An intubated, mechanically ventilated neonate developed a pneumothorax of the right lung. What could the respiratory therapist recommend to help the injured lung to heal?

How does optimal PEEP differ from PEEP that delivers the best PaO2?

A 5-foot, 6-inch, 143-lb (65-kg) teenager had a cut on his lower leg. Now he is in the ICU with a temperature of 103°F, blood pressure of 80/50 mm Hg, heart rate of 120 beats/min, and SpO2 of 88% on 100% oxygen. His pulmonary capillary wedge pressure is 14 mm Hg, and cardiac output is 8 L/min. Breath sounds reveal coarse crackles throughout the lungs, and his bronchoalveolar lavage fluid contains a very high protein level. The patient is intubated and currently is being ventilated with a tidal volume of 800 ml, frequency of 14, and PEEP of 0.

     The equation of motion of a particle is                                            s = t3 –  4t2 + 2t + 8                                                               where s is in meters                                                               and  t is in seconds. Find the acceleration  after t = 90 seconds.
