(2) suck with normal saline to check whether the catheter is patency, and adjust the negative pressure according to the condition of the child and the viscosity of sputum overflow

(3) adults 300-400mmhg, children 250-300mmhg, connected to the sputum suction tube to test whether the normal saline suction.

(4) hold the suction cup tube in the left hand and fold the end; hold the suction cup tube in the right hand with gloves and insert it into the mouth to the throat gently. Then relax the end of the catheter and absorb the secretions in the pharynx.

3. Before sputum aspiration, fold the rubber tube into a V shape, start the machine to make the negative pressure reach the required range, then insert the patient's sputum resistance site, and immediately restore the rubber tube to its original state for sputum aspiration.

4. In the process of sputum aspiration, clean the exhalated secretions at any time, observe the change of respiratory rate before and after, and pay attention to the character, quantity and color of the exhaled substances, and make records as required.

7. The buffer bottle ACTS as a buffer against airflow. It is strictly prohibited to use as a liquid storage bottle to avoid liquid entering the pump body and damaging the machine.

8. After use of dental suction unit , make sure the negative pressure is lower than 0.02kpa before shutdown
