Cardiorespiratory Flashcards
What are the 11 reasons to not do early mobilisation
- Blood pressure
- Bleeding
- Broken hearted
- Brain explosion
- Blood thinners
- Bones
- Brady/Tachycardia
- Breathlessness
- Bilious
- Belligerent
- Bugger it
- Oh the pain
Reasons for respiratory acidosis
Alveolar hypoventilation
- Respiratory muscle weakness/fatigue
- Post-op drowsy
- Effects of analgesia depressant drugs
Reasons for metabolic acidosis
- Renal failure
- Diarrhoea
- Uncontrolled diabetes mellitus
Reasons for respiratory alkalosis
Hyperventilation
- Anxiety
- Fear
- Pain
- Fevers from sepsis pulmonary embolism
- Acute asthma mechanical-over-ventilation
Reasons for metabolic alkalosis
- Excessive alkaline ingestion
- Large nasogastric aspiration
- Persistent vomiting
Calculating PaO2
- FiO2 (e.g. RA, 30%) x 5
2. P/F ratio (norm values: 450-500)
Interpreting PaO2 levels (<80mmHg, <60mmHg)
- <80mmHg: hypoxaemic
2. <60mmHg = respiratory failure
FET has 3 components
- Breathing control
- 1 or 2 huffs
- Breathing control
FET is used for
Patients with excessive secretions and are SOB or have increased WOB
FEV1 is
The volume of air that can be forcibly blown out in 1 second after full inspiration - indicative of obstructive diseases
FEV1 normal values
80-120%
FVC is
After a maximal inspiration, this is the volume of air which can be forcibly and maximally exhaled out of the lungs until no more can be expired - indicative of restrictive diseases
FEV1/FVC ratio normal values
75-80% - reduced ratio is indicative of obstructive diseases
FEF 25-75
Flow of air coming out of lungs during middle portion of a forced expiration - detects obstructive small airway disease
Obstructive disorder: 3 components
- FEV1 reduced <80%
- FVC normal but usually reduced to a lesser extent than FEV1
- FEV1/FVC ratio <70%
Restrictive disorder: 3 components
- FEV1 reduced <80%
- FVC reduced <80%
- FEV1/FVC ratio normal >70%
