Health assessment Respiratory system

Introduction Respiratory system ◦ Exchange of gases in the body ◦ Intake of oxygen and release of carbon dioxide Central nervous system ◦ Functions ◦ Maintains acid–base balance ◦ Maintains body fluids ◦ Assists with speech

Anatomy and Physiology Review Upper respiratory tract ◦ Nose, mouth, sinuses, pharynx, larynx, proximal trachea Lower respiratory tract ◦ Distal trachea, bronchi, lungs, pleural membranes, muscles of respiration, mediastinum Respiratory cycle

Anatomy of the respiratory system.

Anatomy and Physiology Review Thorax ◦ Closed cavity containing the structures needed for respiration ◦ Mediastinum ◦ Heart ◦ Trachea ◦ Esophagus ◦ Major blood vessels ◦ Pleural cavities continued on next slide

Anatomy and Physiology Review Thorax ◦ Thoracic cage ◦ Bones ◦ Cartilage ◦ Muscles of the thorax

Lower Respiratory Tract Trachea ◦ 16–20 rings of hyaline cartilage Bronchi ◦ Main bronchus enters each lung at the hilus. ◦ Terminal bronchioles less than 0.5 mm in diameter

Lower Respiratory Tract Lungs ◦ Cone-shaped, elastic, spongy, air-filled structures in pleural cavities ◦ Right lung has three lobes, left lung has two.

Lower Respiratory Tract Pleural membranes ◦ Thin, double-layered serous lining ◦ Surface tension created by fluid and negative pressure between membranes keeps lungs expanded. Mediastinum ◦ Middle section of thoracic cavity ◦ Surrounded by right and left pleural cavities

Landmarks Bony structures ◦ Sternum ◦ Angle of Louis ◦ Clavicles ◦ Ribs ◦ Vertebral column

Landmarks Horizontal and vertical lines ◦ Anterior, posterior, and lateral sections Division of the thorax ◦ Anterior ◦ Imaginary vertical lines ◦ Sternal ◦ Midclavicular ◦ Anterior axillary lines

Landmarks Division of the thorax ◦ Posterior ◦ Imaginary vertical lines ◦ Vertebral ◦ Scapular ◦ Posterior axillary continued on next slide

Landmarks Division of the thorax ◦ Lateral ◦ Imaginary vertical lines ◦ Anterior ◦ Posterior ◦ Midaxillary

Special Considerations Age Developmental level Race Ethnicity Work history Living conditions Socioeconomic status Emotional wellness

Lifespan Considerations Infants and children ◦ Change from intrauterine to extrauterine breathing ◦ Use of abdominal muscles for breathing during infancy and early childhood ◦ Costal breathing expected after age 7 ◦ Smaller airways more prone to blockage continued on next slide

Lifespan Considerations The pregnant female ◦ Muscles and cartilage of the ribs relax. ◦ Inspiratory capacity increases. ◦ Expiratory reserve volume is decreased. ◦ Total lung capacity remains the same. ◦ Oxygen consumption can increase by 20% ◦ Mild respiratory alkalosis

Lifespan Considerations The older adult ◦ Decrease in respiratory efficiency ◦ Changes in respiratory depth ◦ Decrease in cough ability ◦ Increase in respiratory rate ◦ Anxiety and physical exertion can cause significant demands. ◦ Increased effect of infection

Psychosocial Considerations Exacerbation of respiratory problems ◦ Stress ◦ Anxiety ◦ Fatigue ◦ Pain Certain drugs used in the treatment of respiratory disorders may cause hands to tremble.

Cultural and Environmental Considerations Race Ethnicity Presence of allergens Socioeconomic status Incidence of respiratory diseases Geography and environment ◦ Temperature, moisture, altitude, and pollution

Focused Interview Consider patient's ability to participate ◦ If patient is experiencing dyspnea, cyanosis, difficulty with speech, or anxiety, attention must focus on relief of symptoms and restoration of oxygenation.

Focused Interview Focused interview questions ◦ General ◦ Illness or infection ◦ Symptoms, pain, behaviors ◦ Age ◦ Infants and children ◦ The pregnant female ◦ The older adult ◦ Environment

Assessment Techniques Inspection Palpation Percussion Auscultation

Assessment Techniques Observation of skin color Inspection of the anterior and posterior thorax ◦ Symmetry ◦ Configuration ◦ Respiratory rate

Assessment Techniques Palpation of the posterior thorax ◦ Ribs ◦ Intercostal spaces ◦ Respiratory expansion ◦ Tactile fremitus
