Student Presentations Flashcards
Most common ECG change seen in intra-operative MI
ST elevation or depression
Goal of hemodynamic mgmt during intraoperative MI
- increase myocardial O2 delivery
- decrease myocardial O2 demand
- maintain CO
T/F: Antiplatelet therapy should always be administered after an intraoperative MI is identified
False
Manifestations of intraoperative MI
- hemodynamic changes
- ST elevation or depression/EKG changes
- elevated cardiac biomarkers (not solely indicative)
Patients at high risk for intraoperative MI
- recent MI or unstable angina
- recent PCI
- emergency sx
- high-risk procedure
2 first line drugs when patient is experiencing hypoxia
- albuterol
- epi
5 causes of hypoxemia
- reduced FiO2
- hypoventilation
- V/Q mismatch
- diffusion impairment
- shunt
Benefit of doing a manual recruitment manever
- correct atelectasis
Cause of hypoxemia that does not respond to supplemental oxygen
shunt
Cardinal sign of hypoxemia
decreased pulse oximetery
3 causes of inaccurate SpO2
- hypothermia
- poor circulation
- artifact
Late signs of hypoxemia
- brady/tachycardia
- arrhythmia/ischemia
- HoTN
- cardiac arrest
Maneuver where you increase inspiratory pressure to 40cmH2O x 15 seconds
recruitment maneuver
3 airway problems that can cause hypoxia
- R mainstem
- autoPEEP
- hypoventilation
3 circulation problems that can cause hypoxia
- severe sepsis
- embolism
- heart disease
Normal amount of fluid in pericardial sac
30mL
Findings consistent with untreated cardiac tamponade
- HoTN
- JVD
- muffled heart sounds
