Critical Care Flashcards
Most important parameter to monitor in COPD exacerbation
mental status
restlessness, decreased LOC, difficult arousal, confusion, etc. need to be reported to HCP b/c indication of CO2 retention and worsening hypercapnia
Interventions for pt who has just been extubated
- high fowlers
- warm, humidified O2
- oral care
- deep breathing, coughing, incentive spirometry
- NPO until MBS
When to suction
based on clinical findings such as adventitious breath sounds, elevated peak airway pressure, coughing or signs of resp distress
High-pressure mechanical ventilator alarm causes
- kinked ventilator tubing
- condensation in circuit tubing
- kinked tube
- obstruction (secretions) in tube
- biting tube
- increased airway resistance (bronchospasm, excessive secretions)
- decreased lung compliance (pneumo, atelectasis, pulmonary edema, acute resp distress)
ventilator desynchrony (anxiety, pain, coughing)
Low-pressure mechanical ventilator alarm causes
- tubing disconnect or leak
- tube cuff leak
- loss of airway (total or partial extubation or decannulation)
Complication associated with PEEP
barotrauma
high levels of PEEP (usually kept at 5cm H2O) can cause overdistension and rupture of alveoli -> barotrauma -> pneumo or subcutaneous emphysema
Therapeutic hypothermia
- initiated in clients who are comatose or do not follow commands after resuscitation
- neurologic injury most common cause of mortality in clients who have had cardiac arrest, particularly v fib or pulseless v tach
- therapeutic hypothermia shown to decrease mortality rates and improve neuro outcomes
- client cooled to 32-34 degrees for 24hrs, then rewarmed
nsg: cardiac monitor (brady common), core body temp, BP (MAP > 80), HOB 30 degrees
Frostbite treatment
- remove clothing + jewelry
- do not massage, rub, or squeeze
- warm water heated to 37-39
- analgesia
- elevate injuries after reqarming
- loose, nonadherent, sterile dsgs
- monitor for compartment syndeome
Dopamine infusion
- to treat hypotension, enhances CO by increasing myocardia contractility, HR, and BP through vasoconstriction
- adverse effects = tachy, dysrhythmias, myocardial ischemia
Normal central venous pressure
2-8mmHg
Normal MAP
70-105mmHg
Normal SVR
800-1200dynes/sec/cm
S/S neurogenic shock
- decreased HR
- massive vasodilation
- pooling of blood in venous circulation
- hypotension
- warm and dry skin initially
Initial intervention for SVT
ask client to bear down
Intervention before abg draw from pt on mechanical vent
avoid suctioning pt, can result in inaccurate abgs
