Which of the following ventilator heater temperatures below meet the optimum humidity requirement? 

   You are at the bedside of a ventilated patient and notice that the low pressure alarm is sounding. Which of the following below is likely the cause? .

A patient with ventilatory failure secondary to muscle fatigue is placed on mechanical ventilation. The physician wants to rest the patient on ventilatory support and then ease into a trial run of partial support, followed by weaning. Choose the modes in sequence, from most to least ventilatory support that you would use.

Calculate the total minute ventilation given the following information: AC Mode FiO2 .40 Vt 600ml Rate 12 Patient’s Respiratory Rate 20

The respiratory therapist is preparing to extubate a patient. The patient should be told the tube will be removed  

A patient with decreasing lung compliance is being ventilated with a pressure-cycled ventilator. In order to assure adequate ventilation, you would monitor the patient’s

Mechanical ventilation is initiated with a pressure support of 10 cm H2O and a CPAP of 5. There is not a mandatory rate set.  Which of the following parameters would a therapist monitor in order to determine that the pressure support level is adequate?

The following measurement were obtained and shown on the ventilator flowsheet: 0700     Vt = 500 ml     PIP 25     Plateau     20 1000     Vt = 500 ml     PIP 28     Plateau     20 1300     Vt = 500 ml     PIP 33     Plateau     20 Based on these measurements what is most likely occuring?

In a pressure mode of ventilation the flow- time waveform will be  ___________________.

Based on the Oxyhemoglobin Dissociation Curve, when the SpO2 is 90% the PaO2 should be  ____________.
