Other factors may also aect the
dose of the compression, for example the person’s height, or if they have an occupation where they are standing all day (It is worthy of note that other types of non- compression bandages such as crepe bandages fall within the Type 2 bandage category within the British National Formulary).

The term ‘two- layer’ should be rejected
because in very thin limbs only one layer may be used. Similarly, in advanced practice layering is applied in a specialist manner that does not sit within two- layer frame works. In standard care inelastic bandages are applied at full stretch in a spiral manner with a 50% overlap; in advanced practice this can vary.

and 3 bandage categories, therefore bandages outside of these cat­egories are not discussed.
Adjustable Wrap Systems
Wraps consist of a liner underlayer that serves to protect the skin and an overlayer that is the wrap itself. This is made from a low elastic material section that wraps across and around the limb and is secured with hook and loop or Velcro® fasteners. They are designed for self­application or in partnership with the practitioner and are therefore well suited to self- care and shared care approaches. They are availa­ble in dierent sizes and thus education is necessary for the practi­tioner to ensure correct measurements. Wraps are available for dierent areas of the lower limb including foot, calf, knee and thigh pieces (Ritchie and Freeman2018). There is also a variety of materi­als available for dierent uses. The Velcro wrap systems signicantly reduce the limb circumference and improve the tissue density, which can be particularly helpful in challenging brosed tissues. A combi­nation of wraps can be used to support the lower limb, for example foot and calf. Wraps can also be used in conjunction with other thera­pies, for example a compression bandage could be used to manage the gaiter ulceration and a knee wrap above may provide treatment for a swollen knee (Ritchie and Freeman2018).
Whichever tool has been selected, it is important to monitor the eectiveness of the intervention to ensure that the patient heals. Table8.17 details how to monitor if the therapy is working.

LOCATION OFTHE ULCERATION
The location of a wound frequently brings its own challenges for healing. Within the wider context of the body, wounds for example on the sacrum may be complex due to the risk of cross- contamination with body uids. The scalp brings its own challenges due to a thin layer of dermis and hypodermis and the presence of hair. Leg ulcera­tion is no dierent: a wound on the leg will often be harder to heal than a wound on the arm, purely due to the dierent eects of grav­ity on the arm compared to the leg. The exact location of the ulcera­tion on the lower limb adds to this complexity. In particular wounds in the retro malleolar area can be dicult to heal. The reason is that for many patients the retro malleolar fossa is deep, and even when eective high compression therapy is applied a ‘hammocking’ eect can occur, where the ulceration sits deeper within the fossa and so receives little if any compression. In cases such as this more advanced techniques such as fan strapping may be required (Hopkins et al. 2011). These techniques go beyond standard practice and require additional training. If people are identied as not healing and they have ulceration in this area, then referral for bespoke or specialist intervention is needed.
COMPRESSION OFTHE FOOT
A myth exists that the foot should not be compressed. This myth requires challenge and comparison if practitioners are fearful. The comparison is that the foot is compressed in leg ulcer hosiery kits, the foot is compressed in compression hosiery stockings, so why would we not compress the foot when using bandages as a therapy? Indeed, not encasing and protecting the foot leaves it vulnerable. Pascal’s law assures us that if eective compression therapy is applied on a uid (such as a muscle group) in a closed container (fascia muscularis and compression bandage), there is an equal increase at every other point in the container (leg) (Schuren and Mohr2010). However, when the uid is moved out of the area where compression is applied, there can be a risk to that tissue if not managed as the uid is shunted thereby the compression. This can be the foot, the toes or the knee, so these surrounding areas require protection through skilled

compression. Compression to the foot also augments the foot muscle pump and can improve walking (see Chapter4).
INTERMITTENT PNEUMATIC COMPRESSION
Intermittent pneumatic compression (IPC) is a mechanical device that can be used to aid in the healing of several types of ulcers, includ­ing venous leg ulcers (Nelson etal.2014), and can help reduce oedema in patients with lymphoedema (Desai and Shao2020). See Table8.18 for the types of ulceration that an IPC device may be suitable for.
When applied to the lower limb or thigh (depending on which device is used), IPC comes with a sleeve or cu that is attached to a motorised machine. The sleeve/cu has cycles of ination and dea­tion that vary in time depending on the device used. An IPC device comes in a variety of dierent cus/sleeves ranging from foot, below knee and up to the thigh. In recent years advances in IPC technology mean that the device can be applied to targeted areas of the body. This is an advantage for patients who have lower limb ulceration, as the device can be applied and used without squeezing over the site of pain and ulceration. For example, even if the venous leg ulcer is located on the lower leg below the knee, the application of the IPC device on the thigh is still therapeutic (Partsch etal.2002).
IPC encourages circulation by decreasing venous stasis and improving arterial ow, improving microcirculation and lymphatic drainage and reducing the production of inammatory mediators

(Young etal.2021). Naik etal. (2019) also highlight the biomechani­cal eects of IPC therapy, when the endothelial cells release antithrombotic, pro- brinolytic and vasodilatory properties that aid in the prevention of clot formation. See Table8.19 for the indications and contraindications of IPC therapy.
IPC is an adjunct therapy to compression therapy. Optimal dose compression therapy should always be considered as the mainstay of treatment in lower limb ulceration. IPC can be used intermittently or for a set period of time as part of the overall treatment plan, not instead of compression therapy (Young etal.2021).
WOUND BED PREPARATION AND CLINICAL MANAGEMENT
While compression is the key to managing most types of lower limb ulceration, it is also important that appropriate wound bed prepara­tion and dressing selection are undertaken. Chapter5 explained how to undertake a robust assessment using the TIMES framework. From this assessment three steps to wound bed preparation are advocated, which are explained in Table8.20.

Regular wound hygiene to
include wound bed cleansing and debridement (Wounds UK2022).
Wash surrounding limb as
discussed earlier in this chapter.
Cleanse the wound to ensure
removal of debris, exudate or dressing remnants. This should include the wound bed and wound margins.
Undertake mechanical
debridement to physically remove any devitalised tissue.
Identication of biolm (IWII2016) and
challenge if present with mechanical debridement and application of a topical antimicrobial (Malone etal.2017; Wounds UK2020).
Key indicators of biolm
presence include:
Recurrence of delayed healing on
cessation of antimicrobial administration.
Increased exudate levels.Low- level chronic inammation.Low- level erythema.Poor granulation tissue or friable
tissue that bleeds easily.
Hypergranulation.Wound breakdown and enlargement.
Challenge biolm by undertaking
mechanical debridement at least three times a week to disrupt the protective matrix covering the micro- organisms so that topical antimicrobial can penetrate to the micro- organisms.
Apply a topical antimicrobial for a
maximum of two weeks, then review.
Application of an appropriate dressing.
Dressings do not heal wounds; the body heals
wounds, given the right nutrition and hydration. In the case of the lower limb, due to underlying pathophysiology and the eects of gravity, compression therapy is key to healing and should be the key focus, not the type of dressing.
Dressings should be selected for their ability to
provide a contact layer between the leg and the compression tool being used, to support autolytic debridement, maintain moisture balance and manage exudate (see the earlier section of this chapter for more details on exudate management).

CONCLUSION
This chapter has examined clinical management, employing a frame­work that will assess the person, assess the limb and assess the leg. The overarching aim is to create healing, but it is also important that other goals such as a personalised approach to care are adopted. Ensuring the person is left with as good a limb shape as possible is also a primary consideration, as of course is thinking ahead to the future and the prevention of ulcer reoccurrence caused by this long­term condition. Chapter 9 will examine the prevention of reoccur­rence and the use of compression hosiery stockings.
