Study Notes
Definitions
- Hypoxemia: Characterized by low oxygen levels in the bloodstream, potentially affecting overall oxygen delivery to tissues.
- Hypoxia: Refers to insufficient oxygen availability in tissues throughout the body, impacting cellular function and metabolism.
Early Signs of Hypoxemia
- Symptoms include tachypnea (increased breathing rate) and tachycardia (increased heart rate).
- May manifest as restlessness and changes in skin color, such as pale skin and mucous membranes.
- Often accompanied by elevated blood pressure and indicators of respiratory distress.
Late Signs of Hypoxemia
- Severe symptoms include confusion and stupor, reflecting impaired cognitive function due to inadequate oxygenation.
- Physical indicators include cyanotic skin and mucous membranes, signaling significant oxygen deprivation.
- Other late signs comprise bradypnea (decreased respiratory rate), bradycardia (decreased heart rate), hypotension, and potential cardiac dysrhythmias.
Early Signs of Hypoxia
- Early symptoms may involve heightened restlessness, tachycardia, and tachypnea.
- Patients might experience dyspnea (difficulty breathing) along with increased agitation and anxiety.
- Additional signs can include diaphoresis (excessive sweating), retractions during breathing, and headache.
Late Signs of Hypoxia
- Progression leads to increased restlessness and stupor, indicating severe oxygen deprivation.
- Patients may exhibit marked dyspnea and significantly decreased respirations, which require urgent attention.
- Early indicators evolve into bradycardia and cyanosis, necessitating immediate medical intervention.
