EtCO₂ Nedir?

EtCO₂ (End-Tidal Carbon Dioxide), ekshalasyon sonunda solunum havasındaki karbondioksit konsantrasyonunun ölçümüdür. Genellikle milimetre cıva (mmHg) birimiyle ifade edilir ve kapnografi cihazı kullanılarak ölçülür. EtCO₂, solunum sistemi, kardiyak dolaşım ve metabolizma hakkında önemli bilgiler sağlar. Solunum döngüsünün sonunda, ekshalasyon sırasında solunum yollarından çıkan gazdaki en yüksek karbondioksit (CO₂) konsantrasyonunu ifade eder. Bu değer, takibinin temelini oluşturur. Solunum sistemi, dolaşım ve metabolizma arasındaki bağlantıyı yansıtarak hastanın genel durumunu değerlendirir.

Normal EtCO₂ Değerleri

Normal EtCO₂ seviyesi genellikle 35-45 mmHg arasındadır.

  • Düşük EtCO₂: Hiperventilasyon, düşük kardiyak output veya pulmoner emboli gibi durumları işaret edebilir.
  • Yüksek EtCO₂: Hipoventilasyon, aşırı metabolik aktivite veya ventilatör ayarlarının yetersiz olduğunu gösterebilir.

Mekanik ventilatörlerle EtCO₂ seviyelerinin izlenmesi, hastanın solunum durumu ve ventilasyon etkinliğinin değerlendirilmesinde kritik bir rol oynar. Bu izleme, kapnografi cihazları aracılığıyla gerçekleştirilir ve genellikle ventilatör sistemine entegre edilir.

EtCO₂ İzleme Yöntemleri

  1. Ana Akım Kapnografi:
    • Nasıl Çalışır: Sensör, endotrakeal tüp veya trakeostomi tüpü ile solunum devresi arasına yerleştirilir. Hastanın ekshalasyon havası doğrudan sensörden geçer ve CO₂ konsantrasyonu anında ölçülür.
    • Avantajları: Anlık ve doğru ölçümler sağlar; ekshalasyon sırasında gecikme minimaldir.
    • Dezavantajları: Sensörün ağırlığı ve ısınması, özellikle küçük çocuklar veya zayıf hastalar için rahatsızlık yaratabilir.
  2. Yan Akım Kapnografi:
    • Nasıl Çalışır: Solunum devresinden küçük bir gaz örneği alınarak cihazın analizörüne iletilir. Bu yöntem, entübe olmayan hastalarda da kullanılabilir.
    • Avantajları: Çeşitli solunum devreleriyle uyumludur ve entübasyon gerektirmeyen hastalarda da kullanılabilir.
    • Dezavantajları: Örnekleme hattında kondensasyon birikimi olabilir ve bu da ölçüm doğruluğunu etkileyebilir.

EtCO₂ Takibi ile Ventilasyon Verimliliği

EtCO₂ takibi, ventilasyon verimliliğini doğrudan değerlendiren bir yöntemdir. Solunum sisteminin karbondioksiti (CO₂) nasıl elimine ettiğini ve metabolik süreçler sonucunda oluşan CO₂’nin ventilasyon yoluyla dışarı atılma etkinliğini gösterir. Ventilasyon verimliliği, EtCO₂ seviyeleri ve kapnogram analizleri kullanılarak çeşitli klinik durumlarda değerlendirilir.

  1. Hipoventilasyon (Azalmış Ventilasyon):
    • EtCO₂ Seviyesi: Artar (genelde > 45 mmHg).
    • Sebep: Akciğerlerden CO₂ atılımının yetersiz olması.
    • Klinik Durumlar: Solunum depresyonu, sedasyon, nöromüsküler blokaj, obezite hipoventilasyon sendromu.
    • Etkisi: Yüksek EtCO₂ seviyeleri, ventilasyonun artırılması gerektiğini işaret eder.
  2. Hiperventilasyon (Artmış Ventilasyon):
    • EtCO₂ Seviyesi: Düşer (genelde < 35 mmHg).
    • Sebep: CO₂’nin aşırı elimine edilmesi.
    • Klinik Durumlar: Anksiyete, ağrı, hipoksiye yanıt, kompansatuvar mekanizmalar.
    • Etkisi: Ventilasyon hızının veya tidal volümün düşürülmesi gerekebilir.
  3. Alveolar Ölü Boşluk Artışı:
    • EtCO₂ Seviyesi: Düşer, ancak arteriyel CO₂ (PaCO₂) yüksektir.
    • Sebep: Akciğer perfüzyonunda azalma veya ventilasyon-perfüzyon (V/Q) uyumsuzluğu.
    • Klinik Durumlar: Pulmoner emboli, düşük kardiyak output, şok.
    • Etkisi: EtCO₂ seviyesi ile PaCO₂ arasındaki fark artar (EtCO₂-PaCO₂ gradyanı).
  4. Dolaşım Yetersizliği:
    • EtCO₂ Seviyesi: Düşer.
    • Sebep: Kardiyak output azaldığında, alveollere gelen CO₂ miktarı azalır.
    • Klinik Durumlar: Kardiyak arrest, düşük perfüzyonlu şok.
    • Etkisi: CPR’nin etkinliğini izlemek için kullanılır; EtCO₂’nin artışı dolaşımın yeniden sağlandığını gösterebilir.

Sık Sorulan Sorular

1)Normal EtCO₂ değeri nedir?

35-45 mmHg arasındadır.

2)Düşük EtCO₂ ne anlama gelir?

Ekshalasyon havasındaki karbondioksit seviyesinin normalden düşük olduğu bir durumu ifade eder. Bu durum, ventilasyon, perfüzyon veya metabolizma ile ilgili sorunların bir göstergesi olabilir. Genelde 35 mmHg’nin altındaki EtCO₂ seviyeleri, hipokapni olarak adlandırılır.
