2 HC1 – BLOOD GASES

2.1 BLOOD GASES
= Blood sample to determine blood gases analysis (test)
- Arterial
- Venous

2.1.1 Venous blood gas(es)
- Peripheral venous sample
- Central venous sample
- Mixed venous sample

Peripheral venous sample
Zijn makkelijk uit te voeren door een venipuncture




Central venous sample
Central venous blood is venous bloed dat teruggaat naar de rechterkant van het hart in de vena cava
superior.




Mixed venous sample
Mixed venous bloed is venous bloed van de meest distale poort van de PA catheter, een mix van
inferior vena cava bloed, superior vena cava bloed, en de coronaire sinussen.
Het resultaat is een gemiddelde van venous bloed.

,Cardiorespiratory Physiotherapy 3 1e master jaar Revaki UA


Application venous blood samples
Peripheral venous blood sample → normale bloedtest, meeste bloedtests worden zo uitgevoerd.

Central venous – mixed venous blood sample → Central venous en mixed venous blood kan
genomen worden om zuurstofconsumptie te meten. Door central venous en mixed venous bloed te
nemen kunnen we de zuurstofopname en levering meten




2.1.2 Arterial blood gases : ABG
How to take an arterialblood sample
- Puncture van een arterie
- Meest gebruikte arteriele puncture plaatsen:
o Arteria radialis
o Arteria femoralis
o Arteria dorsalis pedis

Andere manier om af te nemen is door een indwelling catheter. Meeste hebben een arteriele
catheter. Machine zal alle bloedgassen analyseren en naar computer sturen.


2.1.3 Blood gas analysis
Een bloedgas analyse meet:
- PaO2 = Partieeldruk van zuurstof in bloed
- SaO2 = O2 saturatie
- PaCO2 = Partieel druk van CO2 in bloed
- pH = maat voor zuurgraad
- HCO3 = Waterstofcarbonaat

Normal blood gas values

, Cardiorespiratory Physiotherapy 3 1e master jaar Revaki UA


Pulse Oximetry (SaO2)
Meet de zuurstof saturatie, gemeten met een pulse oximeter.

Zie normaalwaardes arteriele bloedgassen
Normaal waardes op zee niveau en FiO2 = 20,96%.
BELANGRIJK: WAARDES KENNEN!

PaO2 = partiele druk O2 = 85-100 mmhg

SaO2 = saturatie = 95-100%

PaCO2 = partiele druk CO2 = 35-45 mmhg

pH = 7.36-7.45

HCO3 = 23-25 mmol/l




2.2 INTERPRETATION ARTERIAL BLOOD GASES
- Interpretatie PaCO2
- Interpretatie PaO2
- Respiratory insufficiency
- Acid-Base interpretatie

How do we come to this normal values of PaO2 en PaCO2?




- FiO2 = fraction van zuurstof in ingeademde lucht
- FiCO2 = fraction van koolstofdioxide in ingeademde lucht
- PiO2 = partiele druk van zuurstof in ingeademde lucht
- PiCO2 = partiele druk van koolstofdioxide in ingeademde lucht
