Question

does tachypena or bradypena cause hypoxoxemia ? explain why

Answer 1

Answer:

In an adult, The normal breathing rate seen is 12 - 20 breaths per minute.

Tachypnea is a rapid and shallow breathing and is more than 20 breaths per minute. it doesnot cause Hypoxemia .

Bradypnea is an abnormally slow rates of breathing that  less than 8- 10 breaths per minute in adults and below 16 breaths per minute in infants . The slowing respiration is due to the prolongation of Expiratory duration and severe Bradypnea causes reducing Alveolar ventilation leads to Hypoxemia, Respiratory acidosis.  That means  if breathing rate falls too low for too long leads to cause Hypoxemia. Hypoxemia means the presence of the abnormal low level of oxygen in the blood.

-- The brainstem present at the base of brain and its duty is controlling breathing. The process of bringing air into lungs is decreases leads to Bradypnea caused by the use of Opioid drugs, Hypothyroidism , Toxins or head injury.

-- The opioid drugs  attaches to receptors in the central nervous system and it slows the breathing rate and develops into danger for life  and leads to stop breathing.

---the Thyroid glands are not active results in the deficiency of Thyroid hormones and if it is untreated leads to slow down the body mechanisms. it also weakens the muscles leads to decrease in breathing rate and it leads to decrease lung capacity which affects breathing develops Bradypnea.

--Certain chemical toxins when inhaled affects and slow both central nervous system and cardiac system leads to slow down breathing rate. After the chemical gases are absorbed into lungs and reached to bloodstream which results in lower oxygen levels in blood .

--The pressure increases in brain results in Bradycardia when any injury happen to brainstem that  means decreased heart rate and Bradypnea .

if breathing rate falls too low which means below than normal  for longer period of time that  leads to cause Hypoxemia.

If Hypoxemia is not treated and it left like that can lead to Type 1 Respiratory failure which leads to further symptoms of life threatening diseases like:

--Rsepiratory Acidosis,

--Cardiac arrhythmia,

--Cerebral hypoxemia,

--Altered mental state of coma,

--Cardiorespiratory arrest.
