First, the purpose of using a simple respirator:


1. Maintain and increase air volume;


2. Correct life-threatening hypoxemia.


Second, the indications for a simple respirator:


1. Respiratory arrest or respiratory failure caused by various causes and breathing tube during anesthesia

Reason.


2, transport patients: for mechanical ventilation patients for special inspections, access to the operating room and so on.


3. Temporary replacement of ventilator: when it encounters special circumstances such as failure of breathing machine, power outage, etc., it can be temporary.

Use a simple respirator instead.


Third, use an easy respirator to prepare items:


Easy respirator.


Fourth, the use of simple breathing apparatus steps:


The rescuer stood at the top of the right side of the patient's head, went to the pillow, and connected the oxygen to the simple respirator. The flow of oxygen was 8L-10L/min. The patient leaned back and raised the patient's jaw and tightened the mask. The hand used the "EC" technique. The mask is fixed, and the other hand regularly squeezes the respiratory sac, so that the gas enters the patient's lungs through the inhalation valve. When it is relaxed, the lung gas is discharged with the expired flap; 500-600 ml of air is given each time, and the frequency of squeezing is Adults 12-20 minutes, increase in children's discretion.


Fifth, the use of simple respirator precautions:


1, the mask must be tightly linked to the nose, otherwise prone to leakage.


2, if the patient has spontaneous breathing, should be synchronized with it, that is, the patient's inhalation at the beginning of the homeopathic pressure squeeze the respiratory sac, to reach a certain amount of tidal volume will completely release the airbag, let the patient complete the exhalation action.


Attachment: Introduction to EC techniques


When using a simple respirator, the left hand mother finger and index finger hold the mask in a C shape, and the middle finger and ring finger hold the patient's jaw. The middle finger, ring finger, and little finger (constitute "E") hook the lower jaw and open the airway; the thumb and index finger (constitute "C") fix the mask.
