Be careful with oxygen. - Don't be blind
Oxygen inhalation can relieve fatigue and reduce pressure, but if blind unlimited oxygen inhalation, high concentration "oxygen therapy" can cause complications, then inhibit breathing, oxygen poisoning, discomfort and pain after the sternum, especially many of us hypoxic people blindly pursue high concentration oxygen, in fact, this is not correct, at present, the household oxygen machine does not belong to hyperbaric oxygen and pure oxygen. So it does not need to worry about oxygen poisoning, but oxygen health care must also be appropriate to moderate.
Oxygen inhalation needs to pay attention to some precautions, such as the following: ☟☟
1, For the purpose of health care oxygen flow should not be greater than 3 liters/minute, the sum of the time used in a day should not exceed 1-2 hours. High concentration of oxygen should not be too long, it is generally believed that oxygen concentration >60%, lasting more than 24 hours, is likely to occur oxygen poisoning. In acute respiratory failure such as respiratory failure, acute respiratory distress syndrome, acute poisoning (such as carbon monoxide poisoning or gas poisoning) respiratory depression, it is necessary to use high concentration or pure oxygen every minute for rescue, but it is not suitable for long-term use to prevent oxygen poisoning or other complications.
Under normal circumstances, our lungs maintain the balance with the external atmospheric pressure by filling with nitrogen, which is difficult to be absorbed by the lungs under normal pressure. When inhaling air with high oxygen content, the nitrogen content in the alveoli gradually decreases, which may lead to the absorption of oxygen by the alveoli, resulting in the decrease of internal pressure in the alveoli, resulting in attasis.
2、Giving high concentration oxygen to patients with acute exacerbation of COPD may lead to respiratory depression and worsen the condition, and generally controlled (that is, low concentration continuous) oxygen should be given; When chronic respiratory failure is decompensated, the increase of partial pressure of blood oxygen must be considered in oxygen inhalation. Too high partial pressure of blood oxygen can weaken the reflex stimulation of carotid sinus to the respiratory center, thus reducing ventilation and possibly aggravating carbon dioxide retention. So be careful with oxygen.
3, To prevent pollution and catheter blockage, nasal congestion, oxygen catheter, ventilator pipeline system should be regularly replaced and cleaned and disinfected to prevent cross infection. Oxygen inhalation catheter, nasal congestion should always pay attention to check whether there is secretion blockage, and timely replacement. To ensure effective and safe oxygen therapy.
4、Oxygen therapy should pay attention to heating and humidification, and maintaining a temperature of 37 ° C and 95% to 100% humidity in the respiratory tract is a necessary condition for the normal clearance function of the mucociliary system in the tracheal
In short, when taking oxygen, it should be noted that improper use of oxygen also has side effects, especially for patients. Under normal circumstances, healthy people are generally not hypoxic, and the oxygen delivered to human tissues always exceeds the amount of oxygen consumed by the tissues. The atmosphere contains about 20% oxygen, which is relatively constant.
