Brand new in the box never even opened! Icon+ ICON Auto CPAP Machine with Built-In Heated Humidifier and ThermoSmart Heated Hose is an improvement over Fisher & Paykels SleepStyle 200 Auto Series of machines. The ICON Auto incorporates both SensAwake pressure relief and and ThermoSmart humidification in a streamlined body. The built-in heated humidifier and heated hose delivers condensation-free humidification at the touch of a button. The ICON Auto is ideal for home or travel and comes with an alarm clock and music playing ability. Features Auto Algorithm SensAwake Pressure Relief Technology ThermoSmart Heated Hose SmartDial - Sleep Data & Functions Alarm Clock & AlarmTunes Ramp Feature Auto Altitude Adjustment Travel Size Auto Algorithm The ICON Auto is designed to deliver on-demand pressure. As sleeping habits can vary daily, the ICON Auto uses a flow-based auto-adjusting algorithm to continually check for flow limitations, apneas, and hypopneas on a breath-by-breath basis. When an event occurs, the Auto algorithm begins to increase pressure until the obstruction clears or the maximum pressure setting is reached. Fisher and Paykel has a benchmark comparison of the ICON Auto and other auto-adjusting CPAP machines on the market. Auto-Adjusting CPAP Evaluation on the Bench SensAwake Technology SensAwake is a pressure relief technology that addresses user intolerance for Continuous Positive Airway Pressure therapy. Comfort is critical during an awakened state, particularly for new users who have difficulty returning back to sleep when CPAP pressures are high. SensAwake monitors CPAP airflow and reduces pressure levels when respiration becomes irregular. Irregular breathing is a general marker that a user is transitioning from a sleep state to an awakened state. This personalized treatment prevents users from awakening and ultimately improves therapy effectiveness. Irregular Respiration as a Marker of Wakefulness Please note: SensAwake will only be available for the Icon Auto in CPAP mode for versions lower than 2.0. If your Icon Auto is a version 2.0 or higher the SensAwake will be available in APAP or CPAP mode. To determine which version you have, you will need to be in the Clinical Menu of the machine, select the "wrench" icon and move the dial one over to the right. The version of your Icon Auto will then appear. ThermoSmart Humidification & Heated Hose Under normal circumstances the air you breathe is naturally heated as it travels through your nasal passages. CPAP therapy works against this natural humidification. CPAP airflow drys the nasal passages and can lead to congestion and mouth breathing. Typical heated CPAP humidification helps re-saturate therapy air, but effectiveness is restricted by ambient temperatures. As the room cools, most humidifiers cannot keep relative humidity levels at the mask, usually resulting in condensation forming in the CPAP hose. ThermoSmart Technology delivers custom levels of high humidity that are maintained throughout the night, regardless of ambient temperature. The ICON uses sensors that track ambient room temperature to reduce condensation. To maximize the ICON's capabilities, Fisher and Paykel offer an optional heated breathing tube that works in conjunction with ThermoSmart Technology. This heated CPAP hose contains copper coils embedded in tubing and is 76.5 inches in length. These coils conduct heat and can provide a constant temperature throughout the hose. The optional ThermoSmart breathing tube virtually eliminates rain-out and condensation in a CPAP hose. Impact of ThermoSmart and Heated Tubing Comparative Study of Humidification Effectiveness As an added benefit, ThermoSmart can also help lower overall therapy pressures. As higher levels of humidity start to relieve swelling within your nasal passages, resistance to therapy pressures can decrease and lower levels of therapy may become effective. Effects of Humidification on Titration Pressures Alarm Clock & AlarmTunes The compact design and clock functionality makes the Fisher and Paykel ICON an ideal substitute for the bedside night stand. The ICON incorporates a single SmartDial that uses a "Press-Turn-Press" principle. Turn the dial to access efficacy data from the display or set the built-in alarm clock and music playing ability with the AlarmTunes function.
