Background
Prone position ventilation refers to natural breathing or mechanical ventilation of a patient in prone position, and is commonly used for treating severe pneumonia, pulmonary edema and other patients. The lungs of patients with severe pneumonia or pulmonary edema can have massive inflammatory exudation, resulting in pulmonary stuffiness changes in alveolar filling fluid; at this time, only a small amount of alveoli can exchange gas with surrounding pulmonary capillaries to complete ventilation in the place where the lung has actual change, and the actual change part of the lung and the distribution of ventilation parts are uneven, so that the actual change part of the patient cannot normally ventilate when the patient ventilates in the supine position, and only after repeated posture change (from the supine position to the prone position) is performed, the liquid in the lung can be dispersed to the inflated part under the action of gravity, and the part of the lung which is inflated after ventilation is given is increased, so that the ventilation effect is improved, and the hypoxia symptom is relieved. In addition, the prone position ventilation can also enable the lung to be relatively low in the chest by changing the body position of a patient, so that lung tissues are more easily expanded, the ventilation function of the lung is improved, and secretion in the airway is conveniently discharged.
When ventilation is carried out in the prone position, medical staff need to closely monitor vital signs such as heart rate, blood pressure, blood oxygen saturation and the like of a patient, and the facial and arm postures of the patient are replaced every two hours, so that choking and pressure sores are avoided. At present, when nursing a patient for prone position ventilation, medical staff mainly fills up pressure sore prevention pads on the face, the arms and the hips of the patient, and fills up a hard frame on the chest of the patient so as to lift the chest, and the frame is of a hollow structure, so that the chest compression can be reduced as much as possible. However, the existing complete equipment which is not specially used for supporting the prone position of the patient often uses articles such as a quilt, a pillow and the like for folding and self-making by medical staff; when in use, the position is difficult to control and fix, and the head and the face of a patient are inconvenient to observe; in addition, for the patient with trachea cannula, self-made device not only does not have the through-hole that trachea cannula can pass, but also inconvenient inclination when supporting the patient according to the use needs is adjusted, causes the patient to be pressed in same position for a long time, very easily forms pressure sore.
