1, found that the patient is unconscious, assess the safety of the ward environment, tap both shoulders, call the patient’s name in both ears – lift the quilt to see if the chest is rising and falling (to quickly determine whether there is breathing) – call for a companion, look at the table in time – -Remove the pillow, bed head, bed stall, undress – touch the carotid artery (1001, 1002,…. . 1010) – no pulsation of the carotid artery, no voluntary breathing in the thorax – pad (from the opposite side to the near side), the upper section is flush with the shoulder – compression (arm perpendicular to the chest, compression The midpoint of the line between the two nipples, the line of the left index finger, the midpoint of the right index finger point, the left palm and then the right palm), the frequency is greater than 100 times / min, the depth of compression is greater than 5 cm. (11, 12…. . 10/11, 12. 20/11, 12…. 30) – receive wall oxygen at least 10 l/min, give air twice (EC maneuver, thoracic heave) – compressions (21, 22… 10/21, 22…) . 10/21, 22…. . 20/21, 22…. . 30) – two breaths – compressions (31, 32…. . 10/31, 32…. . 20/31, 32…. . 30) – compressions (41, 42…. . 10/41, 42…. . 20/41, 42…. …30) – air administration on both sides – compressions (51, 52… 10/51, 52…) . 10/51, 52…. . 20/51, 52…. . 30) (five cycles) Touch the carotid artery again. 2, defibrillator to, stop pressing, turn on the machine, set to manual pass, set the defibrillator button to PADDLES key, two electrode plates placed on any part of the patient’s chest wall (ECG shows ventricular coarse fibrillation wave) – left hand reverse take electrode plates – (fully abduct the left upper limb, wipe the skin of the defibrillation site, while assessing the skin, chest skin clean and dry, no moisture, no breakage, no hairy no electrode piece) apply conductive paste to describe the electrode plate position, right hand apical part (left breast lateral, electrode plate midline coincides with axillary midline, upper edge is 7 cm from the axilla), left hand base of the heart (2-4 intercostal space at the right edge of the sternum) – -Tune to 150 joules, discharge electrode plate, evenly apply conductive paste greater than 10*10 cm -Charge -Look around (everyone move aside, I want to defibrillate) -see if the defibrillator is fully charged -while leaving the bed itself to press down with a force greater than 10 kg – fully discharged, power to zero, put back the electrode plate – –CPR again ……5 cycle. 3, disposal supplies: the various parts of the simple respirator fully dismantled, oxygen storage bag with 75% alcohol wipe disinfection; other parts into 500PPM chlorine-containing disinfectant soak for 30 minutes, remove with distilled water rinse clean dry and ready to use. The defibrillator is wiped and dried with a small towel soaked in 500PPM chlorine-containing disinfectant solution, charged, and the index finger is in a spare state. The pad is wiped dry with a small towel soaked in 500Pm and set aside. The gauze is placed in a yellow garbage bag. 4. Hand washing record: CPR successful, no burns on patient’s skin, smooth process, staff safety.
