Key Features of Portable Oxygen Machines
1. Flow Type: Pulse Dose vs Continuous Flow
- Pulse Dose: Delivers oxygen only when you inhale. This is much more efficient and allows for longer battery life and lighter machines. Most portable oxygen concentrators on the market are pulse dose.
- Continuous Flow: Provides a continuous stream of oxygen, regardless of your breathing cycle. It’s needed for some conditions—such as when you’re sleeping—or if your prescription specifies it.
- Dual Mode: Some advanced machines offer both, giving you flexibility for changing circumstances (such as being active during the day and needing continuous flow at night).
2. Oxygen Output and Settings
- Measured in liters per minute (LPM) or as discrete pulse settings (e.g., 1–6).
- Prescription determines your required flow rate. Portable models typically range from 0.25 to 2 LPM (continuous) or pulse settings 1–10.
- Higher settings reduce battery life but deliver more oxygen.
3. Portability and Weight
- Weight varies from ultra-light (2 lbs) to more robust models (6–18 lbs).
- Lighter models are easier to carry but may sacrifice maximum oxygen delivery or battery duration.
- Heavier or trolley-equipped models suit higher oxygen needs or overnight use.
4. Battery Life and Power Options
- Battery life ranges from about 2 to 13 hours on a single charge, depending on flow setting and battery type (single vs. double).
- Many models offer optional extended-life batteries for all-day outings.
- Most units can be charged via AC (home) or DC (car), with “hot swap” (change battery during use) on many models.
5. Noise Level
- Machines run at 39–44 decibels (dB) — comparable to a quiet conversation.
- Lower-noise models are ideal for discreet public use or sleep.
6. Smart Technology and Apps
- Some top models now feature mobile apps (Bluetooth connectivity), allowing you to monitor battery status, change settings, and run diagnostics via smartphone.
- Advanced sensors can adapt oxygen supply automatically to your breathing pattern.
7. Warranty & Support
