Which of the key points for attention in oxygen inhalation is wrong? (b)

A. When using oxygen, do a good job in fire prevention, oil prevention, shock prevention and heat prevention, and pay attention to the safety of oxygen use

B. Choose a reasonable oxygen use method and oxygen concentration according to the illness

C. The oxygen in the oxygen cylinder must be used up

D. During oxygen use, When the pointer on the pressure gauge drops to 5 kg/cm2, it can no longer be used.

The correct method of oxygen inhalation is to turn on the oxygen generator, select the appropriate oxygen concentration, and pay attention to atomizing and moisturizing inhalation. The precautions are to observe the effect of oxygen therapy and avoid catheter blockage or pollution.

1. Correct way of oxygen inhalation:

The correct way of oxygen inhalation is to turn on the oxygen generator, select the appropriate oxygen concentration, and pay attention to atomizing and moisturizing inhalation. The specific steps of oxygen inhalation are to plug in the power supply and turn on the oxygen generator to adjust the oxygen inhalation flow. Generally, the oxygen inhalation concentration is about 1-2 liters, but the requirements are different according to different conditions. The specific oxygen inhalation concentration should be selected under the guidance of doctors. For example, patients with chronic obstructive pulmonary disease need to adjust it below 3 liters; For patients with pneumothorax, pulmonary interstitial fibrosis and bronchial asthma, more than 3 liters of oxygen can be given, but the oxygen flow rate should not be too high to prevent long-term high-flow oxygen inhalation.

2. Precautions:

Pay close attention to the effect of oxygen therapy during oxygen inhalation. If the symptoms such as dyspnea are relieved or relieved, and the heartbeat is normal or close to normal, it indicates that oxygen therapy is effective. Otherwise, the doctor should be informed to find the reason and deal with it in time. It is also necessary to pay attention to the fact that high concentration oxygen inhalation should not take too long. It is generally believed that the oxygen inhalation concentration >; 6%, lasting more than 25 hours, oxygen poisoning may occur. At the same time, attention should also be paid to prevent pollution and catheter blockage, and nasal congestion, oxygen delivery catheter, humidification heating device, ventilator pipeline system, etc. should be replaced regularly and cleaned and disinfected to prevent cross-infection. Oxygen inhalation catheter and nasal obstruction should be checked for secretion blockage at any time and replaced in time to ensure effective and safe oxygen therapy.
