Which of the following represents the categories of ARDS severity?

The classification of ARDS severity is based on the Berlin Definition, which categorizes the condition into three specific groups: Mild, Moderate, and Severe. This classification is established based on the degree of hypoxemia, as indicated by the PaO2/FiO2 ratio (the ratio of arterial oxygen partial pressure to fractional inspired oxygen). Understanding these categories is important for determining the appropriate management and treatment strategies for patients with ARDS.

Mild ARDS is characterized by a PaO2/FiO2 ratio of 200 to 300 mmHg, Moderate ARDS ranges from 100 to 200 mmHg, and Severe ARDS indicates a ratio of less than 100 mmHg. This clear stratification allows healthcare providers to assess the severity of the patient's respiratory compromise and adapt their approach accordingly.

In contrast, other suggested categories such as Light, Average, Severe or Beginner, Intermediate, Advanced do not align with the established medical framework and terminology related to ARDS. These terms do not accurately reflect the clinical parameters and may lead to confusion when assessing patient conditions and needs in critical care settings. Thus, Mild, Moderate, and Severe is essential for accurate diagnosis and treatment planning.
