Oxygen therapy is a method of treating new pneumonia. A medical ventilator is the main means of oxygen therapy.
(1) Standard oxygen therapy: severe patients should receive oxygen inhalation with a nasal cannula or mask, and promptly assess whether respiratory distress and (or) hypoxemia is relieved.
(2) High-flow nasal catheter oxygen therapy or non-invasive mechanical ventilation: when the patient's respiratory distress and/or hypoxemia cannot be relieved after receiving standard oxygen therapy, oxygen therapy by HFNC machine or non-invasive ventilation can be considered. It is emphasized that "if there is no improvement or even deterioration within a short period of time (1 to 2 hours), tracheal intubation and invasive mechanical ventilation should be performed in time."
(3) Invasive mechanical ventilation: use lung protective ventilation strategy, namely small tidal volume (4~8mL/kg ideal body weight) and low inspiratory pressure (platform pressure <30cmH20) for mechanical ventilation to reduce ventilator-related lung injury. Many patients have asynchrony between man and machine, so sedation and muscle relaxants should be used in time.
(4) Rescue treatment: for patients with severe ARDS, recruitment is recommended. In the case of sufficient human resources, prone ventilation should be performed for more than 12 hours a day. If the effect of prone position ventilation is not good, extracorporeal membrane oxygenation (ECMO) should be considered as soon as possible.
Among them, non-invasive or invasive mechanical ventilation involves the use of medical ventilators, which are mainly used in ICU wards. Pigeon Medical can provide different kinds of medical apparatus. Welcome to consult and purchase!
Some patients with severe acute respiratory infections (such as SARS, MERS, influenza, new coronavirus, etc.) can progress to acute respiratory failure. Among them, critically ill patients need different levels of respiratory support treatment.
Among the recommended prevention and control measures for hospital infection, although the negative pressure single ward has been the first recommendation, it is difficult to achieve in actual work. Strictly wearing personal protective equipment (PPE) is something we can do but is easily overlooked. Medical staff should pay attention to the possibility of exposure to aerosols during diagnosis as well as treatment activities around noninvasively ventilated patients, and it is recommended to upgrade protective measures. The requirement of endotracheal intubation treatment for ward is strict. The precondition of endotracheal intubation is laminar flow ward, and medical staff need to be equipped with 2 to 3 after intubation.
In the current treatment of COVID-19, if the intubation treatment is directly carried out without a corresponding laminar flow ward, the patient will spray aerosols containing the new coronavirus, which will increase the risk of infection for medical staff. In addition, central respiratory failure caused by brain inflammation, trauma, tumor, cerebrovascular accident, drug poisoning, severe chest disease or respiratory muscle weakness, cardiopulmonary resuscitation and so on are all suitable for supportive treatment using medical ventilator.
