List the potential locations for patients requiring long-term ventilatory care in order of cost from most expensive to least expensive.1. Patient’s home2. Long-term acute care facility3. Intensive care or acute care unit4. Extended care facility

A patient with a tracheostomy tube (TT) is being discharged home with a ventilator, which he uses only during the night, without supplemental oxygen. During the day he uses a speaking valve. Which of the following equipment must he have in his home?1. Suctioning equipment2. Oxygen concentrator3. Second mechanical ventilator4. Manual resuscitator bag

The flow–time curve shows small oscillations after the peak flow rate has been reached. The respiratory therapist can alleviate this by making which of the following ventilator adjustments?

While performing a patient-ventilator check, the respiratory therapist notes that the patient suddenly develops signs of severe respiratory distress. The low O2 saturation alarm on the pulse oximeter activates. Breath sounds are equal bilaterally with no change from previous findings. The respiratory therapist disconnects the patient and performs manual ventilation using 100% O2. A suction catheter passes through the patient’s ET without difficulty; however, the patient’s distress continues and O2 saturation remains low. The therapist notes that the capnometer reading for PetCO2 has changed from its previous value of 35 mm Hg to 27 mm Hg. Arterial blood gas analysis indicates that the PaCO2 has not changed but the PaO2 decreased to 20 mm Hg. The P(a–et)CO2 has increased from 6 to 14 mm Hg. What is the cause of the patient’s respiratory distress?
