Oxygen therapy precautions

- Jun 15, 2019-

(1) Close observation of the effect of oxygen therapy, such as relief of symptoms such as dyspnea, normal or near normal heartbeat, indicates that oxygen therapy is effective. Otherwise, you should find out the reason and deal with it in time.

(2) High concentration oxygen supply should not be too long. It is generally considered that the oxygen concentration is >60% and lats for more than 24 hours, oxygen poisoning may occur.

(3) The high concentration of oxygen in patients with acute exacerbation of chronic obstructive pulmonary disease may lead to respiratory depression and deterioration of the disease. Generally, it should be controlled (ie low concentration continuous) to take oxygen.

(4) Oxygen therapy should be warmed and humidified. Maintaining 37 °C temperature and 95%-100% humidity in the respiratory tract is a necessary condition for the normal removal function of the mucociliary system. Therefore, the inhaled oxygen should pass through the humidification bottle and the necessary heating device. To prevent the inhalation of dry and cold oxygen to stimulate the airway mucosa, causing dry knots and affecting the "scavenger" function of cilia.

(5) To prevent contamination and catheter blockage, nasal plugs, oxygen delivery catheters, humidification heating devices, ventilator piping systems, etc. should be regularly replaced and cleaned and disinfected to prevent cross-infection. Oxygen inhalation catheter and nasal plug should be checked at any time to check for secretion blockage and replace it in time. To ensure effective and safe oxygen therapy.
