Trace the signals of the Hering-Breuer inflation reflex
intrapulmonary stretch receptor
Vagus
DRG or Apneustic center
What does deep inspiration do to the number of nerve impulses sent by the Hering-Breuer inflation reflex
Increases
When is the Hering-Breuer inflation reflex activated
TV > 1-1.5
Involves inspiration followed by inspiration
paradoxical reflex of Head
Reflex that determines the inspiratory effort needed to achieve a certain tidal volume
Gamma efferent response
3 things that stimulate juxtapulmonary receptors
engorgement of pulmonary capillaries
pulmonary edema
irritant chemicals
What does stimulation of the J receptors cause
tachypnea
Two affects of Aortic and Carotid baroreceptors when they are stimulated by increased BP
Inhibit vasomotor center
Inhibit DRG- hypoventilation
Somatic pain's affect on respiration
hyperventilation
Visceral pain's affect on respiration
hypoventilation
What does an increase in body temperature do to respirations
increases
What are the factors that cause hyperpnea during exercise
Motor cortex
Proprioceptive receptors
Increase in Temp
Increase in metabolism
What factors are not involved with hyperpnea
Increase in CO2
Decrease in O2
Type of breathing pattern that results from noninhibition of apneustic center
Apneustic

long inspiration-short expiration-long inspiration
Type of breathing pattern that results from H+ ions stimulating peripheral chemoreceptors
Kussmaul breathing

Deep rapid breathing
Type of breathing pattern that results from increased ICP
Biot's

apnea-4-5 breaths with same TV-apnea
Type of breathing pattern that results from brain damage or severe heart disease
Cheyne-Stokes

apnea-gradually increasing TV- apnea
3 characteristics of primary alveolar hypoventilation syndrome
Periods of apnea (asleep and awake)
Elevated PaCO2 in absence of disease
Flat CO2 ventilatory curve
