Question
Chapter 22, Problem 3TYC
Summary Introduction
Summary:
During swimming competition most swimmers hyperventilate before the race to load up extra oxygen (O2) so that they could hold under water for longer duration. The reason for longer holding of the breath is not what they think. Some swimmers due to such practices have lost consciousness and drowned during such processes. The reason for such wrong thinking and the reason for loss of consciousness are discussed.

Some competitive
swimmers hyperventilate
before a race, thinking they
can "load up on extra
oxygen" and hold their
breaths longer underwater.
While they can indeed hold
their breaths longer, it is not
for the reason they think.
Furthermore, some have
lost consciousness and
drowned because of this
practice. What is wrong
with this thinking, and what
accounts for the loss of
consciousness?
Consider the following situation:
You try to hold your breath for as long as you can, but you can do so only for about a minute voluntarily.
Eventually, you can hold your breath no longer, and you start breathing involuntarily.
Which parts of the brain are involved in the two actions?
What is the physiologic process involved in the regulation of respiration?
a)Some competitive swimmers hyperventilate before a race, thinking they can "load up extra oxygen" and hold their breaths longer underwater. While they can indeed hold their breaths longer, it is not for the reason they think. Furthermore, some have lost consciousness and drowned because of this practice. What is wrong with this thinking, and what accounts for the loss of consciousness?
b) You cannot affect the oxygen delivery to your tissues by drinking "oxygenated water". However, breathing oxygen at hyperbaric pressures increases oxygen delivery to tissues. Explain why these two statements are true.

- Daniel, the swimmer with the fastest time on the college swim team, routinely hyperventilates before a meet, as he says "to sock some more oxygen into my lungs so I can swim longer without having to breathe." "Furthermore, my heart won't have to adjust it's output". First of all, what basic fact about oxygen loading has Daniel forgotten (a lapse leading to false thinking)? Do you think that hyperventilation will provide him with enough oxygen to increase his endurance during the race?arrow_forwardWhich of the following statements about type I respiratory failure is correct? CNS depression with reduced respiratory drive can lead to type I respiratory failure. The partial pressure of carbon dioxide in the arterial blood is above 45 mmHg. It is caused by gas-exchange respiratory failure. Medical ventilator should be used in patients with type I respiratory failure. Hypercapnia occurs prior to hypoxemia.arrow_forwardWhich one of the following statements about the afferent components of the respiratory control system is INCORRECT? Select one: a. In order to stimulate hyperventilation the sympathetic nervous system tricks the carotid body by constricting the capillaries that serve glomus cells; reduced blood flow to the cell causes localised hypoxia triggering a compensatory hyperventilation response even before systemic hypoxia is apparent. b. In type 1 glomus cells of the carotid bodies, hypoxia, hypercapnia and acidosis trigger afferent signalling by inhibiting K+ channels, depolarising the cell membrane, and opening voltage-gated Ca2+ channels that trigger the release of neurotransmitters onto afferent glossopharyngeal nerve fibres. c. Chemoreceptor cells can be found in the carotid body. d. The glossopharyngeal nerve transmits afferent impulses from the carotid body to the ventral respiratory group of neurons.arrow_forward
