Mech Vent Kettering
| Question | Answer |
|---|---|
| A 44 year-old patient with ARDS receives mechanical ventilation in the Pulmonary ICU at the following settings: Mode: PC, A/C Peak Pressure: 36 cm H2O Plateau Pressure: 30 cm H2O Mandatory Rate: 18/min Total Rate: 20/min FIO2: 0.85 PEEP: 12 cm H2O | Prone Position, They have ARDS |
| 52-year-old, 5' 9" tall male patient weighing 85 kg (187 lb) is being MV An ABG Assist/Control FIO2: 0.40 Mandatory rate: 10 Total rate: 10 VT: 650 mL PEEP: 5 cm H20 Mechanical VD: 100 mL pH: 7.28 PaCO2: 74 torr PaO2: 57 torr SaO2: 86% HCO3-: 23 mEq/L | Decrease Deadspace, to Drop PACO2 |
| Alveolar Ventilation deals with what? | Its the Change in tidal volume and rate |
| What determines if a patient is developing ventilatory failure? | ABG |
| What determines good blood perfusion? | B/P |
| What determines oxygen carrying ability of the blood? | Hematocrit |
| pH: 7.40 PaO2: 96 torr PaCO2: 43 torr SaO2: 94% The patient's current ventilator settings are: Tidal volume 650 mL, SIMV mandatory rate 4 /min, PEEP 5 cm H2O, and FIO2 0.35 even though she is not fully conscious. | Place on CPAP at Fio2 45%, Not conscious but we want to wean her off on her own from the vent not yet extubating them though |
| A 5' 10", 80 kg (176 lbs) male, MVA has developed ARDS Mode: VC, SIMV VT: 500 mL Set Rate: 14 br/min. FIO2: 0.60 PEEP: 12 cm H2O pH: 7.35 PaO2: 72 torr PaCO2: 44 torr SpO2: 93% The patient is conscious and pulling on the IV lines and ventilator tubing. | Sedate patient, ABG is good and Changing Mode wont do much and the patient does seem agitated so sedating the patient is the best answer |
| A 78-year-old male patient is being treated for obstructive sleep apnea with BIPAP at night. ABG results reveal an elevated PaCO2 level. | **Increase IPAP (ventilation)** EPAP (oxygenation) |
| A 80 kg (176 lb) patient with pulmonary fibrosis is being mech vent with Mode: SIMV VT: 700 mL Mandatory rate: 15 Total rate: 15 FIO2: 0.45 PEEP: +10 I:E Ratio: 1:2 PIP: 50 cmH2O pH: 7.34 PaCO2: 42 torr PaO2: 55 torr HCO3-: 22 mEq/L SaO2: 88% | **Increase Fio2 to 60%, Just because its only at Fio2 45%** Increasing PEEP to 20 is a huge jump so that's not good and Shunting isn't present till FIO2 is at 60% Changing to PC mode is only acceptable if they are ARDS |
| Drug Overdose Patient, The respiratory therapist observes wide fluctuations on the pressure manometer during inspiration. The most appropriate action would be to | Increase the flowrate, Most common answer in most situations in troubleshooting |
