The effectiveness of the new ventilation device (NVE) in endexpiratory oxygenation and carbon dioxide during blepharoplasty surgery: a clinical trial

The covering of the patient's face during eye surgery, including blepharoplasty, despite receiving oxygen, due to the presence of a closed space, the release of carbon dioxide is disturbed and the possibility of re-breathing increases. A new ventilator was designed to solve this problem. During local head and neck and eye surgery, where the patient's head, face, and airway are covered by a cloth, this device facilitates the elimination of exhaled carbon dioxide and prevents the effects of hypoxemia and hypercapnia, such as headache, increased blood pressure, and drowsiness. Severe and reduced level of consciousness that leads to tachypnea and cardiac arrhythmia, which all lead to the patient's non-cooperation with the surgeon, prevents and reduces treatment costs.
