A patient is receiving continuous mechanical ventilation following an MVA.  Upon entering the room, the respiratory therapist notes the following:HR 123 bpmSpO2 76%BP 78/49Patient is diaphoretic and ashenWhat should be the first action the respiratory therapist takes?

One hour after initiating mechanical ventilaiton VC-CMV, the repiratory therapist notes the patient’s PIP has changed from 45 cmH2O to 60 cmH2O and the plateau pressure has changed from 35 cmH2O to 38 cmH2O.  Which of the following should the therapist recommned?

A postoperative patient complaining of dyspnea is found to have tachypnea and tachycardia, and is somewhat confused. Breath sounds reveal end inspiratory crackles in both lung bases. An arterial blood gas (ABG) is drawn and reveals the following: pH 7.48; PaCO2 30 mm Hg; PaO2 51 mm Hg; SaO2 87%; HCO3- 22 mEq/L while on a 30% air entrainment mask. The most appropriate respiratory therapy intervention includes which of the following?

If the set VT is 500 mL, using the following diagram:  the PIP is cmH2O, the Pplat is cmH2O, the Raw is cmH2O/L/sec, the PEEP is cmH2O, and the Cstat is mL/cmH2O.

The movement of air in and out of the lung is .

A mechanically ventilated patient is going to be placed on pressure support ventilation following an acceptable spontaneous weaning trial. The patient is a 5’9″ male who weighs 185 lb. During volume-controlled continuous mandatory ventilation (VC-CMV) his average peak inspiratory pressure (PIP) was about 26 cm H2O and the plateau pressure (PPlateau) was 11 cm H2O. What initial pressure support level should be set?

In the simplest of terms, a is required for air to flow from the mouth to the alveoli.

Which of the following four adult patients receiving ventilatory support is the best candidate for weaning?    VC    VE     MVV    MIF      VD/VT
