Overview

    • How to Measure

    • Count the patient's breaths over 30 seconds to one minute while ostensibly measuring the pulse.

      • Normal Range

      • 12 - 20 breaths per minute

    • Significance

    • The diaphragm has both somatic and autonomic innervation, and thus the respiratory rate can be altered both voluntarily and and involuntarily in response to physiologic or pathologic stimuli.

Tachypnoea

  • Respiratory rate greater then 20 breathes per minute.

    • Causes of Tachypnoea

    • Physiologic - during exercise or at high altitude
    • Anxiety
    • Metabolic acidosis - abdominal pathology, sepsis
    • Pulmonary embolism
    • Pneumonia
    • Asthma
    • Respiratory failure

Bradypnoea

  • Respiratory rate less than 12 breaths per minute.

    • Causes of Bradypnoea

    • Respiratory suppression
    • Drugs - opioids
    • Respiratory failure
    • Hypothyroidism
    • Raised intracranial pressure
