Arterial Blood Gases Sample
Arterial blood gas analysis is an important laboratory test that contributes to diagnostic interventions. Arterial blood gas analysis can give information on the acid-base balance, oxygenation status, and ventilation status from the interpretation of parameters such as the partial pressures of oxygen and carbon dioxide, the pH, base deficit, and blood bicarbonate levels (Castro et al., 2022). The findings can accurately support the diagnosis of various circulatory, respiratory and metabolic disorders that are associated with an imbalance in the acid-base balance and impaired oxygenation and ventilation (Castro et al., 2022). Competency in the interpretation of blood gas analysis is thus a necessary skill among healthcare professionals.

Insomnia is a common complaint that sometimes necessitates the evaluation of arterial blood gases. Insomnia is usually characterized by difficulties initiating or maintaining sleep with resultant impaired daytime functioning, sleepiness, inattention, and exhaustion (Karna et al., 2022). These effects are associated with a consequently reduced quality of sleep, reduced quality of life, and reduced productivity among affected individuals. Insomnia can be acute, chronic, or recurrent depending on the underlying cause. Some of the predisposing associated conditions can cause abnormalities in the arterial blood gas analysis findings. These include respiratory disorders such as obstructive sleep apnea and chronic obstructive pulmonary disease that cause nocturnal hypoxemia.
Insomnia related to sleep hypoventilation can be detected through serial evaluations of arterial blood gases. Hypoventilation results in respiratory acidosis due to the retention of carbon dioxide and inadequate perfusion which is evidenced by the elevated partial pressure of carbon dioxide and diminished bicarbonate levels (Patel et al., 2022). This also causes acidity with a consequent drop in the blood pH. Individuals with obstructive sleep apnea for example frequently demonstrate daytime hypercapnia on evaluation (Pei et al., 2021). The findings from arterial blood gas analysis can also guide targeted treatment of insomniacs such as administration of oxygen therapy in the event of inadequate perfusion. Integration of information from the patient history and further supportive diagnostic evaluation will ensure accurate diagnosis and appropriate management.
