Study Notes
Determining Target Heart Rate
- Initial target heart rate for most patients is determined by a healthcare professional.
- Some patients may begin exercise reconditioning without a prescribed target heart rate, possibly due to individual variability or medical conditions.
Karvonen's Formula
- Karvonen's formula is used to calculate target heart rate: (HRmax - HRrest) × %intensity + HRrest.
- This formula takes into account maximum heart rate (HRmax) and resting heart rate (HRrest) to determine an individualized target heart rate.
Maximum Heart Rate Formula
- Maximum heart rate formula is 220 - age.
Target Heart Rate for COPD Patients
- A good target exercise heart rate for patients with COPD is 50-60% of their maximum heart rate.
Cardiopulmonary Stress Testing
- The purpose of cardiopulmonary stress testing is to assess the body's response to exercise and evaluate cardiovascular fitness.
- Obtaining informed consent is crucial before cardiopulmonary stress testing to ensure the patient understands the risks and benefits.
Exercise Testing Methods
- Treadmill testing is advantageous because it allows for a more natural gait and simulates daily activities.
- Analyzing exhaled gases during exercise testing helps assess oxygen consumption and carbon dioxide production.
- The bicycle ergometer is less practical for training muscles compared to a treadmill because it only engages the legs.
Treadmill Adjustments
- A ramp adjustment on a treadmill allows for a gradual increase in exercise intensity.
Stopping Exercise Testing
- When cardiopulmonary stress testing is stopped, the patient is usually monitored for a period to ensure safety and recovery.
Exercise Testing Parameters
- An important parameter measured during exercise testing is oxygen consumption (VO2).
Importance of Patient Evaluation
- Careful evaluation of the patient before, during, and after cardiopulmonary stress testing is crucial to ensure safety and identify any potential health risks.
Exhaled Gas Analysis
- A metabolic cart system analyzes each exhaled breath during exercise testing to assess oxygen consumption and carbon dioxide production.

Description
This quiz covers the physical reconditioning component of a program, focusing on the exercise prescription and determining the target heart rate using methods such as Karvonen’s formula. It also discusses considerations for patients with ventilatory impairment.
