Three work modes separate the VENTMED DF-25S-HM Auto CPAP from the rest of the DF range. CPAP holds one pressure. AUTO adjusts within a 4 to 25 cmH2O band. Auto S is the addition, and it changes what the device can do. In Auto S, the machine sets an inspiratory pressure and an expiratory pressure independently, each configurable across 4 to 25 cmH2O.

The gap between them is the pressure difference, adjustable from 2 to 10 cmH2O. That difference is the support each breath receives. Two further controls shape how the device behaves in this mode. Pressure rise and fall time is set between 100 and 900 milliseconds, governing how sharply pressure changes between the two levels.

I/E sensitivity carries five levels, determining how readily the device switches with the patient's own effort. Comfort hardware matches the rest of the DF series. Humidification is heated across five levels, and the air tubing carries its own heating control from 10 to 30 degrees Celsius. Noise is rated at 22 dBA or less at 10 cmH2O.

A 3.5-inch colour screen shows live flow, pressure, outlet temperature, and humidity, alongside sleep and AHI reporting. Records write to a TF card and are held for more than five years. Mobile network access and the cloud platform remain optional rather than fitted as standard. The unit ships with a nasal mask, heated air tubing, power supply, five filters, a TF card, manual, and carrying bag.

Medigear.uk supplies it across the UK and will confirm the conformity route, warranty, and lead times before order.

Adults with obstructive sleep apnoea are the main patient group for this device. VENTMED describes the DF series as a single-level ventilator supporting sleep apnoea and hypoventilation syndrome. The condition narrows or closes the upper airway during sleep, interrupting breathing and dropping blood oxygen.

Pressurised air holds the airway open so breathing continues. Where the DF-25S-HM earns its place is the group that fixed pressure serves poorly. Some patients need high therapeutic pressure but cannot tolerate it as one constant level.

Exhaling against a strong airflow becomes tiring, and adherence falls away. Auto S answers that by dropping pressure on the breath out and raising it on the breath in. The pressure difference between the two, set from 2 to 10 cmH2O, is what the patient feels as support.

The wider 25 cmH2O ceiling matters for the same group, keeping high-requirement patients inside this device rather than moving them to a bilevel platform. Rise and fall timing and five-step I/E sensitivity let a clinician shape how the transitions feel, which often decides whether a patient continues.

Home therapy is the primary setting, with heated humidification and heated tubing addressing dryness and hose condensation. Sleep clinics use the device for home titration, drawing on TF card records and generated sleep reports.

Hospital respiratory teams use it during short admissions and when building home care packages. Optional cloud connectivity supports remote review where it has been specified.

Every pressure setting requires prescription and periodic review by a qualified clinician, and Medigear.uk provides the full instructions for use with each unit.

Bilevel Support Without Moving to a Bilevel Platform

Auto S delivers separate inspiratory and expiratory pressures inside an auto CPAP chassis, which suits services that need occasional pressure support but not a full ventilator.

Adjustable Pressure Difference from 2 to 10 cmH2O

The gap between inspiratory and expiratory settings is set deliberately, so the amount of support each breath receives becomes a clinical decision rather than a fixed product characteristic.

25 cmH2O Ceiling Across All Modes

Five centimetres of water above the DF-20A-HM keeps higher-requirement patients within this model instead of forcing a step up.

Transition Timing Under Clinical Control

Pressure rise and fall time from 100 to 900 milliseconds lets a clinician soften or sharpen the switch between pressures to suit the individual.

Five-Step Trigger Responsiveness

I/E sensitivity tuning across five levels matches cycling to a patient's own effort rather than applying one fixed threshold.

Heated Tubing Alongside Heated Water

Independent hose heating from 10 to 30 degrees Celsius targets condensation directly, which humidifier settings alone cannot resolve.

22 dBA Operation in Every Mode

The sponge-free silence box and patented noise reduction give a rating suitable for shared bedrooms and multi-bed bays alike.

Live Therapy Data on a 3.5 Inch Screen

Flow, pressure, outlet temperature, and humidity display together, with sleep and AHI reporting available without a separate reader.

More Than Five Years of Records

TF card storage covers a full therapy episode, supporting review of long-term trends rather than only recent nights.

Fleet and Single-Unit Supply Through Medigear.uk

Medigear.uk quotes the VENTMED DF-25S-HM Auto CPAP for NHS framework volumes and individual private practice orders on one account.

CPAP, AUTO, and Auto S Work Modes

Three modes cover fixed pressure, automatic adjustment, and bilevel delivery with independent settings.

4 to 25 cmH2O Pressure Range

Automatic adjustment operates across the full band, five above the DF-20A-HM ceiling.

Independent Inspiratory Pressure, 4 to 25 cmH2O

Inspiratory pressure is configured separately across the whole available range.

Independent Expiratory Pressure, 4 to 25 cmH2O

Expiratory pressure is set on its own scale, allowing a deliberate gap below the inspiratory figure.

Pressure Difference, 2 to 10 cmH2O

The permitted spread between the two pressures defines the support delivered on each breath.

Pressure Rise and Fall Time, 100 to 900 ms

Transition speed between pressure levels is adjustable to suit patient comfort.

