What is the most accurate method of calculating a respiratory rate?

  • Counting the number of respiratory cycles in 15 seconds and multiplying by 4.

  • Counting the number of respiratory cycles in 1 minute. One cycle is equal to the complete rise and fall of the patient’s chest.

  • Not telling the patient as this may make them conscious of their breathing pattern and influence the accuracy of the rate.

  • Placing your hand on the patient’s chest and counting the number of respiratory cycles in 30 seconds and multiplying by 2
