Cardiopulmonary Physical Therapy Flashcards

Which postural drainage position is used to drain the right middle lobe of the lung?

Answer: Left side-lying with foot of bed elevated 15°

The right middle lobe drains best with the patient in left side-lying with the foot of the bed elevated 15° to use gravity assistance.

FEV1/FVC ratio below 0.70 is indicative of which type of pulmonary dysfunction?

Answer: Obstructive lung disease

An FEV1/FVC ratio <0.70 confirms airflow obstruction, as seen in COPD and asthma, where expiration is disproportionately impaired.

Which technique involves applying rhythmic compression to the chest wall during exhalation to mobilize secretions?

Answer: Vibration

Chest vibration applies fine oscillatory force during exhalation to loosen and mobilize bronchial secretions toward larger airways.

A patient's resting heart rate is 95 bpm and target training zone is 60–80% of heart rate reserve using the Karvonen formula. If their maximum HR is 170 bpm, what is the lower training HR?

Answer: 132 bpm

HRR = 170 − 95 = 75; lower target = 95 + (0.60 × 75) = 95 + 45 = 140 bpm — wait, let me recalculate: 95 + 45 = 140... actually 95 + 0.60×75 = 95+45=140. The correct answer is 140 bpm (option B).

Diaphragmatic breathing exercises are prescribed primarily to:

Answer: Improve efficiency of ventilation by maximizing diaphragm use

Diaphragmatic breathing reduces the use of accessory muscles, improves ventilatory efficiency, and reduces the work of breathing.

Which sign or symptom requires immediate cessation of exercise during cardiopulmonary rehabilitation?

Answer: Onset of angina, severe dyspnea, or SpO2 drop below 88%

Angina, severe dyspnea, dangerous arrhythmia, or SpO2 below 88% are absolute indications to stop exercise immediately in cardiac/pulmonary rehab.
