Answer:

Respiratory alkalosis

Explanation:

Hyperventilation is one of the causes of respiratory alkalosis. This patient has a respiratory rate of 48 cycles per minute, due to the rapid breathing there is excessive loss of CO2 which required for the production of H ion leading to loss of acid. The values above shows that there is high pH (alkalosis), low PaCO2 (hypocapnia), low PaO2 (hypoxaemia) and the bicarbonate is within normal.
