Q

Aerobic Exercise Prescription - Intensity

A

Percent of max HR:

- Lower target heart rate = HRmax x 55%
- Upper target heart rate = HR max x 90%

HR reserve or Karvonen formula:

- Lower target heart rate = [(HRmax - HRrest) x 40%] + HRrest
- Upper target heart rate = [(HRmax - HRrest) x 85%] + HRrest

Q

Airway Clearance Techniques - Active cycle of breathing

A

May be used for secretion clearance with asthma

3 Phases:

1) Breathing control - gentle, relaxed breathing at resting TV and RR
2) Thoracic expansion exercises - 3 to 4 deep, slow, relaxed inhalations to inspiratory reserve with passive exhalation. Chest percussion, vibration, or shaking may be combined with exhalation.
3) Forced expiratory technique - One or two huffs at mid to low lung volumes with the glottis open into the expiratory reserve volume. Brisk adduction of upper arms may be added to self-compress thorax.

Precautions/Contraindications:

  • Splinting post-op incisions to achieve adequate expiratory force
  • Bronchospasm or hyperactive airways

Q

Airway Clearance Techniques - Autogenic drainage (AD)

A

Mobilizes secretions by varying expiratory airflow without postural drainage or coughing. Improves airflow in small airways to facilitate movement of mucus.

Pt sitting upright with back support.
Controlled breathing at 3 lung volumes:
-Unsticking phase: slow breath in through nose at low-lung volumes by 2-3 second breath hold then exhale into ERV.
-Collecting phase: breathe at tidal volume, interspersed by 2-3 second breath holds
-Evacuating phase: deeper inspirations from low to mid IRV, breath holding then huff

Treatment 30-45 min

Precautions/contraindications:
Requires motivation and concentration to learn.

Q

Airway Clearance Techniques - Directed cough

A

Tries to compensate for pt’s physical limitations to elicit maximum forced exhalation.

Inhale maximally, close glottis and hold breath for 2-3 seconds
Contract expiratory mm to increase intra-thoracic pressure
Cough sharply 2-3 times through a slightly open mouth
Post-surgical pts may need to splint the chest or abdomen by applying pressure over incision with pillow

Q

Diaphragmatic breathing

A

Minimizes action of accessory muscles and motion of the upper rib cage during inspiration.

Precautions/Contraindications:

  • Moderate to severe COPD and marked hyperinflation without diaphragmatic movement
  • Pt with paradoxical breathing

Procedure:

  • Semi-Fowler’s is a good starting position
  • Sniffing to facilitate contraction of diaphragm
  • One hand on chest, one just below rib cage
23
Q

Inspiratory muscle training (IMT)

A

Attempts to strengthen diaphragm and intercostal muscles if weak or if ventilation is limiting exercise.

Devices can provide 2 training modes: flow resistive breathing and threshold breathing. Flow resistive breathing requires pt to inspire through a mouthpiece with adjustable diameter. Decreased diameter increases resistance to breathing. Threshold breathing requires buildup of negative pressure before flow occurs through a valve that opens at a critical pressure. It provides consistent pressure for IMT regardless of rate of breathing.

Threshold Inspiratory Muscle Trainer:
Measure maximum inspiratory pressure (MIP). Begin training with setting at 30-40% of MIP. With resting TV and RR, breath at this resistance for 5-15 minutes, 2-3x/day. Increase resistance in small increments until training load reaches 40-60% of MIP over a 4-6 week period.

PFLEX Inspiratory Muscle Trainer
Begin training at 30-40% of MIP for 10-15 minutes daily, gradually increasing to 20-30 minutes, 3-5 days/week. Once pt had easily tolerate 30 min, increase resistance to next setting.

24
Q

Paced breathing and exhale with effort

A

To prevent pt from holding breathing during activity. Inhale during resting or less active part of exercise and exhale during movement or more active part of activity.

25
Q

Pursed-lip breathing (PLB)

A

Helps reduce RR, dyspnea, and maintain small positive pressure in bronchioles to prevent airway collapse.
Semi-fowler’s is good position to start in.

26
Q

Segmental breathing

A

Intended to improve regional ventilation and prevent and treat pulmonary complications after surgery. To prevent or decrease asymmetrical chest wall motion.

PT applies firm pressure at end of exhalation to chest wall overlying area to be expanded. Pt inhales deeply and slowly expands rip cage under PT’s hands. PT reduces pressure during inhalation.

27
Q

Sustained maximal inhalation with incentive spirometer

A

Maintain max inspiration for 3 or more seconds. Often used in airway clearance.

28
Q

Forward leaning with arm support

A

Can provide relief of dyspnea to patients with lung disease. Allows pec muscles to assist in elevating rib cage during inspiration.

29
Q

Reverse Trendelenburg position

A

Supine with head above trunk and LEs. Decreases weight of abdominal contents on diaphragm.

30
Q
