What are the late signs of breathing compromise? - CORRECT ANSWERS - Tracheal deviation
- JVD
What are signs of ineffective breathing? - CORRECT ANSWERS - AMS
- Cyanosis, especially around the mouth
- Asymmetric expansion of chest wall
- Paradoxical movement of the chest wall during inspiration and expiration
- Use of accessory muscles or abdominal muscles or both or diaphragmatic breathing
- Sucking chest wounds
- Absent or diminished breath sounds
- Administer O2 via NRB or assist ventilations with a bag-mask device, as indicated
- Anticipate definitive airway management to support ventilation.
Upon initial assessment, what type of oxygen should be used for a pt breathing effectively? - CORRECT
ANSWERS A tight-fitting nonrebreather mask at 12-15 lpm.
What intervention should be done if a pt presents with effective circulation? - CORRECT ANSWERS
- Insert 2 large caliber IV's
- Administer warmed isotonic crystalloid solution at an appropriate rate
,What are signs of ineffective circulation? - CORRECT ANSWERS - Tachycardia
- AMS
- Uncontrolled external bleeding
- Pale, cool, moist skin
- Distended or abnormally flattened external jugular veins
- Distant heart sounds
What are the interventions for Effective/Ineffective Circulation? - CORRECT ANSWERS - Control
any uncontrolled external bleeding by:
- Applying direct pressure over bleeding site
- Elevating bleeding extremity
- Applying pressure over arterial pressure points
- Using tourniquet (last resort).
- Cannulate 2 large-caliber IV's and initiate infusions of an isotonic crystalloid solution
- Use warmed solution
- Use pressure bags to increase speed of IVF infusion
- Use blood administration tubing for possible administration of blood
- Use rapid infusion device based on protocol
- Use NS 0.9% in same tubing as blood product
- IV = surgical cut-down, central line, or both.
- Blood sample to determine ABO and Rh group
- IO in sternum, legs, arms or pelvis
- Administer blood products
- PASG (without interfering with fluid resuscitation)
What are factors that contribute to ineffective ventilation? - CORRECT ANSWERS - AMS
,- LOC
- Neurologic injury
- Spinal Cord Injury
- Intracranial Injury
- Blunt trauma
- Pain caused by rib fractures
- Penetrating Trauma
- Preexisting hx of respiratory diseases
- Increased age
What medications are used during intubation? - CORRECT ANSWERS LOAD Mnemonic:
L = Lidocaine
O = Opioids
A = Atropine
D = Defasiculating agents
What are the Rapid Sequence Intubation Steps? - CORRECT ANSWERS PREPARATION:
- gather equipment, staffing, etc.
PREOXYGENATION:
- Use 100% O2 (prevent risk of aspiration).
PRETREATMENT:
- Decrease S/E's of intubation
PARALYSIS WITH INDUCTION:
- Pt has LOC, then administer neuromuscular blocking agent
PROTECTION AND POSITIONING:
, - Apply pressure over cricoid cartilage (minimizes likelihood of vomiting and aspiration
PLACEMENT WITH PROOF
- Each attempt NOT to exceed 30 seconds, max of 3 attempts. Ventilate pt 30-60 seconds between
attempts.
- After intubation, inflate the cuff
- Confirm tube placement w/exhaled CO2 detector.
POSTINTUBATION MANAGEMENT:
- Secure ET tube
- Set ventilator settings
- Obtain Chest x-ray
- Continue to medicate
- Recheck VS and pulse oxtimetry
What is a Combitube? - CORRECT ANSWERS A dual-lumen, dual-cuff airway that can be placed
blindly into the esophagus to establish an airway. If inadvertently placed into trachea, it can be used as a
temporary ET tube. There are only two sizes: small adult and larger adult.
What is a Laryngeal Mask Airway? - CORRECT ANSWERS Looks like an ET tube but is equipped
with an inflatable, elliptical, silicone rubber collar at the distal end. It is designed to cover the
supraglottic area.
ILMA, does not require laryngoscopy and visualization of the chords.
What is Needle Cricothyrotomy - CORRECT ANSWERS Percutaneous transtracheal ventilation.
(temporary)
Complications include:
- inadequate ventilation causing hypoxia
