What is the normal airway resistance range for an intubated patient?

The correct range for normal airway resistance in an intubated patient falls within 0.6 - 2.4 cmH2O. This range is considered typical for patients who are intubated because it reflects the resistance encountered by airflow through the artificial airway, which can be affected by factors such as tube size, length, and any presence of secretions or obstruction.

In clinical practice, maintaining within this resistance range is crucial for adequate ventilation and oxygenation. If resistance rises above this range, it might indicate issues such as kinking or obstruction of the endotracheal tube, increased secretions, or bronchospasm, all of which could potentially compromise the patient’s airway management.

Understanding this range allows healthcare providers to monitor and manage ventilation more effectively in mechanically ventilated patients, ensuring that airway resistance stays within normal limits for optimal respiratory function.
