A 45-year-old male who is 160 cm (5 ft 2 in) tall and weighs 80 kg (175 lb) is brought to the ED following a Stab wound. PC, A/C ventilation is initiated.  One days later, ventilator settings are: FIO2 0.40   pH 7.31 Mandatory rate 14   PCO2 49 mm Hg Insp Press 16 cmH2O   PO2 76 mm Hg VT 420 mL   HCO3- 23 mEq/L PEEP 5 cm H2O   BE -2 mEq/L       SaO2 (calc) 93% Which of the following should a respiratory therapist recommend FIRST?

  What type of flow waveform does A represent?

A 189-cm (6-ft 2-in), 92-kg (202-lb), 32-year-old male was injured in a motor vehicle crash. She is intubated at the scene with a 6.0-mm ID endotracheal tube. On arrival to the ED, PC, A/C ventilation is initiated, and the following data are noted: FIO2 0.40   PEEP 5 cm H2O Mandatory rate 12   PIP 40 cm H2O VT 525 mL   Pplat 22 cm H2O Inspiratory flow 55 L/min       The patient is exhibiting increased work of breathing, and is breathing dyssynchronously with the ventilator. A respiratory therapist should recommend

  What type of flow waveform does E represent?

A 59-year-old man who is 170 cm (5 ft 7 in) tall and weighs 65 kg (143 lb) is receiving VC ventilation after abdominal surgery. Ventilator settings and blood gas analysis results are: FIO2 0.40   pH 7.47 Mandatory rate 14   PaCO2 31 mm Hg Total rate 14   PaO2 117 mm Hg VT 500 mL   HCO3- 23 mEq/L       BE 0 mEq/L       SaO2 (calc) 98% A respiratory therapist should

Patient’s RR is 20 breaths/min, PaCO2 is 30 mm Hg. If a PaCO2 of 40 were desired, the RR be set at what value?  

This VILI is cause from the sheer constant forces of opening and closing of the alveoli leading to damage? 

A 47-year-old female who is 155 cm (5 ft 2 iin) tall and weighs 70 kg (155 lb) is receiving PC A/C ventilation after abdominal surgery.
