SPECIAL NOTES

  • Please read this manual carefully before using this product and save it for future reference.
  • If you need assistance with this manual, Please contact your local DME or home health provider
  • The Stratus 5 is a prescription device. Use only the liter setting prescribed for you.
  • It is always recommended for critically ill patients to have a backup oxygen source in case of malfunction.
  • If patient experiences an adverse reaction contact physician or call 911 immediately.
  • In case of machine malfunction, contact the home medical equipment provider; do not attempt to disassemble the Stratus 5.
  • The Stratus 5 is not intended as life support, it is for supplemental oxygen use only. Patients with special needs may be  unable to understand the alarm features and should be well supervised while using an oxygen concentrator.
  • The Stratus 5 is for single patient use.
  • Do not adjust the flowmeter float beyond the red line position. Long-term use out of range will reduce the efficiency of the oxygen generator.

SAFETY NOTICE
Please read the following information carefully before Operating the oxygen concentrator

Warning
Special attention should be paid to reducing the risk of fire when using oxygen therapy. Any material that is flammable in the air  becomes extremely combustible and burns quickly when the oxygen concentration is high. For safety reasons, all ignitions should be kept away from the oxygen concentrator.
Oil, grease or petroleum substances are prone to strong spontaneous combustion when exposed to oxygen under pressure. These materials must be kept away from oxygen  concentrators, cannulas, connections, and other oxygen concentrator components. Do not use any lubricant unless recommended by 3B MEDICAL, INC. Do not smoke  while using an oxygen concentrator.

Tips for Optimal Performance of the Stratus 5

  • The Stratus 5 should remain upright during use and storage.

  • The Stratus 5 should be operated in a clean environment. Excessive dust and moisture can affect optimal performance.

  • Environmental temperatures for operation should remain between 50°F and 99°F.

  • The Stratus 5 should not be moved while in operation.

  • The Stratus 5 should not be turned on with the flow meter turned off or less than “0”.

  • The Stratus 5 will make an exhaust sound while in operation.

  • The Stratus 5 will vent hot air from the bottom of the unit; please do not block the vent.
    Blocking the vent increases risk of fire.

  • The Stratus 5 should be used for 30+ minutes at each session.
    Running the concentrator for short bursts can damage the components over time.

  • Do not use the Stratus 5 if the power cord is damaged, the concentrator has fallen or has been submerged in water.

  • If any of the above occurs, the unit is working incorrectly or abnormally, please contact your
    DME or home health company.

  • Do not move the Stratus 5 by pulling the power cord.

  • Do not insert foreign objects into any openings.

  • Do not block inlets, vents or exhaust ports of the Stratus 5.

  • Do not place the Stratus 5 on soft surfaces such as beds, sofas, blankets or cushions, this is a fire hazard.

  • Do not overfill the humidifier water bottle. This may cause water to enter the cannula or oxygen outlet port.

  • Please place the Stratus 5 at least 15 inches away from walls, curtains and other solid surfaces.

  • Do not stack objects on top of the Stratus 5.

  • Do not use parts, accessories, or equipment not approved by 3B MEDICAL, INC.

  • Do connect the concentrator in parallel or series with other oxygen concentrators or oxygen therapy devices.

  • Only use the Stratus 5 power cord made specifically for this device.

  • Oxygen therapy is a prescription. Flow rates are patient specific. Please do not change your flow without consulting your physician.

  • This machine is designed to supplement oxygen, not for first aid or to sustain life.

  • Avoid creating sparks near medical oxygen equipment, including static sparks generated by friction.

  • Extended use in sub-optimal conditions can affect oxygen purity. This may cause oxygen levels lower than the patient requires.

  • If you feel your oxygen therapy is not sufficient please contact your physician. DO NOT attempt to change your prescribed liter flow.

  • The power plug must be unplugged while the Stratus 5 concentrator is not in use.

  • Contact the physician immediately, if the patient or caregiver finds insufficient oxygen supply.
    Do not adjust the oxygen flow unless directed by a physician or healthcare professional.

  • Always unplug the Stratus 5 when performing any routine maintenance to avoid electric shock.

Maintenance

The 3B Stratus 5 is designed to minimize routine maintenance. Yearly maintenance must be performed by an authorized dealer or certified personnel only.

Radio frequency interference

  • The use of portable communication equipment near the oxygen concentrator may cause interference to the machine.
  • This product cannot be used in environments such as electrocautery, electrosurgery, defibrillation, X-ray (gamma ray), infrared radiation and transient electromagnetic  fields, including magnetic resonance (MRI) and radio interference.
  • Portable RF communications equipment (including peripherals such as antenna cables and external antennas) should be more than 12 inches from any part of the  equipment. Otherwise, the performance of the device may be affected.
  • This oxygen concentrator cannot be stacked with other equipment.
    This may result in improper operation.

Water Safety

  • Do not use while bathing. If the patient requires continuous O2, the Stratus 5 concentrator must be placed at least 10 feet from the bathroom.
  • Do not touch the oxygen concentrator while wet. Do not use or store this oxygen concentrator near liquids or other electrically conductive materials.
  • Do not touch the Stratus 5 if it should fall into water or other conductive liquid. If this should occur, unplug the power cord immediately.

Introduction

Your physician has prescribed an oxygen concentrator set at a specific flow setting to meet your needs. DO NOT change the flow settings unless your health care  professional tells you to do so. Please read and understand this entire manual before using the device.

Intended Use
The 3B Medical Stratus 5 Oxygen Concentrator is intended to provide supplemental oxygen to persons requiring oxygen therapy. The device is not intended to be life supporting or life sustaining.

About Stratus 5
The Stratus 5 produces concentrated oxygen from room air for delivery to a patient requiring low flow oxygen therapy. The oxygen from the air is concentrated using a  molecular sieve and a pressure swing adsorption process. Your home care provider will show you how to operate the concentrator and will be available to answer any  questions.

Parts of Oxygen Concentrator

  • Humidifier Band: The humidifier band secures the humidification bottle to the Stratus 5.
  • Oxygen outlet: the oxygen flows from this port
  • Oxygen flow meter: The flow meter indicates the liters per minute (lpm) that the oxygen is flowing from the oxygen outlet port
  • Power switch “ I ” indicates the unit is running
  • “ O ” indicates the power is off and oxygen is no longer being delivered to the patient

Intake filter: filters dust particles, this filter must not be removed by the patient
Filter Access Panel: allows authorized personnel to access the intake filter

Accessory Equipment and Spare Parts
