respiratory system applied aspects
• Tachypnoea
refers to an increase
in the rate of respiration.
Bradypnoea
• means decrease in the
rate of respiration.
Apnoea
refers to the temporary
cessation of breathing.
Hypoventilation
• term is used to describe
a decrease in the rate
and force of respiration.
Hyperventilation
refers to an increase in
the rate as well as
force of respiration .
hypercapnea
• . Increased level of CO2 in the blood.
• Not present in all types of hypoxia
• Only in hypoventilation and circulatory failure.
Dyspnea
• means mental anguish associated
with inability to ventilate enough to satisfy
the demand for air.
A common synonym is air hunger.
apnoea
• Apnoea refers to a temporary cessation of breathing.
Voluntary apnea
refers to a temporary arrest of breathing due to the voluntary control of respiration. It is also called breath-holding.
Apnea after hyperventilation occurs due to the reduced stimulation of respiratory centre owing to CO2 wash caused by hyperventilation
Deglutition apnea occurs reflexly during swallowing (about 0.5 s)
.Sleep apnea refers to the cessation of breathing for a brief period (10 s) during sleep
periodic breathing
• Periodic breathing is characterized by the alternate periods of respiratory activity and apnea.
•
Cheyne–Stokes respiration
: alternate periods of respiratory activity and apnea occur at regular intervals and during the period of respiratory activity there is waxing and waning of tidal volume. The duration of one cycle is about 1 min
biot's breathing
•
Biot’s breathing
is a type of periodic
breathing showing alternate periods of
respiratory activity and apnoea.
It differs from the Cheyne–Stokes
breathing in following aspects:
It occurs at irregular intervals,
There is no waxing and waning of tidal volume
