blisters, pain, etc. Superficial thick: SUNBURN only epidermis, least damage (peeling) Partial
thick: dermis and epidermis (sun, scald, grease) super-partial thick: 1/3 dermis damage, blisters,
good blood supply still, increased pain need pain meds before touching pt. deep partial thick: no
blisters-too deep, nerves destroyed
➢ Cardiac changes: Release of catecholamines, vasopressin, and angiotensin II causes intense
vasoconstriction and increased SVR
BP & HR elevated
Initial attempt to conserve fluid
Increased capillary force also promotes burn edema
CO decreased due to release of vasocontrictive agents and increased SVR and CO workload
Cardiac function continues to be depressed even after adequate fluid resuscitation
Myocardial depressant effects of inflammatory mediators
Tumor necrosis factor (inflammatory biochemical) released from burn wound

treatment- prevent VAP ETT removed suction and oral care; low pressure alarm caused by losing
pressure could be cuff leak, disconnection; high pressure alarm mucus plug, kink, biting tube;
agitated patient what does the nurse assess for low O2, pain; dyspneic with normal O2 sat -ARDS
➢ Flail chest – anticipated interventions : pos. pressure, pain mngmt NO CHEST TUBE
➢ Understand refractory hypoxemia – wide spread inflammatory response seen in what disease
process? ARDS
CARDIAC
➢ Understand ECG complex – think about what is going on in the heart if there is no P wave with
every QRS, or if a segment lengthens i.e. what part of the conduction system of the heart
controls the rate-SA node; what wave is not normally seen on ECG- U wave not seen

patient education- Take own pulse; what two meds will patient with afib have long term are
