Clinical photograph of a patient in an intensive care unit (ICU) setting demonstrating the application of 'fan therapy' for dyspnea management. The patient is supine in a hospital bed, appearing sedated or with eyes closed, and is undergoing mechanical ventilation via an endotracheal tube secured with adhesive tape. In the foreground, a portable, battery-operated electric fan is positioned on an overbed tray table, directed toward the patient's face. This non-pharmacological intervention is designed to alleviate the sensation of breathlessness by providing cool airflow to the regions innervated by the second (maxillary) and third (mandibular) branches of the trigeminal nerve. The background shows standard critical care infrastructure, including medical gas outlets, electrical panels, and suction equipment. This image illustrates palliative and supportive care techniques used to manage respiratory distress in critically ill or end-of-life patients.

This medical infographic presents three clinical algorithms (A, B, and C) for managing massive bleeding in acute settings. Algorithm A details a ROTEM-guided approach for uncoagulated patients, using viscoelastic parameters (EXTEM, FIBTEM, APTEM) to differentiate and treat hyperfibrinolysis (tranexamic acid), hypofibrinogenemia (fibrinogen concentrate), thrombin deficiency (prothrombin complex), and thrombocytopenia. Algorithm B outlines management for uncoagulated patients when ROTEM is unavailable, focusing on monitoring for the 'lethal triad' (acidosis, hypothermia, coagulopathy), lab values like hemoglobin and base excess, and the administration of blood products or PCC. Algorithm C addresses oral anticoagulant overdose, branching by agent type: Vitamin K Antagonists (VKA) or Direct Oral Anticoagulants (DOACs). It provides decision nodes based on INR levels and hemorrhage severity, recommending reversal agents such as Vitamin K, prothrombin complex (PCC), or Idarucizumab for dabigatran. The diagrams use standardized medical terminology and dosage guidelines suitable for emergency medicine, hematology, and trauma surgery education.

Summary : This flowchart outlines a stepwise approach to the outpatient management of dyspnea, including routine screening, assessment, treatment of underlying causes, referral to palliative care, and both nonpharmacologic and pharmacologic interventions, with escalation to advanced measures as needed. flowchart: # Nodes : • Routine dyspnea screening in outpatient setting (every visit) (rectangle) • Further assessment (rectangle) • Stepwise management (rectangle) • Treatment of underlying cause(s) (rectangle) • Basic Measures (bold, underlined heading) – Acute complications (rectangle) – Cancer (rectangle) – Comorbidities (rectangle) • Specialist palliative care referral if available (rectangle) • Nonpharmacologic measures (rectangle) – In descending order of preference: (italicized) • Airflow or fan (rectangle) • Supplemental O₂ if hypoxemic (rectangle) • Self-management strategies (rectangle) • Breathing techniques (rectangle) • Breathing postures (rectangle) • Physical therapy (rectangle) • Acupressure or reflexology (rectangle) • Pharmacologic measures (rectangle) – In descending order of preference: (italicized) • Opioids (typically oral for everyday dyspnea or prophylaxis of exertional dyspnea) (rectangle) • Corticosteroids if structural causes (rectangle) • Bronchodilators if bronchospasm (rectangle) • Benzodiazepines if severe anxiety (rectangle) • Advanced Measures (bold, underlined heading) – High-flow oxygen at home, especially if severely hypoxemic (rectangle, highlighted) – Noninvasive ventilation at home, especially if hypercapneic (rectangle, highlighted) # Connectors : • Downward arrows connect each step in the main vertical sequence: screening → assessment → stepwise management → treatment of underlying causes → specialist palliative care referral → nonpharmacologic measures → pharmacologic measures. • From "Stepwise management," branches lead to "Basic Measures" (with sub-branches for acute complications, cancer, comorbidities). • From "Nonpharmacologic measures," a branch from "Supplemental O₂ if hypoxemic" leads to "High-flow oxygen at home, especially if severely hypoxemic" under Advanced Measures. • From "Nonpharmacologic measures," a branch from the same level leads to "Noninvasive ventilation at home, especially if hypercapneic" under Advanced Measures. # Layout : • The flowchart is organized vertically, with main steps in a single column. • "Basic Measures" and "Advanced Measures" are presented as parallel columns, with "Advanced Measures" highlighted in a different color. • Sub-steps under "Basic Measures," "Nonpharmacologic measures," and "Pharmacologic measures" are listed in descending order of preference. # Analysis : • The flowchart emphasizes a structured, stepwise approach to dyspnea management, starting with routine screening and progressing through assessment, treatment, and both nonpharmacologic and pharmacologic interventions. • Referral to specialist palliative care is recommended if available. • Nonpharmacologic measures are prioritized before pharmacologic ones, with specific interventions listed in order of preference. • Advanced measures such as high-flow oxygen and noninvasive ventilation are reserved for severe cases, particularly with hypoxemia or hypercapnia. • The chart visually distinguishes between basic and advanced interventions, highlighting escalation pathways for more severe symptoms.
