It doesn’t look like but over time this position is hard to maintain ! Especially if a rebreathing bag is added 😈🔥 #BDSM #gayBDSM #slave #slaveboy #master #bondage #gaybondage #breathcontrol #breathplay #hood #rebreathing #titclamps #predicament

Scientists cured hiccups by putting a plastic bag over the person's head. The research aimed to determine the level of inhaled CO2 required to stop hiccups. A 20 L (4-gallon) bag was placed over the head, sealed around the neck, and inflated with air. As the person breathes, oxygen saturation is monitored with a pulse oximeter, and CO2 is monitored with a mouth CO2 sensor. In another experiment, there were some small holes in the bag. In another, the bag was filled with pure oxygen. The research showed that, for hiccups to stop, inhaled and exhaled CO2 concentrations had to equalize and then rise together to approximately 50 mmHg. The equalization indicates that the body can no longer expel CO₂ — meaning arterial blood CO₂ (PaCO₂) has caught up with venous blood CO₂ (PvCO₂). In experiment 1, this happened around 3 minutes, and the hiccups stopped. In experiment 2 (the bag with holes), it didn’t happen, and the hiccups didn't stop. In experiment 3 (the bag filled with oxygen to start with), both occurred around 6 minutes. “We stumbled upon the observation that acute CO2 retention induced by plastic bag rebreathing resolves persistent hiccups. This discovery is actually quite similar to the results achieved by other Japanese researchers during experiments using felines when they indicated that CO2 inhalation suppresses the movements of the muscles associated with hiccups... The mechanism behind our method is simple: hiccups stop when the partial pressure of CO2 in arterial blood (PaCO2) reaches the same level as that in venous blood (PvCO2), or approximately 50 mm Hg.” The required threshold of CO2 concentration is only slightly above what you'd normally exhale, but massively higher than what you'd normally inhale. Normal atmospheric CO₂ = ~0.04% (about 0.3 mmHg) Normal exhaled CO₂ (EtCO₂) = ~5% (~38 mmHg) The target in this paper = ~6.6% (~50 mmHg) Of course, putting a plastic bag over your head is a bad idea, but rebreathing into a paper bag can have the same effect without the risk of suffocation.
