Firstly, as the air enters the lungs, it is humidified by the upper airway and thus the partial pressure of water vapour 47 mmHg reduces the oxygen partial pressure to about 150 mmHg. The rest of the difference is due to the continual uptake of oxygen by the pulmonary capillaries , and the continual diffusion of CO sub 2 sub out of the capillaries into the alveoli. The alveolar pO sub 2 sub is not routinely measured but is calculated from blood gas measurements by the Alveolar gas equation .

They operate by causing a build up of fluids in the lungs which then leads to Asphyxia suffocation . Exposure to the eyes and skin tend to be corrosive, causing blurred vision and severe deep burns. Inhalation of these agents cause burning of the throat, coughing, vomiting, headache, pain in chest, tightness in chest, and respiratory and circulatory failure. Examples of pulmonary agents include chlorine Chlorine gas Chloropicrin PS Diphosgene DP Phosgene CG Disulfur decafluoride Perfluoroisobutene Acrolein Diphenylcyanoarsine Phosgene is the most dangerous commonly used pulmonary agent although disulfur decafluoride and perfluoroisobutene are both even more dangerous, with respectively 4 and 10 times the lethality of phosgene, neither is widely used . It is a colorless gas under ordinary conditions. It has a vapor density 3.4 times greater than that of air allowing it to remain low in the air for long periods of times. Phosgene leads to massive pulmonary edema, which reaches maximum symptoms in 12 hours after exposure followed by death within 24 48 hours. Chlorine is an element used in industry.

A pulmonary tractotomy is a surgical technique to treat a penetrating lung injury . The tract of the lung injury is opened, and open bronchi and blood vessels are ligated sewn . Treatment of penetrating lung injuries Emergency surgery for a penetrating lung injury, e.g. an accident or a gunshot, is associated with a very high mortality rate . Such lung injuries cannot be treated with simple surgery they cannot be oversewn. If treated with simple surgery, blood vessels within the tract of the lung injury may continue to bleed and result in a haematoma which should be avoided. Or the patient may suffer a pulmonary air embolism and subsequently die. Penetrating lung injuries can be treated with a formal lung resection, or with pulmonary tractotomy. Comparison of treatments Pulmonary tractotomy is a lung sparing technique. It can prevent the need for formal lung resection. Its advantages over segmental lung resection include that it can be performed quicker it offers a rapid way to control bleeding haemorrhage and air leaks in patients with penetrating lung injuries. Also, pulmonary tractotomy can preserve healthy pulmonary tissue parenchyma this naturally is not possible with lung resection. ref Pulmonary tractotomy with selective vascular ligation for penetrating injuries to the lung.
