In the hospital corridor at dawn, Aunt Li was anxiously waiting for her follow-up examination. Her chronic obstructive pulmonary disease (COPD) has entered a stable stage, and the doctor recommended home oxygen therapy. But in the face of the dazzling array of oxygen generators, she was at a loss: the choice of flow rate, the trade-offs of functions, and the safety for the elderly to use… These decisions directly affect the treatment outcome. This article will reveal common misunderstandings and provide professional solutions.
Lecture 1: LS-J-01A Household Oxygen Generator (Standard Popular Type)
- Core features : oxygen flow rate 1-6L/min, negative oxygen ions ≥6 million /cm³, three-level electric adjustment (1L-90% concentration, 3L-40%, 6L-30%).
- Key points to avoid :
- Error : ignoring concentration decay. The higher the flow rate, the more significantly the oxygen concentration decreases. Adjustments should be made as per the doctor’s advice.
- Correct advice : COPD patients should prioritize low-flow (1-3 l /min) to maintain 90% concentration and avoid high-flow low-efficiency oxygen therapy.
- Success case : Mr. Zhang, a COPD patient, received oxygen therapy at the 1L level for 15 hours daily, and his blood oxygen saturation remained stable at over 95%.
Lecture 2: LS-J-01B Household Oxygen Generator (Standard Spray Type)
- Core features : Added atomization function, the rest is the same as LS-J-01A.
- Key points to avoid :
- Error : confusing nebulization with oxygen therapy. Nebulization requires the combination of medication and is not an independent treatment method.
- Correct advice : Patients with respiratory tract infections can choose this option first, but the use of the medication should be guided by a doctor.
- Applicable scenarios : multi-purpose in households, such as daily oxygen therapy for the elderly and occasional nebulization.
Lecture 3: LS-J-01C Household Oxygen Generator (High-End Configuration Type)
- Core features : Five-level electric adjustment (1L-90%, 2L-55%, 3L-40%, 5L-35%, 6L-30%), with cumulative timing.
- Key points to avoid :
- Error : ignoring the timing function. When using it for a long time, the duration should be recorded to avoid overuse or underuse.
- Correct advice : Patients with chronic diseases use the timing function to optimize their treatment plans.
- Success case : Ms. Zhao, a patient with pulmonary fibrosis, maintained a stable condition by adjusting the frequency of oxygen therapy through cumulative timing.
[Comparison of Five Flow Concentrations]
| Gear position | Flow rate (L/min） | Oxygen concentration (%) | Applicable scenarios |
| 1 gear | 1 | 90 | Stable period of chronic diseases |
| 2 gears | 2 | 55 | Light activity |
| 3 gears | 3 | 40 | Daily oxygen therapy |
| 4 gears | 4 | 35 | Moderate activity |
| 5 gears | 5 | 30 | High-intensity activities |
Lecture 4: LS-J-01D Household Oxygen Generator (High-End Spray Type)
- Core features : atomization + cumulative timing, five-level adjustment.
- Key points to avoid :
- Error : Improper atomization operation. Excessive intake of the liquid medicine or inhalation too quickly may cause discomfort.
- Correct advice : Dilute the medicine strictly as per the instructions and inhale slowly while sitting.
- Applicable scenarios : Comprehensive family treatment, such as COPD combined with respiratory tract infection.
Lecture 5: LS-J-01E Household Oxygen Generator (Luxury Spray Type)
- Core features : negative oxygen ions ≥12 million /cm³, atomization + cumulative timing, five-level adjustment.
- Key points to avoid :
- Error : excessive pursuit of high negative ions. Medical-grade oxygen therapy takes concentration as the core and negative ions as the auxiliary.
- Correct suggestion : Prioritize meeting the oxygen concentration requirement, and use negative ions as an environmental optimization option.
- Success case : Mr. Wang, an asthma patient, saw his attack frequency reduced by 50% when nebulization and oxygen therapy were used in combination.
Lecture 6: Common Points of the Five Products
- Technical basis : PSA pressure swing adsorption oxygen production, concentration 30%-90%.
- General parameters : AC110V/220V, noise 48db, size 325302168mm, net weight 5.2kg.
- Usage : ear-label type/nose suction type, suitable for vehicles, homes, outdoors.
