“…3,4 Unfortunately, these methods cannot predict the progress of healing. Pulse oximetry can measure oxygen saturation and detect poorly healing areas, 5,6 but its output may be influenced by patients' movement and can be unreliable. 7 Several imaging techniques, such as ultrasound imaging, magnetic resonance imaging, laser Doppler perfusion imaging, are also used to confirm ischemic or venous etiology for the wound and the presence of infection or ischemia.…”

Objective: While myriads of studies have suggested that a survey of wound pH environment could indicate wound healing activities, it is not clear whether wound alkalinity can be used as a prognostic indicator of nonhealing wounds. Currently available systems cannot reliably assess the pH environment across wounds, which is the objective of this study. Approach: A disposable device, DETEC Ò pH, was developed and characterized on its ability to map wound alkalinity by pressing a freshly recovered wound dressing against its test surface. By comparing the wound's alkalinity and size reduction rates (*7 days) following pH measurement, we assessed the capability of wound alkalinity to prognosticate subsequent short-term wound size reduction rates. Results: The device had high accuracy and specificity in determining the alkalinity of simulated wound fluids soaked onto wound dressing. The type of wound dressing type had an insignificant effect on its detection sensitivity. Upon testing discarded wound dressings from human patients, the device quickly determined alkaline and acidic wounds. Finally, statistical analyses of wound size reduction rates in wounds with various alkalinities confirmed that wound alkalinity has a strong influence on, at least, short-term wound healing activity. Innovation: Without directly contacting the patient, this device provides a quick assessment of wound alkalinity to prognosticate immediate and short-term wound healing activities. Conclusion: DETEC Ò pH may serve as a prognosis device for wound care specialists during routine wound assessment to predict wound healing progress. This information can assist the decision-making process in a clinical setting and augur well for chronic wound treatment. DETEC Ò pH can also be used as an aid for home health care nurses or health care providers to screen nonhealing wounds outside clinics.

“…Another popular and noninvasive wound measurement tool is the pulse oximeter that measures oxygen saturation within the patient's blood capillaries, based on infrared light absorption of oxygenated and deoxygenated hemoglobin. 11 Pulse oximetry has been used for determining arterial insufficiency in patients suffering from venous leg ulcers (VLU) and those at high risk for diabetic ulcers. 12 While pulse oximetry can help detect early signs of ulcers and regionalize areas with poor healing, irregular movement of the patient or failure to accommodate measurements in cases of low hemoglobin contributes to its inaccuracies.…”

Significance: Chronic wounds affect millions of patients worldwide, placing a huge burden on health care resources. Although significant progress has been made in the development of wound treatments, very few advances have been made in wound diagnosis. Recent Advances: Standard imaging methods like computed tomography, single-photon emission computed tomography, magnetic resonance imaging, terahertz imaging, and ultrasound imaging have been widely employed in wound diagnostics. A number of noninvasive optical imaging modalities like optical coherence tomography, near-infrared spectroscopy, laser Doppler imaging, spatial frequency domain imaging, digital camera imaging, and thermal and fluorescence imaging have emerged over the years. Critical Issues: While standard diagnostic wound imaging modalities provide valuable information, they cannot account for dynamic changes in the wound environment. In addition, they lack the capability to predict the healing outcome. Thus, there remains a pressing need for more efficient methods that can not only indicate the current state of the wound but also help determine whether the wound is on track to heal normally. Future Directions: Many imaging probes have been fabricated and shown to provide real-time assessment of tissue microenvironment and inflammatory responses in vivo. These probes have been demonstrated to noninvasively detect various changes in the wound environment, which include tissue pH, reactive oxygen species, fibrin deposition, matrix metalloproteinase production, and macrophage accumulation. This review summarizes the creation of these probes and their potential implications in wound monitoring.

“…8 In Engeland gebruiken huisartsen hun pulsoximeter het vaakst bij COPD-patiënten die zich presenteren met een exacerbatie. 9 In dat onderzoek rapporteerden de betrokken huisartsen dat de pulsoximetrie hun beslissing had beïnvloed bij 20% van de exacerbaties. In Nederland heeft de SpO 2 -bepaling inmiddels een plaats gekregen in de landelijke richtlijnen voor COPD.…”
