Questions and Answers
When would each of the following cuffs be used to measure blood pressure? Match the type of cuff to its usage:
Child = For children and for adults with small arms. Adult = For adults with average-sized arms. Thigh = For measurement of blood pressure at the thigh or for adults with large arms.
Explain how to determine the proper cuff size for a patient.
The inner inflatable bladder of the cuff should encircle at least 80% (but no more than 100%) of the arm circumference and should be wide enough to cover two-thirds of the distance from the axilla to the antecubital space.
What may occur if blood pressure is taken using a cuff that is too small or too large?
With a cuff that is too small, the reading may be falsely high; with a cuff that is too large, the reading may be falsely low.
How should the blood pressure be measured if the patient's arm circumference is greater than 50cm (20 inches)?

Study Notes
Vital Signs Overview
- Vital signs provide objective data to assess a patient's health.
- Key vital signs include temperature, pulse, respiration, blood pressure, and pulse oximetry readings.
General Guidelines for Measurement
- Familiarize yourself with normal ranges for vital signs.
- Ensure all measurement equipment is functioning properly.
- Minimize factors that may affect the readings.
- Use a systematic approach during measurement.
Body Temperature
- Normal range: 97°F to 99°F (36.1°C to 37.2°C); average: 98.6°F (37°C).
- Fever: Body temperature above 100.4°F (38°C).
- Body temperature varies daily, peaking in the afternoon and lowest in the morning.
- Heat is produced through muscle activity, metabolism, fever, and emotional states.
Temperature Measurement Sites
- Common sites: mouth, axilla, rectum, ear, forehead.
- Rectal temperatures are generally 1°F higher and axillary temperatures 1°F lower than oral measures.
- Axillary method preferred for young children and patients with oral issues.
Thermometers
- Types: Electronic, tympanic, temporal artery, and chemical thermometers.
- Tympanic thermometers minimize cross-contamination.
Pulse Measurement
- Pulse is felt with each heartbeat due to blood being forced into the arteries.
- Normal pulse rate for adults: 60 to 100 beats per minute.
- Pulse rates vary by age group; infants have a higher normal range.
Blood Pressure
- Measured in mm Hg; normal: less than 120/80 mm Hg.
- Understanding phases of Korotkoff sounds is essential for accurate measurement.
- Blood pressure is influenced by age, activity, and diurnal variations.
Respiratory Rate
- Normal adult range: 12 to 20 breaths per minute.
- One complete respiration consists of an inhalation and an exhalation.
- Respiratory effort changes with physical exertion, emotions, and health conditions.
Oxygen Saturation
- Measured with pulse oximetry to assess oxygen delivery to tissues.
- Healthy oxygen saturation: 95% to 99%.
- Low levels (85% - 90%) can indicate respiratory failure.
Key Factors Impacting Measurements
- Factors such as environmental conditions, equipment cleanliness, and patient cooperation can affect accuracy.
- Dark nail polish and motion may lead to inaccurate pulse oximetry readings.
- Patient conditions can lead to poor blood flow affecting readings.
Korotkoff Sounds Phases
- Phase I: First clear tapping sound, correlating with systolic pressure.
- Phase II: Murmuring or swishing quality.
- Phase III: Sounds are crisper.
- Phase IV: Sounds become muffled.
- Phase V: Sounds disappear, correlating with diastolic pressure.
Equipment for Measurement
- Sphygmomanometers come in mercury and aneroid types.
- Cuff size is crucial; the wrong size can lead to inaccurate blood pressure readings.
Patient Monitoring
- Continuous monitoring with pulse oximetry is essential in acute situations, such as asthma attacks or during sedation.
- Various methods are employed based on the patient's condition and age, ensuring accurate and effective monitoring of vital signs.### Automated Blood Pressure Measurement Devices
- Automatically inflates cuff to approximately 30 mm Hg above systolic pressure for accurate readings.
- Eliminates manual inflation and deflation which simplifies the measurement process.
- Does not require localization of the brachial artery, enhancing user convenience.
- Cuff bladder positioning over the brachial artery is not necessary, allowing for flexibility in use.
- Utilizes electronic sensors to measure oscillations in the brachial artery, negating the need for a stethoscope and listening skills.
- Less affected by external environmental noise compared to traditional manual devices, ensuring more reliable readings.
- Digital display screens make blood pressure readings easy to interpret.
- Can perform multiple blood pressure measurements in a session for more comprehensive monitoring.
- Many devices are equipped with internal memory to store and track previous blood pressure measurements.
