It is possible for trauma to cause clotting problems even without resuscitation efforts.Damage control resuscitation is based on three principles:

permissive hypotension: tries to balance temporary suboptimal perfusion to organs with conditions for halting blood loss by setting a goal of 90 mmHg systolic blood pressure 
hemostatic resuscitation: restoring blood volume in ways (with whole blood or equivalent) that interfere minimally with the natural process of stopping bleeding. damage control surgery. Signs and symptoms
Symptoms of hypovolemic shock can be related to volume depletion, electrolyte imbalances, or acid–base disorders that accompany hypovolemic shock.Patients with volume depletion may complain of thirst, muscle cramps, and/or orthostatic hypotension. Severe hypovolemic shock can result in mesenteric and coronary ischemia that can cause abdominal or chest pain. Agitation, lethargy, or confusion may characterize brain mal-perfusion.Dry mucous membranes, decreased skin turgor, low jugular venous distention, tachycardia, and hypotension can be seen along with decreased urinary output. Patients in shock can appear cold, clammy, and cyanotic.Early signs and symptoms include tachycardia given rise to by catecholamine release; skin pallor due to vasoconstriction triggered by catecholamine release; hypotension followed by hypovolaemia and perhaps arising after myocardial insufficiency; and confusion, aggression, drowsiness and coma caused by cerebral hypoxia or acidosis. Tachypnoea owing to hypoxia and acidosis, general weakness caused by hypoxia and acidosis, thirst induced by hypovolaemia, and oliguria caused by reduced perfusion may also arise.Abnormal growing central venous pressure indicates either hypotension or hypovolemia.
Oral appliances
Oral appliances to protrude the tongue and lower jaw forward have been used to reduce sleep apnea and snoring, and hold potential for treating UARS, but this approach remains controversial. Oral appliances may be a suitable alternative for patients who cannot tolerate CPAP. Surgery
For nasal obstruction, options can be septoplasty, turbinate reductions, or surgical palate expansion.Orthognathic surgeries that expands the airway, such as Maxillomandibular advancement (MMA) or Surgically Assisted Rapid Palatal Expansion (SARPE) are the most effective surgeries for sleep disordered breathing. MMA is often completely curative.Though less common methods of treatment, various surgical options including uvulopalatopharyngoplasty (UPPP), hyoid suspension, and linguloplasty exist. These procedures increase the dimensions of the upper airway and reduce the collapsibility of the airway. One should also be screened for the presence of a hiatal hernia, which may result in abnormal pressure differentials in the esophagus, and in turn, constricted airways during sleep. Palatal tissue reduction via radiofrequency ablation has also been successful in treating UARS. Maxillary Expansion
Orthodontic treatment to expand the volume of the nasal airway, such as nonsurgical Rapid Palatal expansion is common in children. Due to the ossification of the median palatine suture, traditional tooth-born expanders cannot achieve maxillary expansion in adults as the mechanical forces instead tip the teeth and dental alveoli. Mini-implant assisted rapid palatal expansion (MARPE) has been recently developed as a minimally invasive option for the transverse expansion of the maxilla in adults.
