Monitoring Devices Flashcards
(21 cards)
Systemically developed recommendations that assist the practitioner and patient in making decisions about health care.
Guidelines
Provides rules or minimum requirements for clinical practice.
Standards
Represent the opinions, beliefs, and best medical judgements of the House of Delegates
Standards
What are the two standards are basic anesthesia monitoring?
Standard I: qualified anesthesia personnel must be present in the room during the entire procedure
Standard II: during all anesthetics, the patient must be evaluated continuously for the following- oxygenation Ventilation Circulation Temperature
Using a pulse oximetry, what absorbs more infrared light than red light?
Oxygenated hemoglobin
Using a pulse oximetry, what absorbs more red light than infrared light?
Deoxygenated hemoglobin
What is being measured by the pulse oximetry?
Arterial blood oxygenated vs deoxygenated hemoglobin for SpO2 (%O2 saturation of arterial blood)
What are the factors that cause an increased affinity of hemoglobin for oxygen?
Decreased H+ (increased pH) Decreased temperature Deceased PaCO2 Decreased 2,3 DPG Fetal Hb
What factors decrease the affinity of hemoglobin for oxygen?
Increased H+ (decreased pH) Increased PaCO2 Increased temperature Increased 2,3 DPG Adult Hb
Which way does the oxygen-Hb dissociation curve shift if there is an increased oxygen affinity?
Up and to the left
Is an A-line an indirect or direct measure of arterial blood pressure?
Direct
Where is an A-line placed?
In major arteries of the body with areas of collateral blood flow
What is a NIPB?
A monitoring device that is used to measure cardiac fxn by measuring blood pressure. Reported in mmHg
The peak pressure in the arteries when the ventricles are contracting.
Systolic pressure
The minimum pressure in the arteries when the ventricles are filled with blood
Diastolic pressure
The difference between diastolic and systolic pressures.
Pulse pressure
Arterial pressure being abnormally high
Hypertension
Locations where you can place a NIPB cuff.
Upper arms
Lower arms- not recommended for long period of time or certain patients with bone deformities
Thighs
Calves
Using a blood pressure cuff that is too small will lead to…
Falsely high BP
Using a blood pressure cuff that is too large will lead to…
Falsely low BP
What provides information about CO2 production, pulmonary perfusion, alveolar ventilation, respiratory patterns and the elimination of CO2 from anesthesia circuit to and ventilator?
Capnography
