User Case | How They Made the Choice
Ms. Zhang, 65 years old, a patient with chronic obstructive pulmonary disease
“I use the LS-J-02B, which has a nebulizer function. It combines oxygen inhalation and medication administration in one process. My son said I no longer need to go to the hospital for nebulization treatment.”
Teacher Li, Teaching in the High-Altitude Areas
“At an altitude of 3,500 meters, the 9L flow rate of the LS-J-02C has enabled me to give classes without feeling short of breath. The timing function also reminds me to perform maintenance in time.”
Ms. Wang, oxygen deficiency during pregnancy
“During the later stages of pregnancy, I often felt dizzy. I chose the LS-J-02E. The electric adjustment with five gears is very convenient. I can lower the gear at night to keep it quiet and not disturb my sleep.”
