Study Notes
Hypoxia and Oxygen Saturation
- Hypoxia refers to a deficiency in oxygen reaching tissues, while oxygen saturation measures the percentage of hemoglobin bound with oxygen.
- Normal oxygen saturation levels range from 95% to 100%, while levels below 90% indicate hypoxemia.
Arterial Blood Gases (ABGs)
- ABGs measure the partial pressure of oxygen in arterial blood, critical for assessing oxygenation status.
- Normal partial pressure of oxygen: 80-100 mmHg; lower values indicate hypoxemia.
Sputum Production
- Healthy individuals produce up to 100 mL of tracheobronchial secretions daily.
- Increased sputum production may indicate respiratory conditions, requiring effective clearance methods such as coughing or huffing.
- Baseline assessment should inquire about normal sputum production and how conditions can improve it.
- Use Borg scale for quantifying exertion; target range is 3-4 during training.
Wheezing
- Wheezing is a whistling sound during expiration caused by airway narrowing, often signaling obstruction.
- Causes of obstruction include bronchospasm (e.g., asthma), edema (e.g., heart failure), or foreign bodies.
- Types of wheezes:
- High-pitched wheeze indicates near-total obstruction.
- Fixed monophonic wheeze suggests a single obstructed airway.
- Polyphonic wheezes signify widespread narrowing.
- Localized wheeze may relate to sputum retention.
- Evaluate patient history on pre-existing wheezing, duration, and factors that exacerbate or alleviate the condition.
Hemoptysis
- Hemoptysis is the coughing up of blood, with frank hemoptysis indicating significant bleeding that can be life-threatening.
- Isolated hemoptysis could suggest early-stage bronchogenic carcinoma.
- Chronic lung disease patients, such as those with cystic fibrosis or bronchiectasis, may experience recurrent hemoptysis.
- Baseline considerations include the patient's usual status regarding hemoptysis and the volume coughed up.
- Assess ongoing home oxygen requirements: duration and liter flow needed.
Chest Pain
- Chest pain may stem from various origins, including musculoskeletal, cardiac, pleural, or tracheal issues.
- Differentiate between stable and unstable angina, and consider myocardial infarctions as potential causes.
- To assess chest pain:
- Onset duration and previous episodes are critical.
- Location analysis: localized or referred pain provides diagnostic clues.
