    Study Notes

    Persistent Vegetative State (PVS)

    • Individuals in PVS lose higher brain functions (cortex) but retain basic life functions due to an undamaged brain stem.
    • Essential functions such as heart rate and respiration continue despite the absence of awareness and cognitive abilities.
    • Patients may exhibit physical signs like eyelid movement, sleep-wake cycles, reflex actions, and involuntary vocalizations.

    Terry Schiavo Case Overview

    • Terry Schiavo spent approximately 15 years in PVS after a cardiac arrest in 1990 caused severe brain damage due to oxygen deprivation.
    • Her case became highly publicized, triggering a legal battle between her husband and parents over her right to die.
    • In 1995, her husband requested legal permission for her to discontinue life support, leading to a series of court proceedings.
    • The case went through various legal channels, including federal court, Congress, and the U.S. Supreme Court.
    • Attempts by Florida's governor and the president to intervene and keep Schiavo alive raised significant media attention concerning the right to die vs. right to live.
    • U.S. law permits the cessation of artificial nutrition and hydration in certain circumstances, reinforced by the Schiavo case.

    Outcome and Medical Findings

    • Life-sustaining equipment was removed, leading to her death; an autopsy revealed significant brain atrophy, with the brain weighing less than half its normal size.
    • This finding indicated that no treatment could have restored her consciousness and awareness.
    • PVS individuals are considered biologically alive even without cognitive function or awareness.
    • U.S. courts necessitate authoritative medical evaluations confirming recovery is impossible before allowing the termination of life-prolonging measures.

    Persistent Vegetative State (PVS)

    • PVS results when higher brain functions (cortex) are lost, while the brain stem remains undamaged, sustaining essential functions like heart rate and respiration.
    • Individuals in PVS are biologically and legally alive despite lacking awareness and cognitive capacities.
    • Possible indications of PVS include opening eyelids, sleep-wake cycles, reflexive actions, random facial expressions, and vocalizations.

    Terry Schiavo Case

    • Terry Schiavo suffered cardiac arrest in 1990 due to severe oxygen deprivation, leading to a prolonged vegetative state.
    • Spent nearly 15 years in a PVS before the legal debates regarding her right to die commenced.
    • Controversy arose between her husband, who sought to terminate life support, and her parents, who opposed it.
    • In 1995, her husband legally requested to discontinue her artificial sustenance.
    • The case traversed federal court, Congress, and the U.S. Supreme Court, showcasing state and federal disputes on the right to die.
    • Media portrayed the case highlighting the dichotomy between the right to die and the right to life.

    Implications of U.S. Law

    • The Schiavo case affirmed U.S. law allows discontinuation of artificial food and water under specified conditions.
    • The Vatican opposed the termination of life-sustaining measures.
    • Ultimately, life support was removed, leading to her death, confirmed by autopsy indicating a severely atrophied brain that weighed less than half its normal size.
    • PVS is categorized as biologically alive, lacking conscious awareness, with the brain stem still functioning.
    • Courts permitted the removal of life-sustaining care upon medical authority confirming the impossibility of recovery.
    • PVS blurs the lines of legal death definitions, as individuals are not considered technically dead under whole brain death criteria while the brain stem is intact.
    • The case highlighted significant ethical and legal dilemmas surrounding life support and the classification of death.

    Persistent Vegetative State (PVS)

    • Individuals in PVS have lost higher brain functions while their brainstem remains intact, allowing basic life functions (heartbeat, respiration) to continue.
    • Patients may show limited signs of life like opening eyelids, sleep-wake cycles, and spontaneous vocalizations, yet lack awareness or cognitive capacity.

    Terry Schiavo Case

    • Terry Schiavo spent 15 years in a persistent vegetative state after a cardiac arrest in 1990 led to significant brain damage due to oxygen deprivation.
    • The case became heavily publicized due to legal and ethical debates surrounding her right to die.
