Which of the following is NOT a sign of severe respiratory distress?

Stable pulse oximetry is considered a significant indicator in assessing respiratory distress. In cases of severe respiratory distress, one would typically expect to see fluctuating or low oxygen saturation levels, as the body struggles to adequately oxygenate itself due to impaired respiratory function.

On the contrary, diaphoresis (sweating), orthopnea (difficulty breathing while lying flat), and pedal edema (swelling in the feet and ankles) are all commonly observed signs that indicate a person is experiencing significant respiratory distress or related cardiovascular issues. These symptoms reflect the body's response to inadequate oxygenation or increased respiratory effort. A patient with stable pulse oximetry would likely not be showing signs of severe respiratory distress, as this suggests that their oxygen levels are within an acceptable range, thus indicating effective respiratory function.
