The Topson LC-APAP Auto CPAP is an advanced respiratory therapy device designed for people suffering from Obstructive Sleep Apnea (OSA). Unlike traditional CPAP machines that deliver a fixed pressure, this APAP system automatically adjusts the air pressure throughout the night based on your breathing pattern.
This ensures two things:

1. Maximum comfort – lower pressure when you don’t need more airflow

2. Maximum effectiveness – higher pressure only when your airway starts narrowing

This intelligent pressure adjustment helps improve therapy compliance, reduces discomfort, and enhances overall sleep quality.

Its compact size, low-noise motor, and easy-to-use interface make it ideal for daily home use as well as travel. The Topson LC-APAP is especially suitable for first-time CPAP users who want a smoother and more comfortable therapy experience.

Key Features Explained Clearly

1. Auto-Adjusting Pressure (APAP Mode)

The machine continuously monitors your breathing.
If your airway starts collapsing, it gently increases pressure.
If your breathing becomes stable again, the pressure automatically reduces.
This gives you only the amount of pressure you actually need.

2. Expiratory Pressure Relief (EPR)

Breathing out against high pressure can be uncomfortable.
EPR lowers the pressure slightly during exhalation, making it easier and more natural to breathe.

3. Ramp Function for Smooth Start

You can set a ramp time between 0 to 60 minutes.
The machine starts at a low pressure (easy on the lungs) and slowly rises to the prescribed range.
This helps you fall asleep without feeling air pressure immediately.

4. Leak Detection & Compensation

If the mask leaks at night, the machine automatically adjusts airflow so your therapy remains effective without interruptions.

5. Quiet Motor

Works at below 30 dB, quieter than a soft whisper.
Ideal for light sleepers or shared bedrooms.

6. Therapy Monitoring

The machine records:

• Usage hours

• Pressure changes

• Breathing events

• Mask leaks

This helps doctors evaluate your treatment and make corrections if needed.

7. Compact & Travel-Ready

Small body, under 1 kg weight, and a travel-friendly design makes it convenient to carry anywhere.
