Abstract:
Carbon monoxide (CO) intoxication is one of the most common types of poisoning. Cardiac manifestations of CO poisoning are limited to case reports of Electrocardiogram (ECG) changes, myocardial dysfunction and myocardial ischemia. A 22 year old Saudi male was admitted to the emergency department with decreased level of consciousness after being involved in a fire at home. ECG showed first degree AV block. To the best of our knowledge, this case report is the first CO poisoning case in the literature presented with first degree AV block.

Hypoxia
Types of Hypoxia
There are four primary types of hypoxia, each resulting from a different cause:
1. Anemic hypoxia: This type occurs due to insufficient oxygen delivery caused by a lack of red blood cells (RBCs) or RBCs with abnormal or...
Acute Respiratory Failure-I
Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...
Acute Respiratory Failure-II
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:
Pneumothorax-I
Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.
