Medical Information

What the VPAP III ST-A is Intended for

The VPAP III ST-A system is intended to provide non-invasive ventilation for patients with respiratory insufficiency or obstructive sleep apnea (OSA), in the hospital or home.

Contraindications

•

•

•

•

The VPAP III ST-A should not be used if you have an insufficient respiratory drive to endure brief interruptions in non-invasive ventilation therapy. The

VPAP III ST-A is not a life support ventilator and may stop operating with power failure or in the unlikely event of certain fault conditions.

If you have any of the following conditions, tell your doctor before using the

VPAP III ST-A: acute sinusitis or otitis media epistaxis causing a risk of pulmonary aspiration conditions predisposing to a risk of aspiration of gastric contents impaired ability to clear secretions

The entire manual should be read before using the VPAP III ST-A.

Advice contained in this manual should not supersede instructions given by the prescribing physician.

The VPAP III ST-A should be used with masks and accessories recommended by ResMed or the prescribing physician. Use of incorrect masks and accessories may adversely affect the function of the VPAP III ST-A.

The VPAP III ST-A is designed for use with masks that allow exhaled gases to be flushed out through vent holes. Exhaled gases will be rebreathed if the mask is worn with the machine turned off, or the vent holes are occluded. If this occurs over prolonged periods, suffocation may occur.

In the event of power failure or machine malfunction, remove the mask.

The VPAP III ST-A can be set to deliver pressures up to 30 cm H

O. In the unlikely event of certain fault conditions, pressures up to 40 cm H

2 possible.

O are

The VPAP III ST-A is not suitable for use in the vicinity of flammable anesthetics.

The VPAP III ST-A should not be used with anesthetized patients, whose breathing depends entirely on mechanical ventilation.

If oxygen is used with the VPAP III ST-A, the oxygen flow should be stopped when the device is not operating. If oxygen flow continues when the device is not operating, oxygen may accumulate within the device and create a risk of fire.

Do not use the VPAP III ST-A if there are obvious external defects, unexplained changes in performance or unusual noises.

Do not open the VPAP III ST-A case. There are no user serviceable parts inside. Repairs and internal servicing should only be performed by an authorized service agent.

Cautions

•

•

At low EPAP pressures, the flow through the mask vent holes may be inadequate to clear all exhaled gases, and some rebreathing may occur.

The air flow for breathing produced by this device can be as much as 6 o

C higher than the temperature of the room. Caution should be exercised if the room temperature is warmer than 32 o C.

Note: The above are general warnings and cautions. Further specific warnings, cautions and notes appear next to the relevant instructions in the manual.

Adverse Effects

•

•

•

•

•

•

You should report unusual chest pain, severe headache or increased breathlessness to your physician. An acute upper respiratory tract infection may require temporary discontinuation of treatment.

The following side effects may arise during the course of therapy with the

VPAP III ST-A: drying of the nose, mouth or throat bloating ear or sinus discomfort eye irritation mask-related skin irritations chest discomfort.

The mask-fitting feature delivers air pressure for a three-minute period, prior to starting treatment, for checking and adjusting your mask fit to minimize leaks. If a Ramp time is selected, the mask can be adjusted at a pressure closer to the prescribed pressure. To use the mask-fitting feature:

1. Fit your mask as described in the user instructions.

2. Hold down the Start/Stop key for at least three seconds until air pressure delivery starts.

The following display will appear on the LCD screen indicating that the mask-fitting feature is in operation. The flow generator will ramp to the Mask-

Fit pressure and will remain at this pressure for three minutes. A Mask-Fit star rating is also displayed. See “Definitions of Mask-Fit Star Rating” on page 15.

How to Use the VPAP III ST-A Menus

The VPAP III ST-A provides a set of functions arranged in menus and submenus.

Via the LCD screen, the menus and submenus allow you to view and change the settings for a particular function. You can access the menus regardless of whether the VPAP III ST-A is in standby mode or delivering therapy.