I/E Sensitivity, 5 Levels

Cycling responsiveness is tuned across five steps to match individual breathing effort.

Heated Air Tubing, 10 to 30 Degrees Celsius

Hose temperature is adjustable in one-degree increments to prevent rainout reaching the mask.

Heated Humidification, Levels 1 to 5

Warmth and moisture are added at the source across five selectable settings.

22 dBA or Less at 10 cmH2O

Patented noise reduction and a sponge-free silence box hold operating noise low.

3.5 Inch Colour Display

Therapy values appear live, covering flow, pressure, outlet temperature, and outlet humidity.

Ramp Time, 0 to 60 Minutes

Pressure climbs gradually at the start of a session rather than arriving at the full setting.

TF Card Storage Beyond Five Years

Removable media holds a long therapy history for clinical review.

Optional Mobile Network and Cloud Platform

Cellular transmission and cloud reporting can be specified, enabling remote review between appointments.

Alarm Prompts and Oximeter Pairing

Alarms flag conditions that would compromise therapy, and a compatible VENTMED oximeter can display oxygen saturation on screen.

Positioned above the DF-20A-HM, the VENTMED DF-25S-HM Auto CPAP carries the same quiet chassis, heated tubing, and 3.5-inch display while adding the controls that matter for harder cases. Auto S brings independent inspiratory and expiratory pressures with an adjustable 2 to 10 cmH2O difference, supported by rise and fall timing and five-step I/E tuning, and the ceiling extends to 25 cmH2O. Services treating patients who cannot tolerate high fixed pressure will find that combination useful without committing to a full bilevel ventilator. Medigear.uk supplies the unit with its complete accessory kit for single orders or fleet volumes, and will confirm device and packing dimensions in LBH mm, water tank capacity, UK conformity route, and warranty terms, none of which are settled in the manufacturer material currently held.

FAQ

Frequently Asked Questions

Everything buyers need to know about sourcing medical equipment through MediGear.

Auto S delivers two pressures rather than one. A higher inspiratory pressure supports the breath in, and a lower expiratory pressure makes breathing out easier. Both are set across 4 to 25 cmH2O, with the gap between them constrained to 2 to 10 cmH2O. The device follows patient effort in switching between the two. Medigear.uk can supply VENTMED's configuration guidance for this mode.

VENTMED positions it within the DF series Auto CPAP range, but Auto S gives it bilevel behaviour with separate inspiratory and expiratory settings. Some retailers list it as an auto BiPAP, which overstates it, since there is no timed or ST mode and no backup rate. It is an auto CPAP with an added bilevel mode. Medigear.uk will confirm mode availability on any unit quoted.

All modes operate across 4 to 25 cmH2O. That is five above the DF-20A-HM ceiling. In Auto S, both inspiratory and expiratory pressures draw on the same range, with the permitted gap between them running from 2 to 10 cmH2O. Medigear.uk can provide the setup guide so a sleep service can check this against its prescribing protocol.

It controls how quickly the device moves between inspiratory and expiratory pressure, adjustable from 100 to 900 milliseconds. A short setting feels sharper and more responsive. A longer setting feels gentler. The right value depends on the individual, and it is one of the settings most worth revisiting if a patient reports the transition feels wrong. Medigear.uk supplies the full instructions for use.

I/E sensitivity determines how much patient effort is needed before the device switches between inspiratory and expiratory pressure. Five steps let a clinician tune that responsiveness to an individual breathing pattern. Set too low, the device lags; set too high, it can cycle on noise rather than genuine effort. Medigear.uk can arrange manufacturer guidance on typical starting values.

VENTMED rates the whole DF series at 22 dBA or less at 10 cmH2O, attributed to a sponge-free silence box and patented noise reduction. The rating is not broken down by work mode in the material supplied. Medigear.uk suggests requesting written acoustic test conditions if the figure is being relied on for a tender or a shared-room deployment.

Not as standard. VENTMED lists mobile network access and the data cloud platform as optional on this model. Whether a unit ships with the communication module depends on how it was ordered. Because this determines whether remote monitoring is possible at all, Medigear.uk will confirm the exact configuration in writing before a quotation is accepted.

They are not stated in the specification material supplied, and VENTMED has not published them in the sources checked. The manufacturer describes the DF series only as smaller and lighter than its earlier DS machines. Medigear.uk will obtain confirmed device and packing dimensions in LBH mm, plus net and gross weights, rather than carry over figures from another model.

VENTMED states CE and ISO 13485 certification for the DF range. The conformity route, certificate validity, UKCA position, and UK Responsible Person are not established in the material supplied. Warranty is quoted inconsistently across VENTMED's own listings, appearing as both one year and two years. Medigear.uk will settle each of these points before any unit is supplied.

The DF-20A-HM covers CPAP and AUTO to 20 cmH2O and suits most straightforward obstructive sleep apnoea. The DF-25S-HM lifts the ceiling to 25 cmH2O and adds Auto S with independent pressures, rise and fall timing, and I/E tuning. Patients needing pressure support or sitting above 20 cmH2O need this model. Medigear.uk quotes both side by side.
