1. Introduction About this Manual

This manual is your introduction to the Flowtron® ACS 800 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 ACS 800 system, contact your local ArjoHuntleigh sales office, listed at the end of this manual.

Intended Use

The intended use of this product is to prevent Deep Vein Thrombosis (DVT). The garments are single patient use only. It is not for use in the home healthcare environment. The Flowtron ACS 800 system should be used as part of a prescribed plan of care (refer to “Indications” on page 3).

About Flowtron ACS 800

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 comprises a pump that can be used in conjunction with an extensive range of ArjoHuntleigh inflatable garments, including foot, calf and calf & thigh versions. The pump automatically adjusts to the correct therapy profile depending upon which garment type (foot, calf or calf & thigh) 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 pack, which is a secondary power source to back up the pump in the event of failure or disconnection (accidentally or deliberately) from the mains power supply. The Flowtron ACS 800 system is intended for use ONLY in Professional Healthcare Facilities (e.g. hospitals or physicians’ offices). 1

2. Clinical Applications Indications

The primary application of the Flowtron ACS 800 system is for the prevention of Deep Vein Thrombosis (DVT) when 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 FG 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 DVT Calf / Thigh Garments

Foot Garments

The Flowtron ACS 800 system, when used with the DVT 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 Flowtron ACS 800 system, when used with the Foot Garments, should not be used in the following conditions: 1.

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. Additional care should be taken when placing the garments on any deformed leg or foot, or on legs with significant oedema. 3. Garments should be removed immediately if the patient experiences tingling, numbness, or pain, and the physician notified. 4. When used for DVT prevention, continuous external pneumatic compression is recommended until the patient is fully ambulatory. Uninterrupted use of the Flowtron ACS 800 system is encouraged. 5. The Flowtron ACS 800 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 • While using the system, the patient’s limbs should be checked during every shift, and more often if the Recommendations patient has known circulatory or skin problems, or is diabetic. • Note: 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 proper skin care. • Clinical judgment should be used to determine if the patient’s skin condition requires additional measures,

DVT Prophylaxis

or if the treatment should be discontinued and alternative modalities used. • ArjoHuntleigh does not recommend the use of compression stockings with its system. If these 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. • The Flowtron ACS 800 system should be applied to the patient pre-operatively, 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. • In the non-surgical patient, the system should be initiated immediately the risk of DVT formation is identified.

Battery Indication

Options

There are two “leg” icons with no garments attached and the text “Attach garments” at the top of the screen; this indicates that no garments are currently connected to either tubeset.  There is no text above the Start/Stop button until at least one garment is connected to a tubeset. Apply the prescribed ArjoHuntleigh garment(s) to the patient by following the instructions included in the garment packaging.

11

 Garments are for single patient use only. Do not use the garments on a different patient after treatment. Connect the garment(s) to the pump by pushing the garment connector firmly into the pump tubeset connector until it “clicks”. The pump LCD screen will show which garments are connected to each tubeset connector: the garment connector with the blue push button is “1” and the one with the orange push button is “2”. If any pump options (Audio Alarm Volume, Patient Hours Meter or Language) need to be changed, they must be changed before the patient therapy is started. Refer to “Changing Options” on page 16. The following four screens show typical Standby screens with different garment configurations:

Make sure the garment(s) are fitted correctly to the patient and the pump. Make sure any pump options have been changed if necessary.  If the pump is to be positioned under a bed, make sure it is placed horizontally (with the bed-hooks underneath) to prevent damage to the pump. While the pump is in Standby, the LEDs on the front case remain extinguished.

12

Press the button below “Start” to start the therapy. The LEDs on the front case change to static green. It is recommended that the following checks are carried out at the start of, and throughout, the therapy: • Check the LCD screen icons to confirm that the correct type of garment(s) have been connected. • During garment inflation, check the LCD screen to confirm that the correct pressure is being applied and that there are no fault messages displayed. The inflation pressures for the different garments are: • Foot Garment: 130 mmHg. • Calf and Calf & Thigh Garments: 40 mmHg.  Initial inflation cycles (up to 10) may not show the correct inflation pressure. This is to be expected. • Check that there are no kinks in the pump tubesets. • Check that the pump tubesets and connectors do not cause the patient any discomfort. • Regularly check that the garments remain correctly fitted to the patient. The pump will inflate and deflate each garment in turn, as follows, starting with garment 1:  The following example shows two foot garments fitted to the pump. 1. Both garments are initially deflated. The garment pressure is displayed on the left side of the screen. If the Patient Hours Meter is selected in the “Options” menu (refer to “Changing Options” on page 16), the total elapsed time (in hours) is shown in the bottom right of the screen:

3. The foot garment is deflated to zero. Both garment indicators are grey:

Stop

4. Foot garment 2 is then inflated to 130 mmHg, with a ramp up and hold time of 3 seconds. The foot garment indicator is black while it is inflated:

Stop

5. The foot garment is deflated to zero. Both garment indicators are grey:

Stop

6. This cycle of alternate garment inflations repeats from step 2 (above) until the therapy is stopped. If one or two calf (or calf & thigh) garments are attached to the pump, then each garment is inflated to 40 mmHg, with a ramp up and hold time of 12 seconds. If a foot garment and a calf (or calf & thigh) garment are attached to the pump, then since the inflate and hold 14

times for a foot garment are shorter than for a calf (or calf & thigh) garment, there is a modified inflation sequence: the foot garment is always inflated twice in succession and then the calf (or calf and thigh) garment is inflated, as follows.  The first garment to be inflated is always garment 1. 1. Inflate the foot garment to 130 mmHg. 2. Deflate the foot garment. 3. Repeat the inflation of the foot garment to 130 mmHg. 4. Deflate the foot garment. 5. Inflate the calf (or calf & thigh) garment to 40 mmHg. 6. Deflate the calf (or calf & thigh) garment. 7. This cycle of garment inflations repeats from step 1 (above) until the therapy is stopped. Stopping Therapy

To stop the therapy and put the pump into Standby, press and hold the Start/Stop button for approximately 2 seconds until the Standby screen is displayed (refer to “Standby Screens” on page 11) and then release it. The LED indicator by the On/Off button changes to amber and the LEDs on the front case are extinguished. If the pump stays in Standby, then: 1. After 5 minutes the LCD display backlight is dimmed. 2. After a further 15 minutes (20 minutes total) the pump automatically switches off.  The LED indicator will remain amber if the pump is connected to the mains power and extinguished if the mains power is disconnected.

Switching Off the Pump

1. Make sure the therapy is stopped and the pump is in Standby (refer to “Stopping Therapy” on page 15). 2. Press and hold the On/Off button for approximately 2 seconds until the LCD screen goes blank and then release it.  The LED indicator will remain amber if the pump is connected to the mains power and extinguished if the mains power is disconnected.

Alarms

On detection of a fault condition, the Flowtron ACS 800 pump provides a visual-only warning followed by an audible and visual alarm if the fault is not cleared.
