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.
