Hypoxaemia: Reversible Causes of Cardiac Arrest

CPDTime.
6m of CPD
Hypoxaemia is the reduction in oxygen partial pressure values dissolved in arterial blood (PaO2) and arterial oxygen saturation (SaO2) (Pruitt, 2004). Pa02 is best measured by arterial blood gas (ABG) analysis, while SaO2 can be routinely assessed using a non-invasive test called pulse oximetry.

What is this article about?

<p>Reversible Causes of Cardiac Arrest - 4Hs and 4Ts: Hypoxaemia This is the first explainer in a series of eight, outlining reversible causes of cardiac arrest. What is Hypoxaemia? Hypoxaemia is the reduction in the values for partial pressure of oxygen dissolved in arterial blood (PaO2) and arterial oxygen saturation (SaO2) (Pruitt, 2004). Pa02 is best measured by arterial blood gas (ABG) analysis, while SaO2 can be routinely assessed using a non-invasive test called pulse oximetry. During nursing assessment, hypoxaemia should be considered if a patient has a respiratory rate greater than 24 per minute, and arterial oxygen saturations (SaO2) </p>

The algorithm notes that the reversible causes of arrest typically result in a non- shockable rhythm, Performing CPR takes precedence over treating the reversible causes within the first two minutes. The reversible causes of cardiac arrest can classified into two categories which are the H's and T's. They are : Hypoxia- is life threatening when the lungs do not function or provide enough oxygen to maintain perfusion to the tissues. That will lead to stress, lactic acid build up all over the body thus causing tissue death and the loss of electrical activity.To treat HYPOXIA,establish an advanced airway,rescue breaths, CPR and oxygen therapy. Hypovolemia- loss of bodily fluid typically blood,traumatic blood loss,gastrointestinal bleeding,severe diarrhoea,vomiting,ongoing dehydration and extreme sweating in the form of decrease blood flow. To treat ,administer plasma,IV fluids,blood and clotting factors( Savealife.com) Accessed 7/04/2020
