 What is CPR?

Cardio-Pulmonary Resuscitation

an emergency procedure in whichthe heart and lungs are made to

workmanually compressing the chestoverlying the heart and forcingair into the lungs

used to maintain circulation when

the heart stops pumping, usuallybecause of disease, drugs, ortrauma

2 Methods of CPR 

The Silvester Method patient is laid on

their back, their

arms are raised

above their head to

aid inhalation and

then pressed against

their chest to aid

exhalation

repeated sixteen

times per minute

sank because of the hole made

when the merchant vesselcollided with them

ISSUE #2: What do you think is the

reason why the Coast Guard ship didn¶t

changed its location even after the

collision?

DECISIO N: The Coast Guard ship

has a higher momentum than

the merchant vessel that¶s

why it stays in its location

even after they collided.

Density

At first the density of the ship isless dense than the water that¶s

 why it is floating. But when themerchant vessel hit it and made adeep hole the weight of the shipchanges. Because of the water thatentered the ship, its density

increases which is now greaterthan the density of water causingit to sink.

 Momentum 

It is simple expressed as, the

higher the mass, the higher is its

 momentum . It might be the reason

why the ship doesn¶t change its

location even after the pressure

caused by the collision. The ship

has greater mass than the merchant

vessel so it has greater momentum .

Law of Interaction

The law of interaction states

that for every action there

is an equal and oppositereaction. When rendering CPR,

you exert force to the chest

of the patient, then the

force constantly bounce back

to your palms.
