Summary
Several tools evaluate pressure ulcer healing, including the Pressure Sore Status Tool (PSST) and Pressure Ulcer Scale for Healing (PUSH Tool). Further validation is needed for most instruments to ensure clinical and research reliability.
Area of Science:
- Wound Care
- Clinical Assessment Tools
- Pressure Ulcer Management
Background:
- Multiple instruments exist to document pressure ulcer status and healing.
- Common tools include the Pressure Sore Status Tool (PSST), Pressure Ulcer Scale for Healing (PUSH Tool), Sussman Wound Healing Tool (SWHT), Sessing scale, and Wound Healing Scale (WHS).
Purpose of the Study:
- To critically appraise the literature on pressure ulcer evaluation tools.
- To examine the development, validation, practicality, and future research needs of these instruments.
Main Methods:
- Literature review and critical appraisal of existing evaluation tools for pressure ulcers.
- Analysis of instrument development, validation status, and practical application.
Main Results:
- The PSST and Sessing scale have undergone more validation than the PUSH Tool, SWHT, and WHS.
- Most tools take approximately 5 minutes to complete, with the PSST taking 10-15 minutes.
- All tools require wound care experience and training for reliable use.
Conclusions:
- Further validation is necessary for all instruments to ensure suitability for clinical and research use.
- The PSST and Sessing scale are more validated currently compared to other tools.
- Training and experience are crucial for enhancing the reliability of these pressure ulcer assessment tools.

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

01:28Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies
Peptic ulcer disease (PUD) presents with diverse symptoms depending on the location and severity of the ulcer. Clinical manifestations of peptic ulcer include dull pain and a burning sensation in the mid-epigastric region.
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.

01:27Peptic Ulcer
Peptic ulcers are erosive lesions of the gastric or duodenal lining, most commonly caused by Helicobacter pylori infection. This Gram-negative, helical bacterium has adapted to survive the stomach’s acidic environment by producing urease, which converts urea into ammonia and carbon dioxide. The ammonia neutralizes gastric acid in the bacterium’s immediate environment, allowing colonization of the gastric mucosa. H. pylori attaches to mucus-secreting epithelial cells, penetrates the mucus...
01:25Peptic Ulcer Disease III: Clinical Manifestations and Complications
Duodenal UlcersDuodenal ulcers are the most common form of peptic ulcer disease, presenting with chronic, intermittent epigastric pain. Pain typically appears 2–3 hours after meals, especially when the stomach is empty, often waking patients at night. It is characteristically relieved by food or antacids (“pain–food–relief”). Some patients remain asymptomatic until complications like bleeding or perforation emerge, particularly with NSAID or anticoagulant use.Gastric UlcersGastric ulcers share...
