Instructions and operating procedures of the manual resuscitator

A. Operation steps

1. Evaluation:

(1) Whether it meets the indications and indications for using a manual resuscitator, with no spontaneous breathing or weak spontaneous breathing.

(2) Assess whether there are contraindications for the use of manual resuscitator, such as moderate active hemoptysis, myocardial infarction, large pleural effusion, etc.

2. Connect the mask, breathing bag and oxygen, and adjust the oxygen flow rate to 8-10 liters/min.

3. Open the airway, clear the upper respiratory tract secretions and vomit, loosen the patient's collar, etc., the operator stands on the patient's head, makes the patient's head tilt back, and lifts the lower jaw.

4. Cover the patient's nose with the mask and press it tightly to prevent air leakage. If the patient uses a manual resuscitator for tracheal intubation or tracheotomy, the sputum should be sucked up first.

5. The method of squeezing the breathing bag with one hand: the right hand EC technique fixes the mask, the left hand squeezes the balloon, and the right arm squeezes the fixed balloon together with the left hand.

6. Pay attention to tidal volume, respiratory rate, inspiratory-expiratory ratio, etc. when using. (1) The general tidal volume is 8-12ml/kg. (2) The breathing rate for adults is 12-16 times/min. When squeezing the airbag quickly, pay attention to the frequency of the airbag and the coordination of the patient's breathing. There should be enough time between the patient's exhalation and the inflation and resetting of the airbag to prevent the airbag from being squeezed when the patient exhales. (3) The inhalation and exhalation time is generally 1:1.5~2 compared with adults. 7. Observe and evaluate the patient. During use, closely observe the patient's adaptability to the respirator, chest and abdomen fluctuations, skin color, auscultation breath sounds, vital signs, and oxygen saturation readings.

B. Attentions.

1. The problem that is likely to occur when using a simple respirator is that the valve leaks, which prevents the patient from getting effective ventilation. Therefore, it is necessary to check, test, repair and maintain it regularly. 2. When squeezing the breathing bag, the pressure should not be too high, squeeze two-thirds of the balloon when there is no oxygen source, and squeeze one-half of the balloon when there is an oxygen source. 3. When it is found that the patient has spontaneous breathing, it should be assisted according to the patient's breathing action, so as not to affect the patient's spontaneous breathing. 4. Psychological care for conscious patients, explain the purpose and significance of applying respirators, relieve tension, make them actively cooperate, and guide patients to "inhale" and "exhale" while squeezing the breathing bag. 5. Disinfect it in time after use, disassemble the parts of the simple respirator in order, and soak in 2% glutaraldehyde alkaline solution for 4-8 hours. After taking it out, rinse all parts with clean water to remove residual disinfectant.
