Dyspnea in the ICU: It Is Difficult to See What Patients Feel

Dyspnea, or breathing discomfort, poses challenges for mechanically ventilated patients unable to communicate. Researchers propose the Mechanical Ventilation–Respiratory Distress Observation Scale (MV-RDOS) to assess distress using clinical signs. Although it correlates with patient-reported dyspnea, caution is advised when interpreting scores. MV-RDOS can guide interventions like ventilator adjustments and morphine administration. A threshold of 3.5 suggests when palliative treatment should be considered. Balancing relief and risks, and optimizing MV-RDOS's utility across ICU settings requires more research. Nonetheless, it offers a promising step toward addressing dyspnea in noncommunicative ventilated patients.
