SOAP-ME Suction Oxygen Airways (OPA, NPA, Ett) Position: adjust bed Monitoring and Medications: EtCO2, RSI drugs Equipment: DL, VL, bougie what are indicators of a difficult mask? beard,no teeth, OSA, high BMI, age > 55 how should you evaluate a patient for intubatioN? *same order you go through to acutally intubate: 1. neck mobility 2. external face: small mandible, surg scarring 3. mouth (<3 finger breaths of opening is worrying) 4. tongue/pharynx 5. jaw: thyromental distance (from anterior prominence of thyroid cartilage to tip of mandible what are the 2 NM blockers to know for intubation? sux, roc drugs: -lido p 28 a what periintubation drug has been shown to blunt response of increasing ICP in someone whith a head injury? lidocaine (1-1.5 mg/kg) what is goal temp ranges for targeted temperature management? what are the 2 potential big SEs? 32 to 36 C for at least 24 hours in comatose (GCS<8) patients following ROSC SEs: coagulopathy, increased risk of infxn what percentage of normal CO does chest compressions produce? 1/3 what is the goal CO2 following arrest? 38-42 (normocapnea) what are teh 3 broad types of respiratory failure? PNA is most often associated with which one? drug OD? CHF? COPD? dead space ventillation? hypoxemic (PaO2 <60), hypercapneic (PaCO2 >50), mixed hypoxemic (although can be mixed) hypercapneic hypoxemic mixed hypercapneic define shunt physiology? waht is at the other end of the VQ spectrum? no V, still adequate Q dead space what ratio is most useful in tracking hypoxia over time? P:F ratio, PaO2 and FiO2 normal is 300-500 define minute ventilation (VA) VA = RR* (VT - VD) VD = dead space define paradoxical breathing? why does it occur diaphragm is flaccid b/c of fatigue and moves upward during inspiration what FiO2 is given with 2 L NC? 8 L facemask? 28%, 60% what are BiPAP settings to start a patient on (EPAP, IPAP, Vt, backup rate), at what IPAP do you worry about gastric distention? 5, 10, 6-8 mL/kg, 6 IPAP > 20 what are the 4 indications for invasive ventillation? failure to oxygenate, failure to ventilate, failure to protect, projected clinical course what are teh ABCD of teh vent cycle? A: triggering (initiation of inspiration) B: end of inspiratory flow C: cycling (start of expiratory flow) what is assist-control ventilation? VT is guaranteed at present flow rate with a minimum RR however pt can initiate breaths and trigger teh vent, so Pt can breath at higher RR if he wants can be either volume cycled or time cycled (pressure assist), volume is much more common what is PSV? SPV provides a preset level of inspiratory pressure with each vent detected pt effort best for spontaneously breathign pt to offer increased comfort
