When you use our oxygen concentrator, the main precautions for oxygen inhalation are:
(1) Closely observe the effect of oxygen therapy. For example, symptoms such as dyspnea are relieved, and the heartbeat is normal or close to normal, indicating that oxygen therapy is effective. Otherwise, the cause should be found and dealt with in time.
(2) High-concentration oxygen supply should not be used for too long. It is generally believed that oxygen inhalation concentration > 60% for more than 24 hours may cause oxygen poisoning.
(3) High-concentration oxygen inhalation for patients with acute exacerbation of chronic obstructive pulmonary disease may lead to respiratory depression and worsen the condition. Generally, controlled (that is, low-concentration continuous) oxygen inhalation should be given.
(4) Pay attention to heating and humidification in oxygen therapy. Maintaining a temperature of 37 °C and a humidity of 95% to 100% in the respiratory tract is a necessary condition for the normal clearance function of the mucociliary system. Therefore, inhaled oxygen should be passed through a humidification bottle and necessary heating devices, which is order to prevent inhalation of dry and cold oxygen to stimulate and damage the airway mucosa, cause phlegm to dry and affect the "scavenger" function of cilia.
(5) To prevent pollution and blockage of catheters, nasal congestion, oxygen delivery catheters, humidification and heating devices, and ventilator piping systems should be regularly replaced and cleaned and disinfected to prevent cross infection. Oxygen inhalation catheters and nasal obstruction should be checked for blockage of secretions at any time and replaced in time. All these can ensure effective and safe oxygen therapy.
