1. Ventilators are for critically ill patients
Many patients and their families believe that there is no need to use ventilators as a last resort. Non-invasive ventilators are mainly used for patients with mild to moderate respiratory failure, not mainly for those who have already experienced severe respiratory failure. In life, once respiratory failure has become apparent, the best time to use the machine is often missed and the treatment effect will be greatly reduced. Home ventilators have been widely used in the treatment of sleep apnea, slow obstructive pulmonary, call failure and other common chronic diseases, and are not only used to rescue patients with serious illness, for those patients who have developed ventilator indications, the earlier the application the better.
2. Use during the day and rest naturally at night
The purpose of patients using a non-invasive ventilator is to relieve airway obstruction. In fact, when patients fall asleep at night, their respiratory center is more likely to be inhibited and respiratory metabolic problems can be more severe, especially in patients with combined carbon dioxide retention or obstructive nocturnal hypoventilation apnea syndrome. In patients on noninvasive ventilators, the goal is to relieve airway obstruction. To relieve the obstruction of the upper airway in patients who fall asleep at night, the need for adjunctive therapy using a noninvasive ventilator at night is even greater.
3. How soon to use the ventilator after eating
Many patients, especially the elderly, do not pay attention to the relationship between the ventilator and diet, and always use the ventilator not long after eating, which can easily lead to nausea, vomiting and other adverse reactions, resulting in misaspiration. Before doing non-invasive ventilator treatment, you should avoid eating too much, and if there are no special circumstances, it is recommended to use the non-invasive ventilator at least 30 minutes to 1 hour after eating.
4. The use of ventilators can damage lung function
Only when your airway collapses at night, the machine will open the collapsed airway by rising pressure, so the sleep ventilator will not interfere with your voluntary breathing, so there is no such thing as damage to your lung function. COPD patients with chronic obstructive pulmonary disease do not use bi-level ventilators to damage lung function, because COPD patients with chronic obstructive pulmonary disease lose elasticity due to alveolar obstruction, and the carbon dioxide in the body can not be discharged, resulting in carbon dioxide retention. Therefore, the use of bi-level ventilators for COPD patients with chronic obstructive pulmonary disease will not only not damage the lung function, but also help patients recover and improve the quality of life as soon as possible.
5. Wearing a ventilator can be dependent
We take snoring patients, some people use the ventilator after a period of time, without the ventilator does have the phenomenon of bad sleep, in fact, this is related to the previous use of the ventilator to help him solve the sleep apnea at night, so sleep is better; and the ventilator is to treat sleep apnea in a physical way, when later without the ventilator, he will have the phenomenon of bad sleep at night will also recur. Then there are copd slow obstructive pulmonary patients, because copd slow obstructive pulmonary is a progressive disease, there is no drug to cure this disease, so the disease will only get more and more serious, and the ventilator is to help him eliminate carbon dioxide in the body, so the ventilator will only be beneficial to its condition, there is no harm, when a period of time after not using the patient's body carbon dioxide rises, there will be shortness of breath, wheezing, coughing This is not caused by the ventilator, it is caused by the development of the disease, so the ventilator itself is not dependent.
6. The tighter the mask, the better
When the non-invasive ventilator blows air into the patient's airway, if the mask leaks, it will definitely affect the effect. So what is the appropriate level of headband tightness control? Generally speaking, the tightness of the headband should be adjusted to fit 1-2 fingers. Too tight a headband can easily cause excessive pressure on the face, affecting blood circulation and leading to nasal and facial pressure sores. The headband is too loose leading to excessive air leakage before the treatment effect is affected. Because when wearing the machine, the mask will cover the nose and mouth at the same time, it is also believed that if there is a sudden power failure at night, or if the respirator itself malfunctions, it may cause asphyxiation. However, you can rest assured that the mask is equipped with an anti-asphyxiation device and many air vents, so this situation will not occur.
