The Alice NightOne is a home sleep apnea test (HSAT) device, designed for convenient sleep assessment.
It allows patients to undergo diagnostic testing within the comfort of their own homes, simplifying the process.
What is the Alice NightOne?
This device, manufactured by Philips Respironics, is a compact and user-friendly system for detecting sleep apnea.
It records key physiological signals during sleep, providing valuable data for medical professionals.
Purpose of the Home Sleep Apnea Test (HSAT)
The primary goal of the HSAT is to identify the presence and severity of obstructive sleep apnea (OSA).
Early detection and diagnosis are crucial for managing this common, yet often undiagnosed, condition.
The Alice NightOne is a comprehensive home sleep apnea testing (HSAT) device created by Philips Respironics. It’s a streamlined system designed for single-night use, offering a comfortable and convenient alternative to traditional lab-based sleep studies.
The device utilizes a simplified setup, including an effort belt, nasal cannula, and pulse oximeter, to monitor breathing patterns and oxygen levels during sleep. Its intuitive design, as highlighted in quick start guides, aims to ensure accurate data collection for effective diagnosis.
The HSAT, utilizing the Alice NightOne, aims to diagnose obstructive sleep apnea (OSA), a condition where breathing repeatedly stops and starts during sleep. This test conveniently assesses a patient’s respiratory effort, oxygen saturation, and heart rate overnight.
Identifying OSA is vital, as it’s linked to various health risks, including cardiovascular problems and daytime fatigue. The HSAT provides crucial data for healthcare professionals to determine appropriate treatment plans and improve patient well-being.

Unboxing and Device Overview
The Alice NightOne kit contains essential components for a successful sleep study. Familiarizing yourself with these items and the device’s features is a crucial first step.
Components Included in the Kit
Expect an Alice NightOne device, effort belt, nasal cannula, pulse oximeter, and adhesive sensors. A quick start guide assists with setup and operation.
Understanding the Device Icons

Preparing for Your Sleep Study
Prior to your sleep study, ensure optimal sensor adhesion and data quality. Wearing a comfortable t-shirt or loose-fitting top is recommended for proper belt placement.
Wearing a T-Shirt or Loose Fitting Top
A t-shirt facilitates secure placement of the effort belt around your chest, ensuring accurate respiratory effort measurements throughout the night.
Ensuring Sensors are Dry
It’s vital that all sensor application sites are clean and completely dry before applying the sensors. Moisture can interfere with signal transmission.
For optimal results with the Alice NightOne HSAT, wearing a t-shirt or loose-fitting top during your sleep study is highly recommended. This clothing choice provides a comfortable and secure base for correctly positioning the effort belt.
The effort belt, crucial for measuring your breathing effort, needs to be snug but not constricting. A t-shirt prevents direct skin contact, enhancing comfort and ensuring the belt remains in the correct position throughout the night, leading to more accurate data collection.
Maintaining dry sensors is absolutely critical for accurate data collection with the Alice NightOne. Moisture can interfere with the sensors’ ability to properly record your physiological signals during sleep. Before applying any sensor – the effort belt, nasal cannula, or pulse oximeter – ensure your skin is clean and completely dry.
Avoid applying lotions or oils to the areas where the sensors will be placed. Even slight dampness can compromise the test results, potentially leading to an inaccurate diagnosis.

Attaching the Sensors
Proper sensor placement is vital for a successful sleep study with the Alice NightOne. This involves carefully applying the effort belt, nasal cannula, and pulse oximeter according to the guide.
Applying the Effort Belt
Place the effort belt snugly around your chest, ensuring it’s positioned correctly to measure breathing effort. Wear a t-shirt or loose-fitting top.
Connecting the Nasal Cannula
Gently insert the nasal cannula into your nostrils, ensuring a comfortable and secure fit for airflow monitoring.
Positioning the Pulse Oximeter
Attach the pulse oximeter to your finger, making sure it’s properly aligned to accurately measure your oxygen saturation levels.
The effort belt is a crucial component, measuring your chest movement during breathing. Place it securely around your chest, directly over your ribs, ensuring a snug but comfortable fit.
It’s recommended to wear a t-shirt or loose-fitting top underneath the belt to prevent skin irritation and ensure accurate readings.
The belt should not be too tight, restricting your breathing, nor too loose, allowing for movement that compromises data collection. Refer to the picture guide included in your kit for visual assistance with correct positioning. Proper placement is key for reliable results.
The nasal cannula gently delivers air to monitor your breathing patterns during sleep. Carefully insert the prongs of the cannula into your nostrils, ensuring a comfortable and secure fit. Connect the cannula’s tubing to the designated port on the Alice NightOne device.
Ensure the connection is firm to prevent dislodgement during the night. Avoid excessive force when inserting the prongs. A proper seal is vital for accurate airflow measurements, contributing to a reliable sleep study result.
The pulse oximeter measures your blood oxygen saturation and pulse rate throughout the night. Securely attach the device to your index finger, ensuring it fits snugly but isn’t overly tight. Connect the pulse oximeter cable to the corresponding port on the Alice NightOne unit.
Verify the sensor is properly aligned for accurate readings. Movement during sleep can sometimes disrupt the signal, so a secure fit is essential for reliable data collection during your sleep study.
Starting the Device
To begin your sleep study, press the power button on the Alice NightOne. Confirm all sensor connections are established, indicated by solid green lights on the device.
Powering On the Alice NightOne
Pressing the power button initiates the data recording process. Ensure the device is fully powered on before retiring for the night.
Verifying Sensor Connections (Green Lights)
Green lights signify proper sensor function. If lights are absent or red, re-check connections before starting your sleep study.
Initiating the device is straightforward. Locate the power button on the top of the Alice NightOne unit. A single press activates the system, beginning the data collection process for your home sleep apnea test. The device will briefly display a startup screen, confirming it’s powering on correctly.
Ensure the device remains stationary throughout the night. Avoid pressing any other buttons unless specifically instructed to do so during troubleshooting. A fully powered-on device is essential for accurate data recording and a successful sleep study.
Confirming proper sensor attachment is vital. After connecting all sensors – the effort belt, nasal cannula, and pulse oximeter – observe the indicator lights on the Alice NightOne. Each sensor has a corresponding icon on the device’s top panel.
A solid green light beneath each icon signifies a secure and functioning connection. If any light is red or flashing, re-check the sensor attachment. Correct connections ensure accurate data capture during your sleep study.
