Read the first 6 Surgical Equipment Technology flashcards as text

  1. What is the function of an anesthesia workstation's gas delivery system and how does it ensure patient safety?

    Answer: It precisely mixes and delivers gases with safety systems including oxygen ratio monitoring and agent identification

    The gas delivery system precisely controls the mixture of gases and anesthetic agents with multiple safety mechanisms.

  2. How does a harmonic (ultrasonic) surgical device differ from traditional electrosurgery?

    Answer: It uses mechanical vibration at 55,500 Hz to cut and coagulate with lower temperature and less thermal damage

    Harmonic scalpels use ultrasonic vibration creating tissue effects at 50-100 degrees C versus 150-400 degrees C for electrosurgery.

  3. What is an autoclave (steam sterilizer) and what parameters must be monitored?

    Answer: A pressure vessel using saturated steam under pressure at specific temperature, pressure, and time, monitored by physical, chemical, and biological indicators

    An autoclave uses saturated steam under pressure (132 degrees C at 30 psi for 4 minutes or 121 degrees C at 15 psi for 30 minutes).

  4. What is the purpose of a sequential compression device (SCD) and what does a biomedical technician verify?

    Answer: Applies intermittent pneumatic compression to legs to prevent deep vein thrombosis

    SCDs apply sequential pneumatic pressure to leg sleeves to promote venous blood return and prevent DVT.

  5. What is patient-controlled analgesia (PCA) and what safety features must a PCA pump include?

    Answer: A programmable pump allowing patients to self-administer analgesic doses with built-in safety limits

    PCA pumps allow self-administration of analgesic with programmable dose limits, lockout intervals, and maximum doses to prevent overdose.

  6. What is the purpose of a nerve stimulator used during surgery and what parameters must be calibrated?

    Answer: To locate peripheral nerves by delivering controlled electrical stimuli and observing motor response

    Nerve stimulators deliver controlled current pulses to locate nerves for regional anesthesia or surgical preservation.
