"Long-term oxygen therapy (LTOT) usually represents the final step in the management of severe chronic respiratory diseases. The focus of this volume is on new insights and novel perspectives of LTOT. Starting from consolidated experiences, it's aim is also to emphasize the strategic value of developing technologies and innovative organizational models uniquely to find out even more opportunities and advantages for the management of chronic respiratory patients needing long-term oxygen treatment."

"Penelitian ini membahas aktivitas spesifik katalase dalam mencegah stres oksidatif pada jaringan yang disebabkan oleh kondisi hipoksia hipobarik. Hipoksia hipobarik akut berulang sering dialami oleh para penerbang, terutama ketika harus menjalani prosedur Hypobaric Chamber training yang rutin diadakan dua tahun sekali. Salah satu jaringan yang rentan terhadap stres oksidatif akibat hipoksia adalah jaringan ginjal. Oleh karena itu, penelitian ini bertujuan untuk mengetahui perubahan aktivitas spesifik katalase jaringan ginjal tikus percobaan yang diinduksi hipoksia hipobarik akut yang berulang.Desain penelitian yang digunakan adalah desain eksperimental. Sampel jaringan ginjal diambil dari total 25 ekor tikus jantan galur Wistar yang dikelompokkan menjadi empat kelompok perlakuan dengan perbedaan frekuensi terhadap perlakuan prosedur Hypobaric chamber dan satu kelompok kontrol. Metode untuk mengukur aktivitas spesifik katalase menggunakan metode Mates et al. (1999) yang telah dimodifikasi oleh Departemen Biokimia dan Biologi Molekuler Fakultas kedokteran Universitas Indonesia.Hasil penelitian menunjukkan adanya peningkatan bermakna aktivitas spesifik katalase semua kelompok perlakuan dibandingkan dengan kelompok kontrol (p<0.05). Penelitian ini menyimpulkan bahwa terdapat perubahan berupa peningkatan yang signifikan aktivitas spesifik katalase di jaringan ginjal tikus percobaan yang diinduksi hipoksia hipobarik akut secara berulang dibandingkan dengan kelompok kontrol.

This research determines about specific activity of catalase in preventing hypoxiainduced oxidative stress. Besides, one of the most common hypoxia condition which occurs in aviators is hypobaric hypoxia. Hypobaric chamber training which has been a fundamental component of aviation training could induce acute intermittent hypobaric hypoxia. Kidney was known as highly-demand organ of oxygen which makes its susceptible to oxidative injury. This research aims to determine changes in specific activity of catalase in rat?s kidney exposed to acute intermittent hypobaric hypoxia.

The research design used was experimental design. Twenty five male Wistar rats were divided into five groups of five animals each. One control group of rats were kept under normobaric oxygen atmosphere. Four experimental group were exposed to acute hypobaric hypoxia in a hypobaric chamber for some intermittent period of time. Specific activity of catalase was determined using Modified Mates method.

The result shows that all experimental groups are significantly different in comparison with control group. This research concludes that there are significant increases in specific activity of catalase in all experimental groups compared to control group."

"Inadequate humidification of inspired gases can cause a variety of serious problems, and humidification has accordingly become an important aspect of modern intensive care medicine. This book is designed to serve as a practical guide for clinicians, providing information on the theoretical background of humidification, the equipment, and its optimal use. The book starts by examining the physiological basis of humidification. Current devices are then discussed, with careful attention to factors influencing their performance and methods to evaluate their effectiveness. The two scenarios of mechanical and non-mechanical ventilation are considered, and the issue of ventilator-associated pneumonia is addressed in detail. Further chapters focus on such topics as humidification following tracheostomy, humidification of the artificial airway during secretion management, measurement of inspired gas temperature in the ventilated neonate, and humidification in the home care setting."
