What is the Difference Between Nasal Ett Tube Oxygen Inhalation and Mask Oxygen Inhalation? - 翻译中...

Oxygen is very important to the human body. Under normal conditions, healthy people naturally breathe air and use the oxygen in it to maintain metabolic needs. When sick or in some abnormal state, it is necessary to inhale oxygen through certain equipment at home, clinics, and hospitals. For people with breathing difficulties, it is necessary to relieve symptoms through oxygen inhalation, especially for the elderly because many diseases require oxygen inhalation. For oxygen inhalation, prong nasal inhalation and mask inhalation of oxygen can be used. Then let's learn about prong nasal inhalation. What is the difference between oxygen and mask oxygen?


1. Mask oxygen inhalation method


It can be divided into open and closed mask method. The open type is to place the mask at a distance of 1 to 3 cm from the patient's mouth and nose, which is suitable for children without any discomfort. The closed mask method is to tightly cover the mask on the nose and mouth and fix it with an elastic band. It is suitable for people with severe hypoxia. The oxygen inhalation concentration can reach 40% to 50%, and it feels more comfortable, without mucosal irritation and dry feeling. However, the oxygen consumption is large, and there are disadvantages of inconvenience in eating and expectoration.


2. Prong nasal oxygen inhalation


The prong nasal method is to insert a catheter (usually a urinary catheter) through the nostrils into the back of the soft palate at the top of the nasal cavity. The oxygen concentration is constant, but it will feel uncomfortable and easily blocked by secretions after a long time. Nasal congestion and prong nasal oxygen inhalation methods are generally only suitable for low-flow oxygen supply. If the flow rate is relatively large, it will be unbearable due to the large flow rate and impact force, and it will easily lead to drying of the airway mucosa.


3. The difference between prong nasal oxygen inhalation and mask oxygen inhalation


Mask oxygen patients are prone to carbon dioxide retention, because the exhaled carbon dioxide is inhaled after accumulation in the mask. Prong nasal inhalation of oxygen loses a lot of oxygen. Mask oxygen inhalation patients are suitable for patients with low blood oxygen saturation, patients with hypoxemia with hypercapnia, patients with COPD and patients with chronic pulmonary heart disease.


Indications for nasal ett tube patients:

① Respiratory system diseases affect lung capacity.

② Heart insufficiency, making the lungs congested and causing breathing difficulties.

③ Poisoning, so that oxygen can not penetrate into the tissue by capillaries and produce hypoxia.

④ Coma patients, such as cerebrovascular accident.

⑤ Some patients after surgery, patients with hemorrhagic shock or craniocerebral disease, irregular long labor or poor fetal heart rate, etc.


Now everyone can clearly understand the difference between these two methods of oxygen inhalation. In fact, for patients, when the general symptoms are not particularly serious, more people use masks to inhale oxygen, and the concentration of oxygen inhalation also needs to be based on the doctor's Do not arbitrarily change the doctor's order for mediation.
