(7) When his chest rises, stop blowing and quickly remove your mouth from his. Take another
deep breath while listening for his exhalation. (If his exhalation is noisy, elevate his jaw
further.)
(8) When exhalation is finished, blow in the next deep breath. The first 5 to 10 breaths must be
deep (except for an infant or small child) and given at a rapid rate in order to provide rapid
reoxygenation. Thereafter, continue breathing at a rate of 12 to 20 times a minute until the
casualty begins to breathe normally.
CAUTION: Excessively deep and rapid breathing may cause you to become faint, to
tingle, or even lose consciousness. Therefore, after the first 5 to 10 breaths, adjust your
breathing to a rate of 12 to 20 times a minute with only moderate increase in normal
volume. In this way, rescue breathing can be continued for long periods without fatigue.
(9) After performing rescue breathing for a period of time, you may notice the victim's stomach
is bulging. This is from air being blown into the stomach instead of the lungs. Although
inflation of the stomach is not dangerous, it makes inflation of the lungs more difficult.
Therefore, when you see the stomach bulging to a marked degree, apply gentle pressure to it
with your hand between inflations.
(10) Remember: Keep the air passages as clear of fluid and other obstructions as possible; keep
the head back, the neck stretched, and the chin pulled forward; readjust position if air does
not flow freely in and out of casualty; do not breathe too forcibly or in too large a volume if
casualty is an infant or small child; in infants seal both the mouth and the nose with your
mouth, and blow with small puffs of air from the cheeks rather than from the lungs; if you
become distressed as a result of the shallow breaths, interrupt the blowing long enough to
take a deep breath, then resume blowing.
11. TREATMENT OF BURNS
Whenever someone suffers a burn, you should be able to estimate the seriousness, or degree, of the
burn. So the first question to answer, is this: How serious is the burn? A second question is this: What
caused the burn--electrical contact, a hot object, steam, dry heat, chemicals, radiation, or what? A burn
should be treated according to the seriousness and the nature of the burn. Minor burns are those in which
no blistering or charring exists and where only small skin areas are involved. Serious burns are those in
which there is blistering or charring, or those in which large areas of the body are involved.
a. Degree of Burn. Burns are usually classified according to the depth to which the skin has been
injured. Data in the chart below will help you recognize how serious a victim's burns are.
