Mechanical Ventilation Exam Questions (90 Q&A) – RESP 204, Ventilator Settings, Alarms, Weaning – Kettering

This document contains a structured set of approximately 90 exam-style questions and verified answers focused on mechanical ventilation in respiratory care. It covers fundamental ventilator concepts such as trigger and cycle variables, ventilator alarms (low pressure, high pressure, low exhaled tidal volume), and troubleshooting techniques for circuit leaks, obstructions, and equipment malfunctions. It also explains key monitoring parameters like mean airway pressure (mPaw), alveolar ventilation, and the relationship between compliance, resistance, and work of breathing. The material provides in-depth coverage of ventilator management strategies, including adjustments for abnormal PaCO₂ levels, optimization of oxygenation, and interpretation of ventilator waveforms and flow patterns. It also includes advanced topics such as high-frequency oscillatory ventilation (HFOV), ARDS management protocols (including ARDSnet guidelines), recruitment maneuvers, and prone positioning. As shown on page 1, the document introduces core ventilator variables and alarms, while later sections (pages 4–7) expand into weaning strategies, spontaneous breathing trials (SBT), and noninvasive ventilation (NIPPV). Additionally, the document emphasizes clinical decision-making in ventilator weaning, including criteria for readiness, appropriate duration of spontaneous breathing trials, and post-weaning evaluation using ABGs. It also discusses indications and contraindications for noninvasive ventilation (e.g., COPD and CHF vs ARDS), along with initial settings and patient management strategies. The content aligns closely with standard respiratory care textbooks such as Egan’s Fundamentals of Respiratory Care, making it a valuable resource for both theoretical understanding and clinical application. This document is ideal for students enrolled in courses such as RESP 204 (Mechanical Ventilation), Critical Care Respiratory Therapy, Advanced Ventilator Management, and Cardiopulmonary Care. It is also highly relevant for respiratory therapy students, ICU and emergency nursing students, paramedic trainees, and healthcare professionals preparing for certification exams such as the NBRC (CRT/RRT).
