What did we do last time?

Slide 3 - Tekstslide

Ways of breathing

Slide 4 - Tekstslide

Breathing in general
Inhaling: flow of air fill the lungs -> chest cavity needs to expand
Exhale: flow of air leaves the lungs -> chest cavity needs to shrink

Slide 5 - Tekstslide

Breathing in & out
Two ways to breath:
   - Chest breathing        - Abdominal breathing

Intercostals:
  - Muscles between your ribs

Diaphragm:
- A sheet of muscle that separates your chest area from your abdominal cavity



Slide 6 - Tekstslide

chest breathing
In chest breathing (thoracic breathing), the ribs and the breastbone move.

Breath in:
Intercostal muscles tense --> moves your ribs and breastbone up,

Breath out:
Intercostal muscles relax --> moves your ribs and breastbone down.

Slide 7 - Tekstslide

abdominal breathing
In abdominal breathing (diaphragmatic breathing), the diaphragm and abdominal wall move.

Breath in:
The diaphragm contracts, making it move downwards

Breath out:
The diaphragm relaxes, making it move back upwards to normal position.
(Extra strong exhalation: abdominal muscles contract) 

Slide 8 - Tekstslide

Chest breathing
Abdominal breathing
  • Most people
  • Ribs move up and down
  • This movement 'sucks' air into the  lungs
  • Often learned behaviour
  • Diaphragm moves up and down
  • This movement 'sucks' air into the lungs
Many people use a mix of these types of breathing

Tidal volume:
- The amount of air you breathe in or out with each regular breath.
