Abstract:
We herein report two cases with carbon monoxide- (CO-) induced delayed neuropsychiatric sequelae (DNS) successfully treated with hyperbaric oxygen therapy (HBOT) in attempt suicide by charcoal burning. The two patients with CO-induced DNS were successfully treated with a total of more than 100 sessions of HBOT. Frontal assessment battery (FAB) was useful to examine the effectiveness of HBOT objectively. In the future study, a large-randomized trial is required to establish the efficacy of HBOT for the treatment of DNS.

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...

Oxygen therapy is vital in increasing and maintaining blood oxygen levels in PAH patients. As a result, it aids in reducing fatigue,...
Acute Respiratory Failure-III
Physiological Control of Respiration
Breathing, a seemingly passive process, is regulated by the respiratory center in the brainstem. This center coordinates the involuntary control of respirations, which means it occurs without conscious effort, ensuring a smooth and uninterrupted pattern.
Regulation of Ventilation
The body maintains ventilation by monitoring levels of carbon dioxide (CO2), oxygen (O2), and hydrogen ion concentration (pH) in the arterial blood. Among these factors, the level of CO2 plays a crucial...
Acute Respiratory Failure-II
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:
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,...
