68W EMT Module 2 Respiratory Emergencies and Airway Management 2026 Study Guide | 120+ EMT Exam Questions and Answers on Airway Adjuncts, Oxygen Therapy, Ventilation, Respiratory Anatomy & Emergency Airway Care | Army 68W Combat Medic

This 68W EMT Module 2 Respiratory Emergencies and Airway Management 2026 Study Guide contains more than 120 comprehensive EMT and Combat Medic exam questions with verified answers covering respiratory anatomy and physiology, airway management, oxygen administration, artificial ventilation, respiratory emergencies, suctioning procedures, airway adjuncts, gas exchange, oxygen delivery devices, and emergency airway assessment. The document provides detailed review material on upper and lower respiratory anatomy, hypoxia, hypercapnia, respiratory distress, respiratory failure, respiratory arrest, oxygen therapy equipment, airway obstruction recognition, and ventilation techniques commonly tested in Army 68W Combat Medic training, EMT certification programs, and emergency medical services coursework. The study guide is organized in a structured question-and-answer format specifically designed to strengthen airway management knowledge, respiratory assessment competency, oxygen administration skills, emergency care understanding, and certification exam preparation. Students and emergency medical professionals will review major concepts including the anatomy of the upper and lower respiratory systems, alveolar ventilation, tidal volume, minute volume, dead space ventilation, diffusion, pulmonary respiration, cellular respiration, and chemoreceptor function. The material also explores airway assessment findings such as stridor, hoarseness, gurgling, cyanosis, hypoxia, inadequate breathing patterns, and respiratory compromise while reinforcing appropriate intervention strategies in emergency medical settings. Major topics covered throughout the document include head-tilt chin-lift procedures, spinal injury airway precautions, oropharyngeal airways (OPA), nasopharyngeal airways (NPA), suctioning techniques, airway clearance, artificial ventilation methods, bag-valve-mask (BVM) ventilation, mouth-to-mask ventilation, oxygen cylinder safety, oxygen flow rates, oxygen delivery devices, tracheostomy care, gastric distention, carbon monoxide poisoning, and respiratory monitoring. The guide also reviews oxygen administration equipment such as nonrebreather masks, nasal cannulas, partial rebreather masks, and Venturi masks while explaining oxygen concentrations, ventilation rates for adults, children, and infants, and the recognition of respiratory distress and respiratory failure. Additional sections focus on respiratory physiology and emergency airway care concepts including alveolar gas exchange, oxygen transport, carbon dioxide elimination, artificial ventilation complications, oxygen toxicity considerations, airway suction equipment requirements, oxygen cylinder capacities, airway obstruction management, advanced airway complications, and patient positioning strategies during ventilation. The material reinforces foundational emergency medical principles essential for EMTs, combat medics, first responders, and prehospital healthcare providers responsible for respiratory assessment and intervention. This resource is especially valuable for Army 68W Combat Medic candidates, EMT students, Advanced EMT students, paramedic students, military medical personnel, emergency medical responders, healthcare trainees, nursing students, and individuals preparing for military medical training programs or emergency medical certification examinations. It is highly suitable for NREMT preparation, Army 68W coursework, EMT classroom review, airway management training, respiratory emergency education, and independent medical study. The respiratory anatomy, airway management, and emergency medical concepts discussed throughout this review align with widely recognized emergency medicine and EMS educational literature, including: Emergency Care and Transportation of the Sick and Injured by the American Academy of Orthopaedic Surgeons (AAOS) Nancy Caroline’s Emergency Care in the Streets by Nancy Caroline Prehospital Emergency Care by Joseph J. Mistovich and Keith J. Karren Combat Medic Specialist Training Program (68W) Curriculum by the U.S. Army Medical Center of Excellence Core topics such as airway management, oxygen therapy, respiratory physiology, ventilation techniques, respiratory emergencies, suctioning procedures, patient assessment, and prehospital emergency care are also supported by standards and educational guidance published by NREMT, NAEMT, AHA, American Red Cross, and the U.S. Army Medical Department.
