  1. TEKANAN DARAH DAN PENGATURANNYA Detty Iryani Bagian Fisiologi Fakultas Kedokteran UNAND

  2. Tekanan arteri : • Tekanan sistole (120 mmmHg) • Tekanan diastole (70 mmHg) • Tekanan nadi (Pulse pressure):TS-TD (50 mmHg) • Tekanan rata-rata (Mean arterial blood pressure=MABP)= TD+1/3(TS-TD) • MABP=COxR

  3. METODE PENGUKURAN TEKANAN DARAH • Secara langsung • Secara tidak langsung • palpasi • Auskultasi….. Bunyi Korotkoff (1-5)

  4. PENGATURAN TEKANAN DARAH • Pusat kardiovaskular di MO • Neuronal: reflex baroreseptor, reflex kemoreseptor • Hormonal: • RAA • Epinefrin dan NE • ADH • Atrial natriuretic Peptide (ANP) • Autoregulasi

  5. PENGATURAN JANGKA PENDEK TERHADAP PENURUNAN TD

  6. PENGATURAN JANGKA PENDEK TERHADAP PENINGKATAN TD

  7. Efek gravitasi terhadap tekanan darah (perubahan posisi) • Faktor lain yang mempengaruhi tekanan darah • Tekanan vena dan faktor yang mempengaruhi
