Perbandingan nilai faal paru penyelam satkopaska di dalam ruang hiperbarik bertekanan 1,5 ata antara yang menghirup oksigen 100% dengan udara biasa = Lung function comparison of satkopaska divers between breathing 100% oxygen and air in 1.5 ata at hyperbaric chamber.

Latar Belakang Penyelaman adalah kegiatan yang dilakukan pada tekanan lebih dari 1 atmosfer absolut (ATA) baik di dalam air maupun dalam ruang hiperbarik yang mempengaruhi struktur dan fungsi tubuh. Tujuan penelitan ini membandingkan nilai faal paru penyelam terlatih di dalam ruang hiperbarik bertekanan 1,5 ATA antara yang menghirup oksigen 100% dengan udara biasa. Metode Penelitian ini merupakan uji eksperimental dengan desain crossover pada 18 penyelam militer di dalam ruang hiperbarik bertekanan 1,5 ATA setara dengan kedalaman 5 meter. Delapan belas subjek sebagai kelompok perlakuan menggunakan masker oronasal menghirup oksigen 100% selama 30 menit dengan periode wash out 1 hari, lalu dilakukan crossover menjadi kelompok kontrol menghirup udara biasa selama 30 menit. Pemeriksaan faal paru dilakukan sebelum dan sesudah perlakuan. Hasil Delapan belas subjek yang menghirup oksigen 100% terjadi peningkatan KV sebesar 1,82% (p>0,05), penurunan KVP sebesar 0,2% (p>0,05), VEP 1 sebesar 5,2% (p0,05), VEP 1 sebesar 1,7% (p>0,05) dan penurunan VEP 1 /KVP sebesar 1,7% (p0,05). Terdapat hubungan antara umur dan lama penyelaman terhadap nilai faal paru kedua kelompok. Kesimpulan Terdapat perbedaan bermakna nilai faal paru penyelam militer di dalam ruang hiperbarik bertekanan 1,5 ATA yang menghirup oksigen 100% dan udara biasa selama 30 menit. Penggunaan oksigen 100% dengan udara biasa pada tekanan 1,5 ATA tidak berbeda secara bermakna. Nilai faal paru sesudah perlakuan dengan periode wash out 1 hari dapat kembali seperti semula.

Introduction Diving is an activity conducted at a pressure of more than 1 absolute atmosphere either under water or in a hyperbaric chamber which affect the structure and the function of the body. The objectives of this study was to compare the lung function value of skilled divers in a hyperbaric chamber pressurized of 1.5 ATA between divers breathing 100% oxygen and air. Method This study was an experimental study using a crossover design. The subject of this study was 18 militery divers in a hyperbaric chamber pressurized of 1.5 ATA which was equivalent to a depth of 5 meters. Eighteen subjects as the treatment group was breathing 100% oxygen for 30 minutes using the oronasal mask. The subjects then underwent 1 day wash out period, then was changed to be the control group which breathing room air for 30 minutes. Examination of lung function was done before and after the experiment. Result Eighteen subjects in the treatment group whom breathing 100% oxygen experienced an increase of vital capacity (VC) by 1.82% (p>0.05), a decrease of forced vital capacity (FVC) by 0.2% (p>0.05), a decrease of forced expiratory volume during the first second (FEV 1 ) by 5.2% (p0.05), a decreased of FEV 1 by 1.7% (p>0.05) and a decrease of FEV 1 /FVC by 1.7% (p0.05). There was a significant relationship between age and diving duration on the value of lung function in both groups. Conclusion There was significant differences in lung function values of militery divers in a hyperbaric chamber pressurized of 1.5 ATA whom was breathing 100% oxygen and breathing air for 30 minutes in this study. The use of 100% oxygen with air at a pressure of 1.5 ATA was not significantly different. The value of lung function after 1 day wash out period was physiologically reversible.
