Care of Clients with Problem in Oxygenation and Cardiovascular System Evan Ruel C. Reglos, RN, MMIHS Anatomy & Physiology Oxygenation Respiratory System Upper Respiratory Known as the upper airway (Nose, Paranasal Sinuses, Pharynx, Larynx Trachea) Warms inspired air Filters inspired air. Respiratory System Lower Respiratory Consist of the LUNGS, which contain bronchial and alveolar structures Accomplishes gas Exchange or Di usion We have 2 Lungs divided into lobes, The Right Lung has 3 and the Left lung has 2 R has 3 lobar bronchi & L has 2 R has 10 segmental bronchi & L has 8 ff Respiratory System Lower Respiratory The Bronchi and Bronchioles is lined and covered with CILIA Cilia creates a constant whipping motion that propels mucus and foriegn substances away from the lungs Alveoli is where O2 nd Co2 exchange takes place (about 300 million in the lungs) Function of the Rrespiratory System Oxygen Transport - O2 to the cell (mitochondria) Respiration -cell to blood and vice versa Ventilation- inspiration and expiration of air that requires in ation and de ation of the lungs fl fl Assessment Health History Always initially focus on the patient's presenting problem and associated symptoms. Check for the. Onset, Location, Duration, Charater, aggravating factors, radiation, frequency, and associated Symptoms. ff Common Sx Dyspnea- Subjective feeling of DOB, maybe pulmonary or cardiac in origin. Can also be associated with allergic reactions, anemia, neurologic, trauma and many more(like post exercise) Pneumothorax - air in the pleural cavity Tachypnea Hypoxemia Orthopnea- found usually to px with Heart disease and occassionally to COPD (Dyspnea with expiratory wheezes) Stridor - high pitched sound during inspiration (blocked airway) Common Sx Cough - re ex that protects the lungs but maybe impaired due to weakness or pralysis of respiratory muscles. Is the result of irritation or in ammation of the mucous membranes anywhere in the respiratory tract. Sputum production Chest pain - should be sharp, stabbing, an intermittent Wheezing - high pitched on expiration and inspiration Rhonchi - low pitched and continous Hemoptysis fl fl Physical Assessment Respiratory System Clubbing of ngers - Diamond shape angle is absent Cyanosis - refer with lips, tongue, nail beds, earlobes fi Diagnostic Evaluation Pulmonary Function Test (Spirometer with recorder) ABG Arterial Blood Gas (Tic Tac Toe). pH 7.35-7.45, PaCo2 35-45 (reversed) HCo3 22-26. Pulse oximetry (95%-100%) Culture- results within 48-72hrs Sputum Studies CXR, CT- Scan, MRI etc. CBC, Neutro (nabaktirya), Eosino (ewwii paraites), lympho( viral) Oxygen Administration Oxygen Therapy - is usually initiated at the onset of chest pain in an attempt to increase the amount of oxygen delivered to the myocardium and to decrease chest pain.

Also known as an advance airway. The Heart Blood Flow The Heart Electrical Impulses/ Conduction System of the heart/Inherent Rate SA Node (SinoAtrial) Pacemaker 60-100BPM AV Node (ArterioVentrical) Gatekeeper 40-60BPM Bundle of HIS 40-60BPM Right and Left Bundle brunch 20-40BPM Perkenje Fibers 20-40BPM The Heart Basic ECG/EKG Reading ECG -
