(central venous pressure line) a venous line which is placed into the subclavian vein with the tip of the catheter in the SVC just superior to the right atrium of the heart. The pressure within the SVC reflects the pressure under which the blood is returned to the right atrium. If increased, this can indicate CHF. If decreased, this indicates hemorrhage or fluid loss.
Distrubances in conduction caused by electrical impulses that do not originate from the SA node.
diagnostic procedure consisting of recording the activity of the heart electronically with a cardiograph (and producing a cardiogram)
regional anesthesia resulting from injection of an anesthetic into the epidural space of the spinal cord
loss of sensation in a small area of the body (as when a local anesthetic is injected for a tooth extraction)
a noninvasive method of measuring oxygen in the blood by using a device that attaches to the fingertip
loss of sensation in a region of the body produced by application of an anesthetic agent to all the nerves supplying that region (as when an epidural anesthetic is administered to the pelvic region during childbirth)
hormone from renial medulla that raises blood pressure, a catecholamine secreted by the adrenal medulla in response to stress (trade name Adrenalin)
an itchy skin eruption characterized by weals with pale interiors and well-defined red margins
Local anesthetics can metabolize to ___ which cause allergies due to metabolism in para-aminobenzoic acid.
Starts as the patient begins to awake from the altered state induced by the anesthesia and usually ends when the patient is ready to leave the OR.
Begins with administration of the anesthetic agent and continues until the patient is ready for the incision.
surgical intervention takes place during this phase; maintenance of homeostatic function of all vital organs critical to successful anesthetic delivery and surgical outcome
Minimum alveolar concentration
the minimum concentration of an inhalation anesthetic in the alveolus that prevents 50% of patients from responding to a painful stimulus.
pumps air or oxygen through a liquid medicine to turn it into a vapor, which is then inhaled by the patient via a face mask or mouthpiece
Opioids provide an analgesic effect by decreasing the perception of pain and increase pain tolerance.
