emt basic notes

Key Conditions:
- Hyperventilation: Characterized by rapid breathing leading to decreased carbon dioxide levels, which may cause lightheadedness, chest pain, or tingling sensations. Understanding its psychological origins, such as panic disorders, is crucial for effective management.
- Congestive Heart Failure (CHF): A condition where the heart is unable to pump effectively, leading to fluid buildup in the lungs and other areas. Symptoms may include dyspnea, swelling in the legs, and fatigue. Management often involves diuretics and lifestyle changes.
- Unconscious/Altered Patients: Requires immediate assessment of airway, breathing, and circulation (ABCs). Use appropriate techniques to open the airway and monitor vital signs closely.

Signs and Symptoms: Recognizing signs such as altered mental status, excessive thirst (polydipsia), frequent urination (polyuria), and potential coma is vital. Rapid identification can lead to quicker interventions such as administering glucose for hypoglycemia or insulin for hyperglycemia.

Indications: Primarily used for chest pain suggestive of myocardial infarction, it works by vasodilation to improve blood flow to the heart. Monitoring blood pressure after administration is critical.
Contraindications: Include hypotension (low blood pressure), recent use of erectile dysfunction medications (which can cause severe hypotension), and increased intracranial pressure, necessitating careful patient history evaluation.

Open-ended Questions: Use these to encourage patients to describe their symptoms thoroughly, facilitating a better understanding of their condition and needs.

Signs and Symptoms: Recognize increasing levels of shock, characterized by tachycardia (rapid heart rate), hypotension (low blood pressure), cool/clammy skin, and altered mental status. Early detection and treatment are essential to prevent progression.

Treatment: Administer epinephrine immediately for anaphylaxis; ensure airway management and monitor the patient for effective response and potential biphasic reactions. Awareness of common allergens affecting the patient is crucial.
Signs and Symptoms: Include urticaria (hives), difficulty breathing (due to airway swelling), and swelling of the face or throat. Education on the use of EpiPens is vital for at-risk patients.

Nephritis: Inflammation of the kidneys, often linked to infections or autoimmune disorders.
Hepatomegaly: Enlargement of the liver which may indicate liver disease or metabolic disorders.
Hydrocephalus: Accumulation of cerebrospinal fluid, requiring careful monitoring and potential intervention.
Pneumonitis: Inflammation of lung tissue, often due to infections or irritants.
Dyspnea: Shortness of breath that can indicate respiratory distress or failure.
Crepitus: A crackling sound in joint movement, often associated with inflammation or injury.
Rhonchi: Rattling sounds in breath, indicating obstruction that may require intervention.
Korotkoff Sounds: Sounds heard while measuring blood pressure, important for accurate assessment of circulatory health.
Subcutaneous Emphysema: Air trapped under the skin, often leading to visible swelling and requiring identification of the source, typically due to trauma.

Procedure: Measure from the earlobe to the tip of the nose; insert gently into the nasal passage with appropriate lubrication to minimize discomfort and potential complications.

Flushed: Temporary reddening of the skin, often a reactive process indicating illness or situational stress.
Diaphoretic: Excessively sweating, which may indicate underlying medical conditions such as hypoglycemia or heat exhaustion.
Edematous: Swelling due to fluid accumulation, frequently requiring evaluation of the underlying cause.

Sizing Procedure: Measure the circumference of the upper arm to choose the correct cuff size, ensuring accuracy in blood pressure readings.

Etiology of TIAs: Temporary interruption of blood flow to the brain, often presenting similarly to strokes but with symptoms resolving within 24 hours.
Etiology of CVAs: Permanent blockage or rupture of blood vessels in the brain, necessitating immediate treatment and rehabilitation to manage long-term effects.

Procedures: Vary according to age groups (adult, child, infant) and conditions (conscious, unconscious). CPR may be necessary if the patient becomes unresponsive.

Airway: Smaller in diameter and shorter in length; more susceptible to obstruction due to anatomical differences. Adverse effects of positioning should be considered closely to maintain airflow. Understanding the underlying physiology is critical for effective intervention.

Assessment and Positioning: Ensure airway stabilization, assess for circulation, and determine the need for rapid intervention while taking care to protect the patient's spine. Additionally, consider the environmental context.
