You come upon an unconscious individual with a pulse, they do not appear to be breathing, you are unable to deliver the first breath, the next step is to repeat the head tilt/chin lift maneuver and attempt the breath again.
If they are unresponsive and not breathing, push firmly downwards in the middle of their chest at a regular rate. Ideally, you should alternate two rescue breaths with 30 chest compressions for anyone who has been rescued from drowning. This will help build up a supply of oxygen in their blood. If a person is not breathing and has no pulse, you need to seek emergency help immediately and be prepared to help the victim until emergency help arrives.

Answer:
Pavlov's theory of stimulus substitution is the combination of several techniques that are called the spectrum of the umbrella in classical conditioning. It occurs with the pairing with the new stimulus to the already conditioned stimulus. When this procedure occurs new stimulus paired with the conditioned stimulus, there are chances of replacing already conditioned stimulus with a new stimulus.
We can take an example of a rat that is to be conditioned to respond to a whistle which related to fed then can add a flashlight as a signal with a whistle. When light is there then rat fed. The light signal is then substituted part of the whistle.
