 has one as optional equipment.
The GoodKnight 418 uses a microprocessor to set and read the control settings whereas the GoodKnight 318 uses analog technology to perform these functions.
