The pulse mode provides oxygen when it detects the user's breath and maintains a stable concentration of 90±5%. You can set the flow rate from 1 to 6 levels. At levels 1-5, if no inhalation is detected within 6 seconds, it will automatically switch to supplying oxygen once every 3 seconds. At level 6, it will automatically supply oxygen at a higher frequency, approximately once every 1.5 seconds.
