Powering On and Off
To power on the CAIRE FreeStyle Comfort, press and hold the rectangular power button located on the device’s control panel for approximately two seconds. You will hear an audible tone and the LCD screen will illuminate, indicating the unit is starting up and performing its self-test. Allow the device to complete the self-test before initiating oxygen therapy.
To power off the concentrator, again press and hold the same rectangular power button for two seconds. The screen will display a shutdown sequence, and another audible tone will confirm the device is powering down. Ensure the unit is completely off before disconnecting the battery or attempting any maintenance.
Important Note: Avoid repeatedly pressing the power button rapidly, as this may not initiate the power-on or power-off sequence correctly. Always use a firm, sustained press for two seconds.
Adjusting Pulse Settings (5 Levels)
The CAIRE FreeStyle Comfort offers five adjustable pulse settings, allowing for personalized oxygen delivery based on individual needs and physician recommendations. To adjust the pulse setting, briefly press the circular button with the plus (+) or minus (-) symbol. Each press will cycle through the available levels, displayed numerically on the LCD screen – from 1 (lowest) to 5 (highest).
Level 1 is suitable for minimal exertion, while Levels 2-4 cater to increasing activity levels. Level 5 provides the highest oxygen pulse volume for strenuous activities. It’s crucial to consult with your healthcare provider to determine the most appropriate setting for your specific condition.
Remember: Changes to the pulse setting take effect immediately. Monitor your oxygen saturation levels and adjust accordingly, always following your doctor’s guidance.
Battery Management and Charging
The CAIRE FreeStyle Comfort utilizes a rechargeable lithium-ion battery, providing extended portability. To maximize battery life, avoid fully discharging the battery frequently; instead, consider charging it when it reaches approximately 25% capacity. A complete charge typically takes several hours, using the provided AC/DC power adapter.
During charging, the battery icon on the LCD screen will pulse. Once fully charged, the icon will become solid. Avoid using non-CAIRE-approved chargers, as they may damage the battery or device. Store the battery in a cool, dry place when not in use.
Battery performance can vary based on usage patterns and environmental factors. Refer to the technical specifications section for detailed battery life information.
Safety and Maintenance
Prioritize safety by understanding alarm conditions and troubleshooting steps detailed in the user manual (MN250, MN233).
Regular cleaning and disinfection, following provided procedures, ensures optimal device performance and longevity.
Alarm Conditions and Troubleshooting
The FreeStyle Comfort incorporates several alarms to alert users to potential issues. Understanding these is crucial for safe operation. Refer to the user manual (MN250, MN233) for a complete list and detailed troubleshooting steps. Common alarms include low battery, high/low flow rate, and system malfunction.
Low battery alarms indicate the need for recharging. High/low flow rate alarms may suggest a cannula issue or device malfunction. System malfunction alarms require immediate attention and potentially contacting CAIRE Inc. for assistance. Always check the cannula for kinks or obstructions before assuming a device problem.
Troubleshooting often involves verifying power connections, ensuring proper filter maintenance, and reviewing the user manual’s diagnostic guide. If an alarm persists after troubleshooting, discontinue use and seek professional help. Ignoring alarms can compromise oxygen delivery and potentially endanger the user.
Cleaning and Disinfection Procedures
Maintaining cleanliness is vital for the safe and effective operation of your FreeStyle Comfort. Regular cleaning prevents the buildup of contaminants and ensures optimal performance. Refer to your user manual (MN250, MN233) for detailed instructions, as improper cleaning can damage the device.
Exterior surfaces should be wiped down with a damp, non-abrasive cloth and mild detergent. Avoid immersing the unit in water. The cannula and nasal prongs require more frequent cleaning; use warm, soapy water and rinse thoroughly. Disinfection can be achieved with isopropyl alcohol, following manufacturer’s guidelines.
Filters should be inspected and replaced regularly, as outlined in the manual. Proper cleaning and disinfection minimize the risk of infection and prolong the life of your CAIRE concentrator. Always ensure the device is powered off and disconnected before cleaning.
