3. Implementation of rescue breathing and closed-chest cardiac massage is performed in the following sequence:

1). 1. The injured is to be lied down on the back with a cushion under his neck with his head tossed back. 2. Clean out his oral cavity and extract the dentures. 3. The rescuer takes a deep breath and blows the air into the injured person’s mouth. 4. The rescuer presses onto the chest 4-5 times (chest deflection is 4-5 cm) with a frequency of 1time per second. 5. The rescuer repeats the operation 4) 10 - 15 times per minute until the breath and heartbeat are regained. 6. Effectiveness evaluation criteria: the pulse appearance, respiration, miosis, flushed skin. 7. If the breath and heartbeat aren’t regained in 45 minutes and there are no vital signs 6), the death is certified.

The rescuer takes a deep breath and blows the air into the injured person’s mouth. 4. The rescuer presses onto the chest 4-5 times (chest deflection 4-5 cm) with a frequency of 1 time per 2 seconds. 5. The rescuer repeats the operation 4) 10 - 15 times per minute until the breath and heartbeat are regained. 6. Effectiveness evaluation criteria: pulse appearance, breathing, miosis, flushed skin. 7. If the breath and heartbeat aren’t regained in 40 minutes and there are no vital signs, 6) the death is certified.

If the breath and heartbeat aren’t regained in 10 minutes and there are no vital signs 6) the death is certified.

4) 1. The injured is to be lied down on the back with a cushion under his neck and his head tossed back. 2. Clean out his oral cavity and extract the dentures. 3. The rescuer takes a deep breath and blows the air into the injured person’s mouth. 4. The rescuer exerts pressure on the chest for 4-5 times per a second (chest inflexion is 4-5 cm). 5. The procedure is repeated 4) 10-15 times per a minute until the breath and heartbeat are regained. 6. Effectiveness evaluation criteria: pulse appearance, breathing, miosis, flushed skin. 7. If the breath and heartbeat aren’t regained in 30 minutes and there are no vital signs 6) the death is certified.

4. Due to the scale and consequences emergency situations are classified as follows:

1). State level; region level; district level; local level, on-site level.

2). State level; region level; local level, on-site level.

3). State level; regional level; local level; on-site level.

4). State level; regional level; region level; district level; local level.
