Tujuan: Melalui penelitian ini dapat diketahui retensi mengenai ketrampilan BHD pada mahasiswa Fakultas Kedokteran Universitas Airlangga. Metode: Penelitian ini merupakan penelitian deskriptif dengan pendekatan cross-sectional. Subjek merupakan mahasiswa Fakultas Kedokteran Universitas Airlangga yang telah menjalani pelatihan BHD dan lulus dalam ujian setelahnya. Lima puluh dua mahasiswa diminta untuk mempraktekkan kembali teknik pemberian BHD dan dinilai menggunakan daftar penilaian modifikasi dari penilaian ketrampilan BHD milik American Heart Association (AHA). Hasil: Persentase mahasiswa yang melakukan dengan benar, antara lain: periksa kesadaran-verbal
