Study Notes

Respiratory Function & Hypoxia

Cyanosis is a bluish discoloration of tissues due to reduced oxygen saturation in the blood.
Assess nail beds, conjunctiva, and mucous membranes for cyanosis in dark-skinned individuals.
Cyanosis is a late sign of hypoxia and can lead to permanent brain damage if untreated.
Skin color is not a reliable indicator of oxygenation status.
Peripheral cyanosis occurs due to vasoconstriction and may be normal.
Central cyanosis is never normal.

Abnormal Lung Sounds

Rales are intermittent sounds heard during inspiration due to air moving through airways containing fluid.
Wheezes are continuous sounds heard during expiration or inspiration as air passes through constricted airways.
Sibilant wheezes are high-pitched whistling sounds.
Sonorous wheezes are low-pitched, rumbling sounds.

Respiratory Function in the Older Adult

Bony landmarks are more prominent due to loss of subcutaneous fat in older adults.
Kyphosis is common, giving the appearance of leaning forward.
Barrel chest deformity can occur, increasing the anteroposterior diameter of the chest.
Tissues and airways become more rigid in older adults, making breathing less efficient.
Risk of respiratory diseases, particularly pneumonia, increases with age.

Promoting Proper Breathing

Deep breathing helps to improve lung function.
Incentive spirometry encourages deep breathing and measures air volume.
Pursed-lip breathing helps to slow expiration and improve air flow.
Diaphragmatic breathing utilizes the diaphragm to increase lung capacity.

Nursing Interventions for Adequate Respiratory Functioning

Teach about pollution-free environments to prevent exposure to irritants.
Promote optimal function by encouraging deep breathing and regular exercise.
Maintain comfort and manage pain to reduce respiratory effort.
Monitor vital signs regularly to assess respiratory status.
Promote effective coughing to clear airways.
Suction airway to remove secretions as needed.
Administer oxygen therapy as prescribed to maintain adequate blood oxygen levels.

Deep Breathing & Coughing

Diaphragmatic breathing focuses on deep, controlled inhalations using the diaphragm.
Pursed-lip breathing involves slow exhalation through pursed lips to prevent airway collapse.
Controlled/huff cough is a technique that helps to clear airways without strain.

Incentive Spirometry

Visual reinforcement for deep breathing, encouraging patients to inhale deeply.
Improves ventilation by promoting deep breathing.
Prevents hypoventilation after surgery or illness.
Loosens respiratory secretions, facilitating their expulsion.
Facilitates gas exchange by keeping alveoli open.
Expands collapsed alveoli, improving lung function.

Promoting Comfort

Frequent position changes every 2 hours help to improve lung expansion.
Adequate fluid intake helps to thin secretions and facilitate their removal.
Humidified air can reduce irritation and ease breathing.
Chest physiotherapy can help to loosen secretions and improve airway drainage.

Oxygen Therapy

Oxygen is a medication, requiring a healthcare provider's order for administration.
Reverses hypoxemia by providing supplemental oxygen.
Onset of action is immediate, providing rapid relief.
Duration of action is short, requiring continuous administration.
Contraindications include COPD patients who may not tolerate high oxygen concentrations.
Adverse reactions can include decreased level of consciousness and respiratory depression in patients with chronic CO2 retention.

Oxygen Delivery Systems

Nasal cannula is a low-flow system with a flexible prongs inserted into the nostrils.
Nasopharyngeal catheter is a soft tube inserted into the nose and pharynx to deliver oxygen.
Transtracheal catheter is a tube inserted through the neck into the trachea for long-term oxygen delivery.
Simple mask is a low-flow system that covers the nose and mouth delivering oxygen.
Partial rebreather mask is a low-flow system that has a reservoir bag to allow for rebreathing of some exhaled air, enriching the oxygen concentration.
Nonrebreather mask is a high-flow system that delivers the highest oxygen concentration, preventing rebreathing of exhaled air.
Venturi mask is a high-flow system that delivers precise oxygen concentrations at variable flow rates, using color-coded jets.

Oxygen Safety

Oxygen supports combustion, requiring precautions to prevent fire hazards.
"Oxygen in Use" and "No Smoking" signs are essential for safety.
Educate clients on home safety measures for oxygen use.

