Cost Effective:The cost of a single night for a sleep test in a lab can range between $1,500 and $4,000. Using the Zyppah Home Sleep Test, your cost is only $450 for 3 nights or ($350 for 2 nights), plus $27.95 for shipping and handling. That's one third of the cost of an attended sleep study in a lab.
Convenient:There's nothing better than sleeping in your own bed. With the Zyppah's 3 Night Home Sleep Test, you don't have to drive to a center, miss work, or hassle with your insurance company to see if this is covered. You don't have to feel uncomfortable while complete strangers watch you sleep/snore. The testing unit is delivered to your home via FedEX with everything included. Once you finish the third night, you send it back and get your results in a few days.
Comfortable:The Zyppah Home Sleep Test unit is very comfortable. It feels like you're wearing a baseball cap or visor. You are not connected to any wires or probes and you can sleep normally. When taking a test at a lab or sleep center, you are connected to several wires and are asked to try to avoid rolling over to prevent disconnecting the sensors. If you have to go to the bathroom in the middle of the night you have to detach and reattach all of the wires. The Zyppah testing equipment stays on head regardless of sleeping position and there are no wires to adjust if you get up in the night.
Comprehensive:Put simply, three nights of testing are better than one. As a patient, the goal is to get the most information about the status of your health. When you order the 3 night sleep test, you get a broader picture of your sleeping profile. This information is invaluable because you are getting 3 times the data to help arrive at a diagnosis of the issues that may affect your sleep behavior.
The 3-Night Home Sleep Test by Zyppah uses the Watermark ARES unit. It captures details in 0.10% (one tenth of a percent) increments rather than the typical 1%, which allows identification of small but important changes in saturation. The unit captures eight different items during the home sleep test.
Apnea/Hypopnea Index (AHI) – The test determines AHI by adding the number of apneas and hypopneas per hour, where there is a 4% oxygen desaturation.
Airflow (nasal pressure) – The test determines changes in air pressure that are measured with a pressure transducer connected to the nasal opening via a nasal cannula. Decreases and increases in flow of 50% or more are automatically identified and marked as hypopneas and cessations of airflow for at least 10 seconds are marked as apneas.
Pulse Rate – The test uses reflectance pulse oximetry to measure pulse rate. Limited smoothing of pulse rate signal increases capability of the internal software to recognize brief changes in pulse rate (e.g., Brady-tachycardias). These changes in pulse rate are recognized markers of arousal.
Snoring – The test records snoring levels with a calibrated acoustic microphone so that the level of loudness can be precisely quantified. Changes in snoring patterns and crescendo snoring are automatically recognized and used as markers of respiratory-related arousals.
Head Position/Movement – The test identifies head position and indicates the position of the pharynx and is used to determine the positionality of obstructive events. Understanding the influence of position on the severity of the OSA is useful in making treatment decisions. Head movement is measured using accelerometers similar to those used for actigraphy. Head movement is a unique signal identified by ARES as a marker of respiratory related arousal.
Sleep/Wake – The test measures sleep behaviorally by combining the detection of subtle movements through actigraphy, with variability of the airflow signal and recognition of snoring.
REM/NREM – The test distinguishes REM from NREM using EEG, EOG and EMG signals derived from two electrodes placed at FP1 and FP2 on the forehead.
Respiratory Disturbance Index (RDI) – The test measures RDI by adding the number of apneas and hypopneas per hour, where the hypopneas require a 1% oxygen desaturation/resaturation and at least one behavioral arousal indicator.
