DF-925S BiPAP machine with flexible bilevel pressure from 4 to 25 cmH2O

Two Pressure Levels for More Natural Breathing

Unlike single-level pressure devices, the DF-925S supports separate inspiratory and expiratory pressure settings. It delivers a higher prescribed pressure during inhalation and transitions to a lower pressure during exhalation, helping provide synchronized bilevel respiratory support throughout each breathing cycle. In spontaneous breathing modes, the device detects the transition between inhalation and exhalation and switches between the preset pressure levels accordingly.

IPAP

4–25cmH₂O

EPAP

4–23cmH₂O

Made for Powerful Bilevel Support

The DF-925S BiPAP machine is designed to provide stable and comfortable pressurized airflow, with adjustable pressure up to 25 cmH₂O. It also features advanced ST mode with backup respiratory support and VGPSS mode with adjustable target tidal volume.

So the device is ideal for treating patients with sleep apnea and respiratory insufficiency, like OSA (Obstructive Sleep Apnea), CSA (Central Sleep Apnea), COPD (Chronic Obstructive Pulmonary Disease), OHS (Obesity Hypoventilation Syndrome) etc.

DF-925S BiPAP machine with ST mode and adjustable backup respiratory rate

ST Mode with Backup Rate Support (BUR)

In ST mode, a backup respiratory rate can be set from 3 to 50 breaths per minute (BPM). If the user’s spontaneous breathing rate falls below the prescribed setting, the DF-925S delivers timed bilevel pressure support to help maintain the configured breathing rhythm.

By supporting both inhalation and exhalation, the device may help reduce breathing effort and promote more effective ventilation during periods of insufficient spontaneous breathing.

Backup Rate

3–50 BPM

Inspiratory Time

0.3–4.0 sec

VGPSS Target Tidal Volume Support

VGPSS mode provides an additional therapy option for users who require a clinician-configured target tidal volume. The target tidal volume can be adjusted from 150 to 1500 mL in 50 mL increments, allowing the therapy settings to be adapted to individual ventilation requirements. In this mode, respiratory rate and inspiratory time can also be configured. The respiratory rate is adjustable from 3 to 50 BPM, while inspiratory time can be set from 0.3 to 4.0 seconds.

Target Tidal Volume

150–1500 mL

Respiratory Rate

DF-925S BiPAP machine with 0–60 minute adjustable ramp setting

Adjustable Ramp for a Gentler Therapy Start

Air pressure can be built up from a lower and easier level after the treatment begins when the user is still awake. Then pressure will be increased gradually and very comfortably to the target level after the user falls asleep. The ramp time can be set from 0 to 60 minutes in 5-minute increments. Users can select a shorter or longer ramp period according to the settings recommended by their healthcare professional.

Ramp Time

0–60 min

Adjustment Increment

5 min

Integrated Heated Humidifier

The integrated heated humidifier adds moisture to the airflow before it reaches the mask, helping reduce the dryness that some users may experience during extended therapy sessions. The humidification level can be adjusted from 33℃ to 55℃, allowing users to select an appropriate level according to environmental conditions and personal comfort.

Real-Time Therapy Monitoring

During therapy, the DF-925S displays important treatment and ventilation information directly on its color screen. This allows users and qualified healthcare professionals to view key operating data without needing a separate mobile application or external display.

The monitoring interface can show: VT(Tidal Volume), LV(Leak Volume), MV(Minute Ventilation), RR(Respiratory Rate), Current Working Mode, Treatment Pressure, Initial Pressure, Humidification Status, Ramp Status

Smart Configurable Safety Alerts

The DF-925S includes multiple configurable alerts designed to identify important changes in therapy or equipment operation. Available alert settings include: High Pressure Alert, Low Pressure Alert, High Breathing Rate Alert, Low Breathing Rate Alert, Low Minute Ventilation Alert, Apnea Alert, System Leak Alert, Mask or Tubing Disconnection Alert, Power Failure Alert.

Multiple Options for Your Convenience

Expiratory Relief

Choose from 0–5 pressure relief levels to reduce pressure during exhalation, helping each breath feel smoother and more comfortable during therapy.
Easy to Operate

Navigate settings easily using the clear display, rotary control knob and one-button operation, with adjustable brightness and screen sleep time.
Auto Start/Stop

Automatically starts therapy when you breathe into the mask and stops after removal, while manual Start/Stop control remains conveniently available.

Frequently Asked Questions

DF-925S BiPAP machine for comfortable nighttime use

What is a BiPAP machine, and how is it different from a CPAP machine?

A CPAP machine delivers one continuous pressure level during both inhalation and exhalation. A BiPAP machine provides two separate pressure levels—higher pressure during inhalation and lower pressure during exhalation—which may provide a more comfortable and personalized breathing experience for users who require prescribed bilevel therapy.

Who is the DF-925S BiPAP machine designed for?

The DF-925S is intended for adults weighing more than 30 kg who require prescribed non-invasive bilevel ventilation therapy for sleep apnea or hypoventilation syndrome. It can be used at home or in a healthcare facility under the direction of a qualified healthcare professional.

What pressure range does the DF-925S support?

The DF-925S supports flexible bilevel pressure settings with an inspiratory pressure range of 4–25 cmH₂O and an expiratory pressure range of 4–23 cmH₂O.

The machine automatically transitions between the prescribed inhalation and exhalation pressure levels according to the selected therapy mode. Pressure settings should be configured according to professional medical guidance.

What therapy modes are available?

The DF-925S supports seven therapy modes:

CPAP · APAP · BiPAP · S · T · ST · VGPSS

These modes provide options ranging from fixed-pressure therapy to spontaneous, timed and target tidal volume support. The appropriate mode should be selected by a qualified healthcare professional according to the user’s prescribed therapy requirements.

What is ST mode on a BiPAP machine?

ST mode combines spontaneous breathing support with a timed backup function. When the user is breathing spontaneously, the machine follows the breathing pattern and switches between the prescribed inspiratory and expiratory pressures.

If spontaneous breathing is not detected within the configured cycle, the device provides timed pressure support according to the prescribed backup rate.

Backup Respiratory Rate: 3–50 BPM
Inspiratory Time: 0.3–4.0 seconds

Does the DF-925S store therapy data?

Yes. Treatment sessions lasting more than 15 minutes are recorded internally. Therapy information can also be transferred to the included TF card for later review or export.
