The patient's current ventilator settings are: SIMV-Volume Vt 480 ml (f) 20 FIO2 1.0 I:time 0.8 PEEP 5 cmH20 The patient's current vital signs are: BP: 176/98 SPO2 87% CO2 45 mmHg HR: 99 What is the most appropriate intervention to perform for the patient? A. Increase PEEP B. Increase Vt C. Increase (f) D. Decrease inspiratory time E. Decrease Vt - ANSWER C. Increase (f) PEEP should be increased to increase oxygenation. An increased PEEP will help "drive" the oxygen molecule through the alveolar-capillary membrane under higher pressures. This will help to increase a high-pressure gradient to displace pulmonary edema so better oxygenation can take place. (same idea as CPAP in a 911 CHF setting) True or False Patient's with ARDS often require a prolonged expiratory time. A. Yes B. No - ANSWER B. No Patients with ARDS often require a prolonged Inspiratory time (I- Time). Patients with ARDS have a hard time breathing out. Focus on a PAWP 18-20 and oxygenation with increasing PEEP >10, lowering Vt: <8 cc/kg increase rate (f) to maintain minute volume (Vt x rate= minute volume) You have arrived on the scene of a 56 y/o M complaining of chest pain and difficulty breathing with copious amounts of frothy sputum coming out. Your cardiac 12-lead interpretation reveals an Anterior STEMI. Which of the following medications would be the drug of choice for induction in the RSI process? A. Etomidate B. Fentanyl C. Ketamine D. Midazolam - ANSWER A. Etomidate Providers should avoid the use of Ketamine in patients who they suspect are in heart failure. The direct effect of ketamine on the heart is negatively inotropic, especially in heart failure. Etomidate or Versed would be a better choice for induction agents. You are called to transport a patient that is being mechanically ventilated. The patient is currently on the following ventilator settings:
