  1. Actual amount of substance supplied (removed) A = Q x ( Ca – Cv)

  2. What determines flow (Q) Q = (Pa – Pv)/R

  3. Low vascular resistance Q High vascular resistance (vasoconstriction

  4. Measurement of Q

  5. Electromagnetic flowmeter

  6. Doppler effect

  7. Fick principle

  8. Blood flow velocity A= 2cm2 10cm2 1cm2 Q=10ml/s a b c V= 5cm/s 1cm/s 10cm/s V = Q / A

  9. Vascular wall flow

  10. murmur

  11. Laminar high flow turbulent laminar velocity

  12. Resistance to blood flow Rt = R1 + R2 + R3…………. Resistance in series 1/Rt = 1/R1 + 1/R2 + 1/R3…. Resistance in parallel R1 PARALLEL SERIES R2 R1 R2 R3 R3

  13. x x x x Redistribution in exercise

  14. Viskoaity ↑ při ↓↓ Q (anomalous blood viscosity)

  15. What determines R ? Wall tension vasokonstriction vasodilatation

  16. Laplace Pro trubici platí r

  17. Critical closing pressure Q pressure pressure Wall tension

  18. RECRUITMENT

  19. exercise

  20. Blood pressure Q = (Pa – Pv)/R

  21. systolic Blood pressure (torr) diastolic Mean velocity cm/sec

  22. Velocity of blood flow A= 2cm2 10cm2 1cm2 Q=10ml/s a b c V= 5cm/s 1cm/s 10cm/s V = Q / A

  23. SYSTOLIC SV elasticity of aorta DIASTOLIC R heart rate
