What information can be gathered from the following mechanical ventilator waveform?   I. Peak inspiratory pressure II. Inspiratory time III. Exhaled tidal volume IV. Inhaled tidal volume

A patient has the following blood gas results:   pH – 7.34 FIO2 – 35% PaCO2 – 40 torr Respiratory rate – 32 breaths/min PaO2 – 75 torr HR – 110 bpm HCO3 – 29 mEq/L BP 145/85 mmHg BE – +4 SpO2 – 91% Hb – 13 g/dl PETCO2 – 25 torr   What is the patient’s VD/VT?

An adult male patient is intubated with a 7.5 ETT. Current settings are as follows   Mode – AC/VC Total Rate – 15 breaths/min Rate – 15 breaths/min PIP – 10 cm H2O VT – 500 ml Exhaled VT – 300 ml PEEP – 10 cm H2O SpO2 – 85% FIO2 – 1.0   What should the therapist do?

A patient is in the ICU intubated due to metabolic acidosis and respiratory muscle fatigue: pH – 6.98 WBC – 9,500 PaCO2 – 30 torr Hct – 42% PaO2 – 98 torr  Hb – 14 g/dl HCO3 – 10 mEq/L Plt – 250 SaO2 – 97% Glucose – 850 g/dl Which of the following would you recommend based on these results?

A patient is receiving CMV in the AC/PC mode with the following parameters. The patient has a back up rate of 12 breaths/min  and an inspiratory time of 1 second. What is the I:E ratio

What are signs that a patient’s inspiratory flow demands are not being met on ventilatory support?   I. Increased accessory muscle use II. Ventilatory muscle atrophy III. Chest retractions IV. Tachypnea

A patient in respiratory failure secondary to asthma bronchitis is on ventilatory support with the following information:   Mode – AC/VC PIP – 35 cm H2O Rate – 15 breaths/min Total rate – 15 breaths/min VT – 500 ml VE – 6 L/min PEEP – 3 cm H2O I:E – 1:3 FIO2 – 0.50 PIF – 30 LPM   The patients chest radiograph suggest flattened diaphragm and increased intercostal spaces. What should be done at this time?

A physician wants to wean a patient that is currently on APRV. How is weaning accomplished on this mode of ventilation?

A patient has an arterial line and the respiratory care practitioner raised the bed to draw from the line for an ABG sample.  The patient’s arterial line site is now higher than the transducer for the A-Line. How will this effect the A-line reading?

A patient on ventilatory support has the following flow vs. time waveform: Assessment of this waveform reveals:
