IMPLEMENTASI NEGATIVE PRESSURE HOOD (NPH) DAN NEGATIVE PRESSURE WHEELCHAIR (NPW) UNTUK MENCEGAH PENULARAN COVID-19 PADA PARA TENAGA KESEHATAN DI RS KEBON JATI

COVID-19, HEPA Filter, Negative Pressure Hood (NPH), Negative Pressure Wheelchair (NPW).Abstract
Rumah Sakit Umum Kebon Jati merupakan salah satu rumah sakit rujukan Covid-19 yang ada di Kota Bandung. Saat ini, proses transportasi pasien Covid-19 dilakukan dengan menggunakan ranjang dan kursi roda yang ditutupi dengan tudung mika transparan untuk mencegah penularan dari pasien ke lingkungan sekitarnya, tanpa dilengkapi alat filtrasi apapun. Rancangan tudung ranjang yang telah ada di RS membuat pasien kurang nyaman karena kondisi ventilasi dalam tudung kurang baik, Selain itu, rancangan tudung kursi roda yang tidak dilengkapi sistem negative pressure membuat tenaga kesehatan merasa khawatir jika udara infeksius dalam tudung menyebar tidak terkontrol. Hal ini menjadi perhatian dan motivasi tim untuk memodifikasi ranjang dan alat transfer pasien yang sudah ada dengan menggunakan sistem negative pressure yang dilengkapi HEPA filter. Modifikasi tersebut dilakukan untuk mencegah udara yang dihembuskan pasien keluar dari tudung (hood) tanpa terkendali dan tanpa filtrasi.. Berdasarkan hasil survei yang telah dilakukan, penggunaan Negative Pressure Hood (NPH) dan Negative Pressure Wheelchair (NPW) dapat meningkatkan kenyamanan dan mengurangi kekhawatiran tenaga kesehatan atas penularan virus. Hasil eksperimen pada simulasi kondisi ruangan dan menggunakan smoke generator sebagai simulator partikel virus, menunjukkan nilai efisiensi filtrasi lebih dari 90% dengan tingkat desibelmeter blower sekitar 55-68 dB untuk NPH dan NPW.
