2. Respiratory System Physiology
• Inhalation: Act of breathing in; also called inspiration
• Exhalation: Act of breathing out; expiration also used,
but not preferred
• Phases of ventilatory cycle: Inspiratory, hold,
Expiratory, hold
3. Breathing Mechanism-Inhalation
an ACTIVE MOVEMENT
Automatic Control-
Receptors in neck
and brain
Intercostal Muscles and Diagram are contracted
Thoracic cage up-Intra thoracic pressure drop
Air from outside flow in
4. Breathing Mechanism-Exhalation
a PASSIVE MOVEMENT
Intercostal Muscles and Diagram are recoiled
Thoracic cage down-Intra thoracic pressure increase
Air from inside flow out

38. Modeof Ventilator
Basic Mode
of
Ventilator
CPAP (spontaneous mode)
ถ้าผูป่วยไม่หายใจเลย เครื่ องจะไม่มี
้
mandatory breath ช่วยเลย แต่จะมี
back up rate ถ้าผูป่วยมี apnea

39. Basic Type of Mechanical Breath
Type of Mandatory (assisted) Breath
Mandatory breath
Volume controlled breath (VC)
กาหนด volume, flow, flow pattern
Pressure controlled breath (PC)
กาหนด pressure level, inspiratory
time
Spontaneous breath
With or without pressure/ volume
support
Pressure support breath
