A patient is receiving non-invasive positive pressure ventilation.  Pulmonary compliance has decreased over the last 4 hour.  To increase the patient’s tidal volume, it would be best to make which of the following changes?

You’re completing a vent check and patient assessement on your COPD with pneumonia. You auscultate expiratory wheezes bilaterally and diminished breath sounds in the lower lobes. Peak pressures are climbing and there’s a 150ml difference in your inspriatory and expiratory tidal volumes. Which waveform would you assess on the ventilator to confirm the current air trapping?

Across the United States, about 1 in 2950 babies are diagnosed with cystic fibrosis (CF) at birth. The C allele is dominant over c, and homozygous recessive individuals (cc) have the disease.  Calculate the frequency of the CC (no cystic fibrosis) genotype.
