Introduction The VPAP™ III ST-A is a bilevel pressure support ventilator specifically designed for non-invasive mask ventilation. This user manual contains the information you need for the correct use of your VPAP III ST-A.
User/Owner Responsibility The user or owner of this system shall have sole responsibility and liability for any injury to persons or damage to property resulting from: • operation which is not in accordance with the operating instructions supplied • maintenance or modifications carried out unless in accordance with authorized instructions and by authorized persons. Please read this manual carefully before use. This manual contains special terms and icons that appear in the margins to draw your attention to specific and important information. • Warning alerts you to possible injury. • Caution explains special measures for the safe and effective use of the device. • Note is an informative or helpful note.
Medical Information Indications for Use The VPAP III ST-A system is intended to provide non-invasive ventilation for adult patients (>66 lb) and pediatric patients aged 7 years or older (>40 lbs) with respiratory insufficiency or obstructive sleep apnea (OSA). The device is intended for use in the hospital or home.
CAUTION (USA ONLY) Federal law restricts this device to sale by or on the order of a physician.
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 • hypotension or significant intravascular volume depletion • pneumothorax or pneumomediastinum • recent cranial trauma or surgery. • •
Warnings 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 only be used with masks (and connectors)* recommended by ResMed, or by your physician or respiratory therapist. A mask should not be used unless the VPAP III ST-A is turned on and operating properly. The vent hole or holes associated with the mask should never be blocked. Explanation of the warning: The VPAP III ST-A is intended to be used with special masks (or connectors)* which have vent holes to allow continuous flow of air out of the mask. When the device is turned on and functioning properly, new air from the device flushes the exhaled air out through the mask vent holes. However, when the device is not operating, enough fresh air will not be provided through the mask, and the exhaled air may be rebreathed. Rebreathing of exhaled air for longer than several minutes can, in some circumstances, lead to suffocation. This applies to most models of CPAP and bilevel devices. • •
*Ports may be incorporated in the mask or in connectors that are near the mask.
• • •
• • •
In the event of power failure or machine malfunction, remove the mask. Children who are unable to remove the mask should be attended at all times during therapy. At low EPAP pressures, the flow through the exhalation port may be inadequate to clear all exhaled gas from the tubing. Some rebreathing may occur. The air flow for breathing produced by this device can be as much as 11oF higher than the temperature of the room. Caution should be exercised if the room temperature is warmer than 90oF. The VPAP III ST-A can be set to deliver pressures up to 30 cm H2O. In the unlikely event of certain fault conditions, pressures up to 40 cm H2O are possible. 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 on artificial ventilation. If oxygen is used with this device, the oxygen flow must be turned off when the device is not operating.
Explanation of the warning: When the device is not in operation, and the oxygen flow is left on, oxygen delivered into the ventilator tubing may accumulate within the device enclosure. Oxygen accumulated in the device enclosure will create a risk of fire. This warning applies to most types of flow generators. • Oxygen supports combustion. Oxygen should not be used while smoking or in the presence of an open flame. • Always ensure air flow is being generated by the device before the oxygen supply is turned on. • Always turn the oxygen supply off before stopping the air flow from the device. Note: At a fixed rate of supplemental oxygen flow, the inhaled oxygen concentration will vary, depending on where the oxygen is introduced, pressure settings, patient breathing pattern, mask selection, and leak rate. This warning applies to most types of CPAP and bilevel devices. 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 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 • skin rashes • chest discomfort. The above are general warnings and cautions. Further specific warnings, cautions, and notes appear next to the relevant instructions in the manual.
