12 Hemodynamic Management of LCOS
Second Step : CVP / Scv O2 Myocardial and/ or Vascular Dysfunction

13 Insert CVP/ScvO2 CVP low CVP high CVP N or low Sepsis? ScvO2 >70%
SvO2 <70% CVP N or low CVP high CVP low Consider global/right ventricular failure Hypovolaemic/ Haemorrhagic/ cause? Sepsis? Repeat Fluid challenge 250ml/ 5mins Echocardiography that preceeds cardiac output monitoring Repeat fluid challenge (250ml/5mins) or transfusion if necessary. Continue until normal values obtained Haemodynamic improvement Yes Continue until normal values obtained Haemodynamic improvement ? No response No Vasopressors Echocardiography that preceeds CO monitoring

Mempertahankan tekanan arteri rata2 (MAP) berkisar 65 – 90 mmHg dengan menggunakan obat vasoaktif. Mempertahankan saturasi vena sentral sekitar 70% dengan memberikan transfusi atau obat inotropik. < 70% PRBC to Hct 30 % < 70% > 70% GOAL INOTROPE(S)

17 Hemodynamic Management of LCOS Third Step: Echocardiography

18 Mebazaa et al. Intensive Care Med, 2004;30:185-96
Echocardiography Global heart failure Predominent left ventricular failure Predominent right ventricular failure TAMPONADE ? Massive mitral regurgitation ? Yes No LV dysfunction No Echocardiographic guided pericardiocentesis or surgical intervention PA catheter Pulmonary hypertension? Pulmonary vasodilators RV ischaemia? Reduce RV afterload, avoid excess volume, use inotropes if CO low Any CO Monitoring, ideally non invasive Optimise LV pre- and afterload, Inotropes if required Mebazaa et al. Intensive Care Med, 2004;30:185-96

19 Hemodynamic Management of LCOS Fourth Step: Pulmonary Artery Catheter

22 Pemantauan Kardiovaskuler
Fungsi utama sistem Kardiovaskuler: menjamin kecukupan pasokan dan kebutuhan sel-sel tubuh akan O2 dan membawa sisa metabolisme untuk diekskresikan. CO (cardiac output) = SV (stroke volume) x HR (heart rate) MAP (mean arterial pressure) = (Sistolik + 2x Diastolik)/ 3 Atau MAP= Diast+ (Sist-Diast)/3 Besar MAP orang dewasa normal : mmHg. PP ( pulse pressure) adalah selisih antara tekanan sistolik dan diastolik. PP = Sist- Diast, atau PP= 3x ( MAP-Diast)

23 Saturasi Oksigen dan Oksigenasi Jaringan ( SaO2 dan DO2)
Delivery Oxygen (DO2) adalah jumlah oksigen yang harus tersedia bagi jaringan tubuh per menit. DO2 = CO x CaO2 ( oxygen content) CaO2= (1,34 x Hb x SaO2) + (0,0031x PaO2) DO2 = CO x (( 1,34 x Hb x SaO2) + ( 0,0031 x PaO2)) DO2 = delivery oxygen CO = cardiac output CaO2 = arterial oxygen content PaO2 = tekanan parsial oksigen di dalam darah arteri

36 Why SvO2? 22

37 Transport Oksigen

38 Transport Oksigen vena arteri CO CO tetap Hb Hb tetap SaO2 SvO2
Konsumsi Tetap tetap Hb Hb tetap SaO2 SvO2 berubah Konsumsi O2 = CO x Hb x (SaO2 - SvO2) x 1.34

39 Pada umumnya penurunan SvO2 merupakan indikator dini adanya gangguan oksigenasi jaringan

40 Berapa harga normal SvO2?
Harga normal SvO2 adalah % Nilai < 50% sudah mengkhawatirkan Nilai<30% menunjukkan adanya metabolisme anaerobik Lebih berguna mengikuti trend (sebagai respons terhadap perubahan terapi) dibanding hanya melihat nilai pada satu satuan waktu
