measures encompass adjusting PEEP and tidal volume, utilizing high-frequency oscillatory ventilation, or even resorting to extracorporeal membrane oxygenation. ●​ Cardiovascular Complications : Reduced cardiac output, venous return, and myocardial blood flow are possible cardiovascular concerns. Addressing these issues may involve increasing circulating volume or administering nitrogen-oxygen mixtures or carbon dioxide as necessary. ●​ Oxygen Toxicity : This occurs when the oxygen concentration is excessively high during supplementation therapy. Monitoring arterial blood gases and maintaining PaO2 within appropriate levels (50-60) is key to preventing this. ●​ Denitrogenation Absorption Atelectasis : This results from the elimination of nitrogen from the body tissues and lungs, which can happen with oxygen concentrations exceeding 80%. ●​ Hypoventilation : This can occur due to inadvertent extubation or disconnection from the ventilator. Preventive measures include using low-pressure and disconnect safety alarms and ensuring careful handling of tubing and artificial airways during client movement or transport. ●​ Hyperventilation : This may be caused by sensitivity setting defects, respiratory secretions, ventilator autocycling due to system leaks, or neonatal surfactant administration. Monitoring flow volumes, pressure, and resistance aids in managing these issues. ●​ Hospital-Acquired Ventilator Infections : Pneumonia and other respiratory infections are common concerns. Rigorous adherence to infection control measures, such as handwashing, standard precautions, aseptic procedures, and sterile suctioning procedures, minimizes the risk. ●​ Ventilator-Related Airway Complications : Trauma to vocal cords, airway obstructions (e.g., mucus plugs, kinked tubing), tracheal trauma, glottis injuries, and other airway-related problems necessitate close monitoring and immediate intervention. ●​ Other Complications : Mechanical ventilation can lead to additional complications such as renal impairment, fluid retention, increased intracranial pressure, periventricular leukomalacia, and intraventricular hemorrhage. Nurses play a pivotal role in ensuring effective ventilator management. By diligently assessing clients, closely monitoring ventilation parameters , and promptly addressing any complications , nurses safeguard the well-being of ventilated individuals . This meticulous care enables clients to derive the maximum benefit from mechanical ventilation, ultimately contributing to their overall health and recovery. Assessing and Managing Respiratory Function In addition to assessing the client's arterial blood gases and symptoms of impaired ventilation and oxygenation, various tests and measurements can provide valuable data related to respiratory functioning:
