Tips for Buying Polysomnography

1. Before purchasing computerized polysomnography analyzers, facilities should carefully evaluate their clinical needs to ensure acquisition of proper equipment.

2. Buyers should consider operating and installation costs, including electrodes and adhesive gel, installation of network cables and interface devices, hardware and software maintenance, storage devices, and media.

3. These devices enable the study of a variety of physiologic activities simultaneously and are therefore useful diagnostic tools.

4. The standard polysomnography protocol should include: electroencephalography, electrooculography, electrocardiography, submental and limb electromyography, measurements of airflow, respiration, and blood oxygenation, and a collection of audiovisual information on patient behavior during sleep. The standard for each room should be one polysomnograph with at least 10 channels capable of continuous monitoring.

5. Montages should be user programmable or selectable, and the unit should have trending and full disclosure.

6. There are different operating systems, database management, networking, input and output, and data storage options. Data retrieval and storage options should be decided by clinicians.

7. Some models can only be used within the sleep clinic or laboratory, while others allow monitoring within the patient's home.

8. A quiet, appropriately furnished room free of interference from light and noise is necessary, in addition to the purchase of equipment. For the patient's comfort, an adjoining bathroom with a shower may be helpful in preparations for sleep. 

9. Computerized polysomnography analyzers hold some advantages regarding costs, including a reduction in the amount of time needed to manually score polysomnograph readings, a decrease in storage requirements and the need for storage space, and eliminating the need for supplies such as paper, ink, and pens. 10. Some alternative means of monitoring sleep disorders exist, such as apnea monitors.
