‘Lung Ventilation: Natural and Mechanical’ describes the processes of respiration and lung ventilation, focusing on those issues related directly to mechanical ventilation. The chapter starts by discussing the anatomy and physiology of respiration, and the involvement of the lungs and the entire respiratory system. It continues by introducing the three operating principles of mechanical ventilation. It then narrows its focus to intermittent positive pressure ventilation (IPPV), the operating principle of most modern critical care ventilators, explaining the pneumatic process of IPPV. The chapter ends by comparing natural and mechanical/artificial lung ventilation.

Abstract Background Nursing students struggle with anatomy and physiology course because of the complicated terminology and the difficulty in handling large amounts of information. New, innovative instructional strategies must be integrated into nursing education to improve nursing students’ performance in this challenging bioscience course. The aim of this study was to determine the impact of an innovative teaching strategy, the flipped classroom, on the performance and satisfaction of Omani nursing students in an anatomy and physiology course. Methods A quasi-experimental design was used with two classes of 112 first-year nursing students at the College of Nursing, Sultan Qaboos University, Oman. Online videos and active-learning activities about the respiratory system were developed and implemented in an anatomy and physiology course with 53 first-semester nursing students. The control group consisted of a previous cohort of 59 students enrolled in the same course but taught with a traditional lecture approach. The impact of the flipped classroom strategy was measured by students’ performance on the final examination and students’ self-reported satisfaction. Wilcoxon signed-rank and Mann-Whitney U tests were used to compare students’ academic performance. Results Our results showed that the performance of the flipped classroom group was better than that of the traditional lecture group. The mean scores of students instructed with the flipped classroom method on the respiratory system items in the final examination were significantly higher than those of the control group, U = 1089.00, z = − 2.789, p < .005. Moreover, the results of a survey showed that nursing students were satisfied with the flipped classroom method. Overall, 68 to 78% of students agreed or strongly agreed that the flipped classroom method improved their learning and increased their interest in the course. Conclusion Compared with the didactic lecture format, flipped classroom strategy improved Omani nursing students’ performance in and satisfaction with an anatomy and physiology course. These results show that the flipped classroom is an important teaching strategy in nursing education.
