An update on the OFCOM situation: As you know, censorship around the world has been ramping up at an alarming pace. OFCOM, the UK’s communications regulator, has singled out our community, demanding compliance with their Online Safety Act despite our minimal UK presence. This is a blatant overreach, and they have been sending letters pressuring us to comply with their censorship agenda.
Our platform is already blocked by many UK ISPs, yet they continue their attempts to stifle free speech. Standing up to this kind of regulatory overreach requires lots of resources to maintain our infrastructure and fight back against these unjust demands. If you value our community and want to support us during this time, we would greatly appreciate any and all donations.
The "fainting lark" consists of squatting in a full knee bend and hyperventilating. The subject then stands up suddenly and performs a forced expiration against a closed glottis. The procedure combines the effects of acute orthostatic stress, straining and hyperventilation. The latter doubles skeletal muscle blood flow and halves cerebral blood flow. The maneuver provokes a precipi- tous fall in finger arterial pressure and diastolic cerebral blood flow velocity suddenly drops to zero (Fig. 1). The subject rapidly loses consciousness and collapses with- out warning symptoms. In the supine position systemic blood pressure and cerebral blood flow velocity are rapidly restored and the subject regains consciousness. The "fainting lark" has been used by children, high school students and recruits as entertainment for their friends (Howard, 1951), but also as a research tool to study the sequence of clinical events during syncope (Lempert, 1994). The time course of the hemodynamic events involved in the "fainting lark" is much more abrupt than it is in spontaneous vasovagal syncope.
