  1. FISIOLOGIA RESPIRATORIA II DRA: CAROLINA DELGADILLO R2A COORDINADOR: DR. JESUS ALARCON HOSPITAL ANGELES DEL PEDREGAL

  2. RELACION VENTILACION PERFUSION • VENTILACION MINUTO=FR X VOLUMEN CORRIENTE . • ADULTO NORMAL 5 L/MIN • VOLUMEN ALVEOLAR= FR X VT – VD • VD=150 ML (2 ML/KG)

  3. DISTRIBUCION DE LA VENTILACION • PULMON DERECHO:53 % • PULMON IZQ: 47 % • AREAS DECLIVES MEJOR VENTILADAS • LA PRESION PLEURAL SE REDUCE CERCA DE 1 CM H2O.

  4. DISTRIBUCION DE LA VENTILACION

  5. PERFUSION PULMONAR • 70 A 100 ML ESTAN EN EL INTERIOR DE LOS CAPILARES • 50- 100 M2 DE SANGRE. • POSICION DECUBITO A ERECTO DISMINUYE 27 % • HIPOXIA ----- VASOCONSTRICCION

  6. DISTRIBUCION DE PERFUSION PULMONAR

  7. RELA CION VENTILACION PERFUSION

  8. RELACION VENTILACION PERFUSION • V/Q =0.8 • CORTOCIRCUITO INTRAPULMONAR • ESPACIO MUERTO • “EFICACIACON LA CUAL LAS UNIDADES PULMONARES RESTAURAN SANGRE VENOSA CON O2 Y ELIMINAN CO2

  9. CORTOCIRCUITO O SHUNT PULMONAR

  10. CORTOCIRCUITO ANATOMICO

  11. VENTILACION PERFUSION

  12. RELACION V/Q
