Explain how respiration is regulated in the event of increased CO2
Central and peripheral chemoreceptors (Aortic/Carotid) detect increase in blood CO2. Detected by inspiratory centre in Medulla Oblongata and sends nerve impulses to inspiration/exhalation muscles. Causes more forceful/frequent inhalation/exhalation.

Respiratory Chemical Formula...
H20 + CO2 - H2CO3 - HCO3 + H+

Sternoicleidomastoid, Scalenes and Pectoralis Minor are also involved
4 of 14
Explain normal EXHALATION..
Diaphragm and external intercostals relax.

What is the TICLS Assessment?
Tone, Interactiveness, Consolability, Look/Gaze, Speech/Cry - Assesses the level of consciousness
10 of 14
Name the areas of observable retraction..
Intercostal, Subcostal, Substernal, Clavicular, Suprasternal, Paratracheal (Older child)

How would you monitor breathing?
Oxygen saturations, Respiratory rate and pattern, Heart rate, Presence of respiratory distress
13 of 14
What is the relationship between blood pH level and CO2?
An increase in CO2 levels produces more H+ ions, this results in reduced pH level (more acidic).
