FROM MY PT SCHOOL NOTES · GENERAL MEDICAL / POST-SURGICAL · CHAPTER 6
Why Does Breathing and Cardiac Status Matter After Surgery?
The same short walk can be trivial for one person and a major physiologic demand for someone after thoracic or abdominal surgery.
Understand postoperative pulmonary changes
The course discusses pulmonary complications after surgery. Anesthesia, pain, impaired cough, reduced ventilation, immobility and underlying lung disease can contribute to atelectasis or other respiratory problems. Thoracic and upper-abdominal incisions may make deep breathing and position changes uncomfortable.
Recognize concerning cardiopulmonary symptoms
A major cardiopulmonary topic in the source lecture is recognizing possible myocardial ischemia or infarction: chest pressure is common but symptoms may also include shortness of breath, diaphoresis, nausea, unusual fatigue or atypical discomfort, particularly in some older adults or people with diabetes. After thoracic or abdominal surgery, new instability, unexpected respiratory deterioration or concerning wound/drain changes require prompt team assessment.
Relevant PT interventions include early but medically appropriate upright activity, walking or short transfers, breathing strategies, supported cough when indicated, activity pacing and monitoring the response to effort. Coordinate treatment timing with pain management, oxygen needs and medical orders.
Match activity to recovery
Stop and communicate unexpected new chest pain, marked breathing difficulty, rapidly changing oxygen needs, concerning hemodynamic changes or altered mental status. A patient’s signs and trajectory matter as much as the exercise planned.
VTE is a major postoperative consideration. New unilateral leg swelling/pain or sudden cardiopulmonary symptoms requires appropriate assessment and medical-team communication. Homan’s sign is not a reliable test to rule out DVT.
Reasoning check: Should new chest discomfort during activity be ignored until a planned walking target is finished?
No. Stop or modify, assess safety and communicate or escalate promptly under facility procedures.
Make the clinical connection
Scenario: A patient after thoracic surgery reports new pressure-like chest discomfort and unexpected breathlessness while walking farther than earlier in the morning.
What is the next reasoning step?
Reasoning: Stop the task, help the patient into a safe position, assess and promptly contact the clinical team or activate the appropriate response pathway. Such symptoms are not simply an expected exercise-training effect.
Common mistake: Pushing for the planned distance because early mobility is generally beneficial. Remember: The response during activity overrides the original session goal.
