In the use of home non-invasive ventilator, there are often problems such as patient intolerance and poor effect. In fact, the operation details of the use of the home noninvasive ventilator are often more important.
Today, the editor will introduce the misunderstandings that are easy to ignore in the use of household non-invasive ventilators, and provide a little experience for every user or beginner.
Myth 1: Turn on the air first, then wear a mask.
Many operators put on domestic ventilators for patients, often in the order of first turning on the machine for air supply and then putting on masks for patients. However, little imagine, turning on the machine for air blowing will cause the baseline calculated by the machine to drift seriously, giving full play to the air leakage compensation function of the ventilator. The large amount of air leakage compensation is far higher than the actual air leakage. Patients feel that the air flow is large, relatively rushed and intolerable, which is an important cause of the failure.
Therefore, the correct approach is the home ventilator in the standby state, first wear a mask, and then connect the ventilator line immediately after the ventilator ventilation.
Myth 2: Patients with obvious dyspnea can use home non-invasive ventilator
Many people mistakenly believe that only patients with obvious dyspnea are the indications for non-invasive ventilator treatment. In fact, non-invasive ventilator is mainly used for patients with mild to moderate respiratory failure, not mainly for those who have already had severe respiratory failure.
Because when patients have abnormal respiratory function, such as hypoxia, the organs and cells of the whole body may suffer a series of pathophysiological changes and damage. Timely and active intervention in the early stage of respiratory failure can effectively block the damage, prevent the degree of respiratory failure from worsening, improve the success rate of treatment, and bring greater benefits and significance.
Therefore, the noninvasive ventilator should be used as soon as possible, rather than waiting until the patient has developed obvious respiratory failure. In this way, the best time for noninvasive ventilation is often lost, resulting in delay or failure of treatment.
Misunderstanding 3: use during the day, not at night
Many people think that not only patients or their families, but also some clinical medical staff think that non-invasive ventilators can be used during the day and patients should have a good rest at night. In fact, after patients fall asleep at night, the respiratory center is more likely to be inhibited, and respiratory metabolic problems will be more serious, especially in patients with carbon dioxide retention or obstructive nocturnal hypopnea syndrome.
Therefore, patients need more non-invasive ventilator treatment at night, which brings more benefits and help. Moreover, in terms of ventilator parameter adjustment, the pressure difference needs to be larger and EPAP should be relatively larger to relieve the obstruction of upper airway.
Myth 4: After the machine, the patient is uncomfortable and immediately stop using it.
In fact, anyone wearing a mask is uncomfortable to breathe, especially when using it for the first time. The essence that can really make patients feel comfortable breathing is the improvement of the condition.
Before using a home ventilator, you need to do a good job of thinking and explain to the patient the purpose, necessity and importance of home non-invasive ventilator treatment, especially the benefits of home non-invasive ventilator treatment, and the possibility of discomfort during ventilator treatment, especially to remind the discomfort at the beginning of the machine and not to give up easily, so as to let the patient understand the non-invasive ventilator and eliminate tension, panic and resistance, help patients to improve treatment compliance and confidence.
In the process of using non-invasive ventilator, the ventilator pressure parameters and oxygen concentration can be adjusted according to the tidal volume, respiratory waveform, blood oxygen saturation and so on. Observe if the patient's breathing rate is improved in a short period of time while the blood oxygen rises, then, often after reasonable treatment, with the improvement of breathing disorders, the patient will feel comfortable after 20 minutes.
Myth 5: Increasing the suction pressure will make the user intolerant
The real causes of user intolerance are:
1. The synchronization of the machine is not good, resulting in more effort for users.
2. The air leakage is too large, resulting in large airflow in the mask, causing the user to reflect that the wind is too large.
3. The pressure difference is seriously insufficient, and the machine fails to effectively assist the patient to breathe, resulting in the patient still feeling stuffy.
Therefore, in addition to normal air leakage, avoiding abnormal air leakage, referring to the ventilator tidal volume, increasing the pressure difference is the key to effectively assist breathing.
Myth 6: The tighter the nose mask or mouth and nose mask, the better
It is true that when the non-invasive ventilator blows air to the patient's respiratory tract, if the mask leaks, it will definitely affect the effect. So the tightness of the headband control in what degree is more appropriate?
Generally speaking, it is appropriate to adjust the tightness of the headband to be able to fit 1-2 fingers. Too tight headband is easy to cause excessive facial pressure, affect blood circulation and lead to pressure sores on the nose and face. Too loose headband leads to excessive air leakage before affecting the therapeutic effect.
