Oxygen Bag Use Precautions
May 28, 2018

Oxygen is essential for humans to maintain normal life activities. High purity oxygen can relieve dyspnea, palpitation, shortness of breath, palpitations, etc. Oxygen bags have good air tightness, soft texture, light weight and easy to use. Widely used in families, emergency treatment of critically ill patients and emergency transport of critically ill patients on the way to use. The oxygen bag is a rectangular rubber pillow. To prevent the rubber in the oxygen bag from sticking, the manufacturer usually puts a barrier agent in the oxygen bag. This is often overlooked before use. Oxygen bags are generally made of single-sided rubber or PVC or TPU-coated fabrics in accordance with the fabric, specifications are 30L, 42L, 50L3 species. In the case of hypoxic continuous oxygen inhalation, the oxygenation of the 42L oxygen bag can be used continuously for about 0.5 hours.

1 The necessity of using oxygen bags

Oxygen bag for respiratory diseases: chronic bronchitis, bronchial asthma, emphysema, chronic obstructive pulmonary disease, pulmonary heart disease pneumoconiosis, silicosis, etc. Cardiovascular and cerebrovascular diseases: coronary heart disease, hypertension, heart failure, rheumatic Heart disease, congenital heart disease, cerebral hemorrhage, cerebral ischemia, cerebral embolism, arteriosclerosis, migraine, etc.; senile diseases, altitude sickness, high altitude sickness, fetal distress and other causes of acute and chronic hypoxia. Temporary oxygen supply and family diseases are temporarily available on various occasions.

Clinical practice has proven that oxygen therapy, with its unique therapeutic mechanism, can effectively treat acute and chronic hypoxic-ischemic anoxia disorders and secondary diseases caused by hypoxia in clinical departments. The use of oxygen bags to supplement oxygen can improve the body's physiology, biochemical environment, and promote the benign cycle of metabolic processes, in order to achieve the purpose of treating diseases, relieving symptoms, promoting rehabilitation, preventing diseases, and improving health.

2 How to use

Before use, connect the rubber hose of the oxygen-filled oxygen bag to the sterile nasal cannula, then place the other end of the nasal cannula into the cup filled with cold water. Turn on the switch. If there is oxygen in the water, it indicates that the oxygen flows out. Smooth, otherwise need to replace the nasal cannula. Before inserting the nasal cannula into the nostril, clean the nostrils with a cotton swab dipped in cold water, and then dip the catheter with cold water for lubrication. At present, there are two commonly used nasal cannulae: one is a thin rubber catheter that needs to be inserted deeper and inserted into the nasopharynx via the nasal cavity. The length of the insertion portion of the nasal cannula is about 2/3 of the distance from the tip of the nose to the ear. The other is a plastic product with a rounded end that can be placed in the nostrils. The oxygen bag can be pillowed under the head of the patient, and the oxygen bag is forced by the weight of the head to allow the oxygen to flow out.

When using, insert the stuffy nose into the patient's nasal cavity, fix the catheter with tape, let the patient's head rest on the oxygen bag, and let the oxygen flow out by pressure. After opening the oxygen bag switch, pay attention to adjust the oxygen flow, generally should start from the low flow, the flow rate should be based on the specific circumstances of the patient, for patients with respiratory failure, the flow should not be large, otherwise it will increase respiratory depression, resulting in Danger. In an emergency, it is also possible to use an oxygen bag directly without a humidified bottle.

3 Precautions

3.1 Make preparations before use. If the home oxygen bag is not easy to be too large, suitable for 71cm × 42cm, in addition to a humidifier bottle, a nasal cannula, just buy home oxygen bags need to constantly inflate and keep tapping, the talc in the bag Take it out so as not to be inhaled by the patient. Before use, connect one end of the hose to the nasal congestion, one end to the humidifying bottle, and then connect the oxygen bag with the other end of the humidification bottle.

3.2 Do not exceed the specified operating pressure of 10.6 kPa when oxygenating. Exceeding the limit pressure of 10.6 kPa will affect the service life of the oxygen bag and even cause the rupture of the oxygen bag. After the oxygen bag is filled, use a screw clamp to clamp the rubber tube to check whether the oxygen bag leaks. Use both hands to press the bag and close to the cheek. If there is a leak, you will feel an air flow, and sometimes you can hear the sound of airflow. If a leak is found, it must be dealt with promptly.

3.3 In use, dip the oxygen delivery tube into a cup filled with water, and slowly loosen the cap to observe that the bubbles are continuously discharged and then used by the patient. During use, the pressure should be reduced, and the amount of gas should also be reduced. At this point can be used outside the bag pressure or open a large head to adjust the oxygen supply. It can also be pillowed under the head of the patient to press the oxygen bag with the weight of the head to allow oxygen to flow out.

3.4 When connecting the humidified bottle, do not invert the two glass tubes to avoid the possibility of water being directly injected into the respiratory tract of the patient due to the pressure of the humidified bottle and causing suffocation.

3.5 The oxygen used for oxygen bags should be ordinary mixed oxygen, which is available in major hospitals and emergency centers. Industrial oxygen should not be used instead.

3.6 If the patient has a cardiopulmonary insufficiency or a critically ill patient in the family, the oxygen bag should be filled with oxygen at any time to be ready for use. It is best to use two oxygen bags and fill it with oxygen. Patients who continue to use oxygen should replace the nasal cannula once a day. When using oxygen bags for the first time at home, it is best to perform under the guidance of medical personnel.

3.7 When a patient drinks water or eats, oxygen should be suspended and oxygen should be given after the water is consumed.

3.8 After use is stopped, it should avoid light and avoid heat, avoid contact with sharp objects and chemicals such as acid and alkali, and excessively squeeze. A small amount of air should be stored in the bag to prevent adhesion of the inner surface during long-term storage.

3.9 Oxygen safety is of utmost importance. When a patient breathes oxygen, the room cannot be exposed to open flames. Families cannot smoke, ignite or spot mosquito coils nearby to prevent explosion.
