due to unavailability, the patient is unable to go to another location - ✔️✔️extended
care
what is PACU "fast track" - ✔️✔️when you bypass phase I care and move directly from
OR/procedure suite to phase II
AANA standards for Post-anesthesia transfer of care - ✔️✔️1. evaluate the patients
status and determine when it is appropriate to transfer the responsiblity of care
2. communicate the patients condition and essential information for continuity of care
what is the immediate priority of the CRNA and the PACU RN upon admission to the
PACU? - ✔️✔️evaluation of respiratory and circulatory adequacy
what must be included in the anesthesia verbal handoff to the PACU RN - ✔️✔️1. pt
demographic and hx
2. surgical and anesthetic course
3. PACU tx plan/interventions/and endpoints
4. opportunity for RN to ask questions and for CRNA to respond.
what is the purpose of the anesthesia report to the PACU RN - ✔️✔️to ensure pt safety
and continuity of care.
when does postoperative planning begin? - ✔️✔️when patient scheduled for surgery
what is the goal in postoperative planning? - ✔️✔️provide best care/outcomes while
not utilizing unnecessary resources
,what are the three levels of PACU care? - ✔️✔️Phase I, II (outpatient), and Extended
care
the PACU assess and manages: - ✔️✔️1. respiratory and HD status
2. analgesics and antiemetics
3. preparedness for rapid/optimal recovery
4. common post anesthesia complications (which can be prevented and detected with
specialized care)
components of the initial PACU assessment - ✔️✔️1. determine pts physiologic status
at time of admission
2. est pts baseline
3. allow periodic reexamination
4. assess status of surgical site, its effect on preexisting conditions and recovery
5. assess the recovery from anesthesia/residual effects
6. prevent/manage complications
7. provide a safe environment for recovery
8. allow data and trend analysis for discharge or transfer critieria
________________ is the most common cause of upper airway obstructions -

4. subparalytic dose of succ (0.15-.5 mg/kg IV or 4mg/kg IM)
5. may require reintubation
6. consider sedation
PACU management for pt with OSA - ✔️✔️1. planning begins in preop
2. use of regional with minimal sedation (if approp)
3. should have CPAP to use postop
concerns in PACU for pt with OSA - ✔️✔️1. anaglesia
2. positioning
3. oxygenation
4. monitoring
hypoxemia is defined as a paO2 of < _____________ - ✔️✔️60 mmHg
nonspecific signs to hypoxemia - ✔️✔️1. agitation to somnelance
2. HTN - HoTN
3. Tachycardia - Bradycardia
hypoxemia, if left untreated, results in _________________________ - ✔️✔️organ
ischemia
most common causes of hypoxemia in the PACU - ✔️✔️1. atelectasis
2. pulmonary edema
3. PE
4. aspiration & bronchospasm
5. hypoventilation
what is the MOST common cause of postoperative hypoxemia - ✔️✔️atelectasis
, atelectasis post-operatively can lead to an increase in a ______to_______ shunt -
✔️✔️right to left
atelectasis causes in postop - ✔️✔️1. secretions
2. decreased lung volumes
3. hypotension
4. low CO
how do you manage hypoxemia in the PACU? - ✔️✔️1. supplemental humidified O2
2. turn, cough, deep breath
3. postural drainage position
4. mobility
5. incentive spirometry
6. intermittent PPV
_________________ is fluid accumulation within the alveoli - ✔️✔️pulmonary edema
pulmonary edema can occur 2/2 ? - ✔️✔️1. increase hydrostatic pressure 2/2 fluid
overload and cardiac dysfunction
2. increase in capillary permeability 2/2 sepsis, aspiration, transfustion rxn, trauma, DIC
3. decrease in interstitial pressure 2/2 laryngospasm and prolonged airway obstruction
what is it called when you have acute pulmonary edema that occurs shortly after relief
of severe upper airway obstruction? - ✔️✔️postobstruction (aka negative pressure)
pulmonary edema
what are some causes of noncardiogenic pulmonary edema - ✔️✔️1. incomplete
reversal of NMB
2. naloxone bolus
3. significant period of hypoxia
what is a common cause of post-obstruction (negative pressure) pulmonary edema?
(esp in young males) - ✔️✔️biting on the ETT
