Summary
Spinal cord injury (SCI) survivors, especially those with high cervical injuries, face significant risks of breathing problems during sleep. Early diagnosis and interventions like ventilation can improve outcomes for these patients.
Area of Science:
- Neurology
- Pulmonology
- Sleep Medicine
Background:
- Spinal cord injury (SCI) affects approximately 12,000 individuals annually in the US.
- High cervical SCI (C2-C8) significantly impairs respiratory function, increasing risks of hypoventilation and sleep-disordered breathing.
- Reduced vital capacity and ventilatory reserve are common due to neural pathway interruption.
Purpose of the Study:
- To highlight the risks of hypoventilation and sleep-disordered breathing in SCI patients.
- To outline diagnostic methods for respiratory impairment in SCI.
- To review available treatment options for respiratory support in SCI.
Main Methods:
- Diagnosis involves measuring pCO2 with capnography during wakefulness and sleep.
- Polysomnography is recommended to comprehensively evaluate sleep-disordered breathing.
- Assessment of vital capacity and ventilatory reserve is crucial.
Main Results:
- SCI patients, particularly those with high cervical injuries, are prone to hypoventilation, especially during sleep.
- Aging exacerbates the risk of sleep-disordered breathing in this population.
- Restrictive ventilatory impairment is a common consequence, with preserved diffusing capacity.
Conclusions:
- Early diagnosis of respiratory compromise in SCI is essential.
- Treatment strategies range from diaphragmatic pacing to various forms of positive pressure ventilation.
- Mechanical ventilation, potentially limited to sleep, may be required for some individuals.

01:25Secondary Spinal Cord Injury llI: Pathophysiology
Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
01:21Acute Respiratory Failure-II
Type I Respiratory Failure, or hypoxemic respiratory failure, occurs when the partial pressure of oxygen (PaO2) in arterial blood falls below 60 mmHg while breathing room air without a corresponding increase in arterial carbon dioxide levels (PaCO2). This condition highlights a significant impairment in the lungs' capacity to oxygenate the blood.
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:

01:30Acute Respiratory Failure-III
Hypercapnic respiratory failure, also known as Type 2 or ventilatory respiratory failure, is a severe condition characterized by the body's inability to effectively remove carbon dioxide (CO2) from the bloodstream. It leads to an arterial CO2 pressure (PaCO2) exceeding 45 mmHg and a blood pH above 7.35. This situation indicates that the body's ventilatory demand, or the ventilation needed to maintain normal PaCO2 levels, surpasses its supply or the maximum gas flow achievable without causing...
01:30Alterations in Respiration II
There are numerous types of normal and abnormal respiration. Based on ventilatory movements, breathing patterns are classified as regular, deep, or shallow. Examples include Biot's breathing, Cheyne-Stokes respiration, Kussmaul's breathing, hyperventilation, and hypoventilation. Each pattern is clinically significant and aids in evaluating patients.
In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes include...

01:25Hyperpnea and Hyperventilation
Hyperventilation refers to a higher-than-normal rate and depth of breathing, often associated with anxiety attacks. This excessive breathing surpasses the body's need to expel CO2, leading to a condition known as hypocapnia - an unusually low level of carbon dioxide in the blood. Hypocapnia can constrict cerebral blood vessels, reducing blood flow to the brain, which may result in dizziness or fainting. Early signs include tingling and muscle spasms in the hands and face, caused by falling...
01:14Spinal Cord Injury ll: Pathophysiology
Spinal cord injury progresses through two interconnected phases: primary injury and secondary injury.Primary InjuryPrimary injury happens at the moment of trauma and involves immediate mechanical damage to the spinal cord.Compression happens when broken vertebrae, herniated discs, or accumulating blood (such as a hematoma) press directly against the spinal cord, distorting its normal shape and function. In cases of contusion, the cord is bruised by a blunt force (like penetrating injuries or...
