  1. 6. Initiation of spleen contraction resulting in natural blood boosting in humans

    Författare :Angelica Lodin; Erika Schagatay; Mats H. Linér; Mittuniversitetet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acclimatization; altitude; apnea; breath-hold diving; hemoglobin; hypercapnia; hypoxia; triggers;

    Sammanfattning : The spleen has been shown to contract in apneic situations in humans as well as in other diving mammals, expelling its stored red blood cell content into circulation. This natural blood boosting may increase the circulating hemoglobin concentration (Hb) by up to 10%, which would enhance the oxygen carrying capacity and likely increase performance. LÄS MER

  3. 7. Hypoxic Blackout in Serial Freediving – Protective Mechanisms and Risk Factors

    Författare :Frank Pernett; Erika Schagatay; Glenn Björklund; Anton Westman; Mittuniversitetet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; breath-hold diving; diving response; hyperventilation; hypoxia; oxygen saturation; oxygen stores; pulse oximetry; sonography; splenic contraction.;

    Sammanfattning : Breath-hold diving or freediving exposes the body to stressors such as low oxygen and high carbon dioxide levels in the blood, increased hydrostatic pressure, and cold. The reduction in blood oxygen levels is considered a primary factor for loss of consciousness while diving. This is known as hypoxic blackout. LÄS MER
