Is Pressure Normal with Rib Fractures?
Yes, pressure sensation is a normal and expected symptom of rib fractures, resulting from chest wall instability, pain-related splinting, and the mechanical disruption of the thoracic cage.
Understanding the Symptom
The "pressure" sensation you're experiencing stems from several physiologic mechanisms that occur with rib fractures:
- Mechanical instability of the chest wall creates abnormal movement patterns during breathing, which patients often describe as pressure, tightness, or a sensation of chest wall restriction 1
- Pain-induced splinting causes shallow breathing and muscle guarding, leading to a feeling of chest tightness and pressure 2
- Atelectasis and secretion accumulation from inadequate deep breathing creates a sensation of chest heaviness or pressure 1, 2
Clinical Significance of Pressure Symptoms
While pressure is normal, it serves as an important warning sign:
- Splinting from pain leads to shallow breathing, which progresses to atelectasis, then poor secretion clearance, and ultimately pneumonia—the common pathway to respiratory failure in rib fracture patients 2
- Each additional rib fracture increases pneumonia risk by 27% and mortality by 19% in elderly patients 2
- Persistent chest tightness and dyspnea on effort are documented long-term complaints in patients managed non-operatively, even at 12 months follow-up 1
When Pressure Becomes Concerning
You need immediate evaluation if pressure is accompanied by:
- Respiratory distress (respiratory rate >20 breaths/minute) 1, 3
- Hemodynamic instability 3
- Paradoxical chest wall movement (flail chest) 1
- Inability to take deep breaths despite pain control 1
- Poor cough effort 1
Management Algorithm for Pressure Symptoms
Immediate Pain Control (First Priority)
- Multimodal analgesia must be started promptly and proactively on hospital admission to break the pain-splinting-atelectasis cycle 4, 2
- Consider regional anesthetic techniques (thoracic epidurals, erector spinae blocks) for significant chest trauma or high-risk patients 4
Respiratory Support (Second Priority)
- Aggressive pulmonary hygiene and chest physiotherapy to prevent atelectasis 1, 5
- Rapid mobilization to improve respiratory mechanics 5
- Incentive spirometry with goal >50% predicted 1
Monitoring for Complications
- Calculate a rib fracture score to identify high-risk patients requiring intensive monitoring 4
- Watch for pulmonary complications, which occur in 35% of rib fracture patients 6
Common Pitfalls to Avoid
- Do not dismiss pressure as "just pain"—it indicates inadequate respiratory mechanics that can progress to pneumonia 2, 5
- Do not rely on pain control alone—respiratory support and mobilization are equally critical 5
- Do not discharge without ensuring adequate pain control AND respiratory function, as pulmonary complications remain a significant risk 7
