1. How to check whether the suction unit worked well?

Connect the suction unit to the power supply, turn on the switch, and check whether the catheter connected with the suction machine was correct and whether the suction was normal. After adjusting the negative pressure according to the patient's condition and phlegm viscosity (40~53.3KPa), test suction with isotonic saline to check whether the catheter was smooth. The catheter is unobstructed with good suction and can be used.

2. What should I do if I encounter resistance or difficulty in sputum aspiration? 

When encountering resistance, it is not easy to insert the sputum by force, a small amount of sputum reducing solution such as A-chymotrypase can be dropped and knocked on the back to promote sputum aspiration through gentle vibration, or inhaled with ultrasonic atomization to dilute the sputum and then aspirated.

3. How to master the time of sputum aspiration?

When suction sputum for the patient, the action should be gentle, pull upward from the deep, rotate around, suction net sputum. Sputum aspiration time should not exceed 15 seconds each time, so as to avoid hypoxia patients, severe hypoxia sputum aspiration should be given oxygen.

4. What should we observe during sputum aspiration?

In the process of sputum suction with suction machine, attention was paid to the changes of the patients' breathing conditions before and after sputum suction, whether there was any manifestation of hypoxia, the color, amount, smell, nature and viscosity of sputum suction, and whether there was any injury of oral mucosa and the general condition of the patients, and records were made.

5. What are the signs of cardiac arrest?

Sudden loss of consciousness, convulsions or coma, disappearance of carotid artery, respiratory arrest, dilated pupils, pale or blue face.
