The RT hears a low pressure alarm on a patient receiving ventilatory support. She evaluates the patient and finds that the individual is not in distress and is being ventilated and oxygenated. She checks the activated alarm (low Ve), silences it, and saves the graphics display. What do these waveforms indicate?

A 17-year-old student complained of wheezing and shortness of breath, especially at night. He was known to be allergic to feathers and house dust. Physical examination revealed inspiratory and expiratory rales and hyperresonance with percussion of the chest but no cyanosis. Radiologic examination suggested over-inflation of the lungs, but no localized disease. The following laboratory and pulmonary function test values were obtained: Vital Capacity: 2,800 ml (decreased) Functional Residual Capacity: 4,420 ml (increased) Total Lung Capacity: 7,050 ml (normal) Tidal Volume: 600 ml (normal) Respiratory Rate: 16 breaths/minute (increased) Arterial PO2: 62 mmHg Arterial O2 saturation: 90% Arterial O2 saturation (breathing 100% oxygen): 100% Arterial pCO2: 38 mmHg Arterial Blood pH: 7.44 Maximum voluntary ventilation: 60 L/min (decreased) Maximum inspiratory flow rate: 220 L/min Maximum expiratory flow rate: 50 L/min Why is the pCO2 normal?
