What are common signs indicative of respiratory failure?

Common signs indicative of respiratory failure include low oxygen saturation, inadequate breathing, and altered mental status.

Low oxygen saturation points to inadequate oxygen delivery to the body, a primary concern in respiratory failure. Normally, healthy individuals maintain oxygen saturation levels above 95%. When these levels drop significantly, it suggests that the lungs are not effectively transferring oxygen into the bloodstream.

Inadequate breathing signifies a failure in the respiratory system's ability to ventilate properly. This may manifest as shallow or labored breathing, indicating that the patient is not able to exchange gases effectively, which could lead to carbon dioxide retention and subsequent respiratory acidosis.

Altered mental status is a critical sign that usually indicates insufficient oxygen supply to the brain. Hypoxia can cause confusion, lethargy, or even loss of consciousness, making it a key indicator of deteriorating respiratory function.

Together, these signs paint a clear picture of respiratory failure, where the body is unable to maintain sufficient oxygen levels or remove carbon dioxide effectively, necessitating immediate medical intervention.
