Study Notes

Oral Temperature Measurements

Most convenient and acceptable method for alert adults.
Not ideal for infants or orally intubated patients.
Delivery of oxygen via nasal cannula can affect oral temperature readings.

Tympanic Thermometry

Offers rapid, clean, and noninvasive temperature measurement.
High correlation with core temperatures confirmed in studies.
Preferred in pediatric assessments but speed is the main advantage.
Concerns raised regarding accuracy in clinical settings.

Pulse Rate

Normal range for adults: 60 to 100 beats per minute; must be regular in rhythm.
Tachycardia defined as a pulse rate above 100 beats/min.
Monitoring heart rate in lung disease is crucial due to potential hypoxemia.

Assessing Pulse Characteristics

Important to evaluate rate, rhythm, and strength of the pulse.
In low blood pressure scenarios, use femoral artery for pulse measurement.
Pulsus paradoxus indicated by significant pulse pressure decrease during inhalation.

Blood Pressure Insights

Diastolic blood pressure reflects pressure during left ventricular relaxation.
Normal pulse pressure: 35 to 40 mm Hg; detection becomes difficult below 30 mm Hg.
Systemic hypertension risks: heart, kidneys, and blood vessels; pancreas generally not affected.

Hypotension

Common causes include left ventricular failure, peripheral vasodilation, and hypovolemia; right heart failure is not a direct cause.
Orthostatic hypotension refers to blood pressure changes with posture, especially in hypovolemic patients.

Korotkoff Sounds

Arterial blood pressure measurement relies on observing Korotkoff sounds through a stethoscope.
Significant blood pressure drops during inhalation can indicate an abnormality, known as paradoxic pulse.

Clinical Scenarios for Respiratory Therapists

Hypothermic patients require heated, humidified air rather than an HME to aid in temperature recovery post-intubation.
Elevated respiratory parameters may not be appropriate in hypothermic conditions.

Summary of Assessment Techniques

Accurate pulse and temperature assessment is critical in patient care, particularly in compromised patients.
Continuous observation and reassessment are vital for maintaining patient safety and comfort.
