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.