Your clinician has preset the menu to either a standard view or a detailed view.

Both of these menus are explained below.

When the VPAP III ST-A is turned on, a Welcome screen is displayed. After the device self-checks are complete, the VPAP (or Ramp) screen appears.

Ramp Screen

If your clinician has set a maximum ramp time, the Ramp screen is displayed after the Welcome screen. On the Ramp screen, you can immediately set a ramp time. Ramp time is the period during which the pressure increases from a low pressure to the prescribed treatment pressure. See “Ramp Time” on page 13.

Ramp time can be altered in five-minute increments (from OFF to a maximum ramp time set by your clinician) by using the Up/Down key.

How to Use the Standard Menu

The standard menu allows you to view details about the time used, a summary of your device settings, and the current software version of your VPAP III ST-A.

The Used (time) screen displays the total number of hours for which the device has been used. It also displays the number of days the VPAP III ST-A was used out of the total number of days available for use.

For details on the settings summary screens, see “Settings Summary Screens” on page 20.

Helpful Hints

Starting out

Mouth Leaks

If using a nasal mask, try to keep your mouth closed during treatment. Air leaks from your mouth can decrease the effectiveness of your treatment. If mouth leaks are a problem, a full face mask or chin strap may help. Contact your clinician or equipment supplier for further details.

Mask Fitting

The flow generator delivers the most effective treatment when the mask is well fitted and comfortable. Treatment can be affected by leaks, so it is important to eliminate any leaks that may arise.

If you have problems trying to get a comfortable mask fit, contact your clinician or equipment supplier. You may benefit from a different size or style of mask.

You can also use the Mask-Fitting feature to help you fit your mask properly. See

“Using the Mask-Fitting Feature” on page 14.

Before wearing your mask, wash your face to remove excess facial oils. This will allow a better fit and prolong the life of the mask cushion.

Nasal Irritation

Dryness

You may experience dryness of the nose, mouth and/or throat during the course of treatment, especially during winter. In many cases, a humidifier may resolve this discomfort. Contact your clinician for advice.

Runny or Blocked Nose

You may experience sneezing and/or a runny or blocked nose during the first few weeks of treatment. In many cases, nasal irritation can be resolved with a humidifier. Consult your clinican for advice.

Travelling with the VPAP III ST-A

International Use

Your VPAP III ST-A flow generator has an internal power adapter that enables it to operate in other countries. It will operate on power supplies of 100–240V and

50–60Hz. No special adjustment is necessary, but you will require an approved power cord for that country.

Using a Battery to Power the VPAP III ST-A

The VPAP III ST-A can be powered by battery using the ResMed DC-24/30

Converter, an inverter or a UPS (uninterruptible power supply).

Battery Requirements

We recommend a 12V or 24V deep-cycle battery. Battery capacity is determined by VPAP III ST-A's power consumption which is mainly affected by the IPAP pressure, usage hours and whether or not an integrated humidifier is connected.

Helpful Hints 33

34

Please refer to the VPAP III Series Battery Power Guide for the recommended battery type and capacity, or contact ResMed's Technical Services division for your specific application.

ResMed DC-24/30 Converter

ResMed supplies the DC-24/30 Converter (product code: 22015) which is compatible with the DC input of the VPAP III ST-A. This is an accessory that may be purchased separately through your ResMed distributor.

The DC-24/30 Converter can be connected to a 12V or 24V battery, or a cigarette lighter socket (in a vehicle). When using a DC power supply, the power is turned on and off via the switch on the converter, and not the power switch at the back of the VPAP III ST-A. No power will be supplied to the HumidAire 2i integrated humidifier when connected to a VPAP III ST-A using a converter.

Please refer to the DC-24/30 Converter instructions for further details.

Inverter or UPS

The power specifications for an inverter or a UPS are listed in the following table.

NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.

NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.

a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the VPAP III ST-A is used exceeds the applicable RF compliance level above, the VPAP III ST-A should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the VPAP III ST-A.

b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
