What are the instructions for using the oxygen bag

Usually, if you have cardiovascular disease, you should prepare an oxygen bag at home, which is of great help to your body. This is mainly because patients with cardiovascular disease will temporarily feel difficulty breathing or even chest tightness, so they can use oxygen bags to provide their bodies with sufficient nutrition. Moreover, medical devices such as oxygen bags can not only treat cardiovascular disease, but also relieve asthma or high blood pressure.

1) After the oxygen bag is filled with oxygen, clamp the rubber tube with a screw clamp. To check whether the oxygen bag is leaking, you can press the bag with both hands and hold it close to your cheek. If there is a leak, you can feel a flow of air on your cheek and sometimes you can even hear the sound of air flow. If any leak is found, it must be repaired promptly to ensure timely oxygen supply.

2) Connect the sterilized nasal cannula to the glass tube and tighten it to the oxygen bag leather tube; open the spiral clamp and point the mouth of the nasal cannula to the cheek. If you feel airflow, it means the nasal cannula is unobstructed. You can also put the mouth of the nasal cannula in a cup of cold boiled water. If bubbles escape from the water, it means the nasal cannula is unobstructed, and the amount of oxygen supplied can be understood from the amount of bubbles escaping.

3) Use a cotton swab dipped in cold boiled water to clean one side of the nasal cavity, and then insert a nasal cannula with oxygen and moistened with cold boiled water into the nostril. The technique is to first insert it upwards about 3 cm, then insert it backwards about 7 cm (equivalent to the distance from the tip of the nose to the ear), and then use tape to fix the nasal catheter to the edge of the nostril to prevent it from slipping. At present, the design of disposable oxygen tubes is becoming more and more reasonable. They are very convenient to use, can be taken and carried at any time, do not need to be inserted too deep, are less irritating, more comfortable, and easy for patients to accept.

4) When the pressure in the oxygen bag decreases, you can add pressure with your hands to facilitate the discharge of oxygen; or place the oxygen bag under the patient's head like a pillow and use the weight of the patient's head to allow the oxygen to be discharged.

5) If conditions permit, a humidifier bottle can be added in the middle of the oxygen bag hose to moisten the oxygen to prevent the patient from damaging the respiratory mucosa due to inhaling dry oxygen. The humidification bottle is filled with 1/3 cold boiled water. There are two holes on the bottle stopper for inserting two long and short glass tubes. The upper end of the long glass tube is connected to the oxygen bag leather tube, and the lower end should be 2 to 3 cm below the water surface to allow oxygen to escape from under the water through the glass tube, and then enter the short glass tube whose lower end is 4 to 5 cm from the water surface and the leather tube and nasal catheter connected to its upper end. In this way, the oxygen entering the patient's nasal cavity is humidified by water, making the patient feel comfortable.

However, you must understand the usage of oxygen bags clearly. If you don't, there is no way to guarantee that the patient can absorb oxygen accurately and in a timely manner. Especially if you find that your oxygen bag is leaking, you should repair it immediately. Otherwise, the patient will not be able to breathe oxygen, and may even inhale other dust.