Oxygen Delivery Systems: Low vs High Flow

Low flow systems do not provide enough oxygen to meet the entire inspiratory demand.
High flow systems supply sufficient oxygen for the entire inspiratory demand.

Low Flow Systems

Nasal cannula: delivers low-flow oxygen via prongs inserted into the nostrils.
Simple face mask: covers the nose and mouth, delivering low-flow oxygen.
Partial rebreather mask: allows for rebreathing of some exhaled air to enrich the oxygen concentration.

High Flow Systems

Venturi mask: provides a precise oxygen concentration with variable flow rates, using color-coded jets.
Aerosol mask: delivers humidified oxygen through a mask.
Non-rebreather mask: delivers the highest oxygen concentration by preventing exhalation rebreathing.
Tracheostomy collar and T-piece: delivers oxygen directly into the trachea.
Bag-valve mask: provides manual ventilation with oxygen supplementation.

Nasal Cannula Oxygen Flow Rates

1L/min: provides 21-24% FiO2.
2L/min: provides 25-28% FiO2.
3L/min: provides 28-32% FiO2.
4L/min: provides 32-36% FiO2.
5L/min: provides 36-40% FiO2.
6L/min: provides 40-44% FiO2.

Precautions for Oxygen Administration

Avoid open flames in the patient's room to prevent fire hazards.
Place "No Smoking" signs in conspicuous locations to alert others.
Check electrical equipment for proper working order to prevent fire hazards.
Avoid wearing synthetic fabrics as they can build up static electricity.
Avoid using oils in the area as they can ignite spontaneously in the presence of oxygen.

Noninvasive Positive-Pressure Ventilation (NPPV)

Bi-PAP (Bilevel positive airway pressure) uses two different pressure settings to improve ventilation.
Inspiratory positive airway pressure (IPAP) increases pressure during inhalation, keeping alveoli open.
Expiratory positive airway pressure (EPAP) maintains a lower pressure during exhalation to assist with airflow.
BiPAP machine delivers set IPAP and EPAP pressures with each breath.
Benefits of BiPAP include improved tidal volume, better gas exchange, and reduced airway resistance.

Continuous Nasal Positive Airway Pressure (CPAP)

Delivers a constant positive airway pressure with each breath (both inspiration and expiration).
Keeps alveoli open and improves gas exchange.
Benefits of CPAP include improving ventilation in patients with sleep apnea, atelectasis, and pulmonary edema.

Administering Inhaled Medications

Bronchodilators open narrowed airways by relaxing muscle spasms.
Nebulizers disperse medication into a fine mist for inhalation, allowing for deep lung access.
Metered-dose inhalers (MDIs) deliver a precise dose of medication with each actuation.
Dry powder inhalers (DPIs) deliver medication through a dry powder that is activated by the patient's breath.

Obstructive Lung Disease

Characterized by chronic airflow limitation that is not fully reversible.
Asthma is a condition characterized by airway inflammation and bronchospasm.
COPD (Chronic Obstructive Pulmonary Disease) is a progressive lung disease that includes:
- Emphysema: destruction of alveolar walls, leading to air trapping and decreased gas exchange.
- Chronic bronchitis: excessive mucus production and inflammation of the bronchi.

Asthma

Airway obstruction occurs after initial insult from an allergen that binds to IgE.
Inflammation leads to:
- Bronchial constriction
- Airway edema
- Mucus hypersecretion
- Air trapping
- Hyperinflation
- Epithelial desquamation
- Fibrosis

Asthma Triggers

Viral respiratory infections can trigger bronchospasm.
Allergens such as dust mites, pollen, and pet dander can trigger asthma attacks.
Exercise can trigger exercise-induced bronchospasm.
Cold air can trigger bronchospasm.
Emotional stress can trigger asthma attacks.
Environmental exposure to smoke, pollutants, or fumes can trigger asthma attacks.

Chronic Obstructive Pulmonary Disease (COPD)

Progressive airflow obstruction that is not fully reversible.
Fourth leading cause of death in the U.S.
Includes emphysema and chronic bronchitis.
