Respiratory support during first aid pre-hospital

Respiratory support during first aid

Breathing and support during pre-hospital are often overlooked first aid measures. Everyone needs to realize that respiratory support, like cardiopulmonary resuscitation, is an urgent on-site first-aid measure. If an effective opportunity is missed, the patient will lose precious lives.

So what is respiratory support? Respiratory support refers to emergency treatment measures taken when the patient’s spontaneous breathing cannot meet their own physiological needs. There are 5 measures that can be taken pre-hospital, namely: oxygen supply, airway management and maintenance, artificial airway establishment, artificial respiration, and the application of related drugs. 

Regardless of men, women, and children, regardless of when, where, and what disease, patients have the following two points at the same time, which are indications for on-site respiratory support:

 Patient’s spontaneous breathing is abnormal, manifested as shallow, slow, irregular, or respiratory arrest.

B  Hypoxia manifestations: cyanosis (lips, complexion, and extremities gray or blue), blood oxygen saturation is less than 90%. In the event of the above, first responders should race against time and immediately implement respiratory support for them.

Breathing has essential meaning to life, without breathing, there is no life. However, sometimes respiratory support is neglected in pre-hospital emergencies: the patient has a cardiac arrest, and most doctors know to perform CPR immediately. However, if the patient stops breathing or cannot provide enough oxygen for spontaneous breathing, some doctors fail to implement respiratory support in time or fail to grasp the methods and essentials of respiratory support. As a result, some patients died of hypoxia or asphyxia before or after admission. Sometimes even if they survived by chance, the patient was left with lifelong disability due to prolonged severe hypoxia.

So everyone must pay attention, especially if family members suffer from chronic respiratory diseases, low blood oxygen saturation, heart disease, and other diseases, they must use an oxygen concentrator, and it is a medical-grade oxygen concentrator above 5L. Daily oxygen therapy can use low flow. Once breathing support is needed, the high flow must be used to inhale oxygen for a long time to prevent hypoxia and miss the best time for rescue.

In fact, not all oxygen concentrators can play an important role in respiratory support.

First, above 5L/min of the oxygen concentrator with oxygen purity monitoring function is required, which is a crucial point.

Second, the oxygen concentrator parameter requirements, internal configuration, oxygen output pressure, oxygen purity, oxygen stability, etc., must meet the standards for medical rescue.
