  1. ANALOGY PATIENT

  2. ANALOGY Daily metabolic challenges PATIENT Minute volume Diaphragm

  3. ANALOGY Daily metabolic challenges PATIENT Minute volume Diaphragm Accelerator – respiratory centre Acc. Cable – phrenic nerve Carburettor throttle opening – Edi Rusted accelerator cable – neurological problems

  4. ANALOGY Daily metabolic challenges Pathology (secretions) PATIENT Minute volume Diaphragm Accelerator – respiratory centre Acc. Cable – phrenic nerve Carburettor throttle opening – Edi Rusted accelerator cable – neurological problems If engine works with less than 4 cylinders – diaphragm pathology

  5. ANALOGY VENTILATOR ?

  6. ANALOGY VENTILATOR

  7. ANALOGY Daily metabolic challenges Ppeak Pathology VENTILATOR PATIENT Minute volume Diaphragm Accelerator – respiratory centre Acc. Cable – phrenic nerve Carburettor throttle opening – Edi Rusted accelerator cable – neurological problems If engine works with less than 4 cylinders – diaphragm pathology

  8. ANALOGY Conventional Ventilator triggers (pushes more) when patient ‘pulls’ Ventilator does not ‘see’ need for speed, and fast metabolic changes, rather estimates and maintains constant speed, as synchronious as possible. Daily metabolic challenges Ppeak Pathology VENTILATOR PATIENT Minute volume Diaphragm Accelerator – respiratory centre Acc. Cable – phrenic nerve Carburettor throttle opening – Edi Rusted accelerator cable – neurological problems If engine works with less than 4 cylinders – diaphragm pathology

  9. NAVA introduces link (Edi) between patient’s carburettor, and ‘push truck’s’ accelerator Daily metabolic challenges Ppeak Pathology VENTILATOR PATIENT Minute volume Diaphragm Accelerator – respiratory centre Acc. Cable – phrenic nerve Carburettor throttle opening – Edi Rusted accelerator cable – neurological problems If engine works with less than 4 cylinders – diaphragm pathology

  10. ANALOGY NAVA introduces link (Edi) between patient’s carburettor, and ‘push truck’s’ accelerator Edimax signal (= Peak Pressure), Tidal volume and Breath rate (= Minute volume) are controlled by the patient NAVA Level Daily metabolic challenges Ppeak Pathology VENTILATOR PATIENT Minute volume Diaphragm Accelerator – respiratory centre Acc. Cable – phrenic nerve Carburettor throttle opening – Edi Rusted accelerator cable – neurological problems If engine works with less than 4 cylinders – diaphragm pathology

  11. ANALOGY NAVA introduces link (Edi) between patient’s carburettor, and ‘push truck’s’ accelerator (Small) NAVA level increase or decrease usually results in instantaneous Edi signal ‘correction’ NAVA Level Daily metabolic challenges Ppeak Pathology VENTILATOR PATIENT Minute volume Diaphragm Accelerator – respiratory centre Acc. Cable – phrenic nerve Carburettor throttle opening – Edi Rusted accelerator cable – neurological problems If engine works with less than 4 cylinders – diaphragm pathology

  12. ANALOGY NAVA introduces link (Edi) between patient’s carburettor, and ‘push truck’s’ accelerator NAVA Level Healing (pathology clearing) will result in lower Edi Daily metabolic challenges Ppeak VENTILATOR PATIENT Minute volume Diaphragm Accelerator – respiratory centre Acc. Cable – phrenic nerve Carburettor throttle opening – Edi Rusted accelerator cable – neurological problems If engine works with less than 4 cylinders – diaphragm pathology

  13. ANALOGY NAVA introduces link (Edi) between patient’s carburettor, and ‘push truck’s’ accelerator (faster) Engine improvement (4 cylinders working) will result with lower Edi, AND lower Peak Pressure (more pull) NAVA Level Daily metabolic challenges Ppeak VENTILATOR PATIENT Minute volume Diaphragm Accelerator – respiratory centre Acc. Cable – phrenic nerve Carburettor throttle opening – Edi Rusted accelerator cable – neurological problems

  14. ANALOGY NAVA introduces link (Edi) between patient’s carburettor, and ‘push truck’s’ accelerator NAVA Level Daily metabolic challenges Ppeak Pathology VENTILATOR PATIENT Minute volume Diaphragm Accelerator – respiratory centre Acc. Cable – phrenic nerve Carburettor throttle opening – Edi Rusted accelerator cable – neurological problems If engine works with less than 4 cylinders – diaphragm pathology
