Discuss the different types of devices for measuring respiratory rate including normal ranges of rate, indications, operation, advantages and disadvantages devices.
Respiration is a form of a metabolic process that all living organisms go through. During inhalation when a person breathes in, oxygen is taken in. When a person exhales, carbon dioxide is released into the surroundings. Respiration involves gaseous exchange therefore is said to be a chemical process while breathing is a physical one. Organisms get their energy from the mix of glucose and oxygen to make carbon dioxide, water and ATP (energy in cells). Respiration rate refers to the number of breaths a person takes in one minute. The following essay will discuss how respiratory rate is measured including the ranges of rates, indications, operations and the advantages and disadvantages of the devices.
The following diagram illustrates inhalation and exhalation:

The unit for respiration rate is stated as breaths per minute (BPM). Respiration rate is taken when a person is at rest and counted by the number of chest rises by the person. When measuring respiration, it is also vital to check if the person has any trouble breathing.
What is the normal breathing rate?
For healthy adults the range is 12-20 breaths per minute.
Table showing average respiratory rate according to age
AGE BREATHS PER MINUTE
Birth to 6 weeks old 30-60
6 months 25-40
3 years 20-30
6 years 18-25
10 years 17-23
Elderly? 65 years 12-28
Elderly? 80 year 10-30
Respiratory rate is to assess how fast or slow a person’s lungs are working. The aim is to conclude if the respirations are abnormally slow, abnormally fast, normal or non-existent.
What factors affect respiratory rates?
Age- young children breathe faster
Pain- this increases respiration rate
Emotion- increases respiration rate
Fever/illness- increases respiration rate
