The use of non-invasive ventilation (NIV) and oxygen therapy has transformed the landscape of respiratory care, offering effective, less-invasive and relatively less-expensive solutions for patients with acute and chronic respiratory conditions. These modalities not only reduce the need for invasive procedures, but also improve patient outcome and quality of life. With advances in technology and a growing understanding of respiratory pathophysiology, the role of NIV and oxygen therapy continues to expand across various clinical settings.This manual serves as a comprehensive guide for healthcare professionals involved in respiratory and acute care medicine. It bridges the gap between theoretical knowledge and clinical practice, equipping readers with the tools to make informed decisions when managing patients requiring respiratory support.The book covers key concepts, including the evolution of NIV, its effects on respiratory physiology, indications and contraindications of NIV, device selection, troubleshooting, NIV in acute care and long-term chronic care, and the principles of oxygen therapy. Practical guidance is provided on monitoring and titrating therapy, ensuring patient comfort, and avoiding complications. Emphasis is placed on evidence-based practices, supported by current guidelines and case studies that highlight real-world applications.
