1. Introduction About this Manual

This manual is your introduction to the Flowtron ACS900 system. You must read and fully understand this manual before using the system. Use this manual to initially set up the system, and keep it as a reference for day-to-day routines and as a guide to maintenance. If you have any difficulties in setting-up or using the Flowtron ACS900 system, contact your local ArjoHuntleigh sales office, listed at the end of this manual.

Intended Use

The intended use of this product is to help prevent Deep Vein Thrombosis (DVT). The garments are single patient use only. It is not for use in the home healthcare environment. The Flowtron ACS900 system should be used as part of a prescribed plan of care (refer to “Indications” on page 3).

About the Flowtron ACS900 System

The application of external pneumatic compression has two effects: • Augments venous blood flow velocity, thereby reducing stasis. • Enhances fibrinolytic activity to reduce the risk of early clot formation. The system is comprised of a pump that can be used in conjunction with an extensive range of ArjoHuntleigh inflatable uniform (DVT), sequential (Tri Pulse) and foot garments. Refer to “Accessories” on page 27 for a complete list of the calf, calf & thigh and foot garments which can be used with the Flowtron ACS900 pump. The pump automatically adjusts to the correct therapy profile depending upon which garment type is connected. The tubeset is integral to the system and cannot be disconnected from the pump. The mains power supply is the primary power source for the pump. The pump incorporates an internal battery, which is a secondary power source to back up the pump in the event of failure of or disconnection from (accidental or deliberate) the mains power supply.

2. Clinical Applications Indications

The intended use of the Flowtron ACS900 system is to help prevent Deep Vein Thrombosis (DVT). The system should be combined with an individualised monitoring programme. This system represents one aspect of a DVT strategy; if the patient's condition changes, the overall therapy regimen should be reviewed by the prescribing clinician. The above are guidelines only and should not replace clinical judgement. Depending on the garment type used, other clinical applications are also appropriate. The foot garment, in particular, has a wide range of clinical applications. Full details for clinical applications are included in the packaging of every garment. The type of garment used on an individual patient must be specified by a physician.

Contraindications Uniform & Sequential Calf and Calf & Thigh Garments

Foot Garments

The system, when used with calf or calf & thigh garments, should not be used in the following conditions: 1. Severe arteriosclerosis or other ischemic vascular diseases. 2. Severe congestive cardiac failure or any condition where an increase of fluid to the heart may be detrimental. 3. Known or suspected acute deep vein thrombosis, thrombophlebitis or pulmonary embolism. 4. Any local condition in which the garments would interfere, including: • Gangrene • Recent skin graft • Dermatitis • On untreated, infected leg wounds. The system, when used with the foot garments, should not be used in the following conditions: 1. Severe congestive cardiac failure or any condition where an increase of fluid to the heart may be detrimental. 2. Known or suspected acute deep vein thrombosis, thrombophlebitis or pulmonary embolism.

3

3. Any local condition in which the garments would interfere, including: • Gangrene • Recent skin graft • Dermatitis • On untreated, infected leg wounds  If you are unsure of any contraindications refer to the patient’s physician before using the device. Cautions

1. Proper garment application and connection to the pump is essential. 2. Garments should be positioned in such a way that they do not create any potential for constant pressure points on the patient's limb. If using apparatus with straps or securing devices, for example lithotomy stirrups, make sure that the tubing is not placed inside the strap next to the patient’s skin, and regularly check the patient's skin for signs of redness or pressure points. The garment is most effective in preventing venous stasis when the garment air bladders are located in the posterior position. If the air bladders cannot be placed at the posterior, the garment can be rotated around the calf to alternative positions all of which will still help to prevent venous stasis. 3. Lower limb positioning in relation to the garment and tubing should also be considered particularly in a patient that is unconscious, cannot feel or has reduced sensation and/or ability to move their leg(s). 4. The patient’s skin should be inspected frequently during every shift.  Many patients are at risk for pressure ulcers on the heel. Use of the foot garments does not negate the necessity for heel protection and appropriate skin care. 5. Clinical judgement is required to determine if the patient's skin condition requires additional protective measures, or if the therapy should be discontinued and an alternative modality used. 6. Garments should be removed immediately if the patient experiences tingling, numbness, or pain, and the physician notified.

4

7. When used for DVT prevention, continuous external pneumatic compression is recommended until the patient is fully ambulatory. Uninterrupted use of the system is encouraged. 8. The system should be USED WITH CAUTION on patients with: • Insensitive extremities. • Diabetes. • Impaired circulation. • Fragile or impaired skin.  These are guidelines only and should not replace clinical judgement and experience. Guidelines and Recommendations General • The system should be initiated immediately once the risk of DVT formation is identified and the plan of Recommendations care has been prescribed. • If compression stockings are ordered by the physician, the clinician should ensure that the compression stockings are properly measured, applied and worn by the patient. Any compression stocking used should be routinely checked to ensure continued proper fit and application, in addition to assessing the condition of the skin. • Where appropriate, patients should be instructed in the proper use of the system, the purpose of therapy and that any problems should be reported to the nursing staff. • For surgical patients, the system should be applied to the patient preoperatively, prior to the induction of anaesthesia. • The system should be used continuously for no less than 72 hours post-operatively or until the patient becomes fully ambulatory. • If the garment cannot be applied to the operative limb during surgery, it may be applied to the limb once the patient reaches the recovery unit.
