Endotracheal intubation is frequently needed for supportive therapy in the management of inhalation injury. Most pertinent piece of information in evaluating a patient's ventilatory status? Ventilation is the movement of air in and out of the lungs through a patent airway. The majority of observations regarding ventilation focus on the movements of the chest. SIGNS OF ADEQUATE VENTILATION: In most patients, your assessment of ventilation will be based on observing their respiratory rate (normal 12 to 20) and listening for clear breathing sounds in the left and right chest. Auditory confirmation of breathing sounds is the strongest sign of adequate ventilation. In patients on ventilators or bag-valve mask, this does not change. Most pertinent piece of information in evaluating a patient's oxygenation status? Oxygenation is the delivery of oxygen to the tissues of the body, poor ventilation or respiration will generally lead to poor oxygenation. Loss of oxygenation is the ultimate result of ventilatory or respiratory failure. You need to observe the patient's mental status, skin color, oral mucosa, and check a pulse oximeter. Mental status is either normal or abnormal, assessing mental status is based on asking questions about who the person is, what time/date it is, where they are, and why they are here. Skin and mucosal color are important indicators of oxygenation. Just as with poor respiration, cyanosis, pallor, or mottling are signs of decreased oxygen delivery. Pulse oximetry level is the most objective measure of oxygenation, it reads the saturation of hemoglobin (reported as SPO2), note that a pulse oximeter is not foolproof. A patient with poor oxygenation in the limbs may have sufficient oxygenation to their core or vise-versa. Pulse oximeters can also be fooled by specific toxic gases. Always ensure that you match up your pulse oximetry readings with physical findings and ensure they support one another. Pulse oximeters are imperfect and are not a real-time measure of O2 saturation
