A. Not automatically. A pulse‑dose setting of 3 on the Inogen One G5 is not equivalent to 3 LPM continuous flow, especially during sleep. Whether it is safe depends on the patient’s ability to reliably trigger the device during sleep and their maintained oxygen saturation and if the device has low/no flow detection that clears the device for sleep. A patient stable at 3 LPM continuous flow may receive less oxygen overall if they use pulse delivery as bolus doses of oxygen may be delivered inconsistently or may be missed during sleep. During sleep, Breathing is shallower and slower, and mouth breathing is more common. These factors can lead to missed or delayed triggers on pulse dose devices.

Some pulse dose devices are equipped with a backup response when no breath is detected or triggered however not all systems have this. While the Inogen G5 is cleared for sleep, the manufacturer emphasizes that it is not life-sustaining and requires patient-specific assessment. Consult your healthcare provider to assess if the patient may be clinically acceptable to sleep on a cleared pulse-dose device.

A. With 50 feet of tubing, you should still be receiving prescribed 4 LPM of oxygen. Make sure your tubing is not kinked, clogged, and clear of debris. If it is kinked at any point of the tubing, you will not be getting the oxygen liter flow. Make sure you change your tubing every month to help prevent the kinking and twisting up. You can ask your Delivery Technician to come out to check the liter flow from the mache with the 50 foot tubing attached.
