DeVilbiss CPAP Model DV51 Firmware History

V0.13 21/08/2009

• The Adherence Score was updated to better accommodate breaks from use during the night.  Please note that this change only applies to data collected after the update.

• Added a low backlight disable feature (setting in Enable Menu).  When the setting is disabled the keypad and LCD backlight will completely turn off when the blower is OFF or after one minute of inactivity.

• Added a feature to allow the user to access the SmartCode and Adherence Score data with the blower OFF.  Pressing the LEFT or RIGHT arrow keys with the blower OFF gives access to these values.

• Fixed an issue with Clinical Menu entry.  On prior versions of firmware, the language could have been inadvertently changed during the prescription unlock key sequence.

• Added a new Auto-ON/OFF lockout setting.  This feature allows the health care provider to lock the Auto-ON and Auto-OFF settings from being changed by the patient.

• When Auto-OFF is enabled, Auto-ON is also enabled and cannot be changed.  This assures that if a unit shuts off (Auto-OFF) due to a mask-off condition, that it will also automatically turn on when the mask is back in place.  Auto-ON can only be disabled if Auto-OFF is first disabled.

V0.12 15/01/2009

• Added an enhanced “SmartCode” feature that is intended to give access to compliance and therapy management information using encrypted codes.  The “SmartCode” consists of two separate codes displayed in the patient menu.  The two codes include “Last 1/7/30/90 Days” and “Cumulative Usage”.  In addition to the codes, a “Low Use Threshold” setting was added to the clinical menu.

• Added an "Adherence Score" feature to the unit.  Adherence score is the maximum percentage of continuous usage >= "Usage Threshold" over a consecutive 30 day period anytime during the last 90 days of usage.  Adherence Score is displayed in the patient menu and is also included in the SmartCode.

• The "Delay ON" notification message now only occurs if the main view screen is displayed.

• The Auto-ON feature no longer increases the keypad and LCD backlight intensity.

• Disabled Auto-OFF while SmartCodes are being displayed.

• Corrected a DV5HH heater on/off control issue.

• Implemented various translation corrections based on customer feedback.

• Made changes to improve blower control performance.

• The AutoAdjust delay feature was changed to add a delay pressure setting. The AutoAdjust delay now works like the CPAP delay (pressure starts at delay pressure setting and ramps to the lower pressure limit). The delay button must be pressed to start the delay (no longer starts when the blower is turned on).

• Implemented various translation corrections based on customer feedback.

• Moved the hour meter parameter from the patient menu to the clinical menu.

• Added the serial number parameter to the blower off menu.

• Made minor changes to SmartCode session detection to improve performance.  This change eliminates false logging of "extra sessions" during a 24 hour usage day.

• The "Delay ON" notification message now only occurs if the main view screen is displayed.

V0.17 06/11/2008

• Added an enhanced “SmartCode” feature that is intended to give access to compliance and therapy management information using encrypted codes.  The “SmartCode” consists of five separate codes displayed in the patient menu.  The five codes include “Last Day”, “Last 7 Days”, “Last 30 Days”, “Last 90 Days", and “Cumulative Usage”.  In addition to the codes, a “Low Use Threshold” setting was added to the clinical menu.
