Blood Gasses and Resp Therapy Flashcards
What type of respiratory failure does this patient have?
PO2 < 60mm Hg
Type 1 - Hypoxemic
What type of respiratory failure does this patient have?
PCO2 > 45mm Hg
Type 2 - Hypercapnic
- pump failure
What are the primary causes of Type 1 respiratory failure?
- V/Q mismatch
- shunt (alveolar collapse)
- Impaired diffusion
- Alveolar hypoventilation
- Decreased inspired O2 (PiO2)
What does hypercapnic refer to?
Retention of CO2
How is DVT diagnosed?
- D-dimers test
- Wells Score
- Ultrasound of legs
What is a pneumothorax?
Air in the pleural space causing a collapsed lunge
- open, closed and tension
What is a pulmonary embolism and how is it diagnosed?
Thrombus breaks off from a clot and blocks pulmonary arteries
- D-dimers test
- CT scan of lungs
- Ultrasound of vessels
What are the common causes of a shunt?
Atelectasis, pulmonary edema, pneumonia
What is the goal of oxygen therapy?
Decrease the workload hypoxemia imposes on the cardiopulmonary system?
What are the primary causes of Type 2 respiratory failure?
Ventilatory failure
- Alveolar hypoventilation
- Neuro disease impacting breathing
- increased work of breathing
- respiratory impairment
What is the purpose of pharyngeal airways?
suctioning nasotracheal area
What is HIPPA?
History, inspection, percussion, palpation, auscultation
Why do we get preferential ventilation in the dependent lung?
- Lung compliance is better (PV curve)
- The alveoli in the dependent area are less inflated and more compliant
