In the clinical scenario where a tracheostomy patient receiving 35% O2​ via a T tube experiences a drop in SpO2​, the RT finds that aerosol mist is not visible at the T tube throughout inspiration and condensate is obstructing the large-bore tubing. What is the immediate result of this obstruction?

Absorption atelectasis can occur rapidly when patients are breathing 100% O2​. This occurs because the gas pressure gradient between the obstructed alveoli and the mixed venous blood (pulmonary artery) is extremely large, causing rapid oxygen diffusion. In this specific scenario (breathing 100% O2 in an obstructed alveoli), what is the approximate total gas pressure listed for the pulmonary artery?

A disoriented postoperative patient exhibits clinical signs of hypoxemia, including tachypnea, tachycardia, and mild cyanosis. However, the respiratory therapist (RT) measures the patient’s oxyhemoglobin saturation via pulse oximetry at 91%. What is the recommended course of action in this situation of conflicting assessment information?
