BREADTH HOLDING TIME SECONDS COUNTED
AFTER NORMAL
INHALATION:
After we inhale, our lungs are filled with
oxygen. There is very little carbon
dioxide, as a ratio of the total gasses in
our lungs. If we hold our breath, the
oxygen will be taken into the blood
slowly, and the CO2 from the blood
will slowly be released into the lungs. We
will be able to hold our breath for a
while, until the CO2 ratio is high enough
to trigger the feeling of pressure to
exhale.

AFTER NORMAL
EXHALATION:
If we exhale first, then hold our breath
out, there is very little air of any sort in
our lungs. CO2 continues to flow in from
the blood stream at the same rate as it
would if we were holding our breath after
an inbreath. So the ratio of CO2 in the air
in our lungs goes up faster, as it is a
larger percentage of a smaller total. The
pressure to breathe arises much faster.
16
AFTER DEEP
INHALATION:
The air containing the oxygen is
absorbed by the body and exchange
takes place.
18

2. AFTER DEEP
EXHALATION:
NO more oxygen is available for
exchange so it is slower, as only
carbondioxide is available.

AFTER
HYPERVENTILATION FOR
15 SECONDS:
Icreased rate and depth of breathing.
Increased PH because of less CO2
consumption. It also increases ventilation
so rate is increased.
