Darrow - Shock Flashcards
What happens to SVR, CO, and PCWP in hypovolemic shock?
Increased SVR to shunt blood to core
Decreased CO and PCWP
What happens to SVR, CO, and PCWP in cardiogenic shock?
Decreased CO
Increased PCWP and SVR
What happens to SVR, CO, and PCWP in distributive shock?
Increased CO
Decreased SVR and PCWP
What is the systolic blood pressure marker for shock?
SBP < 90mmHg
What is the mean arterial pressure marker for shock?
MAP <60-65mmHg
What is Beck’s Triad?
Evaluation for cardiac tamponade
JVD
Muffled heart sounds
Hypotension
What is SIRS?
Systemic Inflammatory Response Syndrome
Dysregulated inflammation related to various disorders
Same category as sepsis
What is the initial acid-base imbalance of SIRS?
Respiratory alkalosis due to hyperventillation
What are the criteria for SIRS?
HR >90bpm
VR >20/min
Temp >38.3C
What is the WBC criteria for SIRS?
>12,000 with >10% bands
When is a pt considered to be in sepsis?
When the pt has SIRS with the presence of bacteria
When is a pt considered to be in severe sepsis?
When the pt’s sepsis has begun to affect one or more organs systems.
When is a pt considered to be in septic shock?
When the pt has severe sepsis and is unable to maintain a MAP >60mmHg after fluid resuscitation
What is early goal-directed therapy for septic shock?
Give fluids to maintain CVP at 8-12mmHg
Give pressors as needed to maintain MAP at >65mmHg
Give Norepi first, then vasopressin
Maintain central venous O2
