  • Pulse dose settings can be changed from 1-6 in one-half increments
  • Unit can be turned on and off
Batteries and Electrical Power

How many hours can EverGo batteries last before they need to be recharged?
EverGo’s two-battery system helps to ensure long operation duration times. For example, at a setting of 2 and 20 breaths per minute (BPM) with 2 fully charged batteries, the device can be expected to run for 8 hours. Under similar conditions at a setting of 4, 5, or 6, it can run for 4 hours.

The duration times shown in the table below are based on two fully charged batteries. If only one battery is used, duration will be approximately half of the times shown in the chart.

Flow Setting Rate of 20 BPM
1 12 hours
2 8 hours
3 6 hours
4 4 hours
5 4 hours
6 4 hours

How can a patient tell how much battery life is remaining?
There are two methods for determining the remaining battery life. If a battery is inside the unit, the touch screen interface will indicate the remaining battery life of each battery. If a battery is outside of the unit, an LED indicator shows the amount of charge by percentage.

What is the battery recharge time?
Approximately 2-3 hours per battery

How can batteries be recharged?
Batteries can be charged one of two ways:

If the battery or batteries are inside EverGo, they can be charged by plugging into an AC or DC power source (wall outlet or in the car, for example) using either the AC or DC power cord.

If the batteries are outside EverGo, batteries can be charged using the external battery charger (optional accessory) that plugs into the wall.

How much electricity does EverGo use while plugged into a wall outlet?
110 watts at 100 VAC (charging)
120 watts at 240 VAC (charging)
70 watts (not charging)

Oxygen Delivery

What is the maximum oxygen capacity of EverGo?
The maximum oxygen delivery of the EverGo is 1050ml/min.

How long does it take EverGo to reach specified oxygen purity?
At start-up, the EverGo dose setting number will blink until the unit reaches normal oxygen purity, typically 2-3 minutes. It can take longer depending upon actual breath rate, setting and temperature.

What flow settings are available for EverGo?
EverGo is a pulse dose device, delivering oxygen in settings of 1-6 in ½ setting increments.

Does EverGo offer continuous flow?
No. 

Is EverGo a demand or pulse device?
EverGo is a pulse device and delivers a bolus of oxygen in the first 0.3 seconds of inspiration. 

Is EverGo recommended for stationary night-time use?
EverGo is designed to be used as a portable concentrator while a patient is ambulatory and is intended to be supplemented with a stationary concentrator, such as the Respironics Millennium or EverFlo. Respironics recommends that a patient considering EverGo for night-time use undergo overnight oximetry testing.

Is EverGo approved for pediatric use?
No. 

What is the oxygen concentration delivered by EverGo?
89% (±3%)

What is the altitude rating of EverGo?
Up to 8,000 feet (2450 meters)

Does EverGo have an OPI (oxygen percentage indicator) sensor?
Yes.

Maintenance

What patient maintenance is required with EverGo?
The only patient maintenance required is to clean the air inlet filter once a week and the EverGo case as needed.

What maintenance must be performed by a homecare provider on EverGo?
EverGo requires little routine maintenance. Recommended maintenance includes:

  • Gross particle filter – to be replaced as needed by the homecare provider.
  • Micro-felt filter – to be replaced as needed by the homecare provider.
  • Inlet filter – to be replaced as needed by the homecare provider.
Travel

Is EverGo approved for airline travel?
Yes. EverGo has been approved for use on commercial airlines by the FAA. Airline policies for traveling with an oxygen concentrator vary. Patients need to check with their airlines before flying with EverGo. Because Respironics must obtain individual permission from each airline for the use of EverGo during flight, the list of airlines is always being updated.
Current list of EverGo-approved airlines.

How is EverGo used during motor vehicle travel?
Use the EverGo DC power cord to plug into the vehicle’s cigarette lighter or DC power input. When EverGo is operating from a DC power source, the batteries installed in EverGo will begin recharging.

Can EverGo be plugged into a DC outlet while a car is not running?
No. Make sure the vehicle has been started before plugging in your DC power cord. If EverGo is operated using the DC power cord while the vehicle engine is turned off, it could deplete the vehicle’s battery.

Is EverGo allowed on trains or buses?
Most bus and train lines allow passengers to use portable oxygen concentrators, but we encourage patients to check with their transportation companies in advance regarding required permissions or existing restrictions.
