Study Notes

Electrocardiogram (ECG) Overview

Provides insights into heart rate, rhythm, and detects heart enlargement or previous heart attacks.
Recommended for symptoms such as chest pain, dizziness, heart palpitations, rapid pulse, shortness of breath, and fatigue.
Continuous ECG monitoring may be needed if symptoms are intermittent.

ECG Types

Holter monitor: Continuous monitoring for 24-48 hours.
Event monitor: Records heart activity when symptoms occur.

12-Lead ECG Precordial Lead Placement

V1: 4th ICS, RIGHT margin of sternum
V2: 4th ICS, LEFT margin of sternum
V3: Midway between V2 and V4
V4: 5th ICS, mid-clavicular line
V5: 5th ICS, anterior axillary line
V6: 5th ICS, mid-axillary line

ECG Procedure Risks

ECG is a safe procedure with no risk of electrical shock; electrodes only record heart activity.
Minor discomfort may occur during electrode removal; some may develop a slight rash.

Respiratory System Anatomy

Includes components: nasal cavity, pharynx, larynx, trachea, and bronchi.
Right and left main primary bronchus lead to the corresponding lungs.

Nebulization

Utilizes a nebulizer for medication administration.
Purpose is to deliver medication directly into the lungs for respiratory conditions.

Chest Physiotherapy (CPT)

Techniques include postural drainage, chest percussion, and vibration.
Aims to remove bronchial secretions, improve ventilation, and enhance respiratory muscle efficiency.

Postural Drainage

Involves positioning the patient to utilize gravity to aid secretion removal.
Secretions are drained into the trachea for removal by coughing or suctioning.

Lung Capacities and Volumes

Total lung capacity for an adult male averages about 6 liters.
Tidal volume represents the amount of air inhaled or exhaled in a single breath.
Adult respiratory rate ranges from 12-20 breaths per minute.

Incentive Spirometer Usage

Breathe through the mouth; maintain an upright position.
Use after exhaling fully to inhale slowly and deeply, aiming for a high piston rise.
Step-by-step guidance on setup and usage is crucial for effectiveness.

Hemodialysis Overview

Treatment for patients with chronic renal disease or acute renal failure.
Blood is drawn, purified through a dialyzer, and returned to the body.
Access points commonly include arteriovenous (AV) fistulas.

Hemodialysis Equipment and Considerations

Comprises a hemodialysis machine and dialyzer.
Strict sterile techniques are necessary to prevent infections and complications.
Continuous monitoring of vital signs (V/S) required, assessing weight and mental status post-treatment.

Complications of Hemodialysis

Potential risks include dialysis disequilibrium syndrome, hypotension, and cardiac arrhythmias.
Serious complications can include air embolism, hemolysis, and exsanguination.

Patient Education for Hemodialysis

Patients should learn care for vascular access sites and understand the dialysis process at home.
Documentation of treatment details, complications, and patient response is essential.

Peak Flow Meter

A device to measure peak expiratory flow, used in respiratory assessments.
Helps monitor asthma and other lung diseases by measuring airflow during exhalation.
