Hyperventilation can occur in neck breathers including laryngectomees. Hyperventilation reduces the level of carbon dioxide in the blood. It can upset the acid-base balance in the blood making it more alkaline. The syndrome is characterized by repeated episodes of excessive ventilation in response to fear, anxiety or panic. It can also occur during an orgasm or intense sexual activity, as well as heavy physical activity.
Neck breathers are more prone to this condition because
rapid breathing ventilate the lungs quicker than in non-neck breathers as the
inhaled air enter the trachea through the stoma, bypassing the upper airways.
The existence of hyperventilation in laryngectomees was evaluated by Brook by sending a questioner to 256 laryngectomees. Fifty-four of the 72
individuals who return the questioner experienced one or more episodes of
hyperventilation. It was associated with heavy physical activity in 28 (51%)
individuals, sexual activity in 15 (38%), anxiety in 8 (15%), and intense
coughing in 7 (13%). The symptoms experienced were: fast or deep breathing in
all cases, shortness of breath (50 or 96%); anxiety, fear, panic, or strong
feeling of dread or doom (38 or 70%); dizziness (27 or 50%); generalized
weakness (16 or 30%); sweating (13 or 34%); fainting (4 or 7%); and chest pain
(4 or 7%).
This small survey illustrates that laryngectomees do experience
hyperventilation syndrome.
Further studies are warranted to prospectively evaluate the
incidence of hyperventilation in laryngectomees and other neck breathers. Such
studies may highlight the need to address, prevent and treat this condition in
laryngectomees.
