The specific cleaning and disinfection procedures are as follows: ① Cleaning: you can choose to clean manually, you can also choose to clean and disinfect the machine for cleaning. Cleaning will be removable part of the full disassembly, the use of enzyme cleaning agent soak, and brush or other cleaning tools to thoroughly scrub, so that the residual stains on the surface of the simple respirator is completely removed.
② Disinfection / sterilization: In addition to cleaning and disinfection machine, clinical disinfection / sterilization methods commonly used: disinfectant immersion disinfection, the conditions of the medical institutions can also choose to acid oxidation potential water disinfection or low-temperature sterilization. Disinfection can choose to contain 500mg/L chlorine disinfectant immersion, the mask, balloon, pressure safety valve, intake valve, exhalation valve completely submerged in disinfectant, so that the disinfectant and the internal and external surfaces can be fully contacted, the role of 30 minutes.
Note that, before immersion, the gas will be pumped out of the mask, so as not to float the mask can not be completely submerged in the liquid surface and can not achieve the disinfection effect. Rinse thoroughly after disinfection, sterile towel dry, should not be natural drying. When using acidic oxidation potential water disinfection, should follow the relevant standards and requirements to ensure the disinfection effect.
For medical institutions with less frequent use, low-temperature sterilization is recommended.
01
Purpose of the simple respirator
1. Maintain and increase the body ventilation
2. Correct the life-threatening hypoxemia
02
Adaptation of the simple respirator
1. Resuscitation of respiratory depression and respiratory failure of the body caused by various reasons.
2, casualty transportation, with other oxygen-demanding treatment.
3, special circumstances, such as ventilator failure, power outage, etc. can be temporarily applied to replace.
03
Contraindications to the simple respirator
No absolute contraindications.
Relative contraindications and cause analysis:
1. Tension pneumothorax and mediastinal emphysema without drainage: in principle, patients with pneumothorax as long as the independent respiration can maintain the basic ventilation, clinical symptoms are not very serious, then do not carry out mechanical ventilation, if you have to carry out mechanical ventilation, mechanical ventilation must be carried out before closed drainage, especially tension pneumothorax, mediastinal emphysema, or else the mechanical ventilation will exacerbate the pneumothorax, resulting in counterproductive results.
2. Pulmonary alveoli and pulmonary cysts: because mechanical ventilation is positive pressure ventilation is easy to cause pulmonary alveolar rupture caused by pneumothorax, mediastinal emphysema and other complications.
3. Hypovolemic shock without supplementation of blood volume: in principle, hypotensive shock should be listed as a contraindication before correction, when mechanical ventilation must be carried out, low-pressure ventilation should be taken and the application of antihypertensive drugs to maintain blood pressure.
4. Hemoptysis or serious aspiration asphyxia: hemoptysis or aspiration asphyxia should not be immediately mechanical ventilation, because mechanical ventilation will be the blood clots or aspirated material into the small airway caused by obstructive pulmonary atelectasis, should be suctioned out of the blood or aspirated material before mechanical ventilation. In the case of persistent bleeding, ventilation should be performed in a head-down position to prevent blood from flowing into the small airways.
5, acute myocardial infarction: the past that acute myocardial infarction is contraindicated mechanical ventilation, now that the infarction is accompanied by pulmonary edema, expiratory failure, based on the treatment of the primary pathology can be mechanical ventilation, can be used to low-pressure ventilation and pay attention to changes in condition.
