The pulse oxygen supply and direct oxygen supply mode how to choose?
At present, there are various opinions on the main differences between pulse oxygen supply and direct oxygen supply, which leads to problems in the selection of hypoxic people. This article will describe the difference between the two in detail:
One: the principle of pulse oxygen supply
Pulse oxygen supply is to provide additional oxygen on a stable basis through pulse technology, so as to achieve hypoxia treatment during respiration. Compared with traditional oxygen therapy, pulsed oxygen supply takes advantage of the self-transmission characteristics of oxygen in the blood, reduces the pressure of red blood cells in the capillary bed, and is more suitable for high-flow oxygen delivery. This method of oxygen supply can reduce oxygen waste, but also reduce the irritation of the nasal mucosa caused by oxygen pressure and fluctuations.
The pulsed oxygen supply uses intelligent control technology to adjust the oxygen concentration and flow according to the patient's inspiratory needs and activity level, so as to achieve the best treatment results. This method can combine the oxygen supplier with the ventilator, making the oxygen delivery process safer and more reliable, but also more energy saving.
In addition, pulsed oxygen can reduce carbon dioxide retention, reduce the incidence of complications, for asthma and emphysema and other respiratory disease patients, there is a good therapeutic effect. At the same time, pulsed oxygen supply is more flexible and applicable, which can meet the treatment needs of patients in different scenarios.
Two: The difference between pulse oxygen supply and direct oxygen supply
Operating mode : Direct oxygen supply mode means that the machine continues to output oxygen regardless of whether the user inhales, while the pulse oxygen supply mode supplies oxygen according to the user's breathing rate. It can prepare for oxygen supply at the end of expiratory period, supply oxygen at the moment of inhalation, and suspend oxygen supply when exhaling. In this way, human respiration can be accurately sensed, and impact resistance can be reduced, which is equivalent to free breathing, thus improving the oxygen utilization rate.
Oxygen utilization rate : Because the direct oxygen mode still provides oxygen when the user exhales, and the oxygen cannot enter the body at this time, the oxygen utilization rate is relatively low. In contrast, the pulse oxygen mode has a higher oxygen utilization rate because it is able to deliver oxygen at the right time, that is, when the user inhales, thereby improving the efficient use of oxygen.
Application scenario : The direct oxygen supply mode is mostly used in desktop oxygen generators, which are usually used at home or piped oxygen is used in hospitals. These oxygen generators are usually large, need to be plugged in, and have poor mobility. The pulse oxygen supply mode is mostly used in portable oxygen generators, which consumes less power and can extend the battery use time, and is suitable for going out to mobile oxygen supply to meet the oxygen supply needs of outdoor activities, plateau mountaineering tourism, driving tourism and other mobile scenes.
comfort : The direct oxygen mode may dry the nostrils for a long time. It is necessary to moisten the oxygen with water to alleviate the problem of drying out the air. Because the pulse oxygen supply mode can provide oxygen intelligently according to the respiratory rate, it avoids excessive oxygen supply, saves oxygen consumption and reduces treatment costs, and also reduces the stimulation of air flow to the nasal cavity, making oxygen inhalation more comfortable.
To sum up, the pulse oxygen supply mode has obvious advantages compared with the direct oxygen supply mode in improving the oxygen utilization rate, increasing the comfort level and adapting to different use scenarios. We can comprehensively consider our own characteristics and make reasonable choices when choosing.
