Test 1 part I (Clinical Monitoring) Flashcards
What are the AANA standards for monitoring and alarms?
- Monitor, evaluate, & document physiologic condition as appropriate for procedure & anesthetic technique
- Variable pitch & threshold alarms turned on & audible
- Document BP, HR, RR at least every 5 minutes for all anesthetics
- Oxygenation, Ventilation, Cardiovascular, Thermoregulation, Neuromuscular
- Inspection, Auscultation, Palpation
- Precordial Stethoscope (heart & breath sounds, all forms of anesthesia, Peds) or Esophageal Stethoscope (heart & breath sounds, temperature, only during GA)
