NSER 7410 MODULE 3 ACTUAL EXAM WITH COMPLETE SOLUTIONS
Most common causes of death in first 48 hours after burn injury
- Respiratory complications, often related to smoke inhalation
- After 48 hours, sepsis becomes the most common cause of death
Whenever major thermal injuries occur to a BSA > _________ , fluid shifts will be significant
enough to cause some degree of hypovolemia
15-20%
The selection of a particular mode of ventilation determines what?
The extent to which patients participate in their own ventilatory pattern
Assist control ventilation (VOLUME CONTROL)
The most commonly used mode in ED; used when full ventilation is required; apneic
patients or sedated and/or paralyzed patients
Delivers pre-set Vt whether initiated by pt or not
Ideal for resp muscle rest
Pressure Control Ventilation (PCV)
, Used when full ventilation is required for patients with decreased lung compliance
(patients with PCP or ARDS)
Pressure support ventilation
Weaning mode where patients must be able to breathe spontaneously
The inspiratory and expiratory pressures are selected, and there are no mandatory machine
breaths.
Should only be used for patients with a stable respiratory drive (not sedated heavily) and
stable lung compliance.
Synchronized Intermittent Mandatory Ventilation (SIMV)
Is a combination of AC or PCV and PSV
Pt is responsible for Vt when initiating a breath (in contrast to volume control where vent
will deliver full Vt during pt-initiated breath)
Pt may be so weak early on in ventilation, may not be beneficial
BiPAP
Is a non-invasive form of ventilation and is used for alert, compromised patients with COPD
and/or CHF
PEEP recruits alveoli and helps to prevent alveoli from closing >> better gas exchange
