Hypercarbic Respiratory failure is considered how much CO2?
> 50mmHg CO2
Causes of Hypercarbic Respiratory failure?
Inadequate alveolar ventilation 2nd to decreased minute ventilation (TV x RR)
or
Increased dead space ventilation (No perfusion)
TXT of Respiratory failure

Pulse alterations
MC type of shock is?
Hypovolemic shock
What is the MC type of shock in PEDs?

Distributive shock is?
Adequate volume but maldistribution of blood flow
Pathophys of Distributive shock is?
V-Dil > Venous pooling > Decreased preload
MC cause of Distributive shock is??
Sepsis > SIRS > Anaphylaxis
S/S of Distributive shock is?
\+- bounding pulses, HOTN, V-Con Warm shock (Nl PE) > Cool extremities/mottling > decreased cap refill
Distributive shock due to sepsis will present w/?

TXT of shock?
Recognize early (when in partial state)
Guided by S/S - CV vs Respiratory vs Renal
Loop diuretics after volume replacement
Leading cause of death in pediatric trauma?
MVC
MC type of trauma in Pediatrics?
Head trauma > limbs
Will a cervical XR catch injuries to the neck w/ PEDs?
