This Oxygenation Index (OI) Calculator is a vital tool for medical professionals, enabling the assessment of a patient's respiratory efficiency. By calculating the oxygenation index, healthcare providers can evaluate the severity of hypoxemia and guide treatment decisions.
All calculations are based on the standard formula for Oxygenation Index: OI = (FiO2 × Paw × 100) / PaO2. This method is widely used in clinical settings to assess the severity of a patient's condition.
The Oxygenation Index is calculated using the formula:
OI = \frac{FiO_2 \times Paw \times 100}{PaO_2}
For a patient with FiO2 of 40%, Paw of 10 cmH2O, and PaO2 of 80 mmHg, the OI is calculated as:
OI = \frac{40 \times 10 \times 100}{80} = 50
The Oxygenation Index is a calculated value used to assess the severity of hypoxemia in patients, guiding treatment decisions.
OI helps clinicians evaluate respiratory efficiency and the severity of lung injury, aiding in the management of ventilatory support.
OI should be calculated regularly in critically ill patients to monitor changes in respiratory function.
Normal OI values are typically less than 5. Higher values indicate more severe respiratory dysfunction.
OI is primarily used in critical care settings, particularly for patients receiving mechanical ventilation.
