Lecture on Oxygenation by Professor D

Introduction

• The lecture focuses on oxygenation in various medical conditions.
• Encourages viewers to comment with topics they want covered.

Myocardial Infarction (MI)

Possible Complications from Left Ventricular Damage

• Pulmonary congestion (Correct Answer) – related to lung issues, starts with an 'L'.
  • Shortness of breath, dyspnea, crackles
• Right-sided heart failure symptoms: jugular neck vein distension, peripheral edema, liver enlargement
  • All related to blood backing up into the body

Dysrhythmias in Myocardial Ischemia

• Ventricular tachycardia (Correct Answer)
  • Worst dysrhythmia; decreased cardiac output & risk of shock
• Sinus bradycardia and sinus dysrhythmia – considered normal
• Atrial fibrillation – not as severe as V-tach

Narcotic Overdose

• Decreased level of consciousness (Correct Answer)
  • Slow heart rate, cognitive function slowing, risk of coma
• Agitation, hyperpnea, restlessness – signs of hyperstimulation

Assessing Central Cyanosis

• Inspect the client's tongue (Correct Answer)
  • Central cyanosis indicators: face or trunk
  • Peripheral cyanosis: palms, soles, nail beds, earlobes

Pneumothorax Symptoms

• Dyspnea (Correct Answer)
  • Collapsed lung causing difficulty breathing
• Definitions: eupnea = normal breathing, fremitus = vibrations, orthopnea = difficulty breathing lying down

COPD and Oxygen via Nasal Cannula

• Assess nares for skin breakdown every 6 hours (Correct Answer)
  • COPD patients get low-flow oxygen to avoid turning off their breathing drive

Chest Percussion for Respiratory Secretions

• Indicated for cystic fibrosis (Correct Answer)
  • Excessive, thick mucus production
• Not indicated for thrombocytopenia, osteoporosis, or spinal fracture

Early Signs of Hypoxia

• Restlessness (Correct Answer)
  • Major indicator is change in mental state or cognition

Diagnostic Tests with Contrast Material

• Cardiac catheterization (Correct Answer)
  • Important to check for iodine or shellfish allergies

Influenza Vaccination Recommendations

• Any age group with chronic disease (Correct Answer)
  • Chronic illness increases risk and severity of flu complications

Nasotracheal Suctioning Techniques

• Apply intermittent suction for about 10 seconds during catheter removal (Correct Answer)
  • Hyper-oxygenate patient before and after suctioning

Supplemental Oxygen and Suctioning

• Replace the oxygen and allow rest between passes (Correct Answer)
  • Avoid continuous suctioning and using high suction pressures

Transporting with Chest Tube

• Place the end of the tube in sterile water if the collection unit breaks (Correct Answer)
  • Creates a seal to prevent pneumothorax

Sinus Dysrhythmia with Normal Pulse

• No clinical signs (Correct Answer)
  • Sinus rhythms are generally considered normal

Right-Sided Heart Failure Symptoms

• Peripheral edema (Correct Answer)
  • Includes jugular vein distension, facial edema

MI Symptoms in Women

• Epigastric pain (Correct Answer)
  • Women's symptoms are often vague and mistaken for other issues

COPD-Related Fatigue and Activity Intolerance

• Extra energy needed to exhale air from damaged lungs (Correct Answer)
  • Loss of elastic recoil in lungs, leading to barrel chest appearance

Increased Oxygen Needs in Pregnancy

• Increased metabolic demands to support the fetus (Correct Answer)
  • Requires more oxygen for both mother and fetus

Pain Management in Flail Chest Injury

• Pain decreases client's motivation to deep breathe (Correct Answer)
  • Important for re-inflating the lung through deep breathing exercises

MIs in Women – Symptoms

• Significant gastric indigestion (Correct Answer)
  • Important to teach women at risk to recognize this as a potential MI symptom
