Oxygen therapy precautions for chronic pulmonary heart disease

Nov 30, 2018

Oxygen therapy is extremely important for patients with chronic pulmonary heart disease. During the process of oxygen inhalation, the following issues should be noted:

Oxygen therapy needs attention
(1) Concentration and flow rate of oxygen absorption: generally low concentration (24% to 28%), low flow rate (1.0 to 2.0 L/min), continuous oxygen supply.
(2) Index control during continuous oxygen therapy: continuous application of oxygen for 24 hours can not be interrupted,
When PaO2 rises above 8.0 kPa (60 mmHg), PaCO2 drops below 6.7 kPa (50 mmHg) and can be intermittently oxygenated for several days. If PaO2 does not fall any more, PaCO2 will no longer rise before oxygen therapy can be stopped.
(3) Temperature and humidity of oxygen: The temperature of oxygen inhaled should be maintained at 37 ° C, and the humidity is about 80%.
4) oxygen route: nasal tube method, nasal congestion method is better.
(5) Stop oxygen therapy indicators: stable breathing, heart rhythm rules, heart rate slowing, normal blood pressure, conscious, good spirits, lips and nail bed disappeared, PaO2>8.0kPa no longer decreased after oxygen withdrawal, PaCO2<6.7kPa Stop rising and stop oxygen. It is worth noting that intermittent oxygen inhalation should be observed for several days before stopping oxygen inhalation before oxygen can be stopped.


2. Monitoring during oxygen therapy
The monitoring during oxygen therapy should pay attention to the following aspects:
* Timed detection records body temperature, pulse, respiration, heart rate, blood pressure;
* Observe cough, cough, cyanosis, and change of mind;
* Oxygen supply equipment is disinfected regularly before use and during use;
* Always check for oxygen flow and oxygen flow;
* Prevent oxygen poisoning. Chronic pulmonary heart disease should pay attention to oxygenation while avoiding various predisposing factors, keeping warm and preventing respiratory infections. Proper breathing exercise can help improve respiratory defense function.
The above suggestions should be carried out under the guidance of a doctor.
