First be sure the blood is coming from the lung and inferior respiratory system not from stomach ( blood mixed with food )or from sinuses,nose (blood in mask).
The tree main diagnoses regarding hemoptysis ( blood coming out of the lungs an inferior respiratory system = bloody sputum ) shortly after surfacing is :
- (1) Pulmonary barotrauma.
- (2) Pulmonary edema after diving.
- (3) Chokes might also be considered.
(1)symptoms are : Bloody from nose or month, Chest pain, Hemoptysis (bloody sputum).
Paralysis or weakness, convulsions, neurological abnormalities may occur in arterial gas embolism.
Sub-coetaneous emphysema or pneumothorax often also happens.
(2) symptoms are : cough, shortness of breath, hemoptysis, disappear within 24 hpurs after a dive
(3) You wont be alive...
Regarding diving medicine (1) Pulmonary barotrauma should be likely.
(2) Is rare but occur in salt water and when immerged and having cardiac problems.
(3) Happen when performing a fast ascent from very deep. (plenty of bubbles within venous pulmonary system ).
But dont forget there are other causes 'non DIVING RELATED' that can cause it ( not only cancer...)
You should really take care of that and visit a diving physician to rule out a diving related injury (sinus probems...)
But (1) (2)(3) usually leave some remarkable sequels.
Unless you may have experienced a pneumothorax without any other manifestation than hemoptysis.
You should really take care of that and visit a diving physician to rule out a diving related injury.
You should get physical and at least a chest X-ray and/or CT-Scanner if not bronchoscopy.
How are you, did you dive since that problem occurred?
If yes how was it???
If not then visit a doctor first.
Take in consideration what Rick Murchison said above.
