What is the definition of tachypnea?

Tachypnea is defined as rapid breathing, characterized by an increased respiratory rate. This condition can be a physiological response to various stimuli, such as exercise, anxiety, fever, or respiratory illness. The normal respiratory rate for adults typically ranges from 12 to 20 breaths per minute; when this rate exceeds 20 breaths per minute at rest, it is considered tachypnea. Understanding this definition is crucial for healthcare professionals, as tachypnea can indicate underlying health issues that may require further assessment and intervention.

The other options refer to different medical terms and conditions: excessive sweating relates to hyperhidrosis, insulin resistance pertains to metabolic conditions like type 2 diabetes, and the forcible emptying of gastric contents describes the action of vomiting. These definitions show how important it is to distinguish between terms that can appear similar but have distinct meanings.
