Definition:
Hypoxemia: Low levels of oxygen in the blood.
Oxygen Therapy: Signs and Symptoms of Hypoxia
Symptoms:
Decreased Level of Consciousness (LOC)
Confusion
Drowsiness
Altered Concentration
Dizziness
Increased Pulse
Increased Rate and Depth of Respiration or Irregular Patterns
Increased Blood Pressure evolving to Decreased Blood Pressure
O2 Saturation < 90%
Decreased Lung Sounds with Adventitious Sounds
Dyspnea
Pallor
Cyanosis
Accessory Muscle Use
Cardiac Arrhythmias
Increased Fatigue
Treatment and Administration of Oxygen
Oxygen as a Medication:
Administer according to the 10 Rights of Medication
Selection of Oxygen Devices Based On:
Level of Oxygen Required
Severity of Hypoxia
Disease Process
Additional Factors:
age and developmental level
health status
level of orientation
presence of artificial airway
setting (acute vs. community)
support available
Oxygen Delivery Methods
Nasal Cannula:
Flow Rate: 1-6 L/Min
O2 Concentration: 24%-44%
Humidity: Higher levels should be given with humidity
Advantages:
Safe, simple, easily tolerated, allows eating/drinking
Disadvantages:
Contraindicated with nasal obstruction, drying to mucous membranes, can be dislodged, skin breakdown, and breathing pattern affects FiO2
Simple Mask:
Flow Rate: 5-10 L/Min
Usage: Used for short periods
Contraindications:
Not for CO2 retainers, increased risk of aspiration
WARNING: If < 5 L/min, can cause hypoxia
Partial and Non-Rebreather Mask:
Flow Rate: 10-15 L/Min
O2 Concentration: Delivers 60-80% O2
Benefits: Easily humidifies and does not dry mucous membranes
Venturi Mask:
O2 Concentration: 24-50%
Functionality: Provides a specific amount of O2 based on the adapter
Oxygen Safety
General Guidelines:
Oxygen is a medication and levels should not be adjusted without consulting a healthcare provider
An “OXYGEN IN USE” sign should be posted at the client's residence
Oxygen delivery systems should be at least 3 meters (10 ft) from heat sources
Oxygen is combustible but does not explode
Oxygen cylinders must be secured upright
No smoking allowed in areas where oxygen is in use
Ensure electrical equipment is functioning and properly grounded
Avoid anything that might create a spark, e.g., electric razor
Check oxygen levels of portable tanks before client transport
Nursing Role in Oxygen Delivery
Roles involve:
Assessing the patient’s respiratory status
Administer oxygen as per prescribed protocols
Promoting Airway Clearance
Purpose: To promote bronchial hygiene and clear airway while maximizing gas exchange
Interventions Include:
Client Positioning
Deep Breathing and Coughing
Using an Incentive Spirometer
Pursed Lip Breathing
Client Positioning
Effective Positions:
Semi-Fowler’s
High Fowler’s
Tripoding or Orthopneic position promotes chest expansion
Deep Breathing and Coughing
Benefits:
Facilitates opening of alveoli, mobilizing, and clearing secretions
Indicated for patients with chronic lung diseases, post-surgical conditions, and pneumonia
Incentive Spirometry
Function: Encourages practice of deep breathing
Feedback: Provides visual feedback to encourage long, slow breaths
Impact: Helps decrease risk of pulmonary postoperative complications when used alongside other techniques
Pursed Lip Breathing
Purpose: Helps patients control breath pace
Benefits: Promotes prolonged oxygen exchange and prevents airway collapse
Nursing Diagnoses
Common Diagnoses:
Impaired gas exchange (actual or risk for)
Impaired ventilation
Inability to fulfill roles related to respiratory compromise
Anxiety related to dyspnea
Insomnia related to orthopnea
Activity intolerance
Developing a Patient Care Plan
Overall Goals:
Improve comfort and ease of breathing
Maintain or improve pulmonary ventilation and oxygenation
Improve tissue perfusion
Enhance ability to participate in physical activities
Encourage health-promoting behaviors
Implementing Oxygenation Promotion
Nursing Interventions Include:
Change positions frequently
Encourage ambulation
Provide comfort measures
Administer fluids and humidification
Teach deep breathing and coughing methods
Use of pursed lip breathing and incentive spirometry
Patient and Nurse Safety
Importance of Safety:
Patient safety and nurse safety are interconnected
Nurses have professional and ethical duties to address safety concerns
Unsafe care usually reflects systemic failures rather than individual mistakes
Safety Terminology
Near Miss: An event caught before reaching the patient (also called good catch)
Adverse Event: An incident resulting in patient harm unrelated to their medical condition
Critical Incident: An adverse event leading to significant physical impairment or death
Patient Safety Statistics
Adverse Events:
7.5% of all patients experience adverse events
35% of those events are considered preventable
Safety Systems Approach
Swiss Cheese Model:
Safeguards consist of slices with holes representing weaknesses
Weaknesses aligning can lead to harmful events
Domino Effect:
Visualizes events cascading through system layers leading to patient harm
Iceberg Model:
Identifies visible and underlying contributing factors to patient safety issues
System-Wide Approach:
Learning from events to improve systems, emphasizing teamwork and communication
Nurse Safety and Violence Prevention
Incidents: All incidents of violence should be reported
Awareness: Be aware of surroundings to prevent and minimize risks
Culture of Safety
Reporting Culture: Trust in the reporting process without fear of punishment
Informed & Flexible Culture: Continuous awareness of issues and adapting systems for safety improvements
Risk Management in Safety Culture
Components: Quality improvement, investigation, root cause analysis, psychological safety
Falls Prevention
Statistics:
>1/3 of seniors experience falls
Associated with significant health risks and costs of ~$2 billion annually
Universal Fall Precautions
SAFE Approach:
Safe Environment: Ensure environments are free of hazards
Assist with Mobility: Support patient movement to prevent falls
Fall Risk Reduction: Engage patients and families in safety measures
Restraints in Healthcare
Definition: Restrictions preventing injury or managing behavior that threatens safety
Best Practice: Use restraints as a last resort, following policies and obtaining physician orders
Physical Restraint Guidelines
Procedure:
Attempt alternative methods first, obtain history and physical exam, explain restraints to patients
Document rationale and adhere to all applicable regulations
Alternatives to Restraints
Examples:
Therapeutic management, alarms, mattress adjustments, assistive devices
Bed Rails Considerations
Common Myths:
Belief that bed rails are entirely safe or useful for fall prevention
Risks: Injuries, agitation, isolation, and accidental deaths related to improper use
Best Practices for Bed Rails
When to Use:
Assistance with mobility, requested by capable patient, short-term use with assessment
When to Avoid: Confusion, risk for climbing or falls, reduced strength
Codes in Emergency Situations
Code Blue: Cardiac arrest/medical emergency
Code Red: Fire
Code White: Violent patient
Code Yellow: Missing patient
Code Green: Evacuation
Code Orange: Environmental disaster
Code Brown: Chemical spill
Code Black: Bomb threat
Code Purple: Hostage taking
